The American white moth is a quarantine pest of the whole country. It feeds on the leaf meat with larvae. It is eaten by nature and has bulimia. It can eat the leaves of the whole tree within a few days. Adults mostly spawn on the back of the host tree canopy near the edge of the dorsal, larvae hatch after a short period of time, cluster feeding. The net screen can be as long as 1.5 meters, the larvae live longer in the screen, and they are dispersed after the fifth instar. The second and second instar larvae only eat leafy meat on the back of the leaf, and the damaged leaf is in the form of a "roof window". The third instar larvae can eat the leaves into small holes. The fourth and fifth instar larvae start to bite from the leaf margin, resulting in edge nicks and sixty-seven instar larvae. The whole leaf is often eaten together with the main vein, leaving only the petiole. A generation of larvae began to damage in mid-May, second-generation larvae occurred in mid-July, and third-generation larvae began to damage from early September to mid-November. The worm prefers to live in a sunny and warm place. Therefore, they are mostly distributed in the parks, orchards, courtyards and trees along the streets. There are many methods to control American moths. From the whole growing period, we can take measures to strengthen phytosanitary measures; artificial physical control measures include artificial cutting net screens, grass trapping, digging and exterminating, light trapping and other measures; biological control adopt release week. Coleoptera, using the American moth sex pheromone lure and other measures. In view of the current characteristics of the American moth outbreak, chemical prevention and control should be carried out. Before the American white moth did not break the net, spray the diflubenzuron III 1000-1500 times solution, or the 52.25% chlorpyrifos high-chlorine emulsifiable concentrate 2000 times, or the 1.2% matrine emulsifiable concentrate 1000-2000 times solution on the canopy. However, due to the influence of the American white moth net screen, the liquid is difficult to contact with the body, and the control effect is not ideal. Therefore, when spraying the above-mentioned pesticides, be sure to add special penetrants for organic silicones imported from the United States—exhibited thoroughly. Generally, add 5-10 ml of exhibition per 15 kilograms of liquid medicine, and the control effect will be above 98%.
