Abstract: 
A study was conducted to evaluate the larvicidal and pupicidal efficacies of neem in comparison with cyromazine in poultry since fly menace is a serious problem in modern poultry industry. One hundred and ninety two layer birds of twenty four weeks were randomly divided into eight groups of twelve each with two replicates and the study was conducted for a period of six weeks. Cyromazine (1%) and powdered neem seed were mixed in the feed at the dose rate of 500 gm and 1 Kg per tonne of feed, respectively and fed throughout the experimental period and neem oil (5%) was sprayed on litter twice a week until the completion of the study in the treatment groups. Various combinations of these treatments were also used in addition to individual treatments. Pupicidal activity was observed on 5th day by in vitro method after spraying neem oil on 3rd day. All the feed incorporated treatments possessed good larvicidal activity on 14th, 28th and 42nd day. Mere spraying of neem oil possessed good larvicidal effect only on 28th and 42nd day. Pupicidal activity was significant in neem oil sprayed group compared to that of control on 5th day of treatment. It may be concluded that dietary inclusion of neem seed and neem oil spray in litter material showed good larvicidal activity and it was very economical to the poultry farmers. The efficacy of neem products was comparable with that of cyromazine and their combinations were synergistic.
