Abstract

The coconut mite, Eriophyes guerreronis Keifer in St. Lucia: yield losses and attempts to control it with acaricide, polybutene and Hirsutella fungus.

Abstract

Chemical (with vamidothion), physical (with sticky material) and microbial (with Hirsutella thompsonii) control measures were tested against Eriophyes guerreronis [Aceria guerreronis] on coconuts in St. Lucia. None of the treatments resulted in control of the mite, which caused up to 31.5% loss of potential yield. The major scope for yield increases did not lie with control, but rather in improved agronomic practices, which, if allied to replanting with improved and mite-resistant cultures, could at least double present yields.
