Hoz M.T. De La
The length and mortality percentage for each stage of the post-embryonic development of male and female Selenaspidus articulatus are presentes under environmental conditions at 25,5+ 1,7 degrees and 75,6+ 6,7% of relative humidity. The post-embryonic development of both sexes are different, not only compared to number of molts and morfology, but also in relation with the length of each stage. The first female instar delays 11,24+ 1,36 days and the second 13,76+ 2,11 days. The first male instar delays 11,89+1,26 days, the second 10,42+ 2,44 days and the third 5,17+ 2,01 days. The mean total length of the female post-embrionary development was 25,03+ 2,64 days and that for the male was 27,17+ 2,25 days. The growth after molting delays 5,55+ 1,54 days in both female instars and 6,09+ 1,29 days for the first male instar; the end of the growth in the second male instar is imperceptible. Sex can be recognized in the female 2,90+ 1,37 days after the first molt and in the male, 3,28+ 1,51 days after the same molt. The percentage of nymphs attached to the leaves was 57,75% and mortality was 15,24% between the attachment and the first molt, 20,12% during the second instar and 5,49% during the third instar.
