Abstract

The most important practical problems faced by everyone concerned with regard to BPH management are its extraordinary ability to develop insecticide resistance and also its ability to overcome the barrier of resistant varieties. A critical analysis of the whole of the information available till date reveals that nitrogen recycling and steroid biosynthesis mechanisms coevolved in BPH and its symbionts along with high plasticity in the multifunction oxidases, glutathione-S-alkyl transferases and other enzyme complex of BPH appear to the most important physiological mechanisms that aid the destructive insect pest to realise high reproductive ability, there by greater diversity within the population and between the populations and finally establishing the insect biotypes capable of feeding on resistant varieties and also render the insecticides completely non-toxic within few years.
