“…On Niknezhad, aphids attained an intrinsic rate of natural increase of 0.381 as compared to 0.328 on Darab2, the least favourable variety. These results and the values are similar to those estimated for the R. padi reared on other host plants and wheat cultivars (Simon et al 1991;Asin & Pons 2001). The high performance of the aphid on Niknezhad mostly results from the longest adult longevity and the highest number of nymphs produced on this variety.…”

Taheri S., Razmjou J., Rastegari N. (2010): Fecundity and development rate of the bird cherry-oat aphid, Rhopalosiphum padi (L) (Hom.: Aphididae) on six wheat cultivars. Plant Protect Sci., 46: 72-78.Rhopalosiphum padi is a polyphagous species with a nearly worldwide distribution. Biological parameters of this aphid on six commonly grown wheat cultivars in the Fars province including Chamran, Darab2, Shiraz, Ghods, Marvdasht and Niknezhad were investigated at the two-leaf stage of wheat. The experiments were carried out at 24 ± 5°C, 65 ± 5% R.H. and a photoperiod of 14:10 h (L:D) in a greenhouse. The number of nymphs per female of R. padi was 62.05, 55.84, 49.89, 47.63, 42.76 and 40.65 (nymphs/female) on Niknezhad, Shiraz, Ghods, Marvdasht, Chamran, and Darab2, respectively. Also, the highest and the lowest r m values of this aphid were obtained on Niknezhad (0.381 per day) and Darab2 (0.328 per day), respectively. In addition, other population growth indices were estimated. In general, a high level of antibiosis in Darab2 compared with the other tested cultivars may decrease the population density of R. padi on wheat and also cause a suppression of cereal viruses (e.g. BYDV) and reduce the pesticide application to wheat fields of Iran.

“…Inter-clone variations are maintained over several generations between the Spanish and English R. padi clones (Pons & Tatchell, 1995), between insecticide-resistant and insecticide-sensitive clones of M. persicae (Eggers-Schumacher, 1983), between different pea aphid A. pisum clones (Via, 1991;McLean et al, 2009), and between different milkweed-oleander aphid A. nerii, clones from different host plant species (Zehnder & Hunter, 2007). Minor inter-clonal variations were observed for S. avenae clones from different locations (Simon et al, 1991;Khan, 2005;Khan & Port, 2008). However, the bird cherry-oat aphid has host-alternating behaviour, feeding on Rosaceae in winter and Graminae in summer (Glinwood & Pettersson, 2000), and this species could be expected to respond more easily to new host plants or varieties.…”

1. Maternal and offspring diet effects on life-history traits of the bird cherry-oat aphid Rhopalosiphum padi were tested on three wheat varieties. Using nine reciprocal combinations of wheat varieties, the effects of previous experience (maternal diet effect) on the aphid's response to resistant and susceptible varieties (offspring diet effect) were tested. Batis was susceptible, and Xiaoyan22 and Ww2730 were both resistant, but with different mechanisms.2. Aphids produced the most alatae in the treatments with the most resistant maternal diet variety Xiaoyan22. The fecundity (F) and intrinsic rate of increase (r m ) of these alatae were at their greatest in the most resistant offspring diet variety, but these traits were not influenced in the apterae.3. There were significant interactions in the alatae production and apterae life-history traits, such as r m , development time, weight gain, and mean relative growth rate, between the maternal and offspring diet varieties. The interactions in apterae responses between varieties, some of which were reciprocal, indicated phenotypic plasticity in these parthenogenetic aphids.4. Rhopalosiphum padi produced more alatae on the most resistant variety; the alatae would disperse and were more fecund. The growth responses of the apterae showed phenotypic plasticity to the different combinations of maternal and offspring diet varieties. The phenotypic plasticity would allow R. padi to better utilise the variable environments represented by the small wheat plots of different varieties in China.

“…For example, at 20ЊC on wheat, clonal r m mean values ranging from 0.23 to 0.28 were reported by Rispe et al (1996) and from 0.29 to 0.37 by Simon et al (1991). In the current study, clonal r m mean values varied from 0.41 to 0.47 under same conditions.…”

“…The effect of temperature and host plant on life history traits of R. padi clones (apterous and alate morphs) has been investigated previously (Villanueva and Strong 1964, Dean 1974, Elliot and Kieckhefer 1989, Simon et al 1991, Rispe et al 1996. These studies characterized R. padi clones by their geographic origin and/or by their ability to produce sexual forms.…”

Adaptive changes to local conditions are often thought to be required for successful invasions. However, there are also successful invasive asexual species that may have limited potential for evolutionary change. The bird cherry-oat aphid, Bhopalosiphum padi (L.) (Hemiptera: Aphididae), is thought to have been introduced in Australia 100 yr ago and is now an established pest of cereal crops. Here, we use mitochondrial DNA, cytochrome c oxidase subunit I, and nuclear microsatellites to characterize the genetic diversity in invasive R. padi. Asexual reproduction was detected and clonal diversity was low; with two multilocus genotypes, Rp1 and Rp2, dominating all populations. No geographic or host association was detected between the dominant genotypes on cereals but Rp2 was not found on sweet corn, Zea mays L., crops. The fitness of the predominant multilocus genotypes, Rp1 and Rp2, and an uncommon genotype, Rp26, were investigated on different host types (wheat | Triticum aestivum L. |, barley |Hordeum vulgare L. |, triticale | × Triticosecale Wittm. ex A. Camus. |, and sweet corn | Zea mays L. var. rugosa|) at two temperatures. Rp1 and Rp2 performed similarly on cereals and Rp26 performed poorly on all hosts, patterns that might explain field distributions and abundance of these clones. The results suggest that a high level of clonal diversity is not required for successful invasion and that host associations may develop despite low diversity.
