Summary: The relationship between bee community composition and habitat characteristics at local scales is important for management and conservation. Ecotones can support diverse bee communities by providing complementary habitat characteristics. In a forest-shrubland ecotone, floral abundance negatively affected bee richness and functional diversity, while trees and coarse woody debris had a positive association with bee diversity. Soil composition and functional richness were also associated with bee diversity.

Summary: Declines in bee populations, in part due to pesticides, especially insecticides, are of global concern. Few studies have focused on non-Apis solitary bees, which are considered essential pollinators in the field. This study analyzed insecticide residues in Osmia cornifrons bees and their environment, finding that insecticides applied in orchards were detected at high frequency and even in orchards without a known history of insecticide application, various insecticides were detected.

Summary: In recent years, there has been a growing interest in insect husbandry to meet the demand for raw materials production, food supply, and biological/environmental control. However, large insect rearings are vulnerable to infections from pathogens, pests, and parasitoids. This study presents an automated counting method using computed tomography, which allows for quick and efficient monitoring of insect populations in rearing systems.

Summary: The study found that the dominance of honey bees is significantly and negatively associated with wild bee diversity, regardless of local management practices. Semi-natural habitats have a positive impact on functional diversity of wild bees, while urbanization and crop cover around orchards have no effect on diversity metrics. In locations with high honey bee dominance, a greater number of bee species exhibit less common combinations of functional traits, especially larger bee species with longer tongues.

Summary: Bees play a crucial role in pollinating crops and wild plants, but are facing decline due to factors like habitat loss, food scarcity, climate change, and pressures from pests and pathogens. Efforts are being made to restore habitats, improve pest management practices, detect threats to native bees, and monitor populations to protect vulnerable species. Collaboration is key in addressing these challenges and maximizing resources for bee conservation efforts.

Summary: This article examines the diverse approaches to pollinator protection within the pesticide regulatory environments of the United States, the European Union, and selected Asian countries. The US adopts a reactive approach, while the EU embraces a proactive stance. Some Asian countries face challenges with inadequate regulations, leading to adverse health and environmental consequences.

Summary: In hybrid sunflower, the contribution of bees to productivity may be over or underestimated. To accurately estimate bee effects on seed traits, exclosures with specific porosity sizes are recommended. The use of exclosures with porosities of about 3 to 5 mm can prevent over or underestimation of bee effects. Holistic insect management in sunflower cropping systems is also recommended to balance the benefits of bee effects with pest insect control.

Summary: To locate honey bee hosts, parasitic Varroa destructor mites rely on tactile and chemosensory cues. Altering these cues in the honey bee colony environment may help manage Varroa destructor mite populations. Through experiments, we found that chemical compounds detected in honey bee colonies or extracted from honey bees and mites affected Varroa destructor's locomotion behavior. The mites appear to use multiple cues to navigate within a colony environment.

Summary: Secondary metabolites produced in glandular trichomes of tomato, specifically mono- and sesquiterpenes, have contrasting roles in interactions with the potato aphid Macrosiphum euphorbiae. While sesquiterpenes derived from TPS12 contribute to host plant resistance against M. euphorbiae, monoterpenes derived from TPS20 appear to be exploited as cues for aphid orientation towards host plants.

Summary: The study developed a spatially targeted biocontrol strategy using a drone to detect Persicaria perfoliata and release Rhinoncomimus latipes. The aerial images taken at <= 15 m above the ground successfully detected the weed patches, allowing for the successful escape of over 98% of the released insects. The use of a rotary-wing UAS for aerial detection and deployment of biocontrol agents in hard-to-access areas was effective.

Summary: Glossy buckthorn (Frangula alnus) is an invasive shrub from Europe that has been threatening native vegetation in North America. This study found that glossy buckthorn exhibited spatial aggregation and resided beyond forest roads. The density and presence of glossy buckthorn decreased as the distance from the forest road increased, suggesting the potential for precision management by targeting specific areas where it is present.
