Abstract

The coconut black-headed caterpillar (bhc) Opisina arenosella is one of the major pests of coconut palms causing considerable damage to coconut industry. As effective control has so far been elusive, the discovery of a successful method of control of this pest by systemic application of 'Soluneem', the first water soluble, non-toxic neem pesticide is reported. A single dose of systemic administration of the formulation containing 3000 ppm of azadirachtin A in aqueous solution at the base of the trunk translocated the biopesticide to the crown within 24 h. A highly significant reduction in the larval population, moult inhibition, reduction in adult emergence and malformation in the emerged adults was recorded in Soluneem-treated trees. The protection lasted for more than 120 days with no phytotoxic symptoms to the treated palms and Soluneem was safe for natural enemies.
