Abstract :
Effective Factors in the Use of Sex Pheromone Traps on the Capture Rate of Plutella xylostella Sana Akbari, Alireza Jalalizand*, Esmaeil Mahmoudi Department of Plant Protection, Faculty of Agriculture, Isfahan (Khorasgan) Branch, Islamic Azad University, Isfahan, Iran *Correspondence Author: Email: arjalalizand@gmail.com Received: 10 March 2020 Accepted: 2 June 2020 ABSTRACT Plutella xylostella L. which known as diamondback moth, is one of the most destructive pests of Brassica crops and causes qualitative and quantitative decrease of yield. Because of high reproductive rate, high capability of immigration and being resistance to many groups of insecticides, the control of this pests is difficult. Application of sex pheromone-baited traps is effectiveness non chemical methods to management of P. xylostella worldwide. This study was investigated the efficiency of color and height of pheromone traps on attraction of P. xylostella male moth in randomized complete block design with six treatments (yellow, green and transparent color with 70 and 120 cm height) with four replications. The results revealed that yellow trap with mean of 94.6 had the highest effect of moth attraction, and transparent traps with mean of 9.2 had the least P. xylostella trapping. In two different height of trap assay, the pheromone traps in 70 cm height had the greatest ability to attract the moth with mean of 55.7 insect. According to the results, the yellow pheromone trap at a height of 70 cm has the greatest effect in attracting the male species of the diamondback moth in cauliflower fields, which can be used to control of this pest.
