Abstract

In St. Vincent, arrowroot leaf-roller Calpodes ethlius (Cramer) is the major pest of arrowroot (Haranta arundinacea), and causes a reduction in the starch yield of the rhizomes. During the period 1982' - 1984, it was found that the pest was more numerous between July and November, the infestation was slightly lower in the North of Dry River and the two varieties 'Banana' and 'Creole' grown in the island were equally susceptible to the pest. The two larval parasites, Ardalus (~Elachertus) sp. and Bracon sp., (despite their secondary parasites) are the most important biocontrol agents which keep the pest under reasonable control. The 'Jack Spaniard" PoUstes cinctus cinctus , Polybia occidentalis grenadensis, Anoplius sp. and Prionyx thomae play a significant role in the reduction of the pest
