In Nepal, the gall-inducing eupatorium gall fly (Procecidochares utilis) is deployed as a biological control agent against the invasive weed Ageratina adenophora. A new study by researchers at Tribhuvan University and the Feed the Future Innovation Lab for Integrated Pest Management shows size and abundance of galls induced by the fly are influenced by elevation, knowledge that can help in fine-tuning P. utilis-based biocontrol efforts.
A new report in the Journal of Integrated Pest Management shares the successes and lessons learned from an advanced biological control-based IPM program that is helping rice growers in China, Laos, and Myanmar manage pests in more environmentally and economically sustainable ways.
A recent study shows that male emerald ash borers infected with a deadly fungus readily transmit the fungus when mating, opening doors for future biological control efforts.
A new report in the Journal of Integrated Pest Management shows that a beetle species released into the wild as a natural enemy of the invasive hemlock woolly adelgid appears to be successfully establishing in urban environments in addition to forest settings.
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.
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.
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.
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.
The story of "Team Trissolcus," insect taxonomists who sprang into action to identify the parasitoid wasps that might help us fight the invasive brown marmorated stink bug.
Meet Rebecca Schmidt-Jeffris, Ph.D., assistant professor at Clemson University, expert in biological control in fruit crops, a big fan of mites, and the subject of the next installment of our "Standout Early Career Professionals" series.
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.
A survey of mosquitoes in Pennsylvania discovered 12 mosquitoes parasitized by larval mites. Water mites can reduce the survival and reproductive success of mosquitoes, and entomologists are investigating such parasitism to evaluate its potential as a method for biological control efforts.
When a foreign parasitoid wasp was introduced to North America to control invasive pea aphids, it outcompeted most native wasps, except for one: Praon pequodorum. Its secret weapon: a resistance to pea aphids' natural defenses.
A recent study in Oregon details the predatory habits of the wasp Astata unicolor—its preferred prey is the invasive brown marmorated stink bug—and notes its potential as a native natural enemy of the invasive pest.
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.
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.
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
