As pests go, spotted wing drosophila (SWD) is a relatively new one in mainland North America. While it was well known in Hawaii, SWD was first discovered in mainland North America in California in 2008. A year later it was found in the Pacific Northwest in Washington, Oregon and British Columbia. It has moved east since then, to Florida, the Carolinas, Michigan and other states.

Botanical oils – those made from plant essential oils such as rosemary and mint, have a place in a whitefly program because of the unique benefits they offer. Dr. Murray Isman, Professor of Entomology/Toxicology at The University of British Columbia, lists these benefits as multiple modes of action, short residual activity, less toxicity to bees, zero preharvest interval (PHI),...
