Abstract:In paired-cage studies, husk feeding by Cryptophlebia illepida (Butler) resulted in an average twofold increase in nut drop 66 d after introduction compared with nuts that were not fed upon. This data suggested that nut immaturity could be related to Cryptophlebia spp. feeding. Field tests demonstrated that the proportion of nuts with husk damage was related to the proportion of nuts which were immature in a sample. My data show that the effect of Cryptophlebia feeding on macadamia is underestimated when only direct damage to the kernel is assessed.
