Biological control of a non-honeydew producer mediated by a distinct hierarchy of honeydew quality

open access: yesBiological Control, 2013
Parasitoids feed commonly on honeydew. However, a high content of energy reserves in honeydew-fed parasitoids does not imply an increase of their fitness because honeydew may be relatively unsuitable. Herein, we studied the feeding behavior and fitness (longevity and fecundity) of a parasitoid, Aphytis melinus DeBach (Hymenoptera: Aphelinidae), which ...
