Scientists Use Insects to Control an Invasive Weed

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 Service released arundo gall wasps (Tetramesa romana) and arundo scale insects (Rhizaspidiotus donacis) several years ago as part of a biocontrol program to kill a […]

Sulfoxaflor Found to Be Less Harmful to Beneficial Predators of Soybean Aphids

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 insecticides, without causing significant harm to some beneficial predators of the aphid. The new study by Anh Tran, Tavvs Alves, and Robert Koch, published in […]

USDA to Release Russian Wasps Against the Emerald Ash Borer

With the emerald ash borer beetle devastating ash tree populations throughout the United States, solutions to help fight the insect are critical. Thanks in part to research from the University of Delaware and the USDA’s Agricultural Research Service, a host-specific parasitoid wasp from Russia — Spathius galinae — has been approved for release to help […]

Biological Control in Brazil is Used on an Area that is Larger than Belgium

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, researchers have implemented of a number of successful biological control programs. Brazil is the world’s largest producer of sugarcane, which has one of the oldest […]

A New Parasitoid Wasp from Russia May Help the Fight Against Emerald Ash Borer

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 outperform those already employed against it. In the case of invasive pests, the hunt may take scientists far afield, even to remote corners of the […]
