Study shows there is no difference in pollination success between part-night lighting and full darkness, highlighting the ecological benefit of switching off our street lights even for short periods in the night.
Declines in native bee populations are widely reported, but can existing data really analyze these trends? Utah State University and USDA entomologists Meiners, Griswold and Messinger Carril report findings about pollinator biodiversity in California's Pinnacle National Park derived from three separate surveys spanning 17 years and say similar studies in other areas are needed.
Fruit flies fed antibiotics to supress their gut microbiome are forced to avoid the best food patches if they lack vital amino acids, according to a study by Boaz Yuval from The Hebrew University of Jerusalem in Israel and Chang-Ying Nui from Huazhong Agricultural University in China, publishing Jan. 16, 2019, in the open-access journal PLOS ONE.
Ozaena ground beetles likely have anatomical adaptations enabling them to parasitize ant nests throughout their life cycle, according to a study published Jan. 16, 2019, in the open-access journal PLOS ONE by Wendy Moore from the University of Arizona, USA, and colleagues.
Among the many threats to honey bee colonies around the world, one stands alone: the parasitic mite, Varroa destructor. For decades, researchers assumed that varroa mites feed on blood, like many of their mite and tick cousins. But new University of Maryland-led research suggests that varroa mites have a voracious appetite for a honey bee organ called the fat body, which serves many of the same vital functions carried out by the human liver.
As whole-roasted crickets gain traction as a protein-rich snack and restaurants experiment with mealworms on the menu, there's still 'an overwhelming lack of knowledge' concerning the ecological sustainability of the emerging, multi-million-dollar insects-as-food industry, say researchers at the Swedish University of Agricultural Sciences. In an opinion article published Jan. 14 in the journal Trends in Ecology & Evolution, they explore unanswered questions around insect rearing, safety, and environmental impacts.
Insects and mammals have special sensors for different light intensities. These sensors selectively influence the circadian clocks and thereby control daily activity patterns.
In a new study published in the open-access journal PLOS Biology on Jan. 10, Sunitha Narasimha, Roshan Vijendravarma and colleagues report how fruit flies (Drosophila melanogaster), which lay eggs communally, use chemical deception to protect their eggs from being cannibalized by their own larvae.
For the first time, a group led by Denise Aumer and Eckart Stolle, at the Martin-Luther-Universität Halle-Wittenberg's Institute of Biology, have finally found the root cause responsible for thelytoky syndrome--which dramatically turns bees from altruistic helpers to selfish mercenaries.
Using the CRISPR gene editing tool, researchers have developed a new way to control and suppress populations of insects, potentially including those that ravage agricultural crops and transmit deadly diseases. The 'precision-guided sterile insect technique' alters key genes that control insect sex determination and fertility. When pgSIT eggs are introduced into targeted populations, only adult sterile males emerge, resulting in a novel, environmentally friendly and relatively low-cost method of controlling pest populations in the future.
