The black scale, Saissetia oleae (Olivier) (Hemiptera Coccidae), is one of the main olive pests and coccinellids are among the principal predators that feed on scales. The relationships between the temporal abundance of five common coccinellid species [Chilocorus bipustulatus L., Scymnus subvillosus (Goeze), Scymnus mediterraneus Iablokoff-Khnzorian, Scymnus interruptus (Goeze), Rhyzobius chrysomeloides (Herbst)] and the different phenological stages of S. oleae were investigated in two olive groves managed under two different systems (Integrated Pest Management and Organic Farming) during 2002 and 2003. Coccinellids and black scale were randomly sampled on a fortnightly basis and correlation analyses between the abundance of the coccinellid species and the different stages of the pest were carried out. Results showed that the abundance of S. oleae was similar between olive groves and years. However, significant differences were found for adult and larvae of coccinellid species. In both years and groves, the greatest abundance of coccinellids occurred between June and November, also corresponding to the period of greatest abundance of the first and second instar nymphs of S. oleae. Significant positive correlations were obtained between the second instar nymph and four out of five coccinellid species...

O presente estudo foi desenvolvido com 22 espécies de insetos sugadores e seus controladores em citros, na fazenda Cambuhy, município de Matão, estado de São Paulo, Brasil, durante o período novembro de 2004 a abril de 2006. Inicialmente foram determinados os indicadores ecológicos desse agroecossistema e feita a avaliação da diversidade de espécies nos três sistemas de controle sendo, controle microbiano de pragas (CMP) com uso de fungos entomopatogênicos, manejo ecológico de pragas (MEP) com uso de agrotóxicos seletivos a fungos entomopatogênicos, e manejo integrado de pragas (MIP) com uso padrão de pesticidas. Determinou-se que a diversidade foi maior no CMP e que os sistemas MEP e MIP foram semelhantes (80%) e não ocorreu impacto ambiental nos três sistemas, em função dos períodos de observação. Orthezia praelonga, no período total de seis estações, foi controlada nos tratamentos CMP e MEP, pelos fungos Syngliocladium sp. e Lecanicillium longisporum , com maior prevalência do primeiro e comportamento distinto dos dois entomopatógenos nas diferentes estações. Dialeurodes citri foi o principal hospedeiro de Aschersonia aleyrodis com mais de 80% de incidência do patógeno. No sistema MEP determinou-se associação inversa entre população de O. praelonga e o número de unidades formadoras de colônia (UFC) do fungo Lecanicillium obtendo-se...

A lagarta-enroladeira Bonagota salubricola (Meyrick, 1937) e a mariposa oriental Grapholita molesta (Busck, 1916) (Lepidoptera: Tortricidae) são duas das mais importantes pragas de frutíferas de clima temperado no Brasil. O manejo destes insetos-praga tem sido realizado quase que exclusivamente com inseticidas. Para a implementação de estratégias de manejo pró-ativo de resistência, é importante conhecer o estado atual de suscetibilidade destas espécies a inseticidas para detectar a resistência antes que se observem falhas no controle. Nas condições brasileiras, em regiões onde estes pomares são plantados próximos em algumas regiões, acredita-se que G. molesta disperse para a cultura da maçã após a colheita do pêssego, dependendo da proximidade espacial e temporal dos pomares. Portanto, este trabalho teve como objetivos, caracterizar a suscetibilidade de B. salubricola e G. molesta aos principais inseticidas recomendados para o controle e avaliar a estrutura genética de populações de G. molesta provenientes das culturas da macieira e pessegueiro no Brasil. A caracterização da suscetibilidade foi realizada com bioensaio de ingestão com tratamento superficial da dieta com inseticidas, utilizando-se lagartas neonatas provenientes de populações de B. salubricola coletadas em macieira no Estado do Rio Grande do Sul (safra 2011/12) e de G. molesta provenientes de pomares do Rio Grande do Sul (2010/11 e 2011/12)...

