项目摘要

The mate disruption technic has been applied to the control of tortricid pest for about 20 years in Shizuoka area. This method suppressed the population effectively until several year ago. Recently, remarkable numbers of female were often caught in a monitor traps even in the disruption field. This fact means that resistant populations for disruption were developed in these fields. The experiments were conducted to clarify the evidence and to analyze the mechanism of the resistant trait. We, first, tried to develop a resistant population artificially, because the resistant trait in the field maybe disappeared after stopping the use of disruptant. At the same time, behavioral, electrophysiological, and systematic comparison between the populations from disruption and non-disruption field. We do not find any clear differences in these two populations at this moment. We must continue these analysis because the similar problems must occur in the future.
交配中断技术在静冈地区应用于卷叶蛾的防治已有20年的历史。直到几年前,这种方法才有效地抑制了种群。最近,即使在干扰场,也经常有大量的雌性被捕获在监视器陷阱中。这一事实意味着,在这些领域的破坏抗性群体的发展。本试验旨在阐明抗病性的证据,并分析抗病性的机理。我们首先尝试人工培育抗性群体,因为停止使用干扰剂后,田间抗性性状可能会消失。同时,对干扰和非干扰场的种群进行行为、电生理和系统比较。目前,我们在这两个群体中没有发现任何明显的差异。我们必须继续这些分析,因为类似的问题将来一定会发生。
