Accumulation and persistence of a nuclear polyhedrosis virus of the cabbage looper in the field

, : Accumulation and persistence of a nuclear polyhedrosis virus of the cabbage looper in the field. Journal of Invertebrate Pathology 20(2): 157-164

A nuclear polyhedrosis virus of Trichoplusia ni (Hb.) was applied to foliage of autumn-planted broccoli and cabbage plants in Maryland. Soil tests demonstrated that appreciable quantities of active virus accumulated in the upper 1 cm of the soil of plots sprayed with 10, 20 and 100 larval equivalents (LE)/acre as well as in unsprayed plots.

Full-length cDNAs encoding three forms of vitellogenin (Vg) were obtained from a liver cDNA library of estrogen-treated red seabream, Pagrus major. Two of the three Vg sequences had high homology with type-A and -B Vgs (VgA and VgB) of other teleo...
