Abstract
Field trials with snap bean, varieties Paulista, Bronco, Xera and Savana were conducted at four cultivation dates (1998-1999) at Ismai­lia Governorate to study the impact of foliar application of insecticides, Reldan, Evisect S, Vertemic and Neemazal on the broad bean leaf miner Liriomyza trifolii (Berguss) and the yield components of snap bean. Re­sults indicated that among the insecticides, Reldan was the most effec­tive in controlling the leaf miner and produced the highest quality and quantity of green yield, it was followed by Evisect S, Vertemic and Nee­mazal, respectively, in different sowing dates. Considering the varieties, Paulista was more tolerant to the infestation of L.trifolii followed by Bronco, Xera and Savana. Considering the date of sowing during the winter season, the lowest population density of the leaf miner was achieved when snap beans were sown in 20/10/1998.
