Production of field corn in the southeastern United States is often impacted by a number of insect pests. However, surveys to assess stakeholder perception of the relative importance of insect pests and adopted management decisions for these pests have not been extensively reported in the region. A survey was conducted in North and South Carolina to address deficiencies in our knowledge about how corn producers perceive insect pests, implement management and insect resistance strategies, and understand and implement integrated pest management (IPM). The survey indicated that stink bugs (Hemiptera: Pentatomidae) and corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), were the most commonly managed insect pests in field corn. For transgenic corn expressing insecticidal toxins from Bacillus thuringiensis (Bt) (Berliner), the rate of resistance management (i.e., planting of non-Bt corn refuge) implemented (59%) by growers was higher than previously reported. The majority of grower respondents identified ear development as the most critical corn growth stage for managing stink bugs (52%), with the most commonly reported management strategy being applications of insecticide at the economic threshold. Growers also reported understanding the concepts of IPM and implementing it in field corn. Assessing the adoption of preventative approaches, such as Bt corn and insecticide seed treatments, and strategies to manage insect resistance, in the case of Bt corn in particular, is critical for tailoring research and Extension efforts to protect the durability of these management tactics.

Mango (Mangifera indica L.) is an important source of food and income in Kenya, but production is hampered by the proliferation of invasive fruit flies (Bactrocera dorsalis). The International Centre of Insect Physiology and Ecology (icipe) and its partners have over the past 2 decades developed and disseminated an integrated pest management (IPM) package of interventions that effectively reduce fruit fly populations, but adoption is relatively low. In response to this low adoption, the authors conducted desk- and field-based qualitative and quantitative studies to better understand the gendered barriers and opportunities for scaling IPM practices along the mango value chain in Kenya. Twenty-four gender-disaggregated focus groups, 118 farmer surveys, and 63 key informant interviews with value chain actors were conducted. The results show that lack of access to IPM inputs, market constraints, and access to training are among the key barriers to and motivations for adopting IPM strategies in Embu County, Kenya.

Agricultural production and crop yields are threatened around the world by the emergence and spread of agronomical pests, including diseases, insects, and weeds. Due to changes in precipitation, carbon dioxide levels, and warming temperatures being experienced throughout most of the world, new challenges are emerging for pest management in virtually all major cropping systems. While precise environmental impacts due to climate change are impossible to predict, they will require innovative and new solutions for pest management. In this article, we explore the challenges of 3 problem pest species with soybean: Johnsongrass, kudzu bug, and charcoal rot. Understanding pest responses to climate change is vital for better understanding the new agricultural innovations that will be required to manage them in the future.

Currently, there are a total of 15 thrips species in the genus Megalurothrips (Thysanoptera: Thripidae). Megalurothrips sjostedti Trybom and Megalurothrips usitatus (Bagnall) are the most economically important pest species because of the serious damage they can do to leguminous crops, especially cowpea, which is an important grain crop for Africa and a vegetable crop for the rest of the world. Megalurothrips sjostedti is only distributed in Africa, while M. usitatus is widely spread in subtropical and tropical regions of the world and is more invasive. Nigeria is the only area where both thrips species are shared. Inexplicably, M. usitatus does not seriously damage cowpea in Africa. Bioecological characteristics indicated that M. usitatus adapts to a wider temperature and humidity range, which may result in its current geographic distribution. Since the 2010s, M. usitatus has received more attention and research. The integrated pest management (IPM) strategy of both thrips as case studies was reviewed in this paper, along with multiple complementary tactics, including agronomic measures, physical-chemical lure control, biological control, and chemical control, and insecticide resistance. Lessons have been learned from both M. sjostedti and M. usitatus, as well as from another widespread invasive thrips species, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), thus enhancing our overall understanding of the biology, ecology, and IPM practices of M. sjostedti and M. usitatus.
目前，大尿蓟马属共有15种(蓟翅目:Thripidae)。大尿蓟马和大尿蓟马(Bagnall)是经济上最重要的害虫，因为它们可以对豆科作物，特别是豇豆造成严重损害，豇豆是非洲重要的粮食作物和世界其他地区的蔬菜作物。大尾蓟马仅分布于非洲，而大尾蓟马在世界亚热带和热带地区广泛分布，具有较强的入侵性。尼日利亚是唯一一个两种蓟马共有的地区。令人费解的是，M. usitatus对非洲豇豆的危害并不严重。生物生态学特征表明，紫杉适应较宽的温度和湿度范围，这可能是其目前地理分布的原因。自2010年代以来，M. usitatus得到了更多的关注和研究。以这两种蓟马为例，综述了其综合防治策略，并结合农艺措施、物化诱防、生物防、化学防、抗虫等多种辅助策略。本文从sjostedti和M. usitatus以及另一种广泛存在的入侵蓟马物种Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae)中吸取了经验教训，从而提高了我们对M. sjostedti和M. usitatus的生物学、生态学和IPM实践的整体认识。

