ISOLATION OF BACILLUS MEGATERIUM FROM APHIS POMI (HOMOPTERA: APHIDIDAE) AND ASSESSMENT OF ITS PATHOGENICITY H.M. Aksoy and S.K. Ozman-Sullivan Ondokuz Mayis University, Faculty of Agriculture, Department of Plant Protection, 55139 Samsun, Turkey
SUMMARY
Bacillus megaterium isolates were recovered from the green apple aphid, Aphis pomi De Geer, collected from apple trees in the Samsun province of Turkey.
