Pine sawflies (Hymenoptera: Diprionidae) are eruptive herbivores found throughout eastern North America. The Diprionidae family, which contains at least 140 species, constitutes the most persistent threat to conifers as population outbreaks can cause widespread defoliation. Because some species are more prone to large, destructive outbreaks than others, species identification is critical to effective management. Although existing taxonomic keys are primarily based on internal adult morphology, substantial variation among species in larval color traits, geographic location, overwintering strategy, host plant, and egg patterns can be diagnostic at the species level. Here, we focus on the Pinaceae-feeding subfamily Diprioninae, of which there are 25 species in eastern North America. We describe the general biology, life cycle, and host-use ecology of Diprioninae, with an emphasis on the variation among these traits within this subfamily. In addition, we provide tools for species identification, including a taxonomic key that utilizes external diagnostic characteristics. Finally, we discuss available management strategies.

Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae), the lesser mealworm, is a ubiquitous generalist pest of poultry broiler and layer facilities, originating in southern Africa and now found worldwide. They spend their full life cycle within the litter and manure of poultry, causing structural damage to poultry houses, injuring birds, and acting as a reservoir for several avian pathogens, notably Salmonella spp. and Escherichia coli. Management commonly consists of spraying walls and floors of poultry houses with organophosphates, pyrethroids, neonicotinoids, or spinosyns between flocks, and periodic removal and replacement of litter. Populations have been observed to become resistant to specific insecticides after ca. 10 yr of consistent use and exhibit cross resistance to insecticides of the same mode of action. Alternative cultural and biological control methods have been identified but are not currently implemented. More research is needed regarding the economic impact of A. diaperinus, the mechanisms of its insecticide resistance, and patterns and mechanisms of colonization for effective integrated pest management programs to be devised and implemented.

In California, the most significant insect pest of almonds and pistachios is the navel orangeworm, Amyelois transitella (Walker) and is a pest of walnuts. This pest attacks the nuts and infestation is associated with aflatoxin contamination. While there are multiple integrated pest management (IPM) practices available, anecdotal evidence suggests that not all tools are equally utilized. To understand current industry practices and barriers to adoption, the authors surveyed tree nut growers and industry professionals across 7 University of California Cooperative Extension meetings in California’s Central Valley. Findings indicate that as managed acres decreased, participants were less likely to report using as many IPM tools, and pest control advisers reported higher use of multiple practices compared to orchard owners and managers. Key barriers to adoption varied by practice and included high economic costs, low labor availability, environmental conditions, and/or timing constraints. Many respondents were skeptical of the efficacy of mating disruption, a relatively new strategy compared to other IPM tools. Finally, a cluster analysis identified thirteen aggregate grower profiles. Groups primarily differed in their use of monitoring practices, although some groups were also less likely to use sanitation or pesticides. Two groups were distinguished as “early adopters” through their use of mating disruption and/or ovibait traps. These findings document variability in adoption of IPM practices for A. transitella in tree nuts. Identification of the primary barriers and constraints for specific grower groups will inform research and extension efforts to further promote adoption of key IPM strategies.

Abstract We investigated the knowledge, attitudes, and practices (KAPs) regarding dengue and its prevention among local residents in all five divisions of Sabah, Malaysia. A cross-sectional questionnaire survey was conducted with 1,000 residents aged 18 years and above. The results revealed that less than one-tenth of the respondents scored high in knowledge (9.6%), while more than half scored high in attitude (64.6%), and less than one-fifth (15.6%) scored high in dengue prevention practices. Economic factors (monthly salary and occupation) were the final independent predictors in all KAP domains. KAP parameters were correlated with each other, but wide gaps between the scores implied that a positive attitude was not translated into either high knowledge or practice scores. Therefore, it is imperative for the authorities to employ multifaceted approaches in future dengue awareness campaigns to increase all KAP domains, especially among those with lower economic status.

