Summary: This project has 3 phases. Phase I. Establish and maintain a colony of SWD in Parlier, CA with the throughput necessary to routinely conduct fumigation studies. Phase II. Determine the mortality of phosphine as well as several key phosphine mixtures to eggs, larvae, pupae and adults of SWD in 1ft3 chambers at 35`F. Report dose-mortality regressions with statistical validity to establish most tolerant SWD life stage. Phase III. Optimize phosphine and its mixtures to control the most tolerant SWD lifestage as quickly as possible at 35 `F. With intent of decreasing stand-alone fumigation requirements, the effect of hydro-cooling on SWD mortality will be evaluated and integrated with fumigation data to be reflective of mortality expected from entire “packing system”.
