2005,2006年对枇杷潜蛾(Lyonetia eriobotryae)的生物学特性进行了研究,结果发现其在云南终年发生,全年的高峰发生期在7~10月,冬季发育缓慢但不越冬;枇杷潜蛾天黑后开始产卵,雌成虫用产卵器刺破新梢嫩叶下表皮将卵产于叶肉及表皮之间,卵单产,2~4 d后开始孵化并在叶肉内取食,从梢尖到木质部较为坚硬的部分都是其蛀食范围,老熟幼虫出梢后吐丝下垂在叶片下作“H”型茧化蛹;在15~30℃条件下卵、幼虫、蛹、成虫的发育历期分别为2~4 d,17~26 d,5~12 d,3~10 d,完成1代需要27~52 d。药剂实验表明90%杀虫丹、20%灭扫利对枇杷潜蛾具有很高的防效,开始施药适期为4~5月。比较全面的研究了枇杷潜蛾的生物学特性,并给出了在当地比较可行的防治方案。
The biological characteristics of Lyonetia eriobotryae in 2005 and 2006 were studied. The results showed that it occurred all year round in Yunnan. The annual peaked from July to October, while the winter developed slowly but not overwintered. After dark, spawning begins, and the female adult pierces the lower epidermis of the shoot with the ovipositor. The eggs are produced between the mesophyll and the epidermis. After 2 to 4 days, the eggs begin to hatch and feed on the mesophyll. The harder part of the xylem is its eaten range. The larvae of mature larvae sap under the leaves for “H” type cocoon pupation; the eggs, larvae, pupae, The developmental stages of adults range from 2 to 4 days, from 17 to 26 days, from 5 to 12 days and from 3 to 10 days, respectively. It takes 27 to 52 days to complete the first generation. Pharmacy experiments show that 90% insecticidal Dan, 20% of sweeping Lee on the loquat moth has a very high control effect, began to apply the appropriate period of 4 to May. A more comprehensive study of the biological characteristics of the loquat moth, and gives a more feasible local control programs.
