“…The aphids collected from Córdoba and Santa Fe were subsequently analysed for mt (mitochondrial) DNA polymorphisms by Martínez et al, (1993) andCastro (1994). The values of their genetic distances (Nei, 1987) were similar to those found by Powers et al, (1989) for B and C biotypes in the USA. Nonetheless, mtDNA haplotypes of Argentinean and Spanish clones showed no relationship with biotype characterization (Martinez et al, 1993;Castro 1994), which accords with recent results published by Anstead et al (2002).…”

Abstract. The aphids Schizaphis graminum (Rondani) (greenbug) and Diuraphis noxia (Mordvilko) (Russian wheat aphid, RWA) were collected from several localities in Argentina and Southern Chile. Clones were established from aphids collected at each location. The host preferences were studied in free choice tests. Biotypes were characterized on the basis of aphid antibiosis and host plant tolerance. The production of sexuals was assessed under natural conditions, from March to November in 1997-2001, at La Plata (34°55' S, 57°57' W). The greenbug distribution ranged from 24°40' to 43°28' S, and was bounded between isothermals 18-20°C and 8-10°C, and isohyets 400-600 mm and greater than 1200 mm. The aphids at all localities were collected from a wide range of cultivated and wild hosts. The biotypes in ten out of thirty-four populations were identified. One population was obligatorily parthenogenetic, the remainder cyclically parthenogenetic. No correlation was found between the region they came from and the period required for the induction of sexuals. RWA was found between 26°50´ and 43°28´S, bounded by the isothermals 20-22°C and 8-10°C, and isohyets 400-600 mm and 2000 mm. In Chile, this aphid was only found in Osorno County, which lies on isothermal 8-10°C and is bounded by the isohyets 1000 mm and 2000 mm. Only a few RWA genotypes (clones) produced sexuals irrespective of the host they were collected from, period of the year, region, current host, or the day length and average temperature of the rearing conditions. For the first time, RWA was found infesting cultivated as well as wild oats in South America. At low latitudes, populations of both aphid species were found only infesting wild Sorghum halepensis (L).

“…For example, the major portion of nucleotide diversity (1.97 per cent) within Drosophila simulans is ascribed to differences among three (generally) spacially isolated cytoplasmic races; only 0 to 0.046 per cent variation exists within each cytotype (Baba-Aissa et a!., 1988). Non-Drosophila examples are Schizaphis graminum (Powers et a!., 1989) and Glossina morsitans (Trick & Dover, 1984). An intermediate example (Afonso et a!., 1990 Given the widespread occurrence of common haplotypes in Ontario and New Mexico, it seems more likely that present-day populations stemmed from more than one refugium.…”

Intraspecific mitochondrial DNA variation in the migratory grasshopper, Melanoplus sanguinipes

1992

Restriction fragment analysis of mitochondrial DNA (mtDNA) was used to examine genetic variation and population structure of the migratory grasshopper, Melanoplus sanguinipes. The total DNA of 89 individuals was digested with 10 restriction enzymes and probed with three cloned EcoRT fragments representing the entire mitochondrial genome (total length 16.1 kb). Five endonucleases revealed polymorphism, yielding 12 haplotypes in combination. Nucleotide diversity indices (6) between haplotypes ranged from 0.18 to 0.92 per cent with an average value (pr) of 0.27 per cent, a comparatively low figure that possibly reflects a history of chronically small population numbers prior to the species' colonization of a suitable habitat engendered by agricultural settlement. Little, if any, differentiation was evident among locations or between prairie and parkland regions, areas spanned by a colour trait dine. Selective forces with respect to the latter must, therefore, be sufficiently powerful to withstand the attenuating effects of widespread gene flow, implied by the mtDNA data.

“…However, polymorphisms are typically detected at a few loci (Wool ci' at., 1978;Loxdale et at., 1985;Rhomberg et aL, 1985;Steiner et at., 1985b) and in several aphid species no variation has been found (May & Holbrook, 1978;Tomiuk & Wohrmann, 1980;Loxdale et a!., 1983;Beregovoy & Starks, 1986). Substantially more genetic variation has been detected using mitochondrial DNNrestriction fragment length polymorphisms (mtDNA-RFLPS) (Powers et at., 1989;) and DNA fingerprinting probes (Carvalho et at., 1991;Shufran et a!., 1991). Recently, genetic polymorphisms revealed by RAPD-PCR (Random Amplified Polymorphic DNA amplified by the Polymerase Chain Reaction) (Williams et at., 1990) have been demonstrated in several species of aphids and aphid parasitoids (Black etat., 1992).…”
