Introduction to the Study of , as a Mosquito Control Agentn of improved strains and in the energy presently evident in this most interesting research area. We are all even more pleased that industry (Abbott Laboratories in the United States and the Biochem-Solvay group in Belgium) has decided to consider, seriously, the development of material for field use.

Classification of , Strains and Comparative Toxicity to Mosquito Larvae, in 1989 more than 150 mosquito pathogenic isolates with various toxicity levels have become available. This has created problems in their identification and differentiation—first from the atoxic ., and second from each other within the toxic group.

Michael Massengale,Elise Choe,Don E. Davis pests. However, the disadvantages of chemicals are that they persist for a long time in the environment; are hazardous to humans; and due to chemical longevity, genetically based resistance to the chemicals occurs. Consequently, the development of biological controls as an alternative means of pest control is desired.
