南岭天蚕生态气候适应性及人工养殖技术

在海拔300、400、500、600、700、800、900 m等7个不同高度上建立气象天蚕养饲基地,研究了南岭天蚕的气候适应性。结果表明:南岭天蚕适宜的温度范围为17.0～25.0℃,最适宜温度为22℃,适宜相对湿度60%～70%;最适宜海拔高度在500～800 m之间。南岭天蚕养殖的关键技术如下:3月底4月初日平均温度稳定通过10℃初日后,栎树萌动开苞时即孵化;小蚕(1～3龄)采取人工增温至26～24℃室内养饲;大蚕(4～5龄)以野外大棚或网罩林养为佳。

Climate Adaptability and Artificial Breeding Technology of the Nanling Antheraea yamamai

In order to research the climate adaptability of the Nanling Antheraea yamamai,the breeding bases of Antheraea yamamai were set at seven different altitudes(300,400,500,600,700,800 and 900 m).The results showed that the suitable conditions for breeding Antheraea yamamai were as follows: temperature was between 17.0～25.0℃,and the optimum temperature was 22℃;the suitable relative humidity was between 60%～70%;the optimum altitude was between 500～800 m.The core technologies for breeding Antheraea yamamai were as follows: when the average daily temperature is stable at 10℃ in late March and early April for a day,or when robur germination,incubation of Antheraea yamamai;when yong Antheraea yamamai at instar 1~3,breeding it indoor by artificial increasing temperature to 26～24℃;adult Antheraea yamamai is better to be bred in wild shed or in forest covered by net.
