Abstracts
Sphedanolestes minusculus Bergroth lays pale yellow eggs in batches.
Eggs are glued to each other and to the substratum with cementing material. The average number of eggs per female was 63.33 ± 21.77. The eggs hatch in 7.80 ± 0.41 days. The average developmental period from I instar to V instar was 48.43 ± 7.39days. The longevity of the male (80.16 ± 5.23) was shorter (96.77 ± 11.88) than that of the female. The preoviposition period was 12.55 ± 3.43 days and the male and female sex ratio was 1: 1.5. The
innate capacity of natural increase (rc) was 0.061 with a gross reproduction rate (mx) of 91.671 females per female. Mean length of generation (Tc) was 76.310 days. Redescriptions of adult and descriptions of egg and nymphal instars are given with illustrations. Predatory and mating behaviour exhibited sequential events as in other reduviids. Prey-deprived predators took less time
to approach, capture and pin the prey. Individuals of S. minusculus collected from three different ecological and geomorphological habitats viz., Olavakod tropical rainforest, Sunkankadai scrub jungle and Aralvaimozhi semiarid zone exhibited pronounced diversities in their oviposition pattern, hatchability, incubation and stadial periods, nymphal mortality, adult longevity and sex ratio. These diversities are considered a specially adapted biological function collectively called ecotypism.
