标题：THE SUSCEPTIBILITY OF THREE TOMATO CULTIVARS AND THE EFFICACY OF THREE CHEMICALS IN CONTROLLING THE BROAD TOMATO LEAFMINER, TUTA ABSOLUTA (MEYRICK) (LEPIDOPTERA: GELECHIIDAE) IN THE REGION OF MIDDLE JORDAN VALLEY IN JORDAN
摘要：The tomato leafminer, Tuta absoluta, is a serious pest of tomato that was introduced into Jordan in 2010.Thus, this study aimed to investigate the susceptibility of three tomato cultivars and the efficacy of three insecticides in controlling the immature stages and in developing an IPM program. Experiments were conducted in Al-Karamah Al Balqa governorate in the middle of Jordan valley during 2013 to 2015. The first tested experiment was the susceptibility of Dafnis, Newton and Shams cultivars to T. absoluta. The second tested experiment was Avaunt®, Belt® and Phytomax® for controlling the pest on cultivar Dafnis. The third test was the least susceptible cultivar and the most effective insecticide in developing an IPM program and compared it to conventional control. The IPM program used cultivar Dafnis which was the least susceptible cultivar to T. absoluta in the Alkarameh location. The total number of larvae was the lowest in cultivar Dafnis compared to Newton and Shams (1786, 2252, 2421) in Al Karamah. The insecticide Avaunt® was also used which was the most effective insecticide. The total number of larvae was the lowest using Avaunt® compared to Belt®, Phytomax® and control (216, 498, 757, 895) in Al Karamah.
