“…lb and ic). For P. snelleni, Machida (1934) reported n=13, but recently Hoshiba and Ono (1984) found n=30 in the male and 2n=60 in the female. We confirm here that the species certainly has n =30 and 2n =60.…”

“…In this connection, one of us (H. H.) and his co-workers have attempted recently to apply an air-drying technique for the chromosomal observation of a social wasp (P. snelleni), and revealed that the species has actually n=30 (Hoshiba and Ono, 1984). They listed in their paper the chromosome numbers of 12 social wasps, which ranged from n=9, 14,16,19,21,22,25,26,28,31, to 33.…”

The chromosomes of 21 species of Vespidae (consisting of 9 polistines and 12 vespines) were compared using an air-drying technique.The haploid number of the Polistinae ranged broadly (n=14, 22, 23, 26, 30, 31, and 34), while it was either n=25 or n=26 in the Vespinae. There were no karyological homologies (in terms of marker chromosomes) between these two subfamilies. Some phylogenetic relationships of social wasps were discussed, based on the karyological literature now available (32 species). We suggested that the three genera of Vespinae (Dolichovespula, Vespa, and Vespula) would have differentiated in two different ways from a common ancestor having 27 acrocentrics (n=27) by tandem fusion (the first genus with n=26) and by two centric fusions (the latter two genera with n=25).In the genus Polistes, the 5 subgenera (Fuscopolistes, Aphanilopterus, Megapolistes, Polistella, and Polistes) would have evolved independently toward increasing chromosome numbers since they started to separate from their ancestor having n=9-14.

“…The early males in Polistes wasps have been considered as a means to increase reproductive options for the worker caste (Strassmann, 1981;Suzuki, 1981Suzuki, , 1985Page et al, 1989). This can only be true if early males are haploid as was shown for P. snelleni by Hoshiba and Ono (1984). However, among species with CSD, diploid males surviving to adulthood are practically sterile, because they produce diploid sperm if they are fertile (Hung et al, 1974;Naito and Suzuki, 1991;Stouthamer et al, 1992).…”

Beyond helping the queen's reproductive function, the worker caste of Polistes wasps is expected to have an alternative reproductive strategy; to become a replacement queen, following copulation with early males that emerge along with the first brood workers. We analyzed genotypes and chromosome numbers of the early males in a natural population of P. chinensis antennalis. The frequency of earlymale-producing colonies within a population was 5.2 % (4 /77) in 1993 through 1995. The numerical sex ratios in the 4 colonies for the 3 years and another early male-producing colony in 1999 were 1:1. For one early-male producing colony in 1995, we genotyped 31 females and all 128 males. All 31 genotyped females out of 67 emerged females showed heterozygosity and 69 out of 128 genotyped males were heterozygous; the remaining 59 males were homozygous or hemizygous. The ratio between the number of females and diploid males in this colony was 67 :69, which is almost identical with one-to-one ratio.The cytological analysis of male chromosome for one early-male producing colony in 1999 revealed that the early males laid by a queen had 46 chromosomes, while worker laid males had 23. Our results revealed that the early males in this species are diploid males and eventually sterile. Secondly, the single locus complementary sex determination model is most plausible to explain the diploid male production in this species.

“…This suggests that W l l copulated with (at least) one EEM. The adaptive significance of the observed behavior in P. snelleni is not clear, however it may be favored by at least 2 facts: 1. existence of EEM (Hoshiba & Ono 1984); and 2. reproductive ability of the worker caste from the first brood. Both facts may relate to high mortality of hibernated foundresses in the solitary stage of this species (Suzuki 1985) as seen in P. exclamans (Strassmann 1981).…”
