Spinosad (<em>Saccharopolyspora spinosa</em>) , BSA3 (<em>Beauveria bassiana</em>) , Mycotal (<em>Lecanecillium muscarium</em>) and using chemical insecticide Hatchi hatchi 15% EC against Potato Leafhopper <em>Empoasca fabae</em> on cowpea. the rate of nymphs and adults population was significantly reduced in treatments Hatchi hatchi (1.8,3.7), Mycotal (3.3,4.7)  , Spinosad (3.3,5.6)and BSA3 (3.7,6.4) compared with control (6.4,9.2) respectively. The results was showed that superiority of spinosad treatment in  mortality of nymphs  of <em>E. fabae</em> to (44.76%) with significant differences from other treatments followed by mycotal (41.31%), and then BSA3, which amounts to (29.77%). Mycotal was showed high  mortality in the adults of <em>E. fabae</em> to 50.6%  then  Spinosad (39.49%) and BSA3 (30.15%) . This study shows that the use of one of these biocides in the field may be sufficient to reduce the numbers of nymphs and adults during the study season.</p>}, journal={JOURNAL OF ADVANCES IN BIOLOGY}, author={Khamas, Nihad Aziz and Salim, Hussein Ali and Mutney, Hussein Ali and Hormoz, Ferial Bahgat}, year={2018}, month={Dec.}, pages={2277–2282} }
