ABSTRACT
The results showed that super Marimond variety was the most susceptible. The average density of white fly population ( eggs, nymphs and adults ). Reached 3.61 egg/16 cm², 2.72 nymph/16 cm² and 2.14 adult/leaf respectively. The highest density of populations during the months of year were 6.37 egg/16 cm² 4.22 nymph/16 cm² and 3.9 adult/leaf respectively in variety of super Marimond in October which accompany with increasing of Tomato yellow leaves virus (T. Y. L. C. V.) It reached 15.1% and so observed the percentage of infection increased with progressive in age of plant. In comparison with among the sticky traps the results showed that the trap of atrarat sticky was best in the field and laboratory experiments, the percentage of hunt 32.33% of adult in laboratory while in field was 29.54% and 33.16% in months October and November respectively. The Second traps which covered engine oil it reached 30.46% and 30.86 in both of months respectively. The result showed that cordyx trap was 21.4% in November. The results were also revealed that the interaction between Evisect 20 SP insecticide and sticky traps with used of two spray of Evescet gave a best protected from infection during the growth of crop especially in the peak of adults activity in October and November months. The use of third spray of pesticide and sticky traps gave a sure protected the plants of tomato from the infestation. The population density of insects were 0.26 egg/16 cm² ,0.2 nymph/16 cm² and 0.13 adult/leaf with engine oil traps while in atrarat traps were 0.22 egg/16 cm², 0.16 nymph/16 cm² and 0.08 adult/leaf compression with other treatment. The cultivate of the cucumber crop with tomato crop in the level of ten plants of cucumber in rose reduced the infestation. The average of adult became 1.05 adult/leaf but with fifteen plants of cucumber crop in rose increased the density of the pest to 2.6 adult/leaf and distribution of yellow leaves curl virus disease, the percentage of disease about 14.6% in Tomato crop.
