With their long lives and extreme reproductive output, social insect queens have escaped the classic trade-off between fecundity lifespan, but evidence for a immunity has been inconclusive. This is in part because pathogenic effects are seldom decoupled from of immune induction. We conducted parallel, blind virus infection experiments laboratory field to interrogate idea honey bee (Apis mellifera) better understand how these ubiquitous stressors affect queen health. found that injected with infectious had smaller ovaries were less likely recommence egg-laying than controls, while UV-inactivated displayed an intermediate phenotype. In field, heavily infected was meaningful predictor whether supersedure cells observed colony. Immune responses receiving live similar inactivated virus, several same proteins negatively associated ovary mass field. work supports hypothesized relationship symptoms failure suggests reproductive-immunity partially, not wholly responsible effects.

Abstract The Western honey bee Apis mellifera is a managed species that provides diverse hive products and contributing to wild plant pollination, as well being critical component of crop pollination systems worldwide. High mortality rates have been reported in different continents attributed factors, including pesticides, pests, diseases, lack floral resources. Furthermore, climate change has identified potential driver negatively impacting pollinators, but it still unclear how could affect populations. In this context, we carried out systematic review synthesize the effects on bees beekeeping activities. A total 90 articles were identified, providing insight into impacts (negative, neutral, positive) beekeeping. Interest change's impact increased last decade, with studies mainly focusing individuals, using empirical experimental approaches, performed at short‐spatial (<10 km) temporal (<5 years) scales. Moreover, environmental analyses based short‐term data (weather) concentrated only few countries. Environmental variables such temperature, precipitation, wind widely studied had generalized negative biological ecological aspects bees. Food reserves, plant‐pollinator networks, mortality, gene expression, metabolism impacted. Knowledge gaps included apiary beekeeper level, limited number predictive perception studies, poor representation large‐spatial mid‐term scales, analysis, understanding pests diseases. Finally, global are an emergent issue. This due their necessity implementing adaptation measures sustain activity under complex scenarios.

Honeybees are the most prevalent insect pollinator species; they pollinate a wide range of crops. Colony collapse disorder (CCD), which is caused by variety biotic and abiotic factors, incurs high economic/ecological loss. Despite extensive research to identify study various ecological stressors such as microbial infections, exposure pesticides, loss habitat, improper beekeeping practices that claimed cause these declines, deep understanding observed losses important insects still missing. have an innate immune system, includes physical barriers cellular humeral responses defend against pathogens parasites.

Abstract Insect-provided pollination services are increasingly threatened due to alarming declines in insect pollinator populations. One of the main threats pollinators and consequently is urbanisation. Here, we investigate effects local habitat quality (patch size, flowering plant richness, bare soil cover, vegetation structure), degree urbanisation (impervious surfaces) 3D connectivity on bee, hoverfly butterfly flower visitors plant-flower visitor networks flower-rich urban dry grasslands. Overall, influenced communities. Although abundance increased with urbanisation, bee species richness decreased increasing impervious surfaces. Flowering ground nesting resource availability were positively related structure boosted visitation rates. In terms plant–pollinator interactions, visited a lower proportion available plants more urbanised areas network modularity specialisation patch size. Our findings show that grasslands valuable habitats for species-rich communities further highlight importance minimizing intensity potential management practices support biodiversity cities.

Because climate change has severely impacted global bee populations by depleting their habitats and food sources, beekeepers must implement management practices to adapt changing climates.
