The effect of floral resources and mealybug honeydew on the longevity of Anagyrus fusciventris (Girault) (Hymenoptera: Encyrtidae), a parasitoid of both the longtailed (Pseudococcus longispinus Targioni Tozzetti) and citrophilus mealybugs (P. calceolariae Maskell) (Hemiptera: Pseudococcidae) in New Zealand, was investigated in the laboratory. A. fusciventris longevity was significantly increased by the provision of sugar solution, buckwheat (Fagopyrum esculentum) and alyssum (Lobularia maritima) flowers, and P. calceolariae honeydew compared with water alone. Female A. fusciventris provided with buckwheat survived 17 days longer than females provisioned with water alone.
