PROSPECTS IN THE MICROBIAL CONTROL OF AGRICULTURAL INSECT PESTS

Microbial control of agricultural pests, a specific method, is being considered with some interest, enhanced by a better reliability of the recommended methods. The entomopathogenic germs are subjected to exhaustive tests and thorough investigations of their biology. Though underestimated for a long time, both the high genetic variability of a species and the parasitic specificity of some clones are now better known. The biological characteristics of the strains can be better analysed as the genome is better identified due to the progress in molecular biology. Moreover, the production technologies have improved enough to induce the necessary participation of industrial partners. These developments are strengthened by a increased control of field treatments, optimizing the timing, doses, and formulae involved.
