Abstract - The effect of the topical application of 135 ppm of the antijuvenoid, KK-42 on the 8 h old I, II, III and IV instar larvae of the silkworm hybrid, NB18 x NB7 were studied during winter and summer. The treatment in the II, III and IV instars induced trimoultism, and while the larval duration, cocoon weight, cocoon shell weight, fecundity and silk filament deniers significantly decreased, the filament length remained unchanged, except when the IV instar was treated.
