Resumo: The Asian tiger mosquito Aedes albopictus (Skuse) is rapidly increasing its global range - importance in transmission of chikungunya - dengue viruses. We tested pellet formulations of a monomolecular film (Agnique) - (S)-methoprene (Altosid) under laboratory - field conditions. In the laboratory, Agnique provided 80% control for 20 days, whereas Altosid, in combination with Agnique, provided 80% control for > 60 days. During field trials, the 1:1 pellet ratio of combined products provided > 95% control for at least 32 days - 50% control for at least 50 days. Altosid remained effective after a 107-day laboratory-induced drought, suggesting that the product serves as a means of control during drought conditions - against spring broods in temperate regions. Agnique - Altosid, when used in t-em for cryptic, difficult-to-treat locations, can provide long-term control of Ae. albopictus larvae - pupae. The possible additive or synergistic effects of the combined products deserve further investigation.
