Abstract
Tuta absoluta is the most important insect pests which pose a serious threat in tomato production in many countries. The effectiveness of entomopathogenic fungi (Beauveria bassiana) as safe prospects for the biological control of tuta absoluta in tomato crops and the safe use of this fungus as a biological control where no negative effects on the surrounding environment and on the farmers and consumers health promote many studies to estimate the susceptibility of T. absoluta to B. bassiana. The development of safe approaches to control tuta absoluta would be facilitated through an information on this pest and data for the safe use of entomopathogenic fungi (B. bassiana) as efficient biological control programs. The current study will encourage us to find solutions more realistic and safer to humans and environment-friendly for pest management. Evaluation the activity of B. bassiana spores as a biological control agent was carried out in this study using liquid-semi solid fermentation techniques and t, the entomopathogenic B. bassiana fungus could be caused larvae mortality up to 95% compared to chemical treatment 88%.
