ABSTRACT
Insect feeding deterrents appear to be one of three groups of compounds from natural sources that have immediate prospects of application for insect pest management; the other two groups are the volatile sexual and aggregating pheromones that already have limited commercial application. The kinds of biologically active substances investigated are as varied as the types of substances elaborated by higher plants, from simple monoterpenes to complex glucosides and alkaloids. The feeding deterrents for insects appear to be a possible alternative, when used alone or as part of an integrated pest management system, to the use of insecticides for control of many insect pests. However, the use of feeding deterrents in all probability will be in conjunction with other methods of control. The information given on the nature of feeding tests, the insect species used, and the effective concentration are very variable in papers.
