摘要: 合成了黑翅土白蚁踪迹信息素类似物(Z,Z)-3,6-十二碳二烯醇-1(DDE-OH),该类似物对黑翅土白蚁工蚁具有和信息素提取物类似的行为反应。活性反应阈值为10-3~10 ng/cm,大于10 ng/cm时产生较强的驱避作用。最佳活性浓度DDE-OH与信息素提取物的活性反应之间没有显著差别。

Abstract: A kind of trail pheromone analogue ((Z,Z)dodeca-3,6-dien-1-ol, DDE—OH) of the black-winged subterranean termite, Odontotermes formosanus Sharaki was synthesized. Active concentrations (103-10 ng/cm) of this pheromone elicited similar behavior in worker termites as natural pheromone extract. There was no significant difference between the response of workers to synthetic and natural pheremones (P>0.05). When the concentration of synthetic analogue was higher than 10 ng/cm it had some repellent effect on termite individuals.

Key words: Odontotermes formosanus, pheromone analogue, biological activity
