Abstract

The effect of five juvenile hormone analogues (JHAs) on the embryonic development of Panstrongylus megistus, a vector of Chagas’ disease, was studied. Four compounds, N-(2,5-dich-loropheny])-3,7-dimethyl-2-6-octadienylamine, N-(5-chloro-2-rnethylphenyl)-3,7-dimethyl-2,6-octadienylamine, 3,7-dimethyl-6,7-epoxy-1-(3,4-methylenedioxyphenoxy)-2-nonene, and 6,7-epoxy-3-ethyl-7-methyl-1-(3,4-methylenedioxyphenoxy)-2-nonene, which are potent JHAs for P. megistus, were effective in blocking eclosion when applied at 0.5 µg/egg to eggs during the first half of embryonic development. If these compounds were applied after the start of blastokinesis, then they were no longer active as ovicides. The possibility is raised that JHAs may be useful as control agents in complementation with insecticides which do not possess ovicidal activity.
