Abstract

The effects of various concentrations of (9Z,12E)-9,12-tetradecadienyl acetate on the mate-seeking and upwind anemotactic behaviour of the stored-product pest Ephestia cautella were studied in the laboratory in India. The mating rate was inversely related to anemotactic flight at all pheromone concentrations tested. Extensive mating was observed during periods of low flight activity. The pheromone had no effect on calling females. Much anemotactic zigzagging flight activity was recorded 5-15 min after exposure to the pheromone at a rate of 103 ng, while there was little straight flight activity in comparison with zigzagging flight at all pheromone dosages. The highest upwind anemotactic response was observed 5-15 min after exposure to 104 ng of the pheromone. Olfactory studies indicated decreased response to increasing dosages of pheromone.
