Autumn military insects invade China: autumn military insects fly to Miaoli with the airflow. What is the harm of autumn military insects?

Autumn army worm larvae have appeared in Taiwan! The Council of Agriculture was informed last Saturday that the larvae of suspected autumn army insects were found on the green-cut corn in the Feiniu pasture of Miaoli County. After morphological identification and genetic sequence, the experts confirmed that they were autumn army insects. The Prevention and Inspection Bureau of the Council of Agriculture immediately launched pest control measures, adding black fertilizer and burying the corn. However, the sex pheromone trapping facility set up by the Prevention and Inspection Bureau has not found any adults so far. Since so far only larvae have been found in corn, there is hope to stop the spread of autumn bugs in Taiwan.

In addition to the confirmed case of Feiniu Ranch, on the 10th, suspected worms were reported in Toucheng Town, Yilan County and Yizhu Township, Chiayi County, and samples were collected and sent to DNA for identification. From the south-central to the northeast, as the southwest airstream flies not only over the sea, but also over the mountains, after finding traces of the larvae of autumn military insects, the Prevention and Inspection Bureau immediately set up emergency response teams for autumn military and insect disasters, and agricultural bureaus of various counties and cities have also set up monitoring teams, which will hold their first meeting on the 11th to establish a mode of operation for disaster forecasting, warning, disaster collection, and reporting.

The first case of autumn army worm larvae invading Taiwan was found in flying cattle pastures, but not in the fields, but in the sales department in the animal feeding area, where tourists buy green cut corn to feed cattle. People report when they find suspected autumn army insect larvae on the green cut corn sold on pastures, and the prevention and inspection bureau sends personnel together with the agricultural laboratory, Miao to change the farm, and the Miaoli county government to investigate. When he went to the survey on the 8th, he also hung pheromone traps at the scene, and if adults were found, they could be trapped immediately, but so far they had not been caught; at the same time, experts also inspected the surrounding host plants (corn) and found no further.

In order to prevent the spread of military insects in autumn from flying cattle pastures, the Prevention and Inspection Bureau designated the epidemic areas, wiped out and destroyed all the crops in the affected areas, and gave compensation. The way of eradication and destruction is to shovel all the green corn in the field, and add black fertilizer (calcium cyanide nitride). When it comes into contact with water, black fertilizer will release cyanide, which can be sterilized and insecticidal, and then buried 2 meters deep in the ground, it is certain that the autumn army worm can be killed. However, Wufei is a kind of chemical fertilizer, and chemical fertilizer cannot be used in organic fields. once autumn military pests harm organic corn fields, how to deal with them? The prevention and inspection bureau said the issue needs to be discussed with experts again.

There are pesticides that can be used to control autumn army insects. In order to urgently control the autumn army insects found on corn, the Prevention and Inspection Bureau announced the emergency use of drugs on the 10th. It includes 11 kinds of products, such as Zenote, Novarone, Fluorine, KGB, Ephraine, Ifennine, Thiodactamil, and so on. In fact, all pesticides that can be used to kill nocturnal moths can be used. There were originally more than 50 kinds of pesticides, but after excluding the items that were already resistant to drugs. Only these 11 kinds are open. Among them, only Suri is a biological pesticide, and it is the only drug that can be used in organic farming to control autumn army insects.

Autumn military insects are serious agricultural pests in the world, mainly harming: corn, rice, sorghum, cotton, cruciferae, cucurbitaceae, Solanaceae and other cash crops. Eight countries in Asia have fallen: Bangladesh, China, India, Myanmar, Sri Lanka, Thailand, Yemen, and Indonesia, and Taiwan is in jeopardy.

That's the one! The first case of autumn army worm larva was found in Taiwan.
