Calliphora bioassay 20-

Ecdysteroids are generally regarded as not being able to penetrate insect cuticle readily [179], However, the rice stem borer, C. suppressalis, has a thin cuticle which allows ecdysteroids to penetrate when ligated last instar larvae are dipped into a methanolic solution of the test compound for 5 s [180], The proportion of pupated abdomina are assessed after 48 h. This assay is less sensitive than the Calliphora bioassay, but is easier to perform. Its main application has been in screening plant extracts for the presence of phytoecdysteroids [74],... [Pg.25]
