Abstract
Topical application of insect growth regulators to freshly moulted sixth-instar larvae ofSpodoptera litura prevented their differentiation into pupae and resulted in the formation of a larval-pupal mosaic and of supernumerary larvae. The degree of the juvenilizing effect was dose-dependent; the doses above 20 μg produced the greatest effect, with 13.3 — 23.3% short-term mortality of treated caterpillars.
