A EFFECTIVE ATTRACTION RADIUS: Method for Comparing Species Attractants Determining Densities of Flying Insects

-The catches of bark beetles (Coleoptera: Scolytidae) were compared between attractive traps releasing semiochemicals and passive traps (cylindrical sticky screens hung, at 10 heights of 0.7-11.5 m, on poles). A central attractive-trap pole was surrounded by three passive-trap poles spaced 50 or 100 m away at the apices of an equilateral triangle. The catches of Tomicus piniperda and other scol...

Chemical Ecology of Wood-boring Insects

The roles and chemistry of pheromones that mediate reproductive behaviors of cerambycid beetles have received remarkably little attention, given the economic importance of many cerambycid species. Until recently, very few volatile sex pheromones and nonvolatile contact pheromones had been identified. However, that situation is changing rapidly, with the number of identified pheromones more than...

Chemical Communication in Insects: Background and Application

The ultimate practical goal of pheromone research on insect tsT to place the communication system on a molecular basis and to use the knowledge to detect, survey, trap, or disrupt the population. The ideal procedure is to identify quantitatively all of the components and to use all or some of them as synthesized chemicals in the emitting device in the field. Some of the problems and pitfalls ar...
