Wireworm species has been regarded as a
danger for the crops in Kuban region (Southern Russia) for many years.
Over the past years wireworm outbreaks were observed mainly in fields where
high amounts of soil insecticides had been applied to crops in the pre-vious
years. The main click beetle species detected in Kuban region are:
Agriotes
tauricus Heyd., A. gurgistanus Fald. and, usually less harmful, A.
sputator L., A. lineatus L., A. ponticus Step., A. obscurus L., and
Melanotus fusciceps Gyll., whose pheromones have not been completely
studied yet.
The current main objectives of the
research on click beetles in Kuban region are the following:
- synthesis of click beetle pheromones
attracting females;
- designing a new pheromone trap for monitoring
and mass trapping for integrated pest management; these traps not catch
useful insects;
- field optimization of pheromone
baits for Agriotes populations occurring in Kuban region;
- detection of repellent to wireworms
substances derived from tartaric acid to be used as seed dressing;
- creating pheromone analogues for
click beetles. For example thiogeranyl butyrate, trans - geranyl
crotonoate or L - a - alanine geranyl ester, reconstructed forms of a single
pheromone substance of A. gurgistanus Fald. might be added to synthetic
pheromones to obtain synergistic effects and therefore a more effective
tool for mass trapping or mating disruption.
