摘要
本文就2013年在内蒙古赤峰市荞麦田突然大量发生的西伯利亚龟象的生活史及习性、危害特点以及田间化学药剂防治效果进行了研究。结果显示:西伯利亚龟象以成虫在土壤表层越冬,第二年5月下旬出土危害,6月中、下旬交配产卵直到9月上、中旬。幼虫蛀茎危害,成虫取食叶片、嫩茎和嫩梢,并能作短距离飞行。田间药效试验结果显示:喷施高效氯氰菊酯+噻虫嗪拌种,施用两周后对西伯利亚龟象的防效可达95%,八周后防效高达98%,喷施高效氯氰菊酯、辛硫磷,以及辛硫磷+噻虫嗪拌种也会显著提高防治效果。
In the present research,the life cycle and biological characteristics of Rhinoncus sibiricus Faust broke our on the buckwheat cultivation in Chifeng of Inner Mongolia in the 2013 year were investigated,meanwhile,the damaged characteristics and chemical control test were studied in two years. In the study of life cycle investigation,it was revealed that adults over winter in the surface soil and come up out of the ground in the late May of the next year,mate and lay eggs from the mid- to- end of April to the early-to- mid September,larvae bore and damage the buckwheat stem,adults can feed young stem,leaf and migrate in short distance.Chemical control tests exhibited that the effects of spraying beta- cypermethrin and thiamethoxam mixed with seeds were high to95%,98% after treatment for two and eight weeks respectively,and spraying beta- cypermethrin,phoxim and thiamethoxam mixed with seeds can significantly improve control effects.
