Abstract:

Developing means to reduce the population of phytophagus species of insects by applying synthetic sex pheromones requires deep investigation on the sexual behavior of the target insect. Determination of sexual behavior peculiarities of the target insect species is one of the key tasks of screening methodology and application of synthetic sex pheromone systems in the integrated crop protection. Finding all links in the chain of the target insect’s sexual behavior is complex because it requires the development of certain methodological procedures, specific to each case. For these reasons, the determination of sexual behavior of some species of insects with hidden life mode (M. brassicae, E. schreineri), is of particular interest both theoretically and practically. During the investigations, attention was paid to such species as the information obtained can be applied in the process of deciphering the mechanism of action of synthetic sex pheromones on each gender separately. It was shown that females of the E. shreineri species bear pheromone glands and males respond to this pheromone only in cases where females demonstrate their calling position. Most elements of sexual behavior are similar to those found in the M. brassicae species, but some characteristics are only relevant to the corresponding species.