Adventive populations of Trissolcus japonicus (Ashmead) have been detected in the eastern and western United States including the western states of Washington, Oregon, California, and Utah. These populations may provide classical biological control for the invasive brown marmorated stink bug, Halyomorpha halys (Stål), which can cause economic loss to many specialty crops in western North America. Idaho has not previously been surveyed for the exotic T. japonicus or native parasitoids of H. halys. In July 2021, T. japonicus was discovered emerging from wild H. halys egg masses in Star, Idaho (43.69788, −116.49427), and was detected on yellow sticky cards from July to September. This is the first record of T. japonicus in the state of Idaho. T. japonicus constituted only a small portion of Trissolcus species detected; other species included T. euschisti (Ashmead), T. hullensis (Harrington), and T. utahensis (Ashmead). Genetic population level analysis of T. japonicus specimens from Idaho supports the likelihood of its expansion inland from the west coast, inhabiting ecozones previously considered unsuitable due to high temperatures and low humidity. This report opens the prospect of an effective biological control agent for H. halys in Idaho and potentially other hot and dry geographic regions and expands documentation of the presence of adventive T. japonicus populations in North America.

Hibiscus mealybug, Nipaecoccus viridis (Newstead), is an invasive, highly polyphagous pest that has recently established in Florida. This pest is historically known to heavily effect citrus production in other citrus-producing regions and has similarly negatively impacted citrus groves in several counties. Hibiscus mealybug was first found infesting citrus in one county in 2019 and has rapidly spread across counties and onto additional hosts in only a few years. Here we review the known distribution and biology of hibiscus mealybug, including a description of life stages, known host plants in Florida, and management options. Additionally, a field diagnostics guide is presented to assist in early detection and prevent the spread of N. viridis in other regions. We anticipate that information shared here will help in slowing its spread in the United States.

Survival of North American species of ash (Oleaceae: Fraxinus spp. L.) is threatened by emerald ash borer (EAB), Agrilus planipennis (Fairmaire), a phloem-feeding beetle that destroys the vascular system of its host. In forested sites where ash is a dominant overstory species, mortality caused by EAB can substantially alter conditions, with potentially cascading effects on ecosystems. In urban forests, ash trees were often abundant and provided an array of ecosystem services because of their rapid growth, capacity to withstand stressful urban conditions and prior to EAB, low pest load. Annualized costs of managing EAB on urban ash trees over the next 30 yr in the United States has been estimated to approach $1.8 billion. Numerous cost-benefit analyses have demonstrated that it is more cost effective to retain mature ash trees with systemic insecticides than to replace these trees in urban areas. Effective protection of urban ash trees depends on deployment of systemic insecticides before EAB injury disrupts the vascular system that transports insecticide to the canopy. Given the ongoing spread of EAB, timely management is critical for protecting urban ash canopies. Over the last 2 decades, we have encountered persistent myths that have hindered the adoption of protective measures to preserve urban ash in communities recently infested by EAB. Here we review these myths and counter them with research-based evidence that supports and justifies an ash management program. Finally, we use the 5 basic tenets of IPM to outline an approach for managing EAB in urban forests.

Late-season lepidopteran defoliators in the genera Anisota, Dryocampa, Datana, and Lochmaeus are usually considered minor pests which primarily cause aesthetic damage on hardwood trees in managed and natural areas. While foliage loss late in the season does not typically impact tree health, severe defoliation can occur on individual branches or entire trees, causing great concern to homeowners and land managers. We review the distribution, biology, damage, and management of several native late-season hardwood defoliators in the southeastern United States, including oakworms, mapleworms, yellownecked caterpillars, and variable oakleaf caterpillars. Affected hardwood trees typically leaf out the following spring even after severe defoliation. While management is seldom recommended due to timing or amount of damage, it may be warranted in certain situations. We provide management recommendations for these late-season defoliators, including chemical and nonchemical options for homeowners and land managers.

The genus Anoplophora (Coleoptera: Cerambycidae) is among the most well-known insect genera in invasive entomology and is represented by 2 noted invasive alien species: the Asian longhorned beetle (Anoplophora glabripennis (Motschulsky, 1854)) and the Citrus longhorned beetle (Anoplophora chinensis (Forster, 1771)). In this study, a new non-native species belonging to the genus Anoplophora, Anoplophora horsfieldii (Hope, 1843), has been discovered on Jeju Island, South Korea (33°30′N, 126°30′E). Our field survey of the established area and potential habitats nearby identified numerous adult beetles and exit holes in its host, Celtis sinensis Persoon, 1805. This finding emphasizes the importance of continued monitoring and management of this new non-native species, which has the potential to cause significant ecological and economic damage.
