Triflumuron Effects on the Physiology and Reproduction of Rhodnius prolixus Adult Females

Table 7

Effect of oral or topical TFM treatment on carcass chitin contents of Rhodnius prolixus adult females. Control insects were fully engorged on defibrinated rabbit blood only, whereas experimental insects were fed with blood containing 3 μL TFM/mL blood (oral) or directly received 3 μL TFM on the dorsal surface of the abdomen immediately after feeding (topical). Insects were kept for 5 days and dissected and then carcasses were submitted to chitin quantitation. Values are means ± SEM of at least three experiments with 3 insects each. Asterisk marks denote differences between control and experimental groups (unpaired -test, ; ); hashtag denotes differences between mated and nonmated groups ().
