Laspeyresia pomonella (L.), reared in 30-ml plastic jelly cups on artificial diets developed by Redfern, Howell, International Minerals and Chemical Corporation (IMC), Brinton, and Navon, were compared with moths reared on immature apples. Of the larvae reared on diets developed by Howell and by IMC, 47% developed into adults. Diets developed by Redfern, Brinton, and Navon produced 33%, 30%, and 28% adults, respectively. In comparison, 48% of the larvae reared on immature apples developed into adults. Male moths reared on apples were heavier than those reared on the artificial diets. Only the female moths reared on the IMC diet were comparable in weight to those reared on the immature apples. No significant differences were observed in the numbers of eggs laid, eggs hatched, or adult longevity.
