Entomologists can find out a lot about an insect through some simple chemical reactions in a lab. A new review offers a guide to the wide variety of tests, or assays, that can be conducted to measure the fats, sugars, and other compounds in an insect's body—thereby revealing useful clues about how it stores and uses energy.
A new study suggests mosquitoes actually aren't all that good at finding holes in netting, doing so mostly by chance.
Researchers at the USDA-Agricultural Research Service find promising results using clay and silicate dusts to combat lone star ticks. They hope the dusts could be a useful tool against tick species that transmit deadly pathogens to livestock.
New research explores how pupae of certain butterfly species make a "twittering" noise—via a wiggling movement that triggers sound from tiny structures in the membranes between their abdominal segments.
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.
Insects have evolved a variety of mechanisms to try to overcome the effects of insecticides—including, in some cases, help from the bacteria and other microbes living in insects' guts. A growing number of studies indicate a link between symbiotic microbes and insecticide resistance in a diverse range of insects.
A wide variety of insects (such as mosquitoes, shown here) are raised in the laboratory. A new review of research on lab-reared insects shows that they evolve rapidly as they progress through generations raised in artificial environments.
A naturally occurring botanical compound found in anise, fennel, vanilla, and cranberries might be effective in deterring the larval stage of the lone star tick

By Leslie Mertz When a Chinese mantid (Tenodera sinensis) grabs a nice, plump monarch caterpillar (Danaus plexippus), it not only “bites into the fleshy bits” but also eventually gnaws deeply […]
By Leslie Mertz Tortoise beetles are a bizarre group. They look somewhat like tiny turtles with a colorful, or in some species translucent, carapace (the upper shell in turtles), and […]

By Leslie Mertz If an insect ever needed a little love, it would be the immature stage of the drone fly (Eristalis tenax), which is known as a “rat-tailed maggot.” […]
By Leslie Mertz Anyone who has tended a lawn is probably very familiar with white grubs. They are the fat, cream-colored, brown-headed larvae that can grow up to an inch […]
