Field evaluation of deltamethrin/S-bioallethrin/piperonyl butoxide and cyfluthrin against dengue vectors in Malaysia

Deltacide(R) (S-bioallethrin 0.71% w/v, deltamethrin 0.5% w/v, piperonyl bu toxide 8.9% w/v excipients to 100% w/v) and Solfac UL 015(R) (cyfluthrin 1. 5% w/v) were evaluated against the sentinel sugar-fed adults and 4th-instar larvae of Aedes aegypti at 17 storey high-rise apartments in Malaysia usin g ULV applications. The impact of both insecticides on field populations of Ae. aegypti and Ae. albopictus larvae was monitored weekly using bottle co ntainers. Both Deltacide(R) and Solfac UL 015(R) showed adulticidal and lar vicidal effects. This was the first field trial using Deltacide(R) against dengue vectors in Malaysia and showed its potential for use in dengue vecto r control programs.
