In fact, in the insect ecosystem of nature, there is no distinction between "pests" and "beneficial insects", "pests" and "beneficial insects", but only labels imposed on insects by human beings from their own interests (agricultural production).

Cricket Hazards:
Crickets are important agricultural pests in northeast China, north China, the lower Reaches of the Yangtze River and South China, destroying the roots, stems, leaves, fruits and seeds of various crops, and the damage to seedlings is particularly serious. In the south, 11 to 30% of peanut seedlings are destroyed by crickets, which also harm corn, jute, tobacco, cotton, soybeans and cassava.
