System for fly control in public areas of urban waste in Brazil

Abstract:
A Musca domestica (L.) control method in final solid waste disposal areas (recycling and composting facility and waste transfer station) was developed. The application of two fly control products based on azamethiphos (Alfacron 10 Plus, a wettable powder containing 10% a.i. and Snip, a ready-to-use granular bait containing 1% a.i., both from Novartis Animal Health Inc.) was done on different surfaces. On vertical surfaces, represented by boards painted with diagonal red, yellow and white stripes, the wettable powder was used as spray or paint-on. The granular bait was used on horizontal surfaces, such as walls, floors and windowsills. Fly infestation was evaluated with Scudder Fly Grills. In the pile areas, reductions of 98.5% and 100% were achieved 18 and 30 days respectively after application. In the waste transfer station 85.6% and 98.7% reduction was achieved over the same period of time. A survey among employees of the plant revealed a high level of satisfaction with the achieved control. The present study showed that one application of azamethiphos in different formulations was effective against M. domestica for 30 days. Since the area is subject to continuous waste accumulation and management, it is fundamental that regular and monitored fly control is performed.
