New technology for mating disruption and prospects for integration with SIT: Exosex{sup TM} and Exolure{sup TM}

Abstract

Full text: The Exosex autoconfusion system has been successfully trialed against a variety of insect pests and is now registered for use in certain countries. It differs fundamentally from all other mating disruption systems by contaminating the target pest with electrostatically charged powder formulated with pheromone or other biologically active materials. The method requires only 25 dispensers and less than 100 mg of pheromone per hectare. The mode of action in disrupting mate location, courtship, and mating, may include a variety of effects, all of which contribute to the efficacy of management of the pest in question. The most important are believed to be the following: - False trail following: - Habituation; - Trail masking; - Sensory imbalance; - Inhibition of courtship; - Enhancement of predation and; - Delay of mating. Factors making Exosex autoconfusion such a uniquely powerful technology are demonstrated by the following calculations based on the threshold responsiveness of Cydia pomonella to pheromone. One particle of Entostat{sup TM} (wax) powder contains on average 67 femtograms (6.7 x 10 14 g) of formulated pheromone, and there are approximately 1.5 x 1010 particles per gram of powder. One particle resting on the antennae would theoretically release sufficient pheromone to  More>>

One particle of Entostat{sup TM} (wax) powder contains on average 67 femtograms (6.7 x 10 14 g) of formulated pheromone, and there are approximately 1.5 x 1010 particles per gram of powder. One particle resting on the antennae would theoretically release sufficient pheromone to induce habituation of responsiveness to pheromone. Approximately 1,800 particles would constitute an attractive source for a male moth in the field. Hence the contents of one Exosex dispenser are theoretically capable of contaminating around 1 billion male codling moths with enough pheromone to make them attractive sources to other males. The Exosect technology has also given rise to a highly efficient lure and kill method, in which slow-acting chemical insecticides or entomopathogens can be spread throughout a pest population by autodissemination. Both the mating disruption and lure and kill technologies are clearly compatible with SIT, and several new ideas will be presented concerning ways of combining the technology to increase the efficiency of SIT and reduce the costs of area-wide treatments.
