Abstract:
The present study is identified (morphologic and molecular )for the population of cucurbit fly which is a destructive pest of cucumber ,honey melon and cantaloupe in Basrah and Missan .Sample were collected from different region from Basrah province including Qurna , Safwan , Zubair , Khor Al - Zubair . Al - Misharah , Kumate , Kalat Salih, Ali Al - Garbi in Missan province for the period October ,2014 till September 2015.Result of the identification study showed there is only one species infect cucurbits which is Dacus frontalis Becker ,1922,family Tephritidae ,Order Diptera in all studied regions. This species was classified according to femur color of the middle leg ,its color is orange at the apical half with dark black spot at the basal part of the antenna with the presence of basal diagonal line underneath the scutum behind the thorax. female were characterized by the presence of ovipositor at the end of the abdomen and male characterized by present s one line of hair at the third of the abdomen ring .For the sensitivity of the insect fly cucurbits towards our fruits of cucurbits (cucumber and water melon represented by the number of eggs laid down by the female as it appeared no significant difference in the number of eggs laid down by the female in the provinces of Basra, Maysan and was the highest rate of lay eggs on the fruits of cucumbers choice of six eggs and a difference of moral on water option, which amounted to one egg.Molecular study show the kit equipped Bioneer company and named Genomic DNA Extraction kit was highly efficient in DNA Extraction it was later used in the Random Amplified Polymorphic DNA - Polymerase Chain Reaction which is one of the methods used in molecular identification .Used four primers for different sequence s. and electrophoresis results shows multiplied bands of different molecular weight for four different primers for both females and males .The number and molecular weight of bands was calculated manually comparative with DNA marker or ladder then used the number of bands in the following equation to find the genetic similarity and genetic distance between the different districts each primer for males and females .To find genetic similarity used the equation : Sfy=2Nfy/Nf+ Ny and to findgenetic distance used the equation : GD fy=1 - SfyAt the level of first primer for females it was less value of genetic distance is zero and this is evidence that one species and highest value of genetic distance is 0.9 on the second level of the primer for females it was less value of genetic distance is 0.2 and highest value of genetic distance is one at the third primer for females it was less value of genetic distance is 0.3 and highest value of genetic distance is one but the fourth primer for females it was less value of genetic distance is 0.3 and highest value of genetic distance is one .For males at the level of first primer of males it was less value of genetic distance is zero and highest value is 0.8 but the second primer of males it was the less value for genetic distance is 0.8 and on the level of genetic distance is zero on the level of third primer for males it was value of genetic distance is zero and highest value is 0.8 and fourth of males it was the less value of genetic distance is zero and highest value of genetic distance is 0.8
