摘要
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℃.
Tettigoniella viridis L. is a serious pest that infests on the stem of popular.The effective accumulative temperatures and initial temperatures of developmentfor egg, nymph and adult of the pest were measured under the natural temperat-ure condition in Harbin area in 1992 - 1994. The initial temperatures ofdevelopment for egg, nymph and adult were 8. 84 ±0. 94 ℃ 14. 23 ±0. 80℃ and19. 67 ±1. 90℃ respectively. The effective accumulative temperatures for egg,nymph and adult were 192. 25± 10. 67℃ (day-degree), 244. 67 ± 28. 61℃ and87. 40 ± 14. 58℃ respectively.