Abstract The knowledge, attitudes, and practices (KAP) on the control of mosquitoes and mosquito-borne diseases were investigated in urban informal settlements of Lagos State, Nigeria, during the coronavirus disease 2019 (COVID-19) period. The survey was conducted between December 2021 and March 2022 using a cross-sectional approach in the informal settlements of Bariga, Makoko, and Ajegunle, and in the formal settlement of Ikeja, all in Lagos State. A total of 400 semistructured questionnaires, 100 per community, were administered to consenting adult participants, and the data collected were analyzed using descriptive and inferential statistics. The results showed that of the total respondents, 262 (65.5%) claimed to have previously seen mosquito larvae, while 54.2% of the total were aware that larvae usually develop into adult mosquitoes. Only 167 (41.8%) of the respondents owned insecticide-treated bed nets, out of which 126 (75.4%) slept under such bed nets. The rate of bed net ownership and reasons for not using them were significant in relation to the study communities. The majority of respondents (81.2%) reported using aerosol insecticides almost daily, potentially contributing to the challenge of insecticide resistance in mosquito vectors. Of the mosquito-borne diseases endemic in Nigeria, malaria was the most well-known by respondents (62.7%), followed by yellow fever (13.6%), and lymphatic filariasis (1.5%). These findings highlight the need for both public education on mosquito control and government interventions in urban informal settlements.

Abstract Data from the pest management practices survey conducted annually by the National Agriculture Statistics Service were used to estimate the adoption of integrated pest management (IPM) in California. Surveys indicate 75% or greater use rates by acreage of 11 pest management practices in vegetable crop production in 2022 and 7 pest management practices in fruit and nut crop production in 2021. Agronomic crops have fewer pest management practices used on 75% or more of the acreage, with 4 in cotton in 2019, 6 in rice in 2021, 4 in wheat in 2022, and none in barley in 2019. Scouting for diseases, insects and mites, and weeds is the most widely used pest management practice in all the crops. Differences between use rates measured by acreage and use rates measured by farming operations suggest that large and small operations use different pest management practices. Trends indicate flat to increasing use of many pest management practices in general but decreasing use of some pest management practices in small grain crops. Changes in pest management practices and use rates are influenced by many factors, including University of California IPM efforts, changes in pesticide regulations, changes in crop production practices, and consumer pressures. The information from these surveys will support the development of Extension IPM outreach materials by the University of California Statewide IPM Program.

Systena frontalis (F.) (Coleoptera: Chrysomelidae) is a serious insect pest species of container ornamental plant nurseries, widespread in the central and eastern United States. Adults feeding causes shotholes and skeletonization to the foliage of affected plants, which can reduce aesthetic value, and marketability of the ornamental plants. This paper reviews the biology and current management approaches used against S. frontalis in ornamental plant nurseries in the United States. Information gathered from the cranberry (Vaccinium macrocarpon Ait.) production system is included where they are appropriate and supplementary to the discussion. The paper also discusses the research, extension, and economic questions prioritized by the stakeholders dealing with S. frontalis problems in the container nurseries.

The elm zigzag sawfly (EZS), Aproceros leucopoda Takeuchi, was detected in the United States for the first time in Virginia in 2021. In 2022, it was confirmed in 4 additional states: Pennsylvania, North Carolina, Maryland, and New York. These are the first records of this species in the United States and demonstrate a rapid range expansion of an invasive defoliating pest. Native to Asia, EZS feeds exclusively on Ulmus spp. (elms; Ulmaceae). In the United States, feeding damage ranges in severity from minor to severe. Young instars create a zigzag-shaped pattern in leaves as they feed, while older larvae feed more completely on foliage, leaving only the midvein and sometimes thick lateral veins. This more complete feeding often obscures the signature zigzag defoliation of younger instars. Long-term health impacts to host trees are unknown, though aesthetic damage, growth loss, and branch dieback occur in Europe where it is also invasive. Little is known about management options for this pest, and continued expansion of this species’ range in the United States is expected.
