Aggregations of palm aphid Cerataphis
brasiliensis (Hempel) (Aphididae: Hemiptera) on the
unfurled spindle leaf of ‘Kalparaksha’ variety of
coconut, a selection from Malayan Green Dwarf, is
reported for the first time. C. brasiliensis has not yet
been observed from other coconut varieties, viz., West
Coast Tall, Chowghat Orange Dwarf, Chowghat
Green Dwarf, and Dwarf x Tall hybrids planted
in the research farm of Central Plantation Crops
Research Institute, Kayangulam, Kerala, India. Only
the apterous form of the palm aphid was noticed in
the semi-tall variety and a variety-induced emergence
of C. brasiliensis is indicated under natural conditions.
Due to the presence of two phoretic ant species,
no natural predator was observed in the aphid
colonies. Two sprays of dimethoate (0.05%) at an
interval of 15–20 days were effective in suppression
of the pest on Kalparaksha
