Abstract: A field study was conducted to evaluate the larvicidal effect of diflubenzuron spraying of fly breeding sites on a cattle farm In Hungary. 0.1% and 1.0% aqueous solutions of Dimilin® WP-25 were sprayed once at a rate of 0.7 g/sqm and 0.5 g/sqm effective substance in a calf house and in a cow barn, respectively. Fly rearings from the samples taken before and after spraying indicated that the fly community had considerably changed due to the treat-nent. Although the numbers of Musca domestica and Coproica hirtula imagoes emerging from the calf house samples were higher after the treatment than before it, signs of damaged chitin synthesis were found in 80% of Muscid pupae and in 9% of C. hirtula imagoes. The extreme decrease of total Diptera, the numerous abnormal, dead Muscid praepupae, and the total lack of para-sitoids in the cow barn samples taken after treatment give evidence of a high larvicidal effect. Pteromalid parasitoids with irregular cuticle were also found.
