Are mole crickets pests or beneficial insects? Are mole crickets beneficial or pests?

Pests, of course.

The newly sown seeds of mole crickets bite the roots of crops, which is extremely harmful to crop seedlings.

Main means of prevention and control:

Agricultural control. Deep soil ploughing and intensive cultivation create an environment that is not conducive to the survival of mole crickets and reduce the harm; After the summer harvest, the ground is turned in time to destroy the spawning grounds of mole crickets; Apply well-rotted organic fertilizer, not unrotted fertilizer.

During the hazard period of mole crickets, ammonium bicarbonate and other chemical fertilizers are applied, and the ammonia emitted has a certain repellent effect on mole crickets. After the autumn harvest, the mole crickets that migrate to the deep layers are forced to migrate upwards and turn deep before freezing, freezing to death the pests that have climbed to the surface.

The implementation of reasonable crop rotation, improvement of saline-alkali land, and the implementation of water-drought rotation in areas with conditions can eliminate a large number of mole crickets and reduce the harm.

2.Light booby-trap.

During the damage period of mole crickets, black lights and incandescent lamps are used to trap and kill adults at the edge of the field or in the village to reduce the density of insect population in the field.

3.Artificial killing.

Combined with field operations, the newly arched mole cricket tunnels are manually dug to kill insects and eggs.

4.Pharmaceutical prevention and control:

Seed treatment Before sowing, use 50% phosphine emulsifiable concentrate, mix seeds according to seed weight, and sow after 12 to 24 hours of heaping.

Poison bait trapping is commonly used trichlorfon poison bait, first wheat bran, soybean cake, corn, cottonseed cake or corn kernels.

The implementation of reasonable crop rotation, improvement of saline-alkali land, and the implementation of water-drought rotation in areas with conditions can eliminate a large number of mole crickets and reduce the harm.

2) Light trapping: During the damage period of mole crickets, black lights and incandescent lamps are used to trap adults at the edge of the field or in the village, and hail is used to reduce the density of insects in the field.

3) Manual killing: Combined with field operations, manual digging is used to hunt insects and eggs for the newly arched mole cricket tunnels.
