Oregon State University (OSU) developed an integrated pest management (IPM) program for hazelnut (Corylus avellana.) in the early 1980s, through a USDA grant. Sampling schemes and action thresholds were refined over a period of 4 years for the filbertworm (Cydia latiferreana), filbert aphid (Myzocallis coryli), filbert leafroller (Archips rosanus.), and obliquebanded leafroller (Choristoneura rosaceana), which are the most important insect pests in Oregon hazelnuts. A classical biological approach was employed in the mid-1980s when the filbert aphid parasitoid, Trioxys pallidus, was imported from Europe. Grower survey results for 1981 and 1997 showed that the amount of pesticides applied for filbert aphid control has declined by 93%. The registration of synthetic pyrethroids for filbertworm control and the use of pheromone trapping have reduced the amount of active ingredient applied in the industry by 96%. The annual cost savings to Oregon hazelnut growers due to use of the OSU IPM program are estimated at $0.5 million. Current research focuses on the use of less toxic insecticides, such as insect growth regulators for filbertworm and leafroller control. The most serious hazelnut disease, eastern filbert blight (EFB) caused by the fungus Anisogramma anomala was first reported in the Pacific northwestern U.S. in 1973. It has spread its way through two thirds of the hazelnut acreage. Current OSU IPM recommendations include preventative fungicide sprays in spring, scouting for and cutting out infections, and replacement of the most susceptible cultivars when possible. The long-term approach to EFB control is the development of EFB immune varieties.

The obliquebanded leafroller (OBLR), Choristoneura rosaceana (Harris) [Lepidoptera: Tortricidae], a primary pest in Quebec apple orchards, can be naturally parasitized. Knowing that habitats around crop’s peripheries are reservoirs for natural enemies of pests, the objective of the present investigation was to assess parasitism and parasitoid guild composition associated with the OBLR. The two-year study included orchards under integrated pest management, their edges, and adjacent woodlands. Parasitism was assessed using sentinel OBLR larvae and considered spring, early summer and late summer. Parasitism rates between regions with different vegetation composition were not significantly different. The first year, late summer larvae showed higher parasitism in orchards (27%), compared to edges (7%) and woodlands (11%). The following year, larvae exposed in early summer had higher parasitism rate in edges (28%) compared to orchards and woodlands (17% in both zones). Nineteen parasitoid species parasitized sentinel larvae. The tachinid Actia interrupta (Curran), the most abundant species, represented 28 and 62% of species the first and the second year respectively. Our research demonstrates that natural biological regulation of the OBLR is the result of a highly diversified parasitoid guild and this should be taken into account in any Integrated Pest Management program.

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).

AbstractThe past 100 yr have seen dramatic philosophical shifts in our approach to controlling or managing pest species. The introduction of integrated pest management in the 1970s resulted in the incorporation of biological and behavioral approaches to preserve ecosystems and reduce reliance on synthetic chemical pesticides. Increased understanding of the local ecosystem, including its structure and the biology of its species, can improve efficacy of integrated pest management strategies. Pest management strategies incorporating insect learning paradigms to control insect pests or to use insects to control other pests can mediate risk to nontarget insects, including pollinators. Although our understanding of insect learning is in its early stages, efforts to integrate insect learning into pest management strategies have been promising. Due to considerable differences in cognitive abilities among insect species, a case-by-case assessment is needed for each potential application of insect learning within a pest management strategy.

The massive use of chemicals in food production process has adversely affected the aspect of cost, ecology and health in particular. Landscape Integrated Pest Management (LIPM) Program is one of the technology applications targeted to minimize the chemicals. In Indonesia, there were only 6 regencies which applied LIPM, which included Banyumas regency. This study primarily aims at comparing production costs, productivity, revenue, profit and financial feasibility between LIPM and non-LIPM rice farms. The researchers collected primary and secondary data during the investigation. They purposively chose Pliken Village as the research object as it is the only village implementing LIPM. Meanwhile, sample was selected by random sampling methods involving LIPM and non- LIPM farmers with 30 respondents for each. Independent-samples T test was exerted to compare productivity, revenue, cost, profit and financial feasibility. The results indicate that productivity, revenue, profit and financial feasibility farming with LIPM were higher than the non-LIPM farming. Moreover, the production cost in the LIPM farming was lower than the production cost of the non-LIPM farming. The independent T-test pinpoints that the total revenue indicator and profit were significant. In other words, it may become reference to encourage farmers to apply Landscape Integrated Pest Management Program for sustainable agriculture

Abstract Urban insect pests such as ants, termites, cockroaches, and bed bugs are more than just nuisances; they often negatively impact structures, landscapes, animal health, commercial food production, food safety, and public health (mental, physical, and financial). Due to the tremendous burden these insects can inflict, researchers, manufacturers, and pest management professionals work to create solutions that effectively manage urban and structural pests. One solution that has proven useful in agriculture is the development of an integrated pest management (IPM) plan; i.e., a science-based approach to pest control that utilizes multiple tactics such as preventative tools, chemical control (sprays, fumigation, and baits), biological control, and exclusion. There are many permutations of urban IPM plans, but in general they consist of five components: 1) identifying the pest, 2) monitoring the pest, 3) developing an intervention plan (including prevention and control techniques), 4) implementing the program, and 5) recording and evaluating the results. The objectives of the current publication were to 1) highlight urban entomology research published in 2019 and 2) show how the results from these publications help pest management professionals create and implement IPM plans.
