Operation note on dengue vector control against Aedes albopictus in Chiba City, Japan, where an autochthonous dengue case was confirmed in September 2014
Medical Entomology and Zoology 66 (2), 31-33
Abstract: An autochthonous dengue patient was confirmed on September 8, 2014 in Chiba City, Japan and emergency control against potential dengue vector Aedes albopictus was implemented in the residential area where the case was found. We examined the distribution of human dwellings and areas with trees and bushes in the residential area by using an aerial photograph, selected an operation area within 100 m radius of the patient's house, and carried out vector survey and insecticide spray in the operation area. The mean biting density of Ae. albopictus examined at six collection sites within the operation area was 2.8/person/8 min before insecticide applications. Etofenprox 7% and phenothrin 10% diluted 1/50 were applied to adult resting sites and larval habitats of Ae. albopictus at a rate of 500 mL/m² and 50 mL/m² with a power-driven sprayer and hand-pump sprayers, respectively. Additionally, a liquefied carbon dioxide formulation of phenothrin was applied at a rate of 1 g/m² to drains with a heavy cover. The mean biting density was reduced to 1.2/person/8 min on the same day after insecticide application, and weekly inspections of the operation area in the following 3 weeks found a total of four mosquitoes.
