Toxicity of new pyrethroids to the social insects Protonectarina sylveirae, Solenopsis saevissima and Tetragonisca angustula.

摘要

Pyrethroids are among the most potent and effective pesticides identified with great potential for structural variation with retention or enhancement of potency. Our objective was to evaluate the biological activity of novel methyl esters of pyrethroid acids containing an aromatic ring on the acid moiety against the social insects Protonectarina sylveirae (Saussure) (Hymenoptera: Vespidae), Solenopsis saevissima (Smith) (Hymenoptera: Formicidae) and Tetragonisca angustula (Latr.) (Hymenoptera: Apidae: Meliponinae). The compounds showed low toxicity to all species tested. P. sylveirae was the most sensitive to pyrethroids.
