Effect of Solar Radiation Pest Killer on Control of Hyphantria cunea

The American white moth, also known as the autumn caterpillar, belongs to the Lepidoptera and Moth family and is an important garden quarantine pest in the world. Currently distributed in China's Beijing, Liaoning, Shaanxi, Tianjin, Hebei, Shandong and other provinces and cities. The American white moth is highly fertile, spreads rapidly, and has miscellaneous eating habits. It affects more than 200 species of forest trees, fruit trees, crops, vegetables, and weeds. The main hazards are Phalacroles, mulberries, poplars, willows, sorghum, eucalyptus, and purple. Ye Li, Ligustrum, cherry blossoms, cherries, apricots, pomegranates, and some crops, once outbreaks, will cause major losses to forestry and agricultural production. Therefore, the prevention and control of it is very important, but how to prevent and control pollution-free measures still needs to be verified and researched. For insect pests with phototaxis, solar radiation type insecticidal lamps can be used for killing in the prevention and control process.

In the year of outbreak and the central area of ​​the insect source, adults can be caught in the evening, which can play a certain role in reducing the damage of population density; in the year of general occurrence, no special measures are taken to remove the egg mass, which can be found in the process of census and prevention. Eggs removed in time. The solar radiation type insecticidal lamp can well predict the occurrence period and amount of the American moth and effectively control the occurrence of the American moth. The height of 1.5-2.0m solar radiation type insecticidal lamp can be effectively set on all sides of the village where the area is located. Control the occurrence of the American moth.

Through the summary of the installation effect of solar radiation-type insecticidal lamps, we found that the generation of American moths alternates and the occurrence period is not neat. Therefore, it is necessary to flexibly apply various measures to carry out prevention and control, and to achieve four combinations and one insistence in the prevention and control, that is, artificial control. (Mainly the cutting of the net) and the combination of chemical control; the combination of professional team prevention and the prevention of the masses; the combination of blitz prevention and long-term prevention and control, the combination of prevention and control, and the persistence of prevention throughout the occurrence period. As long as we persist in carrying out comprehensive prevention and control, we can certainly achieve the intended goal.
