This review of ultralow-volume (ULV) ground aerosols for adult mosquito control includes discussion on application volume, aerosol generators, droplet size, meteorology, swath, dispersal speed, assay methods, insecticide efficacy, and nontarget effects. It summarizes the efficacy of ULV insecticidal aerosols against many important pest and disease-bearing species of mosquitoes in a wide range o...

A new cage was designed to study caged mosquitoes in ultra-low volume insecticide spray studies in the field. Insecticide droplets may enter the cage from any direction because all surfaces are mesh. Cages can be collapsed in seconds, and reassembly is quick and simple. A 26-cm-diam cage can be constructed for less than US$6.00.

The insecticide DDT has been an effective and affordable means of malaria control in many countries, but pressure for its use to be banned is mounting. Here, Chris Curtis and Jo Lines take a critical look at evidence that links house spraying by DDT with harm to the environment and human health, and stress the need for resources for alternatives to DDT to be made available to countries that wou...

Organochlorine pesticides are present in the environment and suspected of causing serious health effects. Diet has been the main exposure source, but indoor source release is gaining focus. Within a monitoring study of polychlorinated biphenyls of Danish buildings built during the 1960s and 1970s, we coincidently determined extreme levels of dichlorodiphenyltrichloroethane (DDT) levels in two o...

Auditory Processing Tests, including the PPST, the DDT, the HINT, and the RGDT, were administered to normal hearing adults between the ages of 20-40. No differences were indicated between results of the Control and Experimental groups, though differences within the Experimental group were noted on the DDT, the HINT, and the RGDT.
