Technical Abstract: Research activities are addressing questions on chemical longevity of the lures, and the release rates and ratios of the synthetic attractants. New analytical methods were developed using Fourier transform infrared (FTIR) spectroscopy to quantify ammonia from lures. Other lines of research include using electroantennogram (EAG), a technique that measures response of antennal olfactory receptors to volatile chemicals. Although the technology has been available for decades, EAG typically has been used as a screening tool to confirm biological activity of candidate compounds. Recent improvements in quantification of chemoreceptive responses provide a new framework for comparative evaluation of potential attractants and a basis for determination of how antennal receptivity is affected by insect physiological state (e.g. sex, age, reproductive status). Spatial analysis of trapping data is being used to evaluate insect movement and trapping efficacy, and evaluation of bait station formulations is ongoing.
