Abstract
Fruit flies are serious pests. It causes serious damage due to the laying of eggs and the feeding of larvae on fruits. This study aim to therow light on eclogical, biological and enhansecment of protien baits to fruit flies.There was significant numerical superiority of the Peach Friut Fly over the mediterranean fruit Fly population in the three crops in which the population were studied and in infested friuts. The (PFF) was existed in pear orchards from the middle of April until the middle of December and peaked in September over the two seasons. In fig orchards it was noticed in mid-May to the end of December and peaked in September in the first season and October in the second season. In mango orchards, the infection began in early February and continued until the end of December and peaked in October in both seasons. A positive correlations were found between the temperature and humidity on the PFF popularion. The correlation in the MFF population was positive with the temperature while the correlation was negative with the humidity. Biological studies showed that Mango fruits were the best suited for rearing peach fruit fly because it have shorten life cycle, lengthen life of whole individuals and lengthen egg laying period, meanwhile the fruits of the fig were not suitable for the rearing insect because it lengthen life cycle,shorten the age of adult insect, lowest fertility and hatching rates and short egg laying period.While rearing insect on the fruits of pear or the artificial diet were more suitable for rearing insect. To evaluate the efficacy of ammonium compounds for enhancing attractability of protien biats for fruit flies, an experiment was conducted, the obtained results showed that mixing of the buminal with the di-ammonium phosphate resulted in a significant increase in the number of insects more than the use of the buminal alone
