Least-squares means of two-generational fecunditya following topical exposure of M. persicae to sublethal concentrations of imidacloprid.

a24 h old nymphs were topically treated and thereafter reared on untreated potato leaf discs. Fecundity of each resulting adult was recorded every 2 days until it died. In the succeeding generation, 5 randomly selected 24 h old nymphs were tracked and fecundity of the resulting adults was recorded every 2 days until they died. G0 is initial generation, G1 is progeny of G0.bProgeny per adult data were log transformed before analysis. Backtransformed means are presented. Values followed by different letters are significantly different (LSD, α = 0.05). SEM values are not backtransformed.cMean total number of nymphs produced over four generations.
