Collection were conducted in six Egyptian governorates (Giza - Fayoum - Aswan - Albehera - Alkaliobia {u2013} Ismailia) from February 2011 to the end of november 2012 with rate of infestation ranged between 5% - 70% The preferred host of T. absoluta is tomato, it can also attack the eggplant. During survey studies, three predators were recorded associated with T. absoluta (nesidiocoris tenuis, macrolophus caligonsus and chrysoperla carnea).

Biological studies were conducted on T. euprocitidis, T. achaeae and Ch. carnea using Tuta absoluta eggs, and on Macrolophus caliginosus using Ephestia keuhniella eggs. Assessment of T. achaeae for the control of T. absoluta in tomato greenhouses, three release doses (25, 50 and 75 parasitoids / m²) were tested during two year experiment 2011 / 2012 and 2012 / 2013 at Berkash Giza |
