木薯单爪螨的寄主选择性研究
Preliminary Study on the Host Selectivity of Mononychellus mcgregori (Acari: Tetranychidae)
摘要
Abstract
The effect of the host plants on the development and reproduction of Mononychellus mcgregori were observed via rearing the mites on 5 host plants including Manihot esculenla, Hevea auyanensis, Chaenomeles sinensis, Codiaeum variegatum and Mangifera indica at a constant temperature of 25℃ in the laboratory. The results showed that, host plants had significant effect on the growth and the reproduction of M. mcgregori. M. mcgregori feeding on M. esculenta, H. auyanensisleaves and H. auyanensis leaves could fulfill normal development, and the F0 generation of M. mcgregori feeding on M. esculenta leaves and H. auyanensis leaves was 8.10 d and 8.45 d, respectively, the F, generation was 8.45 and 10.95 d, respectively. But the mites feeding on C. variegatum, C. sinensis and M. indicate could not survive completely and the F0 generation developed only to the larvae period, they was 3.70, 1.80 and 1.60 d, respectively. The offspring-female rate of the mites feeding on M. esculenta leaves was the highest in different host plants, the F0 and F1 was 80.80% and 88.50% ; the second was H. auyanensis, the F0 and F1 was 80.20% and 80:60%. The egg production of a female of M. mcgregori F0 and F1 were all the most on H. auyanensis leaves and they was 25.8 and 29.8 eggs, the mites which was on M. esculenta leaves were the second most numbers and they was 18.6 and 26.2 eggs. There was only F0 generation to lay eggs on C. sinensis, C. variegatum and M. indica leaves, and the egg numbers was 1.2, 0.98 and 0.6, respectively. The average longevity of adults was the longest on H. awyanensis leaves, and the F0 and Ft were 19 and 20 d, the adults that was on M. esculenta were similar to H. auyanensis, the F0 and F1 was 17 and 18 d. compared with M. escidenta and H. auyanensis. The mites only survived in fewer days on C. sinensis, C. variegatum and M. indica leaves, they was 5.5, 5 and 5 d, respectively. The results above suggested that M. mcgregori are most likely to transfer the harm into rubher(Hevea auyanensis). It is a big risk for rubber.关键词
