Abstract

Semi-field trials were conducted to evaluate the efficacy of slow-release formulations (SRFs) of Bactimos briquets, Spinosad tablets, Altosid briquets and Dudim tablets against mosquito larvae of Aedes aegypti. The records showed that SRF treatments provided long-term effective control against mosquito larvae using a single application of the test formulations. Effective control with 90-100% inhibition of adult emergence was obtained for 4, 9, 10 and 12 weeks post-treatment by using SRFs of Bactimos, Spinosad, Altosid and Dudim, respectively. On the other hand, the results showed that larval treatments with the test SRFs affected the blood feeding activity and reproductive capacity of mosquito adult survivors.
