摘要

Variation in sensitivity of Lepeophtheirus salmonis (Kroyer) to dichlorvos in static toxicity tests was recorded on salmon farms in Ireland. Five hour LC50s ranged from 60 to 202 #mu#g 1~(-1) at 15 deg C for five farms in Autumn 1991 and 76-151 #mu#g 1~(-1) at 10 deg C for four farms in Spring of 1992. Resistance ratios, calculated using the most sensitive sites as baseline, were low and ranged from 1.32 to 3.27 in 1991 and 1.28-1.98 in 1992. Repeat sampling on three farms in 1991 and 1992 also indicated short-term changes in sensitivity to dichlorvos within farms.
