Inchworm, a lepidoptera pest, is the larvae of the ulnar moth. Adults are infested, and the larvae are harmful and feed on plant leaves. In China, the inchworm is divided into about 43 species, which harm tea trees, mulberry trees, fruit trees, octagonal trees and forest trees.
Inchworm, commonly known as bridge-building insects. When crawling, arch into a bridge.

Inchworm, adults are ruler moths. Adults are mostly feathered in the evening, and can be tailed on the same day after feathering. Female moths mostly lay their eggs in cracks and wall crevices of tall trunks, preferring to lay on the sunny side. Adults tend to light, and male moths are good at flying.
When it first hatches, it is 1 year old, and the 1st to 2nd instar insects only eat leaf flesh and do not eat leaf veins. After 3-4 years of age, picky eaters, nibble a few bites after changing the position and then eating, often nibbling the leaves into a lack of carving. After the 5th instar, the amount of food increased greatly, reaching more than 80% of the entire larval stage.
In mid-April of the following year, butterflies break out of the cocoon to lay eggs and hatch, and 2-3 generations occur every year.
The body is slender, and it flexes and stretches like an arch bridge when crawling. When pausing, the body can stretch forward like a branch and look like it is sitting up.
Inchworm adults are inchworm moths, which tend to light and are good at flying.

The harm of inchworm is large, mainly due to the large amount of food of the older larvae, if not managed, the group larvae will soon eat the leaves. But in fact, the resistance of inchworm is not strong, and many agents can achieve a good control effect.
When inchworm occurs severely, the leaves can be eaten in a short time.

When spraying, as many leaves, trunks, branches and the ground as possible should be sprayed, it is not easy to take the medicine, and it is more thorough to kill.
If you use a plant protection drone to spray medicine, the amount of medicine per mu is consistent with the above. However, when the canopy is large, it is not easy to penetrate, and it is resprayed once every 3-5 days. #三农高热选题创作 #
