自然扩散接蚜法规模饲养烟蚜研究

Study on Mass Rearing of Myzus persicae with Natural Diffusion Vaccinating Method

[目的]为规模饲养烟蚜提供技术参考。[方法]以1叶1心期烟苗为试材,利用自然扩散接蚜法进行烟蚜的规模饲养。[结果]1个扩散点接蚜量222.2头/盘,饲养18 d单位面积饲养量可达5.46万头/m2,每千盘接蚜耗时为1.06 h;1个扩散点接蚜量124.2头/盘,饲养20 d单位面积饲养量可达8.18万头/m2,每千盘接蚜耗时为0.96 h;2个扩散点接蚜量67.2头/盘,饲养16 d单位面积饲养量可达6.34万头/m2,每千盘接蚜耗时为3.47 h。[结论]自然扩散接蚜法的接蚜效率高,可作为大规模扩繁烟蚜进行推广。

[ Objective ] To provide technical reference for mass rearing Myzus periscae. [ Method I Natural diffusion vaccinating aphids on seedlings with one slices of true leaf were studied. [ Result ] Setting three treatmemts ： treatment A （ vaccinating 222.2 aphids per plant with 1 diffusing point） , treatment B （ vaccinating 124.2 aphids per plant with 1 diffusing point） , and treatment C （ vaccinating 67.2 aphids per plant with 2 diffusing points）. Results showed that the suitable feeding cycles for treatment A, treatment B, and treatment C were 18, 20 and 16 days after vaccinating, respectively. Within suitable feeding cycles, the feeding quantities for three treatments were 54.6, 81.8, and 63.4 thousands aphids per square meter, respectively. Moreover, natural diffusion method could obviously improve the efficiency of vaccinating a- phids, the consuming time of vaccinating aphids per thousand trays for different treatments were 1.06, 0.96 and 3.47 hours. [ Conclusion ] Natural diffusion vaccinating aphids method is high-efficiency, which can be popularized in mass rearing Myzus periscae process.
