Abstract:

Infestation with Ornithonyssus bacoti, the tropical rat mite, occurred in mouse colonies and a hamster colony in Bangkok, Thailand. The infestation in mouse colonies was extensive, affecting most of the animals. In the hamster colony, only occasional cage mates were infested. Following infestation of colony mice, there was a marked decline in production of litters in affected colonies. Treatment of mouse quarters and cages with DDT, coupled with dusting of mice with a silica aerogel insecticide did not control the spread of mites. Infestation in the animal colonies was eradicated effectively by the repeated application of malathion compounds to mice and quarters. Following and during the time malathion compounds were applied, the productivity of the mouse colony returned to the lower limits of the previous normal levels. Author
