Abstract: The tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of the most devastating pests. It has become a serious threat to tomato production. Five greenhouse trials were conducted on tomato crop during the season 2013 – 2014 for exploring control strategies by using the egg-parasitoid, Trichogramma achaeae Nagaraja and Nagarkatti (at a rate of 50 adults ̸ m2) compared with a microbial control ( using Bacillus thuringiensis at a rate of 2gm ̸ L). The effectivites of the insect predator, Macrolophus caliginosus Wagner (at a rate of 1 ̸ 2 adults ̸ m2) was also tested in a commercial tomato farm at El-Kanater district, Giza Governorte, Egypt, beside a combination of these three bioagents (T. achaeae, M. caliginosus and B. thuringiensis) at a rate of 25 adults ̸ m2, 1 ̸ 4 adults ̸ m2 and1gm ̸ L. The present study compared the efficiency of these methods for biological control of the tomato leaf miner, T. absoluta.The obtained results showed that all treatments were highly significant efficient in reducing T. absoluta mines during the present study, especially the three associated treatments.
Key words: Biological control; Tomato leaf miner " Tuta absoluta"; Trichogramma achaeae ; Bacillus thuringiensis; Macrolophus caliginosus; greenhouse; Egypt.
