Abstract

Juvenile hormone analogues (JHA) were fed in an artificial diet to laboratory reared Porthelria dispar (L.) larvae. The analogues used were: I: Stauffer R-20458; 1-(4′-ethylphenoxy)-6,7-epoxy-3,7-dimethyl octene. II: Altozar®. III: Hoffmann-La Roche Ro 8-5497; 10,11-epoxy-3,7,11-trimethyl-1-(2-propynyloxy)-2,6-tridecadiene. For JHA I and II mortality occurred primarily during the larval and pupal stages with overall EC50 values from 0.19 to 0.43 p.p.m. in the diet. JHA III was not toxic. The log-probit dose–mortality curves showed low slopes. Morphologic aberrations in treated larvae and pupae were observed.
