Abstract

Bract arrangement in the coconut fruit in relation to attack by the coconut mite Eriophyes guerreronis Keifer.

Abstract

Experiments carried out in St. Lucia in June-July 1984 showed that the arrangement of the bracts of growing coconuts influenced the pattern of attack by the mite Eriophyes guerreronis. Mite attack was worst where the bract was less tightly adpressed to the nut and where bracts overlapped each other. These findings suggested that physical space is necessary for E. guerreronis infestations to become established. The tightness of adpression may be an advantageous characteristic to select for when replanting.
