Response of the red palm weevil Rhynchophorus ferrugineus to its aggregation pheromone under laboratory conditions
Bulletin of Insectology 62 (2), 257-260
Abstract: Behavioural responses of insects to semiochemicals may be affected by physiological status. The effect of different dosages of aggregation pheromone at 1, 10, 100 and 1000 ng/1 µl hexane on the diurnal responses of virgin and mated male and female Rhynchophorus ferrugineus (Olivier) (Coleoptera Dryophthoridae) was studied under laboratory conditions, using a two-choice pitfall static olfactometer. Pheromone concentration, as well as sex and mating status, was found to affect the behavioural responses of the weevils. In both sexes the response to ferrugineol increases with mating. Based on the results, due to searching behaviour of mated females to find the new oviposition sites, they showed stronger response to aggregation pheromone than the unmated ones.
