| 中文摘要: |
| 茶谷蛾Agriophara rhombata Msyr.是云南茶园一种重要的食叶害虫，属局部爆发性害虫。为明确其生物学特性，准确识别和防控该虫,通过田间调查和室内饲养，对茶谷蛾不同发育期的形态特征和生物学特性进行了系统观测。该虫在云南全年发生4代，在茶树成龄和老叶片上用虫丝和虫粪构筑成虫苞取食。卵散产或卵粒排列成卵块，卵块多为条形或椭圆形；在温度26℃、相对湿度65%条件下，卵期7~10 d，平均9.3 d；幼虫期26~35 d，平均33.1 d；蛹期分别为9~17 d，平均13.9 d；雌成虫发育历期5~11 d，平均8.3 d，雄成虫发育历期1~6 d，平均4.2 d；化蛹时间集中在16∶00-20∶00之间，成虫产卵期可持续1~7 d，成虫羽化高峰为17∶30-20∶30；观察到雌蛾产卵量19~168粒，平均达96.7粒。雌雄蛾触角有明显区别，雌蛾触角为丝状，雄蛾为双栉齿状。研究结果可为茶谷蛾的田间预测和科学防控提供依据。 |
| 英文摘要: |
| Agriophara rhombata Meyr is a kind of leaf eating invasive pests in tea plantation, which belongs to be local outbreaks. In order to clarify its biological characteristics, accurately identify and control it， Via both field observation and indoor rearing, we systematically studied the pest morphological and biological characteristics of the pest in different development stages. A.rhombata occurs four generations a year in Yunnan. It fed on mature or old leaves by using filaments and insect dung to construct insect bracts. Female adults liked laying their eggs on the back of the leaves, single egg on the leaves, but many eggs imbricated together as bar type or elliptic egg mass mostly. Under the condition of the temperature was 26℃ and relative humidity was 65%, and phases of the egg, pupae, larva and adult were of 7~10 days (average of 9.3 days), 26~35 days (average of 33.1 days), 9~17 days (average of 13.9 days) and 5~11 days (♀, average of 8.3 days) / 1~6 days（♂, average of 4.2 days), respectively. The pupation time was between 16∶00 and 20∶00, the oviposition period of adults lasted for 1 to 7 days, and the peak of adult eclosion was 17∶30 to 20∶30. The female moths laid 19~168 eggs, with an average of 96.7 eggs. The antennae of male and female adults were obviously different, the antennae of female adults were filiform in shape, while the antennae of male adults were bispectate in shape. The results can provide a basis for field prediction and scientific prevention and control it. |
