A Promising New Parasitoid Drills Down on Emerald Ash Borers
In a recent study, the wasp Spathius galinae successfully established wild populations and outperformed other parasitoids in attacking invasive emerald ash borers in three northeastern states in the U.S. Researchers say it could become a useful biological control agent to protect native ash trees.
New Study Aims to Protect Parasitoids of Spotted-Wing Drosophila
Use of an insecticide can be counterproductive if it also harms natural enemies of a target pest. A new study puts several insecticides currently in use to manage spotted-wing drosophila to the test to see how they do or don't affect parasitoids of the invasive fruit fly.
Balance, Hearing, and More: Why Some Wasps Have Fat Lower Legs
The fat lower legs that dangle below flying wasps in the family Gasteruptiidae turn out to be filled with insect fat body, and they may play key roles in flight dynamics, detecting vibrations from prey, and even detoxification.
In Search for Better Stink Bug Management, Scientists Look Up
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.
Fighting Nature With Nature: Scientists Mobilize Biological Control Against Devastating Fall Armyworm
Researchers at Virginia Tech's Feed the Future Innovation Lab for Integrated Pest Management are looking to biological control for the fall armyworm, with plans to deploy native, mass-reared parasitoid wasps in Kenya, Tanzania, and Ethiopia in the coming year.
Got Aphids? Call in the Reinforcements With Banker Plants
To manage pest infestations in greenhouses, banker plants draw in different insect species that don’t feed on the main crop but do serve as hosts for predator insects that will also attack the pest on the main crop—a useful (and green) tool for integrated pest management.
Another Natural Enemy of Invasive Kudzu Bug Arrives in North America
A wasp species native to Asia was discovered in North America for the first time and shows promise as a potential biological control for kudzu bug.
Pennies for Parasitoids: Savings Add Up When Rearing Wasps on Alternate Hosts
The parasitic wasp Telenomus remus can be cheaper to raise on a commercial scale on the eggs of an alternate host, rather than those of the fall armyworm, the pest the wasp naturally parasitizes in the field
This Wasp’s Larvae Sometimes Grow Hundreds of Soldier Clones—But Why?
Imagine, for a moment, having 3,000 twin sisters. You all live inside a caterpillar, but it’s home, and your numbers serve as a veritable army against any trespassers. Such is […]
Cocooned Wasp Larvae Jump to Find Cool Spots, and to Protect Themselves
The larvae of a parasitoid wasp called Bathyplectes anurus are known to spin cocoons and jump five centimeters while inside of them. Now scientists may have discovered why, according to […]
Laura Timms: 10 Facts about Parasitoid Wasps (Ichneumonidae)
In the past, Entomology Today has featured some posts about parasitoid wasps and how then can be used for biological control of insect pests. For example: – New Parasitoid Wasp […]
277 New Wasp Species Discovered in Costa Rica
Costa Rica reveals astonishing biodiversity of braconid wasps, with 277 new species of the tribe Heterospilini described in the latest special issue of the open access journal ZooKeys. This is […]
Chinese Wasps are Taking on the Emerald Ash Borer
The emerald ash borer (EAB), a relatively new invasive insect pest, has killed tens of millions of ash trees throughout the eastern United States since it was first detected in […]
