Polyiodide salts of acridine orange were isolated from solutions of an acridine and I2 in methylene chloride, ethanol, and acetone. The products from all solutions were found to contain both amorphous and crystalline material. The isolated crystallin

The temporal development of biological control of arthropod pests in perennial cropping systems is largely unreported. In this study, the development of biological control of twospotted spider mite, Tetranychus urticae Koch, and hop aphid, Phorodon h

The grape mealybug, Pseudococcus maritimus (Ehrhorn), is the dominant mealybug in Washington's Concord grape vineyards (Vitis labrusca L.). It is a direct pest of fruit clusters and a vector of grapevine leafroll-associated viruses. Using traps baite
