Evaluation of the efficacy of different kinds of pheromone traps for the monitoring of Plodia interpunctella Hbn. (Lepidoptera: Pyralidae)

In food industries, different kinds of pheromone traps are used for the monitoring of Plodia interpunctella, but in many cases, it is difficult to relate captured adults with the real density of moth’s population. In this work, the results of laboratory tests of four kinds of pheromone traps have been reported. Three kinds of sticky trap (wing trap, delta trap, strip trap) and a funnel trap have been tested in two Peet & Grady chambers of 28 and 30 m3 with a known number of adults. The wing trap has been tested in three different ways: with only adhesive base, with only adhesive top and with both base and top glued. Captured adults have been counted after 24 and 48 hours. The results are discussed.
