The melon fruit fly, Zeugodacus cucurbitae, is a major pest of cucurbitaceous fruits. Insecticides are commonly used to control this pest. However, environmental factors can reduce lethal doses to sublethal levels. Additionally, adult flies might only receive sublethal exposure due to limited contact during spraying. This study aimed to determine the sublethal effects of fipronil 5 SC, spinosad 45 SC and malathion 50 EC insecticides on mating and remating performance in Z. cucurbitae. Adults were treated with LC20 of insecticides through topical application and the experiment included four combinations: (1) treated female and treated male (F+M+); (2) treated female and untreated male (F+M-); (3) untreated female and treated male (F-M+); (4) untreated female and untreated male (F-M-). Fipronil treated flies exhibited significantly lower mating percentage (75%-females, 60%-males). However, mating percent in spinosad and malathion was on par with control group. Contrary to this, a significant decrease in remating percentage was noticed in all the insecticide treatments. These findings underscore the adverse effects of sublethal insecticide exposure on reproductive performance in melon fruit fly, which may alter population dynamics and the efficacy of pest management strategies.
