| 中文摘要: |
| 室内饲养观察结果表明,甘薯天蛾各虫态的发育起点温度分别为卵15.1℃、幼虫14.5℃、预蛹14.4℃、蛹16.8℃、成虫11.7℃;有效积温分别为卵40.8日度、幼虫158.3日度、预蛹37.6日度、蛹123.9日度、成虫58.7日度;全世代的发育起点温度为15.6℃,有效积温为370.6日度。根据有效积温法则推算,该虫在泰安一年发生3～4个世代,与田间调查结果和发生规律相符。 |

| Under laboratory condition,the developmental thresholds of Herse convolvuli(Linnaeus) for eggs,larvae prepupae,pupae,and adults were determined as 15.1℃,14.5℃,14.4℃,16.8℃ and 11.7℃,respectively,while their effective accumulated temperatures were 40.8 day degrees,158.3 day degrees,37.6 day degrees,123.9 day degrees and 58.7day degrees,respectively.The yearly generation number of this insect pest inferred by effective accumulated temperature was 3-4 generations in Tai'an region,which was coincident with its actual occurrence records. |
