| Abstract:
A laboratory study on the effect of topical application of graded doses of JH analogues, Farnesyl Methyl Ether (FME), ZR 512, and MV 678 on the development and survival of H. antonii was conducted. Among the three analogues, FME moulted to sixth instar supernumerary nymphs, whereas the nymphs treated with ZR 512 and MV 678 at 1 μg and 1.5 μg moulted to sixth instar nymphs and adultoids. These post-moulted individuals had comparatively shorter life span than the normal individuals. The nymphs of H. antonii treated with the JH analogues showed varying degrees of developmental complexities. | |
