| Research Abstract |
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.
