紫外线辐射对不同虫龄茶尺蠖生长发育的影响
Effect of UV-B on Growth of Ectropis oblqua Larvae
摘要
Abstract
The2ndand5thinstarof EctropisoblqualarvaewereexposedtoUV‐Bfor0,30,60,90,120,or150minto determine the effects of the irradiation on the development time as well as the rates of pupation ,pupa emergence , and deformity of the larvae .The results showed that ,as compared with control , the development for the 2nd instar larvae was significantly delayed ,the abnormal pupation and mortality rates significantly increased ,and the pupation rate ,pupal weight , and emergence rate reduced . On the other hand , the sustained irradiation did not exert significant effect on the growth or development of the 5 instar larvae .Under a same irradiation treatment ,the mortality and pupation rates of the 2nd and 5th instar differed significantly , but the abnormal pupation rate was not significantly different from that of control ,while the eclosion rate of the 2nd instar generally lower than that of the 5th instar counterpart . The eclosion rate of the 2nd instar after being exposed to UV‐B for 150min significantly differed from that of control or the 5th instar larvae .关键词
