“…Especially remarkable is the case of Podisma pedestris, a flightless alpine grasshopper with two chromosomal races, one bearing an X0 and the other a neo-XY sex chromosome system (John and Hewitt 1970; Hewitt 1975; Mason et al 1995); however, this is not a polymorphism but a polytypism. A similar case has recently been described in the brachypterous grasshopper Podisma sapporensis (Kowalczyk et al 2008; Warchalowska-Sliwa et al 2008b). The frequency of the fusion in the different samples of S. dalmani was low, and there were no statistical differences among populations or among years.…”

Micro-Evolution in Grasshoppers Mediated by Polymorphic Robertsonian Translocations

This review focuses on grasshoppers that are polymorphic for Robertsonian translocations because in these organisms the clarity of meiotic figures allows the study of both chiasma distribution and the orientation of trivalents and multivalents in metaphase I. Only five species of such grasshoppers were found in the literature, and all of them were from the New World: Oedaleonotus enigma (Scudder) (Orthoptera: Acrididae), Leptysma argentina Bruner, Dichroplus pratensis Bruner, Sinipta dalmani Stål, and Cornops aquaticum Bruner. A general feature of these species (except O. enigma) is that fusion carriers suffer a marked reduction of proximal and interstitial (with respect to the centromere) chiasma frequency; this fact, along with the reduction in the number of linkage groups with the consequent loss of independent segregation, produces a marked decrease of recombination in fusion carriers. This reduction in recombination has led to the conclusion that Robertsonian polymorphic grasshopper species share some properties with inversion polymorphic species of Drosophila, such as the central-marginal pattern (marginal populations are monomorphic, central populations are highly polymorphic). This pattern might be present in D. pratensis, which is certainly the most complex Robertsonian polymorphism system in the present study. However, L. argentina and C. aquaticum do not display this pattern. This issue is open to further research. Since C. aquaticum is soon to be released in South Africa as a biological control, the latitudinal pattern found in South America may repeat there. This experiment's outcome is open and deserves to be followed.

“…Five studies in Table 2 are from Honshu Island (Japanese mainland), with much variation in the Orthoptera of Japan's 6852 islands which extend over 3000 km along the Pacific 'Ring of Fire' (Tojo et al 2017). Genetic diversity is hugely varied throughout the archipelago for Locusta migratoria (Tokuda et al 2010), Podisma sapporensis (Kowalczyk et al 2008), and Tetrigidae (Ichikawa 1994). The life cycle of widely distributed species such as L. migratoria is markedly different across the islands, diapause being influenced by latitude (Tanaka 1994).…”

There are few studies on the Orthoptera of the floodplains, paddy fields, and levee embankments of Japan’s riparian corridors. The research which has been undertaken indicates a relatively rich fauna (33% of Japan’s grasshopper species recorded) with endangered species (e.g. Eusphingonotusjaponicus) found on gravel floodplains, although diversity is restricted by forest cover and unfavorable land uses (e.g. agriculture). Management should focus on the alteration of levee mowing regimes to benefit orthopterans, and the control of invasive plant species and successional processes along river corridors, which appears to be important for grasshoppers of gravel substrates. Integrated Green Grey Infrastructure (IGGI) measures (levee terraces of Asteraceae plants) may enhance populations of Orthoptera and conserve declining plants such as Astertripolium in Tokyo. More research is required throughout Japan to accurately determine the orthopteran fauna and appropriate conservation measures, particularly along super levees and in paddy fields.
