Abstract:

To determine the short-term and long-term effects of wood vinegar on peach aphid, the aphid was treated with 100 times diluted wood vinegar solution on Chinese cabbage, and the reproduction and development data of the peach aphid were measured. The results showed that wood vinegar treatment significantly shortened the reproductive period of peach aphid, and the reproductive period of F1 generation was 37% longer than that of F0 generation. Compared with the control group, the total aphid individuals produced in F0 generation and F1 generation were decreased by 62% and 66%, respectively. The survival rate of F1 and F2 generation in treatment group was 23% and 24% lower than that of control group, but there was no significant difference between F1 and F2 generation. The lifespan of F1 generation was reduced by 25%, while the difference of F2 generation was not significant. This study proved that wood vinegar could shorten the reproduction period, prolong the duration of the nymph aphid, shorten the life span of the peach aphid, and reduce the survival rate of the progeny. In conclusion, wood vinegar has certain inhibitory effect on the growth and reproduction of peach aphid, but this inhibitory effect will gradually weaken with the increase of application frequency, that is, the short-term and long-term effects of wood vinegar are different, so wood vinegar has the development value as a biological pesticide.
