Abstract
Bioactivity of the latex from Parahancornia amapa (Apocynaceae) on the development of Rhodnius nasutus (Hemiptera,
Reduviidae, Triatominae) under laboratory conditions. The aim of this study was to verify the effects of the methanolic
fraction of the latex from Parahancornia amapa (Apocynaceae) (PALAM) on individuals of the species Rhodnius nasutus Stål
(Hemiptera, Triatominae). Many of the insects treated with the substance presented deformities and these may interfere in the
feeding and possibly hinder the reproductive capacity. They also presented significant mortality during the molt when compared
to the control group, noting a gradual increase in mortality. The treated insects also presented delayed nymphal development (5th
instar) and higher adult longevity.
