Abstract
This study has been performed in Beshir area at north of Diyala city by planting seven species of cucurbit family plants through out the spring and fall seasons of 2014 , the field results of sensitivity test for the tested species to the infection of cucurbit fruit fly Dacus ciliatus (Loew(that the infection rates Shows in spring season are 74.37% , 41.89% and 11.62% for bottle gourd ,cucumber and snakemelo, respectively. While the rates for fall season were 88.39% ,69.09% and 45.25% respectively , and yield loss 51.37% , 26.61% and 13.02% in the spring season for bottle gourd , snakemelon and cucumber , 29.99% , 21.43% and 4.04% in the fall season respectively , the studied species were different in sensitivity degree to infect by the insect , bottle gourd , cucumber and snakemelon has the highest values of the studied criterion which are infection rate , yield losses ,loss in fruit length number of infection spots per fruit , the number of larvae per fruit and number of deformed fruits , making them the most sensitive species to infect by the fly , on the other hand watermelon , melon , pumpkin and squash observed to be non infected species , there fore they are not preferable species by the insect
