Abstract:

Aedes aegypti is the only known vector of dengue, dengue hemorrhagic fever, and dengue shock syndrome in the Caribbean. Since the virus and its vector threaten the well-being of people in the Caribbean, public health authorities in the region support efforts to manage the mosquito vector. During an outbreak of dengue fever in Jamaica during October-December 1995, a study was conducted to assess the impact of aerial ultra-low volume malathion treatment upon adult Aedes aegypti. Researchers monitored oviposition rates of the vector in 3 urban communities in Kingston and exposed caged mosquitoes directly and indirectly to the aerial treatment. The insecticide was delivered at a rate of 219 ml/ha between 7:10 a.m. and 8:45 a.m. This intervention failed to interfere with Aedes aegypti oviposition, and adult mosquitoes held in cages inside dwellings were largely unaffected. This type of intervention therefore seemed to have little impact upon arresting or abating dengue transmission.
