Field evaluation of four biorational larvicide formulations against Anopheles albimanus in Honduras

Abstract
Four biorational larvicide formulations: Teknar (B.t.i.), Arousurf MSF (monomolecular Surface Film), Arousurf MSF combined with Teknar, and SAN-809-I ([s]-methoprene combined with B.t.i.), were evaluated against naturally occurring populations of the malaria vector mosquito Anopheles albimanus Wiedemann in Honduras. All formulations reduced the mean number of larvae per sample area to 0 within 48 h after treatment, and gave significant (P < 0.05) control when compared with similar untreated areas for at least 10 days after treatment. It is concluded that each of these four formulations can be used effectively to control the larvae of A. albimanus in Honduras.
