Breeding and nymphal development of Lycosa coelestis L. KOCH

[摘要] References(3)Cited-By(3)The breeding and nymphal development of Lycosa coelestis L. KOCH were investigated by means of rearing under seminatural conditions. Three females successfully bred twice in their life. Breedings were carried out in underground nest. The mean number of progenies produced per female in each brood and its standard deviation were calculated to be 202.0±19.5 in the 1st brood and 76.7±25.5 in the 2nd. The mean total number of progenies produced per female in life was 278.7±35.3. The 2nd instar nymphs dispersed from mother's back on 19th July, 1995, developed to adult by late May-July of the next year. The number of molts required was 6-8 in the male and 7-9 in the female. Overwintering nymphs often dug underground nest and stayed in it.
