Collier, T.R., Murdoch, W.W., & Nisbet, R.M. 1994 Egg load and the decision to host-feed in the parasitoid, Aphytis melinus.. Journal of Animal Ecology 63: 299-306.

Notes: This parasitoid attacks Aonidiella aurantii, a widespread pest of citrus; as predicted, host-feeding was associated with low, but non-zero egg loads.
