METHOD OF ATTRACTING MALE HESSIAN FLIES

摘要

Male Hessian flies (Mayetiola destructor) are attracted and trapped by use of a fly trap charged with an effective amount of the sexual pheromone (2S)-(E)-10-tridecen-2-yl acetate, or a racemic mixture containing the same, and males and females are disrupted from finding mates at higher dosages. The pheromone is advantageously used at a level of up to about 500 mu g in the fly trap method, more preferably at a level of from about 10-100 mu g. The charged fly trap may be placed in proximity to a wheat field for monitoring and control of the Hessian fly. Mating between male and female Hessian flies is disrupted by release of amounts of (2S)-(E)-10-tridecen-2-yl acetate (or a racemic mixture containing the same) from a number of points throughout a region populated by Hessian flies at a rate of between 1 and 1000 mg/hectare/hour.
