Technical Abstract: Orientation of flying insects to pheromone in a closed, warehouse environment is not as efficient as that in a field environment where wind direction and plume intermittency provide additional cues about the location of a pheromone source. The effects of adsorption and re-emission of pheromone from nearby surfaces also are relatively more important in a storage than in a field environment. In this report, the alterations in searching behavior that result from such constraints are considered by three dimensional analysis of searching behavior flights by male Cadra cautella (Lepidoptera: Pyralidae). The shape of the plume around a pheromone-emitting female is inferred from comparisons with published descriptions of flights in a wind tunnel.
