Iris yellow spot virus is bad for onions, but it's good for the thrips species that carry the virus and spread it to onion plants. In a recent study, infected onion thrips lived about 20 percent longer than uninfected thrips, giving them more time to damage onion plants and transmit the virus.
Engineers may recognize the internal muscle structure of a honey bee abdomen for its resemblance to a Stewart platform, a mechanical device that enables six degrees of freedom in movement. Researchers who have found its natural equivalent in bees say the discovery is already informing their work in designing articulating nose cones for rockets.
A new study modeling potential future climate-change scenarios finds the potential for the invasive Japanese beetle to expand its range northward into new regions in North America, though some parts of it southern range could become too warm for it.
Well-known in Lepidoptera and Coleoptera, the distinct black-orange-black color pattern has never been fully documented in Hymenoptera—until now. A study of more than 1 million wasp, bee, and other hymenopteran specimens finds a wide range of variations of the pattern present in 23 families within the order Hymenoptera.
The mosquito species Toxorhynchites rutilus is harmless to humans but is a voracious predator of other mosquitoes. Researchers in Houston, Texas, are hoping the "mosquito assassin" could be put into action as a tool for controlling mosquitoes that carry human pathogens—if they can find an efficient way to raise the predator mosquitoes in the lab.
Yellow mealworms (Tenebrio molitor) have long been produced as fish bait and pet food, but their use as animal feed and even food for people is growing. Researchers are working to fine-tune methods to improve the quantity and quality of mass-reared mealworms.
A new study illustrates how ventral forewing patterns in Bicyclus anynana butterflies are used in sexual communication. Though the patterns are often hidden by hindwings when at rest, the study found the white, UV-reflecting eyespots to be a signal used by females to attract males.
Bumble bee nests can be hard to find and study, so researchers hope they can create artificial nest boxes for them to use and be observed more easily. But will bumble bees use such boxes? New research offers some clues about optimal design and placement of bumble bee "domiciles."
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.
