The biology of Apanteles medicaginis Muesebeck (hymenoptera: Braconidae)

William W. Allen

Hilgardia, 1958, vol. 27, issue 18

Abstract: Apanteles medicaginis Muesebeck is an important parasite of the alfalfa caterpillar, Colias philodice eurytheme Boisduval. This small braconid parasite oviposits inside the early host instars and the larva completes its development by the time the Colias caterpillar reaches the late third or fourth instar. At maturity the parasite larva emerges from the caterpillar, spins a small yellowish cocoon and pupates. The wound inflicted by this emergence causes death of the host caterpillar in a very short time. Since the caterpillars are killed before they can feed heavily, this parasite can effectively prevent damage to alfalfa.
