新疆伊犁蔷薇黄卷蛾生物学特性与防治

Biological Characteristics of Yellow Roses Volume Moth and Prevention and Control Technology in Ili Area of Xinjiang

蔷薇黄卷蛾是新疆伊犁河谷林、果园新发生的害虫。2015—2016年采取室内饲养和田间调查对蔷薇黄卷蛾发生为害情况、形态特征、生活史、生物学特性及防治技术进行了研究,以期为防控提供参考依据。结果表明:蔷薇黄卷蛾在新疆伊犁地区1年发生1代,产卵在树缝、老翘皮或树干背面洼裂处,并越冬。在伊宁市和霍城县,翌年3月中旬越冬代卵开始孵化,4月上旬幼虫出现,分散为害,5月上旬开始化蛹,5月中旬成虫出现,6月中旬至翌年3月中旬越冬代卵出现。在尼勒克县,由于气候冷凉,幼虫孵化较霍城县和伊宁市晚逾10d,即4月下旬至5月上中旬幼虫出现,5月中下旬至6月上旬蛹期,5、6月下旬蛹开始羽化成成虫,6月下旬至翌年4月中旬越冬代卵出现。在特克斯县,气候更冷凉,较其他县晚1个月,翌年5月上旬幼虫孵化,5月下旬至6月上、中旬化蛹,6月中下旬至7月上旬成虫出现,7月上旬至翌年4月下旬越冬代卵出现。参试的5种药剂在蔷薇黄卷蛾幼虫时期使用防效均较高,以22%阿立卡(12.6%噻虫嗪+9.4%高效氟氯氰菊酯)微囊悬浮剂3 000倍液效果最佳。

Yellow rose volume moth is a kind of pests in Ili bottom land forest and orchard.Its infestation,morphological characteristics,life cycle,the biological characteristics and prevention and control technology were studied by indoor breeding and field investigation from 2015 to 2016,with a view to provide a basis for prevention and control.The results showed that yellow volume rose moth had one generation one year,and laid their eggs in the trees,old become warped or trunk back depression dehiscence,then lived through winter.In Yining city and Huocheng county,the eggs got eclosion in mid-March of the following year,then became larvae in early April with scattered harm,start pupation in early May,imago in mid-May,overwintering generation eggs came into being from mid-June to next mid-March.In Nilka county,due to a cold climate,larvae hatch more than ten days later than that in the Huocheng county and the Yining city,they appear in late April to late mid-May,and pupation stage in early June,in late May,in late June;pupa began to transform into adult in late June to next mid-April overwintering generation of eggs.Tex county,colder than other county,a month later than other counties,early larvae hatched in May of the following year;pupation in late May to June and in the middle of June;eclosion started in mid-June to early July.Late July early,next generation eggs came into being in early July to late April of following year.The control effect of 5 kinds of reagents used in rose moth larvae period was higher,at 22%,tent card（12.6%thiamethoxam oxazine＋9.4% high fluorine cypermethrin）micro capsule containing 3 000 times liquid effect was the best.
