Some effects of heparin on Glossina palpalis palpalis (Robineau-Desvoidy) (Diptera: Glossinidae) fed in vivo

Abstract

AbstractFemale Glossina palpalis palpalis (R.-D.) produced larger puparia when they fed on live goats that were injected intravenously with 200 IU of sodium heparinate/day than when they fed on untreated goats or on heparinised goat blood in vitro. Heparin did not produce the same effects when guineapigs were the hosts. Puparia from flies that fed on untreated guineapigs were larger than those from flies that fed on untreated goats. Heparin had no effect on the life-span or fecundity of females that fed on goats or on the life-span of flies that fed on guineapigs. However, the fecundity of flies that fed on guineapigs injected with 500 IU heparin/kg was greater than that of flies fed on untreated guineapigs.
