. Topical application of the juvenile hormone mimic, Altosid, to Hippodamia convergens (Guérin‐Méneville) (Coccinellidae) stimulated a significant increase in long‐term flight behaviour in both males and females. Altosid treatment also stimulated ovarian development in females. Topical application of precocene II to H.convergens inhibited flight activity in treated animals of both sexes for about 10 days. Altosid treatment to precocene‐treated beetles significantly increased their migratory behaviour over that of precocene‐treated or acetone‐treated controls. These results indicate that juvenile hormone stimulates migratory flight behaviour in this species along with reproductive development. It is likely that the hormone serves to coordinate migration with reproduction in the young adult.
