Abstract
Chemical insecticides have been the main way to control synanthropic flies of medical and
veterinary importance; however, residuals of these products have become a factor impacting
on the environment, as well as the potential toxicological that they may cause damage to
humans and domestic animals. Phytochemical screening carried out with the aqueous
crude extract of Pouteria sapota (Jacq.) H.E. Moore & Stearn, Sapotaceae, leaves showed that
coumarins, reducing sugars, flavonoids and cyanogenic glycosides were its most abundant
metabolites. This study evaluated the activity of the crude aqueous extract of this plant on the
post-embryonic development of Chrysomya putoria. Larvae treated with 5, 10 and 25% extract
showed a decrease in the pupal period and in the newly-hatched larvae to adult period when
compared to the control groups. Larvae from the 25% extract group were the lightest (45.8
mg) when compared with the control group (46.5 mg). The larval and newly-hatched larvae
to adult stages were more sensitive to the leaf extract from P. sapota (5%) and the treated flies
showed the low viability (47.5 and 45.5% respectively). The results demonstrated that topic
treatment with P. sapota could alter C. putoria post embryonic development.
