Abstract

The onion thrips, andattack manyvegetablecropscausinggreateconomic damageto them esp < span>ecially onioncrop < /span>s.Four entomopathogenic fungi (EPF) formulations, including isolates of Beauveria bassiana (Bals.) and Metarhizium anisopliae (Metsch.) were used against T. tabaci. Two wettable powders and two emulsions that have been containing B. bassiana and M. anisopliae, (WPB, WPM, EB and EM respectively) in this study were treated in comparison to a botanical-insecticide Azadiractin (Oikos 3.2 % EC) and a chemical insecticide Thiamethoxam (Actara 25 WG) as a recommended pesticide against Thrips tabaci. Fieldtrialswereconductedduring the 2021 season,at the experimental farm, Faculty of Agriculture, Moshtohor, Banha University, Toukhdistrict,Qalubiya Governorate and in plant protection institute farm, Doki, Giza Governorate.Our results showed that all the tested formulations of EPF and Oikos began to kill insects throughout the period from the 3rd day and the reduction percent increased as the period increased to the 10th day, while, Actara kill insects after 24 hours. After 10th days of treatment, the average general effects were 76.968, 74.53, 73.185, 72.087, 70.4 and 68.625 for EB, WPB, Actara, EM, Oikos and WPM, respectively. These results revealed that fourB. bassiana and M. anisopliae formulations were effective against T. tabaci in field conditions, especially B. bassiana formulations. So we can suggest that these formulations of entomopathogenic fungi should be applied in integrated pest management (IPM) against T. tabaci.
