Efficacy of some Entomopathogenic fungi in controlling filbert aphid, Myzocallis coryli Goetze (Hemiptera: Aphididae)

Author(s): Onur Aker, Celal Tuncer
Abstract: The Filbert Aphid is one of the pests of hazelnut growing area of Turkey. This study was carried out all fungal isolates caused significant mortality against first instar nymphs of filbert aphid after 2 and 5 days of conidial treatments at 18, 22 and 25°C temperatures under laboratory conditions. The results showed that first instar nymphs of M. coryli were more susceptible to the entomopathogenic fungi at 25 °C than 18 °C. M. anisopliae was highly and statically equally effective against nymphs of M. coryli at 18, 22 and 25 °C (86,0 %, 95,8 %, 100 %) after 5 days of conidial treatment. The other isolates; TR-05, TR-78.07 and TR-11 weren’t so effective as M. anisopliae on nymphs of M. coryli at 25°C (66,6 %, 53,6 %, 33,2 %). This study showed that isolate of M. anisopliae has virulent and highly potential for biological control on nymphs of M. coryli.