O uso de plantas inseticidas e de variedades pode ser forte aliado ao Manejo Integrado de Pragas (MIP), podendo reduzir o número de aplicações de inseticidas e minimizar seus efeitos ao homem e ao meio ambiente. em condições de campo, visando o controle de pragas tardias do tomateiro em duas cultivares de crescimento determinado, compararam-se as seguintes táticas de controle: a) Convencional - pulverizações com os produtos metamidofós, buprofezin, acefato, cipermetrina, abamectina, permetrina, teflubenzuron e lufenuron, aplicados em intervalos de três a seis dias; b) MIP - nível de ação de cada praga para aplicações de imidacloprid, triflumuron, lufenuron e abamectina; c) MIP - Azadirachta indica (nim) - nível de ação de cada praga para aplicações de óleo de nim (1,2% de azadiractina) a 0,5%. As táticas de controle MIP e MIP - nim foram eficientes no controle das pragas tardias do tomateiro, quando a pressão da população é baixa, não diferindo do tratamento convencional que apresentou as menores médias de infestação. As táticas de controle convencional, MIP e MIP-nim promoveram maiores produções do tomateiro, com incrementos de até 74%. O número de pulverizações foi reduzido em até 77% com as táticas MIP e MIP - nim...

According to biological strategy for pest control, we investigate the dynamic behavior of a pest management SEI model with nonlinear incidence concerning impulsive strategy-periodic releasing infected pests at fixed times. We prove that all solutions of the system are uniformly ultimately bounded and there exists a globally asymptotically attractive pest-eradication periodic solution when the impulsive period satisfies A1. When the impulsive period satisfies A2, the stability of pest-eradication periodic solution is lost, the system is uniformly permanent. Thus, we can use the stability of the positive periodic solution and its period to control insect pests at acceptably low levels.

In this paper, we consider the pest management model with spraying microbial pesticide and releasing the infected pests, and the infected pests have the function similar to the microbial pesticide and can infect the healthy pests, further weaken or disable their prey function till death. By using the Floquet theory for impulsive differential equations, we show that there exists a globally asymptotically stable pest eradication periodic solution when the impulsive period τ < τmax, we further prove that the system is uniformly permanent if the impulsive period τ > τmax. Finally, by means of numerical simulation, we showthatwith the increaseof impulsive period, the system displays complicated behaviors.

The usage of insecticidal plants and others insect resistant varieties can be strong allies to the Integrated Pest Management (IPM), being able to reduce the number of insecticides applications and to minimize its effect to the man and the environment.The following control techniques were compared in field conditions, investigating the late pest control of two determinate tomato cultivars: a) Conventional - sprayings of metamidophos, buprofezin, acephate, cipermetrin, abamectin, permetrin, teflubenzuron and lufenuron, applied every three to six days; b) IPM - action threshold of each pest to the spraying of imidacloprid, triflumuron, lufenuron and abamectin; c) IPM - Azadirachta indica (neem) - Action threshold of each pest to the spraying of the nim oil (1.2% of azadirachtin) at a concentration of 0.5%. The IPM and IPM - Neem control techniques were efficient controlling the late pest of the tomato cultivar, not differing from the conventional treatment that presented the lowest levels of infestation. The conventional control technique, IPM and IPM-neem promoted bigger tomato production with increasements of up to 74%. The number of sprayings was reduced up to 77% with the IPM and IPM - neem techniques, when compared to the conventional method. The neem product may be a promising alternative to the late pest control in the tomato field that adjusts to the IPM.

The excessive use of pesticides in Indonesia during the 1970s and 1980s caused serious environmental problems, such as acute and chronic human pesticide poisoning, animal poisoning, the contamination of agricultural products, the destruction of both beneficial natural parasites and pest predators, and pesticide resistance in pests. To overcome these environmental problems, the Indonesian government implemented an integrated pest management (IPM) program from 1991 to 1999. During that time, the program was able to help farmers reduce the use of pesticides by approximately 56% and increase yields by approximately 10%. However, economic literature that analyzes the impact of the IPM program on household incomes and national economic performance is very limited. The general objective of this research is to analyze the impact of the IPM program in food crops on the Indonesian economy and household incomes for different socioeconomic groups.; no

In order to improve the level of adoption of integrated pest management (IPM), it is important to understand the benefits of integrating IPM practices. Integrated systems are less prone to failure and, when they incorporate natural enemies, they are also more resilient than systems that rely on a single method of pest suppression. The impact of changing IPM practices on the pest population dynamics was evaluated in a qualitative manner by varying the parameters of the Lotka-Volterra Model. Factors that reduced the mean population density, reduced the amplitude of pest population fluctuations or increased the interval between pest population peaks were considered to improve IPM systems. Practices that reduce the net reproduction of pests, like resistant plant varieties and promotion of generalist natural enemies, are one way to improve IPM systems. Providing food resources for specialist natural enemies can also improve the level of control. Both broad-spectrum and selective insecticides can disrupt biological control systems that involve specialist natural enemies, so it is important to use pesticides only as a last resort. Even when IPM practices deliver only a fraction of the overall level of control, they can contribute to an effective IPM system. There are many practices that can be incorporated into integrated systems directed at management of the diamondback moth (DBM). Further theoretical and empirical research is needed to assist farmers with the implementation of integrated systems for management of DBM and other pests.

