| 摘 要： | 蓄齿胫叶甲 Gastrophysa polygoni (Linnaeus)是蓼科杂草蓄上的一种重要天敌昆虫。本文研究了该虫的发育起点温度和有效积温 ,结果表明 ,在 19～ 31℃范围内 ,该虫的发育历期随温度升高而缩短 ,反之则延长。经测定 ,卵的发育起点温度为 (10 .4 5± 0 .14 )℃ ,有效积温为 56 .2 4日度 ;幼虫期的发育起点为 (8.12± 0 .2 4 )℃ ,有效积温为 12 2 .2 0日度 ;蛹的发育起点为 (9.70± 0 .82 )℃ ,有效积温为91.70日度 ;产卵前期的发育起点和有效积温分别是 (16 .17± 0 .96 )℃和 52 .83日度 ;全世代的发育起点为 (12 .6 0± 0 .4 3)℃ ,有效积温为 2 90 .4 0日度

| Abstract: | Gastrophysa polygoni (Linnaeus) is an important natural enemy of Polygonum aviculare Linnaeus.The developmental threshold temperature and the effective accumulated temperature of Gastrophysa polygoni (Linnaeus) were studied.The results showed that the developmental zero of egg was (10 45±0 14)℃,the larva was (8 12±0 24)℃,the pupae stage were (9 70±0 82)℃,the preoviposition period were (16 17±0 96)℃,for the whole generation was (12 6±0 43)℃.The effective accumulated temperature of the egg stage was 56 24 day degree,the larva stage 122 20 day degree,the pupae stage 91 7 day degree,the preoviposition period 52 83 day degree and for the whole generation 290 40 day degree. |
