Abstract
Pasture plots containing white and Caucasian clover were established on a summer-dry coastal Bay of Plenty farm and maintained under dairy grazing into a second year. Of soil dwelling pests, grass grub and Tasmanian grass grub populations increased most rapidly, with fewer present under Caucasian clover. Foliar insect feeding, with up to 26% loss of leaf area in white clover, was caused by lepidopteran larvae of Zizina labradus and indigenous species of Epyaxa. Epyaxa rosearia was the most significant defoliating insect on Caucasian clover. This is the first time that Epyaxa has been implicated as a pest of pasture legumes.
