Efeitos do extrato aquoso de Ipomoea carnea subsp. fistulosa sobre o desenvolvimento de larvas de Chrysomya albiceps (Wiedemann, 1819) (Calliphoridae: Diptera)

Plants of the genus Ipomoea are known to cause lethal poisoning in farm animals. However, little is known about the effects of their toxins on veterinary and forensic invertebrates. This study aimed to determine the effect of an aqueous extract of Ipomoea carnea subsp. fistulosa at different concentrations on larval development time and size of immature Chrysomya albiceps (Wiedemann, 1819), a species of forensic importance in Brazil. C. albiceps L1 larvae were subjected to three treatments: control (ground beef only), 80 g ground beef mixed with 40 mL of plant extract) and 80 g of ground beef mixed with 80 mL of plant extract. Larval development time until the pupal phase was statistically longer in the 40 and 80 mL extract treatments in relation to the control. The total length of the control larvae was significantly longer than with the extract treatments. The results suggest that the toxins present in I. carnea subsp. fistulosa slow the development of C. albiceps larvae.
