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...

Ecological modeling is an important tool for investigating dynamic behavior patterns in populations, trophic interactions, and behavioral ecology. However, the ecological patterns that reflect population oscillation trends are often not clearly visible without analytical instruments such as ecological models. Thus, ecological modeling plays a fundamental role in describing demographic processes that are important for population dynamics. Ecological models, besides making possible the visualization of ecological patterns, may also reveal patterns of population persistence in many trophic systems, including prey-predator or host-parasitoid relationships, interactions that are commonly present in integrated pest management programs. In this forum, we present the main ecological aspects important for model building and implementation of integrated pest management programs for insects. Particularly, in this study, we analyze the combination between host-parasitoid models and the concept of economic threshold level on a spatio-temporal scale. As a conclusion about the model combination, spatial structure is essential for models of this nature, since its introduction into the system significantly alters the economic threshold-level values.; A modelagem ecológica é uma ferramenta importante para a investigação de padrões de comportamento dinâmico em populações...

Seletividade de inseticidas utilizados na cultura dos citros ao predador Ceraeochrysa cubana (Hagen, 1861) (Neuroptera: Chrysopidae), desenvolvimento em diferentes temperaturas e diversidade de crisopídeos em propriedades com manejo intensivo e convencional de Diaphorina citri Kuwayama (Hemiptera: Liviidae); Selectivity of insecticides used in citrus groves to the predator Ceraeochrysa cubana (Hagen, 1861) (Neuroptera: Chrysopidae), development in different temperatures and lacewing collections in orchards under intensive and conventional management systems of Diaphorina citri Kuwayama (Hemiptera: Liviidae)

O crisopídeo Ceraeochrysa cubana (Hagen, 1861) é um importante predador na cultura dos citros. Apesar da grande importância de C. cubana, pouco se conhece sobre a biologia e o efeito dos inseticidas a este crisopídeo, o que seria fundamental para um programa de Manejo Integrado de Pragas. Com essa pesquisa objetivou-se avaliar o efeito: a) letal e subletal de inseticidas aplicados sobre ovos com 3 idades diferentes; b) letal e subletal de inseticidas sobre larvas de primeiro instar; c) letal e subletal de inseticidas aplicados sobre pupas e adultos; d) do manejo de Diaphorina citri Kuwayama (Hemiptera: Liviidae) na população de crisopídeos; e) de seis temperaturas sobre a biologia de C. cubana. Verificou-se que não houve diferença significativa das variáveis avaliadas entre os tratamentos, dentre os ovos com 24, 72 e 120 horas. O produto Lorsban® 480 BR afetou a viabilidade dos ovos das três idades e foi o inseticida que mais afetou o predador quando aplicado sobre os ovos, classificado como moderadamente nocivo (classe 3). Em larvas, os inseticidas Lorsban® 480 BR e Malathion® 1000 EC tiveram efeito letal, causando 100% de mortalidade 24h após a aplicação e os inseticidas Azamax® e Engeo Pleno® foram os únicos produtos que tiveram efeito subletal sobre as pupas oriundas das larvas tratadas e nenhum dos produtos testados foram classificados como inócuos (classe 1) ao predador. Nenhum dos inseticidas testados teve efeito letal e subletal quando aplicados sobre as pupas...

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...

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 expression "Integrated Pest Management" (IPM or MIP in Portuguese) is completing 28 years since it first appeared in press. Since then integrated pest management or integrated pest control has become the paradigm of choice for activities that aim at attenuating the impact of all pests - plant diseases, weeds, and invertebrate or vertebrate animals - in agricultural production, in human and animal health, and in urban or rural structures. Despite the nearly universal acceptance of the concept, its practical application still is rather restricted, varying considerably among geopolitical regions, the nature of the crop, and, mainly, with the commitment and support of responsible governmental entities for programs dedicated to promote adoption of IPM. An objective assessment of the successful incorporation of IPM in agricultural practices is difficult because: a) lack of rigorous criteria to distinguish an IPM program from other traditional pest control activities, b) absence of a broadly based consensus on a definition of IPM, and c) paucity of reliable quantitative surveys of the agricultural area under IPM. Some have used the percentage of pesticide use reduction as a measure of the success of IPM. This measure, however, in the absence of other criteria...

An Integrated Pest Management is formulated as a threshold policy. It is shown that when this strategy is applied to a food web consisting of generalist, specialist predators and endemic and pest prey, the dynamics can be stable and useful from the pest control point of view, despite the dynamical complexities inherent to the application of biocontrol only. In addition, pesticide toxicity depends rather on the species intrinsic parameters than on the chemical agent concentration.

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.

Integrated pest management and organic farming are alternatives for sustainable agriculture and less pesticide use in the European Union. All professional users of pesticides in the European Union should follow the general principles of integrated pest management from 2014. States should report to the European Commission on their national action plan for the effective application of those those general principles through crop-specific guidelines. The major remaining issues are: (1) when guidelines are not already applied, what incentives would encourage European farmers to adopt those guidelines? (2) How and to what extent should public money be used to promote the adoption of guidelines? Here, we review the adoption of integrated pest management in Europe. We deliver a framework to understand the drivers of changes in farmers’ pest management practices. This framework also helps to understand farmer reaction to different policy incentives.; JRC.J.4-Agriculture and Life Sciences in the Economy

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.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Urban pests are known to infest health service facilities, especially in a warm, wet neotropical climate. In practice, pest control services for health service facilities are generally outsourced and in most cases are not properly monitored. To address this problem, an integrated pest management (IPM) programme was developed at a hospital in the municipality of Botucatu, state of Sao Paulo, Brazil, by the infection control committee. The method of control applied used spreadsheet pest reports to monitor the presence of vectors. These reports were forwarded to the committee and used to implement several actions of integrated pest control. In 2011, a total of 183 occurrences were recorded by the infection control committee, 5% lower than the number of incidents recorded in 2010, the first year of integrated pest control. In 2012, the total number of occurrences decreased to 159 events, demonstrating the IPM effects. Three years after the implementation of the programme, the predominant pests in the hospital were scorpions (30%), ants (19%) and spiders (16%), with Tityusserrulatus, Paratrechinalongicornis and Loxosceles sp as the predominant species, respectively. The presence of scorpions in a hospital environment is not documented in the literature...

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...