Sponsored Report (for Acquisition Research Program); Should pest management be outsourced on Joint Base Anacostia-Bolling? The researchers of this report argue the cost to outsource may be significantly greater, possibly five times greater, than completing the requirement in-house with federal employees. To in-source and outsource a service requirement for the federal government is sometimes transactional, but when either in-sourcing or outsourcing supports a long-term installation function and impacts mission support, greater analysis is needed before making the decision to outsource. In accordance with congressional legislation, on October 1, 2010, Bolling Air Force Base and Naval Support Facility Anacostia merged to form Joint Base Anacostia-Bolling (JBAB). The installation occupies over 900 acres and requires an extensive pesticide treatment plan. Currently, the level of service for pesticide treatment is different on Bolling than it is on Anacostia. Bolling is staffed with three full-time civil service entomologists who provide effective pesticide treatment for the 136 buildings and 359 acres of land area Bolling occupies. Anacostia has 74 buildings and 607 acres of land area in which only two buildings are fully treated under an existing regional contract. The researchers goal in producing this report is to help the decision-maker choose the best course of action among the following alternatives to meet the expanded pest treatment requirement on JBAB. The following is a list of possible actions explored in the report: ユ_ᆬ absorb the larger requirement into current in-house capacity; ユ_ᆬ outsource the entire pest management and herbicide requirement to a private contractor for all of JBAB; ユ_ᆬ utilize contract services to meet the additional requirement (utilizing hybrid-type contract...

La agricultura urbana en Cuba se ha convertido en una importante fuente de producción de hortalizas y otros productos agrícolas frescos, que se realiza dentro de las ciudades y en su periferia, mediante diversos sistemas de cultivos conocidos como “organopónicos”, huertos intensivos y otros, donde no se permite el empleo de plaguicidas sintéticos para el control de las plagas. Se efectúa un estudio durante los años 2003-2005 en municipios y sistemas de producción representativos de los principales cultivos que se han desarrollado en la agricultura urbana y periurbana de la ciudad de La Habana, mediante un proceso de investigación participativa para caracterizar el manejo de plagas. Se comprueba que los agricultores han realizado innovaciones para adoptar diversas prácticas agroecológicas, principalmente el manejo de la diversidad fl orística, manejo agronómico de cultivos y control biológico, todas a nivel del sistema de producción, lo que le confi ere un enfoque de sistema. Se destacan por su aceptación por los agricultores las rotaciones y las asociaciones de cultivos, las barreras vivas de maíz y otras plantas, utilización de plantas repelentes, las cercas vivas perimetrales con diversos propósitos...

Las estrategias de manejo integrado de plagas (MIP) han estado dominadas por la idea del producto considerado como “la bala mágica’’ para controlar los brotes de plagas. Los enfoques del MIP no han abordado las causas ecológicas de los problemas de plagas en la agricultura moderna. En este articulo se plantea que los problemas de plagas pueden solucionarse mediante la reestructuración del manejo de los sistemas agrícolas, quebrando el monocultivo vía esquemas de diversificación que maximicen una serie de fortalezas preventivas, aprovechando las ventajas inherentes de los agroecosistemas diversificados, usando tácticas terapéuticas que actúan estrictamente como complementos de los procesos de regulación natural. Estos enfoques suponen un conocimiento profundo de los procesos del agroecosistema, incluyendo los factores naturales que suprimen las poblaciones de plagas, con el objetivo final de diseñar sistemas agrícolas a nivel de finca y de paisaje que fomentan los procesos de regulación natural de plagas.; Abstract: The strategies of Integrated Pest management (IPM) have been domintaed by a “magic bullet” mentality to control pest outbreaks.

