为适时防治大青叶蝉,预测其各虫期的发育进度,在自然变温条件下,根据有效积温法则,对该虫的卵、若虫及成虫的有效积温和发育起点温度进行了研究.卵的有效积温和发育起点温度为196.25±10.67日度、8.84±0.94℃;若虫的有效积温和发育起点温度为244.67±28.61日度、14.23±0.80℃;成虫的有效积温和发育起点温度为87.40±14.58日度、19.67±1.19℃.
In order to timely control the leafhopper of Ophiopogon japonicus, the developmental progress of each leafworm period was predicted, and under the condition of natural temperature change, according to the effective accumulated temperature law, the effective accumulated temperature and development start temperature of eggs, nymphs and adults of the worm were studied. The effective accumulated temperature and developmental start temperature were 196.25 ± 10.67 and 8.84 ± 0.94 ℃ respectively. The effective accumulated temperature and developmental start temperature of nymphs were 244.67 ± 28.61 and 14.23 ± 0.80 ℃, respectively. The effective accumulated temperature and developmental start temperature of adults were 87.40 ± 14.58 Day, 19.67 ± 1.19 ℃.
