Control of Adult Manure Breeding Flies in High Rise Poultry Houses With Ectiban, 1979

Abstract

Abstract Two high rise poultry houses located in Lancaster Co., PA were used to evaluate residual wall treatments of Ectiban (permerhrin) for controlling adult manure breeding flies. Single applications of 0.1% Ectiban were applied by a hand held compressed air sprayer to the manure pit walls of each house at a rate of 1 gal/^50 sq ft. Alternating 750 sq ft sections were treated. Changes in adult fly populations were monitored by counting the number of flies resting within marked areas on the walls in both treated and untreated sections of the pit and upper level of the building where the birds were housed. The house at Rheems, PA was 400 × 52 ft and housed 60,000 caged layers. The flock had been in place since February and no fly control measures had been taken. A total of 5 gal of spray was applied to 52% of the wall area in the manure pit on Jun 22. The 8 ft high pit walls had cinder blocks on the lower half and unpainted wood paneling above. The upper area where the birds were housed was not sprayed but was treated with 10 to 15 lb of Improved Golden Malrin (Lannate) fly bait at 3, 7, 14 and 21 days post-treatment. The manure pit was cleaned Aug 6-8. House flies comprised 20% and Ophyra sp. 80% of the adult fly population. The house at Ephrata, PA was 500 × 44 ft and housed 45,000 caged layers. The flock had been in place since November and the pit was cleaned in April. Ten days prior to the Ectiban treatment, the aisles in the upper level were baited with Improved Golden Malrin (Lannate) and the manure surface was sprayed with Shell Poultry Spray & Larvicide (Rabon + Vapona) 2-1/2 weeks prior to treatment. On Aug 14, a total of 4 gal of Ectiban spray was applied to 42% of the wall area in the manure pit. The 8 ft high pit walls had cinder blocks on the lower half and plywood above which was painted with white latex paint. House flies comprised 99% an^ Ophyra sp. 1% of the adult fly population.
