Abstract: Insecticides with novel modes of action such as buprofezin, pyriproxyfen, diafenthiuron and acetamiprid for controlling the whitefly (Bemisia tabaci), and benzoylphenyl ureas such as teflubenzuron and chlorfluazuron against lepidopteran pests (especially Spodoptera littoralis), have been introduced in cotton as part of integrated pest management (IPM) and insecticide resistance management (IRM) programs. In order to delay onset of resistance to these insecticides, an IRM strategy has been implemented in cotton fields since 1987. This strategy is focused primarily on controlling B. tabaci and other cotton pests. It incorporates alternative control measures such as mating disruption and the use of novel insecticides with selective properties resulting in encouragement of natural enemies. A rotation scheme was established by which each insecticide is used only once during one pest-generation followed by alternation with another pesticide with a different mode of action. Extensive resistancemonitoring programs were conducted. Base-line bioassays for susceptibility of key pests toward the most important novel insecticides were carried out prior to the resistance monitoring of the field populations. The rational use of insecticides resulted in keeping down the susceptibility of the pests to the various groups of insecticides and in substantially reduced insecticide application. After 10 years of the strategy, a slight to moderate level of resistance to the insect growth regulators (IGRs) buprofezin and pyriproxyfen has been observed in some locations. Adaptations to the changing IGR susceptibility will be taken into consideration by using other, novel insecticides, at locations where resistance problems have arisen. Implementation of a similar IRM strategy in field crops and in ornamental greenhouses has been initiated.
