Treatment led to dose-related reduction in the progeny number, survival and life span of the aphid, but wing development was not affected. With 2.0 μg/aphid or more of precocene II, all surviving offsprings shared precocious metamorphosis, but even with 0.5 μg/aphid, about 20% progeny showed such metamorphosis with 1.0 and 1.5 μg/aphid. Early nymphs tend to undergo precocious metamorphosis earlier, in the second moult.
