A METHOD FOR REARING NYSIUS ERICAE (HEMIPTERA: LYGAEIDAE), THE FALSE CHINCH BUG

The false chinch bug, Nysius ericae (Schilling), was reared successfully in clear polystyrene containers in the laboratory. Nymphs were fed hulled sunflower seeds and radish slices; adults were fed hulled sunflower seeds and seedlings of Brassica juncea mustard or B. napus canola. Eggs were laid in rolls of compacted cotton, stored at 5 ± 1°C, and brought out to room temperature for hatching.

INSECT VECTORS OF THE YEAST NEMATOSPORA CORYLI IN MUSTARD, BRASSICA JUNCEA, CROPS IN SOUTHERN SASKATCHEWAN

Eighteen piercing and sucking insects were identified as feeders on green pods of mustard crops, Brassica juncea (L.) Coss. in Saskatchewan. Of these, the false chinch bug, Nysius ericae (Shilling), Lygus spp., and the western damsel bug, Nabis alternatus Parshley, were found to carry the yeast Nematospora coryli Peglion internally. N. ericae was capable of transmitting this organism to seeds in healthy green mustard plants.
