| Abstract: | We have broadly divided the methods of storage insect manipulation into curative and preventive measures. Sex and aggregation pheromoncs combined with additional sensory stimuli in adhesive bait traps can be utilized as a preventive measure which may lead to insectistasis (a state wherein the insect population density is diminished to the extent of allowing storage without significant impairment). Insectistasis can be readily achieved by continual supervision of store rooms, use of adhesive bait traps in combination with a limited number of curative measures (e.g. gaseous or contact insecticides) timed according to the extent of trap catches. The sensory stimuli causing male storage moths (Phycitinae) to fly towards these bait traps involve, in sequence, a circadian rhythm, increasing or decreasing light (intensity approximately 1–10 Lux), an air current, a vertical rectangular figure and the main pheromone component. The antennae of male Anagasta kuehniella, Ephestia elutella and Plodia interpunctella comprise two types of receptor cells, of which one is selectively responsive to (Z,E)-9,12-tetradecadienyl acetate (TDA) and (Z)-9-tetradecenyl acetate (TA), while the other responds to (Z,E)-9,12-tetradecadien-l-ol (TDO). |
