Özet

Pathogenicity of five commercial bioinsecticides; Bio-Catch (Verticillium lecanii), Priority (Pgecilomyces.fumosoroseus), Bio-Nematon (Paecilomyces lilacinus), Bio-Magic (Metarhizium anisopliae) and Bio-Power (BeauVeria bassiana) was evaluated against Aphis fabae under laboratory conditions at 20 and 25 C. LT50 values for V. lecanii; P. fumosoroseus; P. lilacinus, M anisopliae, B. bassiana at 20 degrees C were 2.33, 2.49, 2.67,.2.24 and 2.60/days, respectively while at 25 degrees C they were 2.03, 2.18, 2.28, 2.04 and 2.77/days, respectively. LT90 values at 20 degrees C were 4.49, 5.94, 6.46,5.01 and 6.64, while at 25 degrees C, they were 5.03, 5.40, 6.68, 5.18 and 7.42, respectively. On the 7th day, mortality rates were approximately 100% at all treatments. Insignificant differences were found among the tested products as well as between the two temperatures stddied (P=0.989, P>0.05).
