Abstract: | A large number of viruses, bacteria, fungi and protozoa can kill or incapacitate insects. Some of these have the potential for a significant role in the management and regulation of pest species of insects, either as naturally occurring entomopathogens or as applied or introduced insecticidal agents. The usefulness of entomopathogens, especially the feasibility of development as microbial insecticides, is examined by consideration of their effectiveness, safety and specificity, production and propagation, and marketability and profitability. Effectiveness, a major consideration in assessing potential, is influenced by several factors including efficacy, dissemination, persistence, compatibility with other regulatory agents, and establishment in the host population, and by factors such as humidity, temperature, chemicals, and formulation, that directly influence the activity of the pathogen. |