In Indonesia, demand is growing for food with additional food safety and quality assurances, termed credence attributes. Indonesian food retailers are selling fresh fruits and vegetables labelled as organic and pesticide-free. Some of these claims are underpinned by retailer-mandated food standards, which include specific farming systems that can be verified and certified. If these private sector standards are set too high, smallholders may be excluded from food markets. Additionally, if claims are not certified by a reputable third-party then information asymmetry is an issue. Little is known about the types of food certifications and claims most valued by Indonesian consumers. Chapter 2 addressed the gap in the literature on demand for credence attributes in Indonesia through analysis of data collected as part of a food consumption study of 1180 urban Indonesian households. In the study, consumers indicated their willingness-to-pay (WTP) for three certified food products. Consumers were on average, willing to pay 17 to 19 per cent more for certified organic horticultural products (chillies and mangoes). WTP data was analysed using a Cragg double-hurdle model. The empirical results suggest the target market for certified organic food products in Indonesia is higher educated females who live in higher incomes households and frequently shop in modern food retail outlets (supermarkets). Higher food quality and safety requirements are likely to be a challenge for smallholder farmers in Indonesia. Thus...

At the request of the World Bank's Executive Board, the Bank's Operations Evaluation Department (OED) has been conducting an evaluation of the Bank's involvement in global programs. The Phase 1 Report titled The World Bank's Approach to Global Programs focused on the strategic and programmatic management of the Bank's global portfolio of 70 programs in five Bank Networks (a cluster of closely related sectors) and was presented to the Committee on Development Effectiveness (CODE) on June 12, 2002. This case study is one of 26 and derives additional lessons for the Bank's strategic and programmatic management of global programs as well as lessons for the design and management of individual programs. This case study assesses the value added by the Bank's participation in the Global IPM Facility with a view to learning lessons for the Bank s future involvement in global programs. This is not a programmatic evaluation of the Global IPM Facility, nor a substitute for a thorough external independent evaluation. Several studies using new survey data detailing the substantial health and ecological benefits of IPM have emerged that contend that IPM does not result in a loss in production. Yet the debate continues about the most cost-effective and fiscally sustainable approach to extending knowledge about IPM practices to farmers.

Concerns about the sustainability of conventional agriculture have prompted widespread introduction of integrated pest management (IPM), an ecologically-based approach to control of harmful insects and weeds. IPM is intended to reduce ecological and health damage from chemical pesticides by using natural parasites and predators to control pest populations. Since chemical pesticides are expensive for poor farmers, IPM offers the prospect of lower production costs and higher profitability. However, adoption of IPM may reduce profitability if it also lowers overall productivity, or induces more intensive use of other production factors. On the other hand, IPM may actually promote more productive farming by encouraging more skillful use of available resources. Data scarcity has hindered a full accounting of IPM's impact on profitability, health, and local ecosystems. Using new survey data, the authors attempt such an accounting for rice farmers in Bangladesh. They compare outcomes for farming with IPM and conventional techniques...

The objective of this paper is to: (a) review World Bank's pest management activities during 1999-2004; (b) assess those in view of the changes in the external and internal contexts; (c) identify appropriate opportunities of engagement on pest and pesticide issues; and (d) suggest means to further promote sound pest management in the World Bank operations. The importance of sound pest management for sustainable agricultural production is being recognized by many developing countries. Many countries have adopted sound pest management and Integrated Pest Management (IPM) policies authorizing plant protection services to coordinate the promotion of good practices. These policies provide the institutional framework for the planning and implementation of pest management.

Integrated Pest Management (IPM) is a pest management system that, in the socioeconomic context of farming systems, the associated environment and the population dynamics of the pest species, utilizes all suitable techniques in a compatible manner as possible to maintain the pest population levels below those causing economic injury. This article covers the principal aspects of the interaction between Apis mellifera and Varroa destructor and it describes the classical control forms applied to reduce the mite negative impact on colonies. Some examples of IPM activities that have been done to control this parasite in the southeast of Buenos Aires province, Argentina have shown good results. Several products worldwide have shown good effectiveness as well. Nevertheless, there are certain risks and hazards inherent to their use, such as: their negative impact on human health, resistance phenomena, loss of beneficial insects and native fauna, environmental pollution and drug residues in the hive products harmful for human consumption. The development of acaricide resistance in V. destructor populations and the possibility of incorporating contaminants in colonies by means of this type of treatment have promoted the addition of new molecules to minimize these disadvantages. The application of organic acids...
