Abstract
Abstract The chloronicotinyle insecticide imidacloprid, BAY NTN 33893 240FS, was evaluated to determine its potential effectiveness against WCR adults. A topical bioassay was conducted using formulated insecticide. Six concentrations ranging from 0.002 to 1.12% (AI) were mixed in water and topically applied (1.0 μl/insect) to the ventral abdomen of WCR adults obtained from a colony at the Northern Grain Insects Research Laboratory. Insects were also treated with water only (untreated check). On each treatment date, 40 individuals were treated per concentration (total tested/date = 280). After application of the insecticide, beetles were placed into 100-mm petri dishes containing artificial diet and held in the laboratory at 24° C and 50% RH. The numbers of mori-bund and alive insects were determined at 1, 2,4, and 24 hours after application. The bioassay was repeated four times. Data were analyzed using an analysis of variance (SAS Institute, 1988) and the POLO-PC Probit procedure (LeOra Software, 1987).
