Text Appearing Before Image:
17 ( I ) As an egg parasite of the Gipsy Moth, Anastatus bifasciatus a chalcid, takes first pilace. One drawback is its low powers of distribu- tion, about 250 feet per year, and its power to parasitize only the upper layer of eggs in the mass which is usually three layers in thickness, so that artificial dispersion becomes necessary.
Text Appearing After Image:
Anastatus bifasciatus, adult female. An egg parasite of the Gipsy Moth, greatly etilarged (from Howard) (2 ) The egg parasite, Schedius Kuvanae, also a chalcid ob- tained from Japan, does not give promise of being able to withstand the winter conditions.
