Résumé
Tuta absoluta is a devastating pest of tomato. It is originated from South America. This pest is crossing boarders and devastating tomato production both protected and open fields. The infestation of T. absoluta also reported on potato, Eggplant and common beans Recently, T. absoluta considered to be a serious threat to tomato production in Mediterranean region. This research is conducted in Al-Arroub Agricultural Research Station, at the southern highlands of Palestine during 2011-2012 and had three objectives, which were : to monitor the annual flight activity and seasonal abundance of the T. absoluta ; to record the host susceptibility and rate of infestation of T. absoluta, and to investigate the susceptibility various tomato cultivar under open field and greenhouse condition ; and to investigate the effect of some common sense control measure as alternatives to chemical insecticides. Throughout this research, tomato ; eggplant and pepper plants were found to be susceptible to T. absoluta infestation both in open field and in greenhouse cropping system. In addition, the highest rate of infestation recorded on tomato, followed by eggplant and the lowest was on pepper plants. Furthermore, all investigated tomato cultivars were susceptible to T. absoluta infestation both in the open field and in the greenhouses. For the second objective, results show that, two peaks of flight activity of T. absoluta were recorded in the open field, the 1st peak was recorded at late June and the 2nd peak was at late July. Furthermore, the flight activity of T, absoluta that were recorded in the open field was higher than that recorded in the greenhouses. As for the last objective, both Petroleum oil and B.t treatments were significantly higher in their efficiency for control of T. absoluta in the open field. Meanwhile, Mass-trapping of T. absoluta using sex pheromone sticky traps was able to suppress the T. absoluta population in the greenhouse plantation. In conclusion, further study is recommended to be done on rate of MassTrapping Technique that might be applied in open field as well as in the greenhouse cropping system.
