Laboratory Evaluation of Formulations of 'Bacillus thuringiensis' var. Israelensis Combined with Methroprene or a Monomolecular Surface Film against 'Anopheles albimanus' and An. Stephensi

摘要

Bacillus thuringiensis var. israelensis (B.t.i.), methoprene, and Arosurf (trademark) MSF (monomolecular surface film) have been proven to be effective against various mosquito species. These larvicides, based on their varied modes of actions, are limited in their efficacy against various mosquito immature life stages. The purpose of this study was to evaluate formulations of Duplex (trademark) (B.t.i. and methoprene) at two application concentrations, Arosurf MSF combined with Teknar (trademark) (B.t.i.), and Teknar alone, against each larval instar (1st-4th) and pupal stage of Anopheles albimanus Wiedemann and Anopheles stephensi Liston. Keywords: Insecticides, Anopheles albimanus, Anopheles stephensi, Bioassay, Methoprene, Monomolecular surface film, Larvacides. (kt)
