This experiment was conducted during autumn growing season of 2016-2017 under unheated greenhouse environment at the field station of college of Agriculture-University of Tikrit to study the effect of seaweed, and organic extracts spraying on growth and yield of tomato's (Lycopersicon esculentum Mill) three hybrids. The following nutrients were used; Alga600, Seaweed, and Max in addition to control treatment. The three hybrids were; Rakan, Bushra, and Sadouf. The experiment was designed using split plot design with two factors. The experiment results showed that the organic nutrient Alga600 significantly dominated on fruit average weight (146.00 gm. each fruit-1, individual plant yield as it was recorded for 2.33 kg. each plant-1, number of fruits for each plant (16.59 fruits. each plant-1, the yield of experimental unit (46.67 kg), total greenhouse yield (3981.33 kg. each greenhouse-1), texture toughness of fruits, and the pH was 4.88 of nutrient at concentration of 6.14 kg. cm2 respectively. While the Seaweed affected the peel thickness as it was 1.00 mm and the fruit diameter was 6.67 cm. each fruit-1. The effect of hybrids, it was noticed that hybrid Rakan was significantly dominated in fruit peel thickness, fruit texture fruit toughness (0.86 mm) and (6.19 kg. cm2). The following characteristics of yield including fruit yield for each plant (2.05 kg. each plant-1, experimental unit total yield (41.00 kg), total yield of the green house (3.526 tones. green house), number of fruits per each plant (14.69 fruits. plant-1), and fruit average weight (137.67 gm). The hybrid Sadouf was dominated in the pH, which was 4.46.

This study was carried out to study some morphological parts of adult male of Liriomyza spp, including the antenna, the femur and the middle vein (Cu Al), as well as the shape of mines that larvae made them on the leaves. Results showed that there were two species of L.bryoinae on tomato crop and L.sativae on climbing beans crop, this was agreed with the molecular study that it was conducted using the RAPD Random Amplification of Polymorphic DNA based on the PCR technique to determine genetic variability of DNA that it was extraction from adults and pupae and obtained a quantity of it ranged from (35-556.9) mg and purity ranged between (1.7-2).
The RAPD markers were studied using 19 random primers, 13 of which showed a bands and 6 of them didn’t show any bands, the total number of bands loci were 53 loci, 23 of which were main bands and 30 were polymorphism and genetic analysis was performed based on these results. The genetic distance was found and lowest was (0.125) among adults and pupae of bean crop and higher distance was (0.323) the among the adults and the pupae of the tomato crop and the genetic distance between the tomato pupae and bean pupae was (0.185), according to this values the genetic relationship was found which was the tomato adult's species was independent and the genetic relationship between Adults and pupae have closest. Results showed that the pupae which were taken from the crops, there are two species of Liriomyza spp .
