Abstract
House fly intensity at five different poultry farms in Namakkal region of Tamil Nadu was
monitored by spot cards. A plain white sheet of 12.5×7.5 cm square was pinned to
thermocole of similar size and tied to cages above two feet from the floor in narrow caged
poultry houses and three feet above from the floor in high rise caged poultry houses. After
24 hours, the spot cards were removed and the regurgitation and faecal spots made by
adult flies were counted. The mean number of fly specks per card was 59 ± 8 in farm-I,
195 ± 28 in farm-II, 63 ± 12 in farm-III, 34 ± 5 in farm-IV and 101 ± 19 in farm-V. About
50 gms of manure collected in different points of selected farms were pooled and moisture
estimation was carried out by oven drying method. The moisture content of manure was
67.49, 86.32, 48.64, 41.56 and 79.11 per cent in farm-I, farm-II, farm-III, farm-IV and
farm-V respectively. Higher fly population was observed in farms (I, II and V) that had
manure moisture content > 60 per cent and mild to moderate level was noticed in farms
(III and IV) with moisture level ranged between 40 and 50 per cent.
