Traditionally, olfaction was thought to play a minor role in the behavioral ecology of the sweet potato whitefly, (Gennadius). However, recent research is uncovering significant potential for whitefly management based on olfaction. Incorporating chemical attractants with standard whitefly management programs could significantly improve control. The integration of attractants with biological control is exceptionally promising. Therefore, the behavioral response of and two generalist predators to the green leaf volatiles ()-2-hexenal, ()-3-hexenal, ()-3-hexenyl acetate, and ()-3-hexe-1-ol were investigated in Y-tube olfactometers. Three of the four green leaf volatiles resulted in the attraction of female . Blend optimization indicated a two-chemical blend to be the most attractive blend for female . In addition, this blend was attractive to female (Distant) but did not elicit a behavioral response from either male or female (Horn). The two-chemical blend of green leaf volatiles could be further developed as a lure to attract and its predator, .
传统上，人们认为嗅觉在甘薯粉虱（烟粉虱，Gennadius）的行为生态学中作用不大。然而，最近的研究发现基于嗅觉进行粉虱管理具有巨大潜力。将化学引诱剂纳入标准的粉虱管理方案中可显著提高防治效果。引诱剂与生物防治相结合的前景尤为广阔。因此，在Y型嗅觉仪中研究了烟粉虱及两种多食性捕食者对绿叶挥发物（Z）-2-己烯醛、（E）-3-己烯醛、（Z）-3-己烯基乙酸酯和（E）-3-己烯-1-醇的行为反应。四种绿叶挥发物中的三种吸引了雌性烟粉虱。混合优化表明，两种化学物质的混合物对雌性烟粉虱最具吸引力。此外，这种混合物对雌性温室白粉虱（Distant）有吸引力，但对温室白粉虱（Horn）的雄性或雌性均未引发行为反应。绿叶挥发物的两种化学物质混合物可进一步开发成诱捕烟粉虱及其捕食者温室白粉虱的诱捕剂。
