Crickets are orthopterous insects of the family Gryllidae; many are plant and household pests.
Crickets vary in their feeding habits; many are omnivorous. The field cricket [Acheta assimilis] attacks most crops and is a serious pest of cotton in the USA. The Mormon cricket [Anabrus simplex] is a pest on crops and rangelands in the northwestern USA. A number of subterranean crickets subsist largely upon roots and are quite injurious when abundant in crops, gardens and young forest plantations; for example, the mole cricket [Gryllotalpa hexadactylo] eats the roots of seedlings and is particularly destructive of tobacco and vegetable crops in North America and the West Indies. The slashes of the snowy tree cricket [Oceanthus neus], weaken the twigs and canes of various fruits.
