温湿度对茶小卷叶蛾生长发育的影响

研究结果表明,茶小卷叶蛾(Adoxophyes orana Fischer von Roslerstamm)卵期发育起点 C=9.57±0.64(℃),有效积温常数 K=110.08±4.29(日度),预测式:N=(110.08±4.29)/(T-(9.57±0.64));幼虫期 C=4.94±2.48(℃),K=450.75±54.70(日度),N=(450.75±54.70)/(T-(4.94±2.48));蛹期 C=8.0±1.15(℃),K=130.83±8.58(日度),N=(130.83±8.

The Effects of Temperature and Humidity on Development of Adoxophyes orana Fischer yon Roslerstamm(Lepidoptera:Tortricidae)

The smaller tea roller,Adoxophyes orana Fischer von Roslerstamm,is thedominant insect pest of tea in China,especially in the regions of middle-lower reachesof Yangtze River.The present paper deals with the effects of temperature and humidity on developmentand distribution of the insect pest.The experimental result shows that the influence of temperature on the speed ofdevelopment accelerated with the rise of temperature within the range of 19-31℃,andthe hatch percentage of eggs increased with the rise of humidity.Some biological constants are found that the egg stage:developmental zero is9.57±0.64℃,and the thermal constant is 110.08±4.29 degree days;the caterpillarstage:the development zero is 4.94±2.48℃,and the thermal constant is 450.75±54.70 degree days;the pupae siage:the development zero is 8.0±1.15℃,and thethermal constant is 130.83±8.58 degree days;the whole generation:the developmentzero is 6.40±1.20℃,and the thermal constant is 720.52±45.42 degree days.
