【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.更多还原
