| Abstract: | Biston suppressaria are the most serious leaf-eating pests in Eucalyptus forests in southern Fujian Province.Control the damage and determine the best control period.By spraying 2%abamectin+Bacillus thuringiensis powder in the forest,compare the early damage of the first generation larvae(May 2)and the mid-term damage(May 13).Result shows that:in the early stage of the first generation of Biston suppressaria larvae,500 g of pesticide per 667 m2was used for prevention and control,and the population reduction rate is 97.5%after five days;the rate of reduction of the insect population is 97.5%in the middle of the damage.For 667 m2,500 g pesticides were applied for control,and the insect population reduction rate is 95.3%after five days;after the damage,1000g pesticides were applied for per 667 m2for control,and the pest population reduction rate is 83.9%after five days,which was significantly lower than the early and mid-term control.In the early and mid-stage of the damage,the second-generation larvae did not cause harm;while the second-generation larvae were still slightly harmed in the later stage of the damage.Prevention and control before the middle of the hazard has a significant effect on improving the control effect and reducing losses,while also reducing the use of pesticides. |
