Well-Fed, Older Asian Longhorned Beetles Fly Farther, May Require New Quarantine Zones

Asian longhorned beetle

By Andrew Porterfield The Asian longhorned beetle (Anoplophora glabripennis) has been an invasive pest in North America since 1996, when it arrived from China and Korea, probably through infested wood-packing material.

Setting a Baseline: A Clearer View of Mosquito Resistance to Insecticides

Culex pipiens

By Andrew Porterfield Mosquito control professionals have made significant gains toward managing malaria worldwide, as well as defending against West Nile virus, chikungunya, dengue, St. Louis encephalitis, and, more recently, Zika. However, mosquito resistance to existing insecticides also has been making gains. According to the World Health Organization, 60 countries have reported some mosquito resistance […]

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 […]

Beneficial Beetle Diversity Blooms on Strip-Tilled Farms

By Andrew Porterfield Biodiversity of insects has become an important issue in agriculture. Large-scale, intensive agricultural practices involve mechanically tilling the soil, managing pests with chemicals, and the use of plastic mulches and covers. While these practices control pests and increase crop yields, they can also reduce the populations of beneficial insects. Organic and conventional […]

Treating Southern Soybeans with Neonicotinoids Yields Economic Benefits After All

By Andrew Porterfield The class of insecticides called neonicotinoids (neonics) were introduced to a lot of fanfare from farmers and environmentalists alike. They were seen as far less toxic than alternative pesticides, and could be applied into the soil or on seeds, avoiding the damage to beneficial insects that’s often caused by sprays. But recently, […]
