Estimation Of The Numerical Density Of The Pests Tutaabsolutaand Heliothisarmigeraon Some Tomato Cultivars Using Pheromone Traps

Abstract

The results of the study showed the efficiency of white and yellow pheromone traps in attracting males of T. absoluta and H. armigera on four cultivars of tomato (AMWAJ, NOUN, MAESTRO, BAYAN) in tomato fields located in the Dujail area of ​​Salah al-Din Governorate. The percentage of attraction in the month of March on the cultivars AMWAJ, NOUN, MAESTRO, BAYAN19.67, 19.09, 17.50, 17.17, respectively, in the white trap and 20.25, 17, 13.75, 11.42, respectively, in the yellow trap. In April, it reached 42.08, 41.83, 39.83, and 38.42, respectively, and 39.25, 28.08, 24.25, and 19.25, respectively, in the white and yellow traps. While the peak of the two pests in May was 43.50, 43.50 and 41.50, 38.17 and 40.83, 27.75, 25.42, 24.25 in the two traps, respectively. Then the number of pests decreased in June, reaching 20.49, 19.50, 18.17, 17.17, 22.58, 17.33, 14.42, 14.08, respectively.
