White grub, also known as "Lara Bee" and "Lara Bee", is a common pest, which will harm a variety of agricultural crops, not only eating its stems and leaves, but also being good at digging, even the roots of plants.
Although the mole is a bug, because the people call it a local dog, it will not kill the mole who enters the house, but send it out of the house. This is because there has been a saying among the people that dogs come for money and cats come for their lives.
Although the mole is not a real dog, people do have the word dog in their names after all. It is considered a good thing for local dogs to enter the house, so most villagers will not do harm to the mole who enters the house. This is just a statement.
Biological characteristics of Gryllotalpa
North China and East China have a long life history, and both overwinter as adults or nymphs under the soil. North China mole cricket completes one generation in three years, with nymph 13 years old; Oriental mole cricket is one year 1 generation or two years 1 generation (northeast), and the nymph is 6 years old. A year's life of a mole can be divided into six stages: winter dormancy, spring awakening, migration, rampant harm, summer spawning and autumn harm.
When the temperature drops, this area begins to move underground in late June, 10, with one nest and one insect, head down, and dislikes gregarious living. Most of them live in frozen soil and above the groundwater level, overwintering with adults and nymphs, and then turn around and move to the surface when the temperature rises above 8℃ in the following year.
From the end of April to the beginning of May, the wintering mole began to move. After reaching the surface, the virtual mound is first raised. The virtual mound in North China is about 15cm, which is larger, while the virtual mound in East China is about 10cm, which is smaller. This is the best time to investigate the mole and kill it manually.
