Hunting cicadas and lugging them back to a nest is hard work for a cicada-killer wasp. But sometimes all that hard work goes to waste, when a fellow wasp swoops in and lays her egg on the other wasp's prey. And that's if the cicada isn't stolen by a bird first.
A new study suggests mosquitoes actually aren't all that good at finding holes in netting, doing so mostly by chance.
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.
Advances in microscopic imaging techniques are revealing, in unprecedented detail, the structure of mycangia—the internal organs that ambrosia beetles use to store and transport the symbiotic fungi they farm.
Researchers in Pakistan evaluated the factors that influence venom production in scorpions, with the aim to maximize venom extraction for research and medical uses.
With high-speed, high-definition cameras, researchers at the University of Arizona got an unprecedented look at the mating habits of the solitary bee species Diadasia rinconis and gained new insights into their courtship behaviors and the selective pressures those behaviors produce.
A new study that explores the effect of smoke on honey bee (Apis mellifera) behavior finds that it reduces the instance of bees releasing a venom droplet in their signaling of danger to other bees, which researchers speculate may thereby reduce the amount of alarm pheromone released.
In the course of a study on mosquito movement, researchers discovered that local colonies of honey bees had foraged on a nontoxic sugar bait meant for the mosquitoes. The bait was dyed red to track mosquitoes that fed on it, but the dye also showed up in much of the bees' honey.
A new study shows that harlequin bugs can adapt their pigmentation (or melanin levels) during their developmental stages based on outside temperatures. Such thermal melanism enhances the pest species' potential to invade new regions and environments.
Ever wondered how one might feed 20 million fly larvae every week? Get a glimpse into the work of entomologists who fine-tune the diet for mass-reared screwworm flies at the Panama – United States Commission for the Eradication and Prevention of Screwworm.
A new study published in the Journal of Insect Science outlines a new technique that quickly, simply, and inexpensively marks bees to track their movement—and it's non-lethal, too. It could make for an valuable improvement for mark-and-recapture methods for these pollinators.
The invasive spotted lanternfly often lays its eggs on tree limbs and trunks. A new study finds that putting infested wood through a wood chipper effectively destroys spotted lanternfly egg masses, and researchers recommend the practice for reducing the potential spread of the pest.
Males of the butterfly species Mimeresia neavei feature blue, structurally colored wings, the only species in the Mimacraeina subtribe to do so. Researchers in Hungary credit M. neavei's blue wings to a form of coloration found in several butterfly groups but not experimentally examined within Lycaenidae.
Entomologists at the Great Lakes Forestry Centre in Canada have crafted a standardized naming convention for their laboratory insect stocks, and they suggest other similar facilities could adopt the naming format, as well.
Insect and arthropod specimens set in clear resin are a valuable tool for teaching entomology both in the classroom and in public outreach. A team at Texas A&M University has developed an efficient, cost-effective process for resin casting and shares the instructions with the entomological community.
In a new study at the University of Arizona, researchers used body-mounted cameras to evaluate the efficiency of two insect pest sampling techniques—a sweepnet and a vacuum—in a cotton field. The perspective offered new insights into how such methods can be evaluated and could help growers and integrated pest management professionals further fine-tune their sampling techniques.
