Abstract The pear psyllids (Cacopsylla Ossiannilsson; Hemiptera: Psylloidea: Psyllidae) are a taxonomically difficult group of at least 24 species native to the Palaearctic region. One or more species occur in most pear-growing regions, in some cases as invasive introductions. Existing reviews of this group are primarily of taxonomic focus with limited overviews of biology. The earliest biological studies of the pear psyllids centered on a core group of a few western European species. In part, this focus arose because diversity of the pear psyllids was poorly understood. As taxonomic understanding has advanced over the last 3 decades, research has expanded taxonomically. Increasing difficulties in controlling the pear psyllids additionally has contributed to growth in research. Here, we review a now-extensive literature on diversity, biology, and management of the pear psyllids. Three broad observations emerged from this synthesis. First, large gaps in biological understanding of the pear psyllids persist for several geographic faunas, most notably for psyllids of the Eastern Palaearctic region. Second, taxonomic diversity is accompanied by biological diversity. Despite the commonality in host use among the pear psyllids, with each species being limited to development on Pyrus, striking differences exist among species in life cycles, wintering, and other biological traits. Third, many of the tools being used to manage pear psyllids today are in existence because of the long history of basic research which has targeted these pests. These tools include new insecticides of higher selectivity, various cultural and horticultural tactics, and practices that conserve natural enemies in orchards.

Abstract The bamboo grasshopper, Ceracris kiangsu Tsai, is a serious pest of bamboo in China and Southeast Asia, and it overwinters as eggs for a period of up to 9 mo. Despite its importance, cold tolerance has not been thoroughly examined in this species. Thus, the present study investigated the low-temperature tolerance of overwintering eggs collected in the field, particularly the effects of rapid cold-hardening (RCH) and cold acclimation (ACC) on egg survival, and changes in the cryoprotectant contents. The supercooling point of overwintering eggs collected from the field was −23.9 °C, and their survival rate after exposure to −22 °C for 6 h was 26.6%, thereby suggesting that the cold tolerance strategy employed by C. kiangsu is freeze avoidance. After exposure to 0 and 4 °C for 12 and 24 h, or 0, 4, and 8 °C for 5 days, the survival rate of eggs subjected to −22 °C increased to approximately 50%, with significant effects of RCH and ACC. The glycerol levels in RCH and ACC treated eggs were also significantly higher than those in the control group, but the protein and trehalose contents were either reduced or not significantly altered. These results indicate that glycerol functions as a low molecular weight cryoprotectant in C. kiangsu eggs, and that RCH and ACC treatment facilitate its accumulation, thereby enhancing cold tolerance. Furthermore, the correlation between RCH and ACC was investigated.

Abstract Nitrogen fixation is often cited as an important nitrogen source for termites. However, the rate of nitrogen fixation between experiments and termite species is highly variable due to termite diversity and sampling limitations. New evidence suggests that subterranean termites (Coptotermes formosanus Shiraki) (Blattodea, Rhinotermitidae) seek alternative dietary nitrogen sources for colony growth and development. This study compares N2 fixation rates and nitrogenase gene expression rates to a diverse assemblage of feeding groups. It was observed that nitrogenase expression was much higher in one-piece nesting termites from the family Kalotermitidae which lack access to soil. On the other hand, subterranean termites from the family Rhinotermitidae fix nitrogen at much lower rates, not differing from ambient nitrogenase activity in soil.

Abstract Both science festivals and insect festivals have increased in frequency in the last few decades. In order to compare insect festivals with science festivals, we modified a validated science festival visitor survey (EvalFest) for Purdue’s Bug Bowl, a long-running insect festival. Benchmarking against EvalFest and Collaboration for Ongoing Visitor Experience Studies (COVES) results, we found that Bug Bowl audiences were similar in having high levels of education, a high interest in science, and frequently visiting science venues. In fact, 23% of Bug Bowl survey takers indicated that they were actual scientists themselves. In contrast to EvalFest results, Bug Bowl had a higher rate of returning visitors than new visitors. Bug Bowl visitor motivations were primarily to have fun and bring their children for a learning experience, and they rated their experiences very positively. Ninety-one percent of Bug Bowl attendees surveyed lived in the state of Indiana. We discuss gaps in expected visitor demographics and possible applications for a shared common evaluation within a working group of insect festivals.

