Beetle predatory , preying

There are many other scolytid species that utilize these and similar compounds to effect intraspecific communication. Francke et al. (18) have discovered several spiroketals as active components of scolytid pheromones. Additionally, several parasites and predators utilize the pheromones produced by their scolytid prey as kairomones. For example, the predatory beetle, Temnochlla chlorodla, responds specifically to exo-brevicomin produced by female D. brevlcomls (19). This same phenomenon has been demonstrated recently in Lepidoptera the egg parasite Trlchogramma sp. uses the Hellothls zea (Boddie) sex pheromone to locate the H. zea eggs (20).
