The number of army insects in autumn has increased sharply since September! The prevention and inspection bureau said that since September, the main planting period of hard corn in China has entered. Recently, the number of adults trapped in Yunjia area has increased significantly, and a number of pest reports have been received in Yunlin area. Farmers are called on to strengthen inspection and control, intensive field inspection, grasp the early planting period of the best occurrence of insect pests, early detection and notification, and immediate use of drugs (organic fields can be sprayed with thiobacillus). Combined with physical prevention and control, such as removing eggs and worms, the harm can be avoided and the epidemic situation can be effectively controlled.

After Chiayi City completed the last jigsaw puzzle of the autumn military and insect epidemic at the end of August, it was officially declared that the whole of Taiwan had fallen, and since September coincided with the second phase of hard corn planting in the country, the number of pest reports showed a rapid growth trend.

Chen Hongbo, head of the plant epidemic prevention team of the Bureau of Prevention and Quarantine, said that the number of reports of autumn military insects had slowed down since August, but since mid-September, in the monitoring statistics of sex pheromones set up in producing areas and victimized field areas, it was found that the number of male adults trapped in Yunlin and Chiayi areas increased significantly, and there was also a sharp increase in reported cases of larvae. Therefore, it is speculated that a new generation of adult Eclosion has appeared in the field one after another. in order to control the epidemic situation and avoid expanding the harm, farmers are called on to strengthen field inspection and continue to cooperate with prevention and control operations in order to "detect and control as soon as possible."

According to the statistics of the Prevention and Inspection Bureau, as of September 24, a total of 557 notifications of type confirmation of military insects and 1396 adults have been found in autumn. At present, a total of 81 pieces of destruction (21.79 hectares) and 449 cases of pesticide control (1661.68 hectares) have been destroyed, and 27 cases remain to be dealt with.

The Agriculture Department of Yunlin County recently reminded farmers that corn, sorghum, Coix, rice, sugar cane and forage grass are all high-risk crops damaged by military pests in autumn, so it is necessary to step up field inspection and prevention work. Liao Peizhi, director of the Yunlin County epidemic Prevention Institute, said that the number of adults captured in Taixi, Mailiao, Sihu and other areas of Yunlin County has increased recently. On the one hand, the hard corn planted is more harvested and managed extensively, and the frequency of field inspection and management attention are already relatively low. Second, night moths are prone to occur from July to September every year. Coupled with the high temperature and shortened insect cycle this year, the breeding speed may increase.

He pointed out that at present, corn is the main preferred crop for autumn insects found on this island, while Yun, Jia and Nan are the main producing areas for the second phase of hard corn in China (the declared / contracted planting areas are 847ha, 4961 ha and 6190 ha respectively). Farmers should strengthen field management so as not to allow autumn insects to take advantage of them. "Maize is most likely to be eaten by insects 14-20 days after planting, because the leaves are the most tender and delicious at the initial stage. Therefore, prevention and control should be done immediately at the initial stage of planting, so that the harm of insect pests can be controlled immediately. "
