Century Dictionary and Cyclopedia
- n. Any insect of the family Chalcididæ or the family Proctotrypidæ which lays its eggs in the eggs of other insects. The chalcidid subfamilies Trichogramminæ and Mymarinæ seem to be exclusively composed of egg-parasites, and the same may be said of the proctotrypid subfamily Scelioninæ. The genus Hadronotus is a parasite of the eggs of Heteroptera. H. rugosus is described by Howard from eggs supposed to be those of the cotton-stainer, Dysdercus suturellus. See cut under
“The Leptus-form larva of Julus, with its strange embryological development, in some respects so like that of some worms, points in that direction, as certainly as does the embryological development of the egg-parasite”
“Polynema, another egg-parasite, which lays its eggs (one, seldom two) in the eggs of a small dragon fly, Agrion virgo, which oviposits in the parenchyma of the leaves of waterlilies.”
“The development of Ophloneurus, another egg-parasite, agrees with that of Platygaster and Polynema.”
“This egg-parasite passes its early life in the eggs of Pieris brassicæ, and two or three live to reach the imago state, though about six eggs are deposited by the female.”
“The last egg-parasite noticed by Ganin, is Teleas, whose development resembles that of Platygaster.”
