Abstract

The blowfly Chrysomya putoria was also capable of causing secondary myiasis due to its wide distribution in the Neo tropical region. The excessive use of synthetic insecticides has led to the development of pest resistance, resulting in diminished efficacy and detrimental consequences for the environment. Botanical insecticides give a different option to synthetic pesticides. Despite some reports of its insecticidal activity against some insects, no studies have been conducted on its efficacy against flies. A study was conducted to determine the effect of Ocimum basilium having essential oil on Chrysomya putoria at the post embryonic developmental stage. The Indian Laboratory established and maintained colonies of Chrysomya putoria. There are 6 concentrations of basil essential oil (5.14, 9.36, 21.65, 42.30, 62.90 and 81.30 mg/mL). Regular records of death rates and life cycle alterations were maintained. Basil essential oil contains β-caryophyllene, β-selinene, and eugenol. According to the experiments, there was a direct decrease in the viability of the fly at all concentrations tested, with the LC50 calculated at 8.50 mg/mL of oil. Also, at lower concentrations, the essential oil changed morphology of the abdomen, wings and pilinum. Chrysomya putoria, a disease vector blowfly, can be controlled with this essential oil.
