In my own words, it is the shape of this bug and the way to destroy its offspring.

Paragon is a common name for walking insects, belonging to COLEOPTERA and Reptilidae. There are about 20000 species in the world. They are characterized by long legs and shiny black or brown wing sheaths, and many species have degenerated or have no wings at all.

Walking bugs like to live in wet and cool places. When they are disturbed, they will run away or fly away with their legs. Most larvae are carnivores, and only a few are herbivores. They all have pointed and hollow mouthparts and a pair of setose tail appendages. Many kinds of walking insects can secrete an unpleasant liquid to scare away their enemies, birds.

Control methods ① can reduce the planting area of wheat in southern China where armyworm can successfully overwinter, and reduce the number of overwintering generation and first generation insect sources. The combination of intertillage and weeding in autumn has obvious effect on controlling the third generation of armyworm. ② From the early emergence of the adult armyworm, sweet and sour solution, black light or hay can be used to trap and kill adults or eggs in a large area. ③ When there are 20-30 larvae in 100 plants of maize and sorghum at seedling stage, or 50- 100 larvae in 100 plants of maize at middle and late growth stage, pesticide treatment should be carried out. Before the 3rd instar, apply diflubenzuron 1 active ingredient 15-30g or diflubenzuron-3 active ingredient 5- 10g per hectare. After adding water, the drug effect can last for 20 days. You can also spray 90% trichlorfon 1000 times or 80% dichlorvos 1000 times, or 50% phoxim EC 1500 times or 25% omethoate EC 2000 times. ④ The natural enemies of the armyworm are frogs, birds, bats, spiders, nematodes, mites, predatory insects, parasitic insects, parasitic bacteria and viruses. Among them, scarab can prey on a large number of armyworm larvae, and the parasitic rate of armyworm flies to the first generation of armyworm is high. In some areas, the parasitic rate of nematodes to myxomycetes larvae is high. Sparrows and bats can prey on a large number of adult myxomycetes, while ladybugs, grubs eating aphids and lacewings can prey on young larvae. All localities can adjust measures to local conditions and pay attention to protection and utilization.
