Pennies for Parasitoids: Savings Add Up When Rearing Wasps on Alternate Hosts

Telenomus remus on Spodoptera frugiperda eggs

By Edward Ricciuti Getting more bang for the buck out of mass production is the Holy Grail for manufacturers, whether they are making automobiles, appliances, or natural enemies that can be used as biological control agents against pest insects.  Sometimes, as research in Brazil suggests, the most cost-effective method requires a little tweaking of what […]

Opportunities and Challenges for Managing Pests in Organic Greenhouses

Screenhouse

By Meredith Swett Walker If you live in a temperate climate, you probably think of greenhouses as a tool to produce fruit, vegetable, and flower crops out of season. But these structures don’t just trap heat; they can also keep pests out. In fact, greenhouses are commonly used in warmer climates but primarily for pest […]

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 […]

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 […]
