Abstract
Banana aphid, Pentalonia
nigronervosa (Coq.) is an important pest of banana and causing economic
damage due to transmission of Banana Bunchy Top Virus. A difference in the
infestation pattern of banana aphid has been recorded among the cultivars of
banana. In order to find out the role of host plant responses in the aphid
infestation, the host and host extracts were evaluated by behavioural assays.
Olfactometry studies of host indicated a maximum attraction of 40% in cvs
Karpuravalli and least preference was noted as 16.7% in Saba and Njalipoovan.
The solvent extracts demonstrated a maximum aphid attraction of 36.7% in cv.
Karpuravalli and a minimum attraction of 10% in Saba.
