Interspecies Interaction of Some Click Beetles (Coleoptera, Elateridae)
The interspecies interaction of pheromones of click beetles <i>Agriotes lineatus </i>L., <i>A. sputator </i>L., <i>A. tauricus </i>Heyd., <i>A. ponticus </i>Step., and <i>A. gurgistanus </i>F. was studied using combined pheromone baits containing pheromones of two species. Under field conditions, geranyl butyrate inhibited the attraction of pheromone traps for <i>A. tauricus. </i>The capturing of <i>A. gurgistanus </i>F. males was reduced in the traps containing pheromones of <i>A. lineatus, A. sputator, A. tauricus, </i>and <i>A. ponticus. </i>A positive correlation was found between the application rate of insecticides and the capturing of <i>A. tauricus </i>males in pheromone traps.
