Nc. Elliott et al., INFLUENCE OF 4 APHID PREY SPECIES ON DEVELOPMENT, SURVIVAL, AND ADULTSIZE OF CYCLONEDA-ANCORALIS, The Southwestern entomologist, 19(1), 1994, pp. 57-61
The effects of aphid prey species on immature development and survival
of Cycloneda ancoralis (Germar) were studied. Cycloneda ancoralis lar
vae fed Aphis gossypii Glover and Aphis helianthi (Monell) had longer
developmental times than those fed Diuraphis noxia (Mordvilko) or Lypa
phis erysimi (Kaltenbach). Development times did not differ significan
tly between sexes. Percent survival from egg hatch to adult eclosion d
id not differ significantly among larvae fed different aphids. The wei
ght of newly eclosed adults differed significantly among C ancoralis f
ed different aphids and also differed between sexes; females weighed m
ore than males. Individuals fed A. gossypii weighed least, while those
fed L erysimi weighed most. The total number of aphids eaten by C anc
oralis larvae differed significantly among individuals fed different a
phid species. Larvae fed A. gossypii consumed more aphids than larvae
fed other aphid species. Larvae fed D. noxia consumed the fewest aphid
s.
