Precocene II terminated pupal diapause in the bollworm Helicoverpa armigera as 20‐hydroxyecdysterone did, whereas juvenile hormone analog ZR‐515, cyclic adenosine monophosphate (CAMP), and 5‐hydroxytryptamine (5‐HT) did not. The results indicate that precocene II affects diapausing pupae in the similar way as what was found in the prepupae of the aphid parasitoids, Aphidius matricariae Haliday and Praon volucre Haliday (Hymenoptera: Aphidiidae). It is suggested that precocene II may affect different kinds of termination of diapause in insects.
