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.
In a new special collection on trap and cover crops in integrated pest management, experts review the latest research on various habitat-management methods and their applications in both deterring pest populations and fostering natural enemies of crop pests.
The fall armyworm's impact on maize earns plenty of attention, but it is in fact polyphagous. Sorghum, a key cereal crop in Africa, is also vulnerable to the pest's damage, and researchers are working on biocontrol and other integrated pest management methods in hopes of containing the fall armyworm's impact around the world.
A new study shows that growing a variety of crops in the same field increases local insect diversity and even improves the ratio of natural-enemy insects to pest insects.
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
While a greenhouse structure affords growers pest control options that are not available for field crops, such as physical exclusion, it can also create challenges.
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 […]
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 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 […]
Since 2007, the U.S. Department of Agriculture has been directing studies of a tiny Asian wasp called Trissolcus japonicus. These wasps are parasitoids of the brown marmorated stink bug (Halyomorpha […]
Wasps in the genus Trichogramma are tiny beneficial wasps that feed on the eggs of several insect pests. To help rice farmers in the Greater Mekong Region, a project was […]
The spotted lady beetle (Coleomegilla maculata) preys on aphids, spider mites, and other plant-damaging pests, making it a possible biocontrol agent — an organism that is used to control pest […]
A new book called Good Garden Bugs: Everything You Need to Know about Beneficial Predatory Insects by Dr. Mary Gardiner, an entomologist at Ohio State University, offers gardeners an easy-to-follow […]
By Chris Patrick Imagine combating stink bugs with … stink bugs. Halyomorpha halys, the brown marmorated stink bug (BMSB), is a notorious, non-native agricultural pest — an indiscriminate destroyer of […]
The lettuce aphid (Nasonovia ribisnigri) is an important pest of lettuce worldwide. Lettuce growers have traditionally used chemicals to control the aphids, but even that can be difficult since the […]
Entomology researchers in the University of Kentucky College of Agriculture, Food and Environment have received encouraging results in their fight to protect Kentucky ash trees from the emerald ash borer […]
