“…Hundreds of young and adult female Liocheles australasiae (Fabricius) were collected from a maleless population Koike, 1984, 1985;Makioka, 1992aMakioka, ,b, 1993 on Iriomote Island, one of the Ryukyu Islands, Japan, in 1994Japan, in , 1995Japan, in , 1996Japan, in , and 1998. They were collected by forceps from spaces under the bark of fallen trees in the daytime.…”

“…This has not yet been explored. Makioka & Koike (1984) and Makioka (1992Makioka ( , 1993) demonstrated that female Liocheles australasiae (Fabricius, 1775) reared in isolation in the laboratory, produced five successive generations in seven years. No spermatozoa were found in any region of the female reproductive system, males do not occur in these populations, and populations reproduce by thelytokous parthenogenesis (Makioka & Koike, 1985;Yamazaki & Makioka, 2005).…”

“…Only when females are raised in captivity as in Liocheles (Makioka, 1992(Makioka, , 1993 is it possible to obtain this information In addition, in order to calculate RP an estimate of longevity is needed. However, longevity can only be estimated (in prep.…”

Abstract. Most scorpion species are iteroparous, breeding more than once during their life. Some of these species are parthenogenetic. The other reproductive strategy (RS) semelparity, when scorpions breed only a single time during their life, is rare and has been documented only once. The mass allocated by the female to produce either a litter or a single offspring is the reproductive allocation (RA). It is difficult to calculate RA since the difference in female mass before and after parturition is difficult to obtain. In addition, the litter size is hardly ever accurate because of maternal cannibalism. An attempt was made to calculate RA in Nebo hierichonticus (E. Simon, 1872). Based on litter size, on breeding frequency and on longevity of the female, it is possible to estimate the reproductive potential (RP). These aspects of scorpion reproduction are reviewed and the difficulties involved in this study are discussed.

“…In most species of scorpion (outside the tropics) there is a single discrete, annual breeding season (Matthiesen, 1970;Makioka & Koike, 1985;Makioka, 1992). Scorpions inhabiting tropical regions do not breed at a particular time of the year and produce several broods annually.…”

Abstract. Although scorpions are an ancient group their method of reproduction is rather complex and poorly studied. This review aims at clarifying some of the aspects of their reproduction that are important for understanding the reproductive ecology of other arthropods, including insects. The following aspects of scorpion reproduction are discussed and reviewed: mating, insemination, fertilization, gestation, parturition and birth. The onset of gestation and its duration are difficult to determine as both depend on the time of fertilization, for which there are no accurate estimates. There are only a few records of the time between birth and emergence of a larva from the maternal envelope in apoikogenic scorpions, which is important for a better understanding of ovoviviparity. All these questions are important as the answers will greatly enhance our understanding of the population ecology of scorpions in terms of the recruitment rates of cohorts and their chances of survival.
