Determinants of host selection for species of Aphytis (Hymenoptera: Aphelinidae), parasites of diaspine scales

John L. Baker

Hilgardia, 1976, vol. 44, issue 1

Abstract: Host selection behavior in entomophagous insects is a series of reflex responses to physical and chemical stimuli. It was known that the host selection process for Aphytis, parasites of armored scales, utilized the stimulus of a water-soluble chemical contained in the scale cover and that physical features were unimportant. It was unknown whether the adult could exercise host discrimination and restrict oviposition to host species that were suitable for progeny development.
