Comparison of Ground and Aerial Ultra-Low Volume Applications of Malathion against Aedes aegypti in Santo Domingo, Dominican Republic
Abstract
Efficacy of ground and aerial ultra-low volume (ULV) applications of 91% malathion at 438 ml/ha against Aedes aegypti in the Dominican Republic was evaluated using indoor collections, oviposition trapping and adult sentinel mortality rates. Ground compared to aerial ULV applications in this study were found to have a greater effect on Ae. aegypti when measured by the described sampling techniques. Rigorous environmental sanitation and source reduction are the proven long-term control methods against Ae. aegypti, but these methods are neither routinely nor uniformly practiced in many nations. Even with a long-term vector control program, natural catastrophes (hurricanes, floods and earthquakes) and man-made disasters (wars) create conditions favorable for large Ae. aegypti populations, which can lead to epidemic outbreaks of dengue and dengue hemorrhagic fever.
