“…Commercial populations can lose genetic diversity through genetic drift (founder effects, bottleneck effects) and unintentional selection during mass production (Hopper et al 1993;Fernández and Nentwig 1997;Honda et al 2004;Hinomoto et al 2006). Since the traits related to commercial production generally show strong inbreeding depression (Falconer and Mackay 1996), the suppression of increased inbreeding in the commercial product will be an important issue.…”

The effectiveness of hybrid vigor, which can counteract deleterious effects of inbreeding in flightless Harmonia axyridis Pallas (Coleoptera: Coccinellidae), was investigated. First, we performed the reciprocal cross between two isofemale lines and compared survival and reproductive characteristics between isofemale and hybrid lines under laboratory conditions. The survival of one of the hybrid lines was significantly higher than that of the two isofemale lines. Early fecundity tended to be higher in the two hybrid lines than in the two isofemale lines. Second, we compared the effectiveness of control of Aphis gossypii Glover (Homoptera: Aphididae) between isofemale and hybrid lines by release experiments in greenhouses. The number of A. gossypii was suppressed in treatments in which two hybrid lines were released compared with those in which two isofemale lines were released. These results suggest that hybrid vigor is effective as a method for assuring the quality of flightless H. axyridis.

We developed 14 polymorphic microsatellite markers for the minute pirate bug Orius sauteri (Heteroptera: Anthocoridae), and tested them with five markers previously developed in O. strigicollis. Except at one locus from O. strigicollis, we obtained amplified fragments from a field population of O. sauteri. The number of alleles ranged from 2 to 14, and observed heterozygosity ranging from 0.000 to 0.900. The observed heterogeneity was negatively correlated with null allele frequencies. Linkage disequilibrium was detected in three pairs of loci. The 19 microsatellite loci were also tested for amplification and polymorphism in two congeneric species, O. minutus and O. strigicollis. Markers could be amplified at many loci, although null allele frequencies were higher in cross-species amplification than in intra-specific amplification. These microsatellite markers will be used in studies of genetic diversity in these species.

The role of founder effects on the genetic structure of the invasive bullfrog (Lithobates catesbeianaus) in China

RONO: 00Founder effects and genetic drift can reduce the genetic diversity and alter the genetic composition of introduced species during the processes of population establishment and spread. Thus, founder effects are of particular concern for introduced commercial populations (usually founded from few individuals) and for the natural populations they interact with. Bullfrogs were initially introduced in China for aquaculture purposes and escapes from farms have established many feral populations. Most of the bullfrog farms currently operative have been founded from a limited number of descendents from the original introductions, providing an excellent framework to elucidate the importance of founder effects and genetic diversity in the establishment and persistence of invasive species introduced for commercial purposes. We sequenced a region of the mitochondrial cytochrome b gene in 510 samples collected from feral and farm individuals across China and compared them to populations in their native range. Only two haplotypes (H43 and H7) were identified, and H43 identified in this study for the first time was present at high frequency in both feral and commercial populations. We show a significant difference in the relative frequency of the two identified haplotypes in commercial and feral populations, and suggest that sequential founding events are responsible for the emerging widely distributed new haplotype and the observed differences in genetic structure between bullfrog populations. Our findings indicate that lack of genetic diversity does not necessarily impair the colonizing ability of invasive species and highlight the potential threat posed by introduced commercial populations, given their unique genetic makeup.Peer reviewe
