Abstract :The house fly, Musca domestica L., 1758 (Diptera: Muscidae), is a public health pest commonly found on animal farms, manure heaps, and garbage dumps. In agricultural and livestock areas, house flies are frequently exposed to pesticides used against various pests, which leads to the development of insecticide resistance. This resistance complicates their control and has prompted researchers and insecticide manufacturers to explore alternative control strategies and methods. This study examines the effects of insect growth regulators (IGRs), specifically diflubenzuron and pyriproxyfen, used as larvicides, on egg yield, egg-laying index, and egg-to-adult transition rates in six different house fly populations. These populations were collected and cultured from five Turkish provinces (Antalya, Bursa, Edirne, Gaziantep, and İzmir) between June 2020 and August 2021, as well as from a susceptible population provided by the World Health Organization (WHO). The adult house flies were fed sugar solutions (40%) containing either 5% or 10% concentrations of diflubenzuron and pyriproxyfen. Our findings show an 80% reduction in egg yield and a 90% reduction in adult emergence rates across all populations compared to the control group. Although exposure to IGRs significantly decreased egg area indices, it did not affect the egg to adult transition rate.
