摘要
利用梨小食心虫性诱剂监测,掌握了梨小食心虫在克拉玛依地区的消长动态,经测定梨小食心虫在克拉玛依地区1年发生4代,越冬代羽化高峰期为4月中、下旬,当年的第1代羽化高峰期为6月上、中旬,第2代羽化高峰期为7月中旬,第3代羽化高峰期为8月上、中旬。通过苹果园、李园和蟠桃园诱蛾效果、蛀果率的比较,表明梨小食心虫更偏食李。
In this article,by utilizing pheromone trapping to attract male moths of oriental fruit moth Grapholitha rnolesta Busck,the growth and decline trends of Grapholitha rnolesta Busck in Karamay were investigated. The result demonstrates that 4 generations of Grapholitha molesta Busck happened in Karamay district every year,the over-wintering generation has a high eclosion middle and the last ten-day period of April,the first generation reaches a high eclosion in the middle and the last ten-day period of June in those years, the second generation reaches a eclosion in the middle ten-day period of July,and the third generation reaches a high eclosion in the first and middle ten-day period of August. It is very important for killing the first generation larva of these two kinds of pests to effectively control the quantity of emergence of these two kinds of pests. By the comparison,in the field experiment,it indicated that Grapholitha rnolesta Busck prefers to eat plum.
