Comparing two different Insect Growth Regulators in Anopheles stephensi

Background: Malaria is the most common protozoal infection of tropical regions. In Iran it is mainly seen in south and southeast, where 80% of all malaria infections are reported. Wide usage of insecticides, development of carriersʹ resistance and also environmental pollution are critical issues that seek further attention. Bearing these in mind, Insect Growth Regulators (IGRs) seem to be effective alternatives. Materials and methods: We have compared the larvacidal and emergence inhibition properties of two common IGRs: diphlobenzorone and methoprene (altosid). Our experiments were performed according to the WHO standards and larval death and emergence of mature anopheles were determined. ANOVA was used for statistical analysis. Results: We have found no significant difference in emergence of mature anopheles, however, there was significant difference based on larval death rate.(p<0.05) Conclusion: Both tested IGRs have shown to be effective on immature anopheles, however. diphlobenzorone cause greater larval death.
