Invertebrate pest control within both agricultural and horticultural production systems continues to present many challenges. Over the past decades the commonly used method for pest control has been the direct application of chemical products. However, in response to environmental, economic, and other problems associated with the over-reliance on chemical insecticides there has been an increasing drive towards the development of Integrated Pest Management (IPM) approaches. Many IPM strategies are now well developed under protected environments. However, within the open field in many situations targeted success is yet to be achieved. This special issue will seek to showcase original articles and reviews by leading research entomologists and associated experts. Articles presented will focus on the development and implementation of IPM strategies against various major arable and horticultural invertebrate pests (both indigenous and invasive species).

Farmer field schools (FFSs) were conducted in southern India to reduce pesticide input and enhance sustainability of cotton production systems. This study was carried out to determine the additional benefits of FFSs in the social and economic arena, using the sustainable livelihoods (SL) concept to frame the evaluation. Farmers who had participated in the integrated pest management (IPM) FFSs perceived a range of impacts much beyond the adoption of IPM practices. The reduced cost of cultivation allowed for financial recovery from debt and the building of physical assets. IPMFFS households and production systems were perceived by the participants to have become more economically resilient than Non-IPMFFS control groups when faced with adversity. In the participants' view, IPMFFSs also led to enhanced individual and community social well-being, a benefit valued in particular by the women participants. The study tested a new application of the SL conceptual framework as a tool for evaluation.

Agricultural production systems are a composite of philosophy, adoptability, and careful analysis of risks and rewards. The two dominant typologies include conventional and organics, while biotechnology (GM) and Integrated Pest Management (IPM) represent situational modifiers. We conducted a systematic review to weigh the economic merits—as well as intangibles through an economic lens—of each standalone system and system plus modifier, where applicable. Overall, 17,485 articles were found between ScienceDirect and Google Scholar, with 213 initially screened based on putative relevance. Of those, 82 were selected for an in-depth analysis, with 63 ultimately used. Economically, organic generally outperformed conventional systems. This is largely due to their lower production costs and higher market price. However, organic farms face lower yields, especially in the fruit, vegetable, and animal husbandry sectors. With that said, organic farming can provide significant local environmental benefits. Integrated pest management (IPM) is a potentiator of either core system. As a risk reduction and decision-making framework, it is labor intensive. However, this can be offset by input reductions without yield penalty compared to a conventional baseline. Biotechnology is a rapidly emerging production system, notably in developing countries. The use of GM crops results in lower production cost and higher yields. As a conventional modifier, its major advantage is scale-neutrality. Thus, smaller and lower income farmers may achieve higher gross margin. The main source of environmental benefits is reduced pesticide use, which implies a decreased need for fuel and labor. Barring external influences such as subsidies and participation in prescriptive labeling programs, farmers should focus on an a la carte approach (as opposed to discrete system adoption) to optimize their respective enterprises.

Potato (Solanum tuberosum L.) is an important food crop worldwide. As the demand for fresh and processed potato products is increasing globally, there is a need to manage and control devastating diseases such as zebra chip (ZC). ZC disease causes major yield losses in many potato-growing regions and is associated with the fastidious, phloem-limited bacterium Candidatus Liberibacter solanacearum (CLso) that is vectored by the potato-tomato psyllid (Bactericera cockerelli Šulc). Current management measures for ZC disease mainly focus on chemical control and integrated pest management strategies of the psyllid vector to limit the spread of CLso, however, they add to the costs of potato production. Identification and deployment of CLso and/or the psyllid resistant cultivars, in combination with integrated pest management, may provide a sustainable long-term strategy to control ZC. In this review, we provide a brief overview of the ZC disease, epidemiology, current management strategies, and potential new approaches to manage ZC disease in the future.

Due to the high susceptibility of strawberry fruits to the attack of pests and diseases, a large amount of pesticides is applied during the crop cycle and harvest period. The inadequate use of these substances can generate residuals in agricultural products, which, through intake, pose a risk to human health. The objective of this study was to determine and compare the pesticide residues in strawberry fruits from two different production systems, distributed in the main producing areas of the Cundinamarca Department (Colombia). Eight samples of strawberry crops were collected in four producer municipalities (Guasca, Facatativa, Mosquera and Sibate), two to compare different systems (conventional production vs. production based on the Integrated Pest Management, IPM). Samples at a concentration of 394 molecules were examined by liquid and gas spectrometry. Fisher's exact test was used to determine the association between crop practices and the residual level in fruits. Twenty two different molecules were detected for the samples analyzed, with 37 detection events, of which eight were reported in IPM production systems and 29 in conventional producers. Results revealed a total of two molecules at excessive concentrations after Colombian regulations. Significant differences were found between the two production systems. This is attributable to the producers´ lack of knowledge and understanding about conventional management in Good Agricultural Practices, and the concepts of pesticide restriction period and residuality.

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
