摘要
为适时防治云杉小黑天牛(Monochamus sutor L.)提供科学依据,在模拟自然条件下,对该虫的卵、蛹的有效积温、发育起点温度,成虫和初孵幼虫的发生期测报进行了研究。云杉小黑天牛蛹的有效积温为114日度,发育起点温度为9.0℃;卵的有效积温为66.9日度,发育起点温度为11.5℃。利用历期法、有效积温法对成虫、初孵幼虫发生期予测,其结果与实际调查基本相等。
To provide a scientific basis for the control of the spruce beetle (Monochamus sutor L.) timely, we studied the effective accumulated temperature and the initial temperature of pupa and eggs in a simulated natural condition. The prediction of the occurrence of the beetle and newborn larva was studied, too. Results are as the following:(1) the effective accumulated temperature for pupa is 114 day-degree and the initial temperature for development is 9℃; (2) the effective accumulated temperature for eggs is 66.9 day-degree and the initial temperature for the development is 11.5℃. The prediction date for occurrence of the adult and that of newborn larva using effective accumulated temperature and calender method agree with that of actual occurrence.
