Abstrakt: Influence of citronella and chlorpyrifos on oviposition and duration for completing life cycles for Chrysomya megacephala and Chrysomya rufifacies infesting decomposing rabbit carcasses was studied. Male rabbit carcasses (n = 12) were equally divided into control, citronella- and chlorpyrifos-treated groups, and left to decompose for 14 consecutive days. C. megacephala was the first necrophagous fly oviposited in all control and citronellatreated carcasses followed by C. rufifacies. Although initial oviposition of C. megacephala was delayed (4-6 hours) in citronella-treated carcasses (P andlt; 0.05), prolongation in completing its life cycle was not observed. Neither delayed initial oviposition nor prolonged life cycle for C. rufifacies in citronella-treated carcasses was observed. Oviposition was delayed for chlorpyrifos-treated carcasses (0.42 g/L), and eclosion of eggs remained unsuccessful. The findings deserve consideration because these chemicals are easily accessible and can be used by cunning criminals to confuse forensic entomologists while estimating minimum postmortem interval.
