Verification and Evaluation of Male-Produced Pheromone Components from the Citrus Long-Horned Beetle, (Forster) (Insecta: Coleoptera: Cerambycidae).

The citrus long-horned beetle, (Coleoptera: Cerambycidae), is a highly polyphagous species native to eastern and southeastern Asia. Detection of these beetles is dependent on visual surveys, which are inefficient and labor-intensive. The identification and development of pheromone-based lures would help improve survey efforts for should it become established within the US.

Direct competition and potential displacement involving managed Trogoderma stored product pests.

The establishment of an exotic pest may require displacing local species with a similar niche. The potential of Trogoderma granarium to displace Trogoderma inclusum was explored in a stored product setting. We performed direct competition experiments varying commodity and temperature over different durations.

Electrophysiologically Determined Spectral Responses in Lobesia botrana (Lepidoptera: Tortricidae).

Electrophysiological methods were used to test the visual sensitivity of European grapevine moth, Lobesia botrana (Lepidoptera: Tortricidae) to wavelengths ranging from 300 to 700 nm. For male and females tested, a main, peak response occurred in the 460-540 nm range (blue-green wavelengths) with females having a generally lower response to wavelengths in that range. A second smaller peak was observed for both sexes at the 340-420 nm range.
