大庆地区烟蚜发生情况调查

为了解黑龙江烟田烟蚜发生及为害情况,更好的对其进行防治,对黑龙江大庆地区烟蚜越冬情况及烟蚜在烟株上的种群动态进行了调查。结果表明:大庆地区烟蚜生活史属于全周期型,在烟株上烟蚜数量的消长主要呈"单峰常发区",主要以卵在刺玫、李树、杏树等植株的腋芽四周、枝条上的斑痕和枝杈上越冬。4月中旬开始孵化干母,5月上旬有翅蚜开始迁入烟田,7月中旬出现高峰期,8月中下旬有翅蚜开始迁出烟田。通过此次研究可以为黑龙江烟区烟蚜的田间预测预报提供依据,从而可以更好地防治烟蚜的为害。

Investigation on the Occurrence of Myzus persicae in Daqing Area

In order to understand and control the occurrence regularity and injury of Myzus persicae in Hei?longjiang tobacco field,our research group conducted a survey of the hibernation and the population dynam?ics of Myzus persicae on the tobacco plant. It indicated that the life cycle of Myzus persicae in Daqing ar?ea belongs to the full cycle type,and the ebb and flow of Myzus persicae number of tobacco plant mainly showed“unimodal often hair area”,wintering around the axillary bud,branches and spots of branches of da?hurian rose,plum,apricot and other plants. Fundatrix was started to be hatched in April,in early May aphids moved into the tobacco field,the crest-time occurred in middle of July,and in August aphids moved out of the tobacco field. Through this survey,we provide base data for predicting the Myzus persi?cae in Heilongjiang tobacco area,thus injury of Myzus persicae may get a better control.
