Tianfu's natural calendar 丨 The name is very sweet, smelling the stink (July 8, 2022)

When I was a kid, I particularly hate a kind of worm -the body was flat. As long as it was where it stayed, it would definitely leave a strong smell, which is called "stinky fart" lychee.

Litchi is also known as lymi and lychee 蝽 蝽. Looking at the appearance alone, it is still pretty. Adults are 21-26 mm long and 11-13 mm wide. The body is red and brown, looks like a small shield, and the surface of the small shield is recessed to form a spoon. The edge of the shield is gray, with red stripes on the back.

Although it looks beautiful, lychee is the main pests of litchi and longan. It specializes in juice of young leaves, flowers, and young fruits, causing falling flowers and fruits to reduce production. Studies have shown that the biggest natural enemy of lychee is spiders, followed by predation insects and insect birds.

In addition, the nickname of Litchi "Stinky Fart" is also not famous. When it is frightened, it will secrete a stinky liquid, which is extremely stinky, and has corrosion effects, which not only affects fruit trees, but also damages people's eyes and skin.

Practice shows that during the early spring of the winter, adults began in the event, that is, in mid -to -late March. At this time, adults were about to lay eggs, and the most resistant to drug resistance. At this time, killing adults to kill adults can significantly reduce the base of the insect mouth, which is beneficial to the entire year's prevention and control. Another period of prevention and treatment was in mid -to -late May. At this time, it was a period of ovil that had an egg that had been hatched in large quantities. The first to second -year -old nymphs were waxy, low keratinization, and was more sensitive to drugs.

In addition to the prevention and treatment of drugs, it can also be used to control the biological control by dispersing flat bee gardens, or use bamboo poles to tie the cloth group and dip the urine and kerosene to smoke the nymph for artificial killing.
