A parasitoid wasp from Asia offers promise for biological control of the brown marmorated stink bug in North America, but new research suggests that monitoring efforts using primarily ground-level traps may be looking in the wrong place.
Research in Pennsylvania shows that overall colony weight and the number of worker bees to be the leading factors in determining overwintering survival of honey bee (Apis mellifera) colonies. For colonies in which the combined weight of adult bees, brood, and food stores exceeded 30 kilograms, overwinter survival rates were about 94 percent.
Tiny beetles once known as tea shot hole borers are actually a group of four distinct species that appear almost exactly the same to even the trained eye. In a new study, researchers combine both physical measurements and molecular genetics to better define the members of the Euwallacea fornicatus cryptic species complex.
The invasive Asian longhorned tick could find plenty of suitable habitat in North America that is similar to its native region, according to new research from the Rutgers University Center for Vector Biology.
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.
A new study suggests mosquitoes actually aren't all that good at finding holes in netting, doing so mostly by chance.
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.
When honey bees produce more propolis, a waxy resin they use for sealing up their hives, overall health benefits to the colony ensue. A new study tests a few simple methods beekeepers can use to encourage more propolis production in their hives.
A new study shows that growing a variety of crops in the same field increases local insect diversity and even improves the ratio of natural-enemy insects to pest insects.
Several emerging mosquito-management methods require the transport of mosquitoes to precise locations. There, lab-reared mosquitoes—for instance, sterilized males—mix with wild mosquitoes and hinder the population's ability to reproduce or transmit disease. But, getting mosquitoes from lab to wild presents logistical challenges. A team led by researchers at New Mexico State University are tackling this problem and have made a surprising discovery about just how tightly live mosquitoes can be packed up.
Researchers in China say a protein bait derived from leftover brewer's yeast attracted more spotted-wing drosophila flies than existing attractants in a lab test.
Despite headlines to the contrary in British tabloids this fall, harlequin ladybird beetles are not killing off native species by giving them a sexually transmitted fungal infection. "There have been stories mixing up various research findings into quite sensational headlines, which is a shame because these fungi and the ladybirds are fascinating in their own right," says ecological entomologist Helen Roy, Ph.D., of the Centre for Ecology & Hydrology in Wallingford, England.
Subterranean termite colonies can be as large as 1 million individuals with a foraging territory and underground galleries stretching up to 100 meters long. How does an entomologist study something that large? Here's a behind-the-scenes look at how researchers at the University of Florida have raised entire termite colonies from scratch and devised experimental setups that mimic large foraging and nesting areas while still fitting inside a lab.
Learning how cuckoo bumble bees cheat the eusocial system can tell scientists a lot about how insect sociality evolves and how hosts and parasites coevolve. But, as other bees face declines, cuckoo bees will only get more difficult to study.
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.
