Table 2 Size variation of the complete egg (sqrA and Perimeter) and of the operculum (Centroid size)

From: The modern morphometric approach to identify eggs of Triatominae

Mean Variance Mean Variance Mean Variance
R. ecuadoriensis L 1.07 0.0019 4.51c 0.038 0.67 0.0012

  1. Abbreviations: R Rhodnius, L Loja Province, M Manabí Province, T Triatoma, P Panstrongylus, sqrA, mean square root of the area within the egg boundary
  2. Note: All pairwise comparisons of mean sqrA were significant (permutation test, 1000 cycles, P ranging from P = 0.015 to P < 0.0001). The perimeter showed significant differences between three groups: (a) P. chinai, (b) P. howardi, T. carrioni and R. ecuadoriensis Manabí and (c) R. ecuadoriensis Loja (permutation test, 1000 cycles, P < 0.0001). The only significant difference of variance was observed for sqrA between T. carrioni and the Loja sample of R. ecuadoriensis (permutation test, 1000 cycles, P = 0.002). The mean size of the operculum was significantly different between all comparisons (permutation test, 1000 cycles, P < 0.0001). The variance of the operculum size was not significantly different between groups