Abstract Over the past 2 decades, digital photography has grown increasingly accessible. This has ushered in a golden age of community science, where nonspecialists share natural history observations from across the globe via digital media. Importantly, these observations are accessible to researchers, who can readily share expertise directly with the community and connect observations and observers with research projects. This has fueled a rising number of publications combining specialist and nonspecialist observations, which occasionally make national and international headlines. Entomology has embraced this trend, but the scope and impact are not clear. A review of its effect on the field is therefore warranted. Herein, we review and analyze publications that incorporated information from photographs shared on photo-sharing websites. In total, 2,123 publications that incorporated information from 77 photo-sharing websites were examined. Seven websites accounted for 66% of the publication citations. 84.6% of publications focused on data from the Holarctic ecoregion (56.2% Palearctic and 28.4% Nearctic). Forty-six arthropod orders were represented, but the Big Five—Lepidoptera, Coleoptera, Hymenoptera, Hemiptera, and Diptera—accounted for 75% of all publications. We divide the publications into 28 discovery and use categories, review how community photograph data has been used within each category, and provide examples of categories utilized in nonentomology natural history fields, which we hope will provide inspiration and spur future research. We also discuss benefits and considerations when using such data—including the accuracy of identifications, inherent biases, and digital data impermanence—and suggest best practices to follow.

Pollinator nutrition is a highly complex subject that we are just starting to unravel, from the multidimensional nature of bee forage (pollen and nectar) to how the abiotic environment can affect the resources available to bees. Doing so is of utmost importance, as improving pollinator resource availability and nutrition is one of the proposed mechanisms to improve populations and pollinator health. However, landscape change has changed the resources naturally available for pollinators. Farmland and cropping systems create a unique nutritional landscape for pollinators, with agroecosystems typically containing few crops dominating a landscape along with natural corridors containing noncrop plants. The types of crops planted and the surrounding landscape will ultimately affect the nutritional landscape bees have access to. Even the management practices in agriculture and how pests are controlled will, directly and indirectly, affect bee health and nutrition. Hence, a better understanding of bee nutrition in agricultural ecosystems is warranted. This review synthesizes research on bee nutritional ecology and the agricultural landscapes to advance our understanding of bee health in agriculture. Graphical Abstract

Cactus species are well represented in arid and semiarid environments, where they sometimes even dominate the landscape, forming true cactus forests. In this review, we summarize for the first time the importance of cactus species as a wood resource for a neglected saproxylic (dead wood-dependent) entomofauna associated with decomposing and decomposed tissues in arid and semiarid environments. The complex decomposition process of cactus species is discussed in depth. We provide a checklist of the entomofauna living in decaying and decayed cacti, in which insects represented 93% of the species recorded. In particular, Coleoptera (41.5%) and Diptera (43.8%) orders together represented 85% of the insect species recorded. The family Drosophilidae made up 50% of studied Diptera species because the drosophilid–cactus–yeast complex has been widely studied during recent decades. However, we found that during the last 2 decades, there has been increasing interest in investigating the diversity of arthropods in this saproxylic habitat in Mexico, with a special focus on Syrphidae (Diptera) and Coleoptera, the former for their role in the decomposition process. Disentangling the role of the insects associated with decaying cactus is a challenge when it comes to understanding the function of xeric saprophagous insects in this environment. One frontier in this research area is to find whether decomposed stems in xeric soils would act as “islands” of fertility due to the amount of nitrogen which could be recuperated from these microecosystems. Further research is needed to understand the ecological succession of the entomofauna playing a role in the decomposition process of cactus species in semiarid environments. Graphical Abstract

Stink bug (Hemiptera: Pentatomidae) development typically requires feeding on a diversity of plant species and various plant tissues. During feeding, stink bugs discharge salivary enzymes with roles in extraoral digestion and countering plant defense responses. Although previous research has described digestive salivary proteins from stink bugs, less is known of the salivary proteins involved in the suppression of plant defenses. We sequenced the transcriptomes of salivary glands dissected from five stink bug species collected from non-crop habitats in Washington: Halyomorpha halys (Stål), Nezara viridula L., Euschistus conspersus (Uhler), Thyanta pallidovirens (Stål), and Chlorochroa ligata (Say). We identified a total of 677 candidate secreted proteins from the salivary glands of the five species. Based on work from other insects, many of the proteins have potential functions in the suppression of plant defense signaling and deactivation of plant defense molecules. We also identified salivary proteins with potential roles in the extraoral digestion of plant tissues, protection from entomopathogens, and deposition of salivary sheaths. This report provides a curation of putative salivary effector genes for further functional analysis.
