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

The release of tiny insects to combat an invasive weed is paying off, according to a recent study by the U.S. Department of Agriculture. Scientists from the USDA’s Agricultural Research […]
By Andrew Porterfield A new study from the University of Minnesota has found that the selective insecticide sulfoxaflor is just as effective at controlling soybean aphids (Aphis glycines) as broad-spectrum […]
A host-specific parasitoid wasp from Russia -- Spathius galinae -- has been approved for release to help control the invasive emerald ash borer
By Alexandre Diniz, José Roberto Postali Parra, and Aloisio Coelho Jr. Some biological control programs involve large-scale rearing of millions insect predators that are released near agricultural crops. In Brazil, […]
By Ed Ricciuti Scientists working on environmentally friendly ways to combat insect pests continually quest for biological control’s version of a better mousetrap: natural enemies of a harmful species that […]
By Dr. Rob Morrison Research recently appearing in the journal Biological Control may change how we view native predators of the brown marmorated stink bug (BMSB). BMSB is an invasive […]
