"Population studies on non-target arthropods were conducted at selected sites during the 1973 Blackheaded Budworm Control Operation on northern Vancouver Island. Three classes of arthropods were monitored. The Insecta, represented by 10 Orders, were the most numerous. A significant reduction in numbers of some Orders of non-target insects was observed shortly after spray application. There was indication that this could be attributed to fenitrothion. Possible long term effects were not investigated"--Abstract, page iii. Arthropoda Effect of insecticides on British Columbia Vancouver Island.
