  1. Note: L1, L2, L3, L4 refers to the first-to-fourth nymphal instars. n is number of individuals that completed the indicated stage. APOP = adult pre-ovipositional period; TPOP = total pre-ovipositional period. Data in the table are represented as mean ± SE. SEs were estimated using 100,000 bootstraps in two-sex MS chart. The means followed by similar letters in a row are statistically non-significant at the 0.05 level based on Tukey’s HSD multiple range test.
