چکیده
Field studies were carried out to evaluate the attractiveness of different food attractants viz. protein hydrolysate 10%, torula yeast 10%, yeast instant 7%, casein 5% and sugar molasses 10% towards the fruit fly, Bactrocera species in pear orchard. The above mentioned food bait concentrations were prepared in 200 ml of water and transferred to locally designed traps. The traps were hung in the fruit orchard on trees at a height of about 2 m. No toxicant was used in the food attractants. Data were regularly recorded at weekly intervals on the number of B. zonata or B. dorsalis captured, their sex ratio and aggregate population of both the species. Results revealed that yeast instant attracted significantly higher number of B. zonata and B. dorsalis and hence the highest cumulative population of both species followed by treatment of sugar molasses and protein hydrolysate. Among all the treatments, torula yeast was found to be the least preferred attractant for B. zonata and B. dorsalis. Sex ratio (%) of B. zonata and B. dorsalis captured in different food baited traps revealed that all the baits attracted significantly higher number of female flies than male flies except treatment of molasses. The highest percentage of female flies was recorded from traps baited with protein hydrolysate. The results manifested that yeast instant, sugar molasses and protein hydrolysate were highly effective and could further be exploited in combination with certain chemicals in order to enhance their attraction towards fruit flies and developing a strong fruit fly attractant.

چکیده [English]
Field studies were carried out to evaluate the attractiveness of different food attractants viz. protein hydrolysate 10%, torula yeast 10%, yeast instant 7%, casein 5% and sugar molasses 10% towards the fruit fly, Bactrocera species in pear orchard. Different concentrations of food baits (as mentioned above) were prepared in 200 ml of water and transferred to locally designed traps made up of 1.5 liter cold drink plastic bottles. The traps were hung on fruit trees at a height of about 2 m and at appropriate distance from each other. No insecticide was used in the food attractants. Data were regularly recorded at weekly intervals on the total number of B. zonata or B. dorsalis captured their sex ratio and aggregate population density of both the species. Results showed that yeast instant attracted significantly higher population of B. zonata and B. dorsalis and hence the highest cumulative population of both species followed by treatment of sugar molasses and protein hydrolysate. Among all the treatments, torula yeast was found to be the least preferred attractant for B. zonata and B. dorsalis. Sex ratio (%) of B. zonata and B. dorsalis revealed that all the baits attracted significantly higher number of females than males with highest female percentage in protein hydrolyzate and the lowest in sugar molasses. The results showed that yeast instant, sugar molasses and protein hydrolysate were highly effective and could further be exploited in combination with certain chemicals to enhance their effectiveness and developing a strong fruit fly attractant.
