Biopesticide Weapons Against Agricultural Mite Pests

Most mite species causing damage to important crops worldwide are included in the families Eriophyidae, Tetranychidae, Tenuipalpidae and Tarsonemidae. Plant insecticides act in several ways: as repellents by driving the insects away due to smell or taste; as antifeedants which cause pests on the plants to reduce their food intake and hence starve them to death; as oviposition deterrents; by preventing pests from laying an egg; or as inhibitors by interfering with the life cycle of the pests. Besides direct mortality, botanical pesticides can cause a reduction in fertility, longevity and fecundity of mites. Rotenone, pyrethrum neem products neem oil and wild tobacco (Nicotianagossei) are effective against soft-bodied insects and mites. Obviously, in large-scale field utilization of Botanic agricultural chemicals, there must be an adequate and constant supply of candidate plants to the areas in need.
