Klappentext

Excerpt from Bioassay of Acephate-Treated Foliage on Three Instars of the Douglas-Fir Tussock Moth

Pnw - 241, 7 p. Pacific Northwest Forest and Range Experiment Station, Portland, Oregon.

Field application of acephate was made on 16-acre plots of Douglas-fir and grand fir at 1 lb active ingredient per acre. Bioassays of first, second, and third instars of the Douglas-fir tussock moth indicated that acephate caused the highest mortality on first instar larvae tested 1 day after treatment. Mortality decreased with older instars and with time after treatment. General mortality trends were similar for the three instars.
