Abstract

The three most common artificial containers found in natural environmental conditions, are discarded tires, plastic and glass objects. These were tested to verify the effectiveness of hexanic (CRH) and methanolic (CRM) fractions of the oil-resin, from Copaifera reticulata (Ducke) (Leguminosae-Caesalpinoideae) against 3rd instar larvae of Aedes aegypti (Linnaeus) (Diptera - Culicidae). Larvicidal activity was noted in all the containers, varying according to type. The glass and plastic containers interfered less in the larvicidal activity than the tires. The most promising fraction was CRH1, which presented 18.2 of LC90. Glass containers and tires presented LC90 of 18.8 and 42.8 ppm respectively.
