Recent discoveries of new bacterial isolates specific to new hosts and recent genetic improvements in these isolates have created the potential for wide-scale use of these biological control agents. Efficient microbial control of mosquitoes and black flies can now be achi978-94-011-5969-2978-94-011-5967-8

Transfer of the , Mosquiticidal Toxin Gene into Mosquito Larval Food Sources 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.

In general, however, the pest status of black flies in temperate climates does not stem from these medical problems, but rather from the annoyance caused by their flying and biting.
