We discuss the potential pros and cons of using importation biological control against the soybean aphid, Aphis glycines Matsumura (Homoptera: Aphididae). Importation of exotic organisms for biological control is never completely risk-free, but the potential negative impacts of not achieving biological control of invasive pests may exceed the risks associated with a biological control introduct...

Surface arthropods on pome fruits can cause export problems and disrupt commercial markets. Eliminating insects and mites on the packing line would be the last opportunity to provide for pest-free produce. In this study, an experimental packing line was used to evaluate techniques using different surfactant baths, pressurized water sprays, and styles of rotating brushes to remove field-collecte...

Development of alternative methods for pest management is needed with the increased concern for adverse effects of pesticides for human health and the environment. The main goal of our study was to test the oil from seeds of sugar apple (Annona squamosa), an edible tropical fruit for pest control. The oil pressed out of seeds was as effective in controlling the silverleaf whitefly, Bemisia arge...

Populations of hemlock woolly adelgid, Adelges tsugae Annand (Homoptera: Adelgidae), in the northeastern United States are injurious and unregulated, and fluctuate greatly in response to various abiotic and biotic factors. Because the life stages of A. tsugae are sedentary and firmly attached to hemlock twigs throughout most of the year, they are unable to escape the deleterious effects of weat...
