A study examining monarch butterflies' preferences for laying eggs on milkweed in cropland, open ground, or prairie—as well as predation rates on eggs in those settings—offers some mixed signals for monarch-conservation efforts.
A simple change in the choice of grass varieties for lawns of St. Augustinegrass could be a key tool for fending off fall armyworm infestations, according to new research. While no single St. Augustinegrass cultivar rises above the rest in resisting infestation, mixing varieties may confer some benefits, as fall armyworms clearly preferred single-cultivar plantings in a series of lab tests.
Honey bees are in high demand for pollinating crops, and hives are often trucked thousands of miles a year to serve different crops in different regions and seasons. But researchers say honey bees show signs of stress from all that travel.
When pesticides show up in the pollen that honey bees collect, can the source plant be pinpointed? A new study is the first to successfully combine chemical analysis of pollen and the keen eye of a palynologist—an expert in identifying pollen microscopically—to track pesticide in bee-collected pollen to a source plant genus.
New research on bacterial endosymbionts in insects suggests that such bacteria may infect a wide variety of insect species but a low proportion of individuals within those species.
A new collection of reports in Environmental Entomology highlights the need for pesticide risk assessments that account for the differing qualities and behaviors between honey bees and bumble bees, solitary bees, and stingless bees.
Honey bees are incapable of buzz pollination, but they can (and do) perform pollination duties in highbush blueberry. A new study shows that, while honey bees rarely collect blueberry pollen in the pollen baskets on their hind legs, they frequently contact it with other body parts and transfer it to other flowers.
Researchers now know the temperature range in which the annual bluegrass weevil is most active, thanks to a set of tools first adopted for underwater photography.
Cotton and corn are threatened by growing resistance in the pest Helicoverpa zea (a.k.a. bollworm or corn earworm) to the insecticidal properties of Bt crops. Two researchers identify contributing factors and identify insecticide resistance management practices that could help slow the problem.
New research on brown marmorated stink bug behavior indicates they prefer darker surfaces, doorways, and the north and east sides of homes—and that insecticide-treated netting offers potential as a means of nuisance control.
In the Brazilian savanna, the larvae of a fruit-fly species exploits an ant-plant mutualism by trapping and preying on ants atop the plant's nectar deposits.
A review of existing research on floral resource competition between managed honey bees and wild bees shows gaps in our knowledge about such interactions and calls for further research to better inform decisions on honey bee management and pollinator protection.
Solitary bees face different—and less well-understood—challenges from pesticide exposure than their colony-dwelling honey bee cousins. A pair of entomologists encourage colleagues to dedicate more research to these important pollinators.
After a 100-year flood struck south central Oklahoma in 2015, a study of the insects, arthropods, and other invertebrates in the area revealed striking declines of most invertebrates in the local ecosystem, a result that researchers say illustrates the hidden impacts of natural disasters.
Queens of bumble bee Bombus impatiens that encounter imidacloprid in their spring foraging period delay nest initiation and brood emergence
Should growers that use Bt crops plant a separate nearby refuge field of non-insecticidal crops, or use a blended mixture of seeds that produce both in the same field?
