Abstract: | |
Although there is still much work to be done in the field of pest control, however, the insect pests management technologies and information have reached well beyond our thoughts. There are some interesting developments in pesticides technology resulting in the flush of greener products and among these are existences of biochemical pesticides. The goal of this paper is to emphasis on the use of reduced-risk chemicals for insect pests controlling needs as alternatives to riskier conventional pesticides. The reduced risk designation can be applied only to certain uses of a particular chemical such as biochemical pesticides that are naturally occurring and control pests through non-toxic routes. Examples of biochemical pesticides categories are semiochemicals (chemical signals) including pheromones (acting between individuals within a species) and allelochemicals (acting between individuals of different species), hormones, plant extracts, enzymes, feeding deterrents, repellents, confusants, plant growth regulators and insect growth regulators. Pesticides to be included in these categories must be naturally occurring, or if man synthesizes such chemicals, and then these must be structurally identical to naturally occurring chemicals. Because biochemical pesticides are naturally occurring they pose much less health and environmental concerns than conventional pesticides. Methods for crop protection based on semiochemicals show advantages over methods based on conventional insecticides. Applications of semiochemicals for insect pest management however, have been limited. Some recent studies carried out in an interdisciplinary research program are presenting that in spite of the chemodiversity in nature, it is striking that many simple and common compounds are important as chemical signals. Biochemical pesticides have been expediting the review of conventional pesticides that meet certain criteria such as low toxicity to humans and nontarget organisms including fish and birds, low risk of ground water contamination or runoff, low potential for pesticide resistance, and demonstrate efficacy and compatibility with integrated pest management (IPM). |
