摘要: 苹褐卷蛾严重危害多种园林花木的嫩芽和叶片,影响其观赏价值和绿化成果,准确预报出各虫态的发生期,是防治该虫成败的关键.经室内多代变温饲养测定结果是:卵期C=14.83±1.38(℃),K=64.11±6.68(DD);幼虫C=15.24±1.41(℃),K=252.58±21.40(DD);蛹期C=15.06±1.01(℃),K=68.94±5.48(DD);全世代C=15.28±3.31(℃),K=382.47±26.92(DD).其结果符合实际发生情况.

Abstract: Pandermis heparana is an insect seriously harmful to the flowers, shrubs and trees in garden. Its larvae feed on their tender buds and leaves, resulting in the decrease of the ornamental value of these plants. In order to control the pest,it is very important to predict accurately on the occurrence of its various growing phases.After raising this insect at varying temperature indoor for more than one generation,the necessary initial development temperature(C) and effective accumulated temperature (K) were found for each phase of its development:egg stage C= 14.83 ±1.38(℃),K=64.11±6.68(DD);larval stage C=15.24±1.41(℃), K=252.58± 21.40 (DD);pupal stage C=15.06±1.01(℃),K=68.94±5.48(DD);a generation C=15.28±3.31(℃), K=382.47±26.92(DD).Based on these parameters,the prediction is quite successful.
