“…The values of demographic and life table parameters of A. pisum on FL plants ( Fig. 2; Table 3) were typical for this species on P. sativum under preferable environmental conditions and similar to the values reported by other authors (e.g., Legrand and Barbosa 2000;Goławska 2010;Joschinsky et al 2015). Likewise, the probing and feeding behaviors of the pea aphid (Table 4) were representative for the species under given favorable conditions on peas (e.g., Kordan et al 2012).…”

Light is primary source of energy and also plays signaling and regulatory roles in developmental processes and defense responses of plants. The aim of the study was to determine the performance, settling preferences, probing, and feeding behavior of Acyrthosiphon pisum on Pisum sativum grown in complete darkness (NL), with light at minimum level required for photoperiodic reaction (LL) and under full-light (FL) conditions. The effect of A. pisum infestation on metabolic status and defense responses of peas under FL, LL, and NL conditions was also determined. The population growth rate was limited on LL and NL pea plants as compared to FL plants. The reproductive period of aphids on LL and NL plants was eight times shorter than on plants growing in FL. In contrast to aphids on FL plants, the majority of A. pisum rejected LL and NL plants during settling. Aphid probing activities were not impeded on LL and NL plants but the probes were significantly shorter than on FL plants and consisted mainly of non-phloem activities. The analysis of tolerance of P. sativum to A. pisum showed that on FL plants, the number of aphids was nearly five times higher than on plants growing in low light (LL) at the end of the 2-week experiment but the tolerance index of FL plants was higher than that of LL plants. The contents of chlorophyll a, chlorophyll b, carotenoids, saccharides, and phenolics and the activity of b-D-glucosidase were notably lower in LL and NL plants than in FL plants. The increase in light intensity from complete darkness to the minimum level required for photoperiodic reaction did not stimulate evident changes in the measured plant biochemical parameters. These trends occurred in aphid-free (AF) and aphidinfested (AI) plants. However, under FL conditions, b-Dglucosidase activity and the content of saccharides were lower in AI plants than in AF plants. No differences in the measured plant biochemical parameters between AI and AF plants occurred under LL and NL conditions. The low b-D-glucosidase activity and low content of phenolics in the light-deprived plants that have reduced ability to photosynthesize show that under the biotic stress of aphid infestation plants invest in supporting basic metabolism rather than in defense against herbivores.

“…Several reports have been published about the effects of host cultivars on pea aphid life histories (Bieri et al 1983;Goławska and Łukasik 2009). Considerable research has been conducted on the demographics of the pea aphid (Hutchison and Hogg 1984;Zeng et al 1993;Legrand and Barbosa 2000) as well as on the effect of different plant species and cultivars and plant morphology on pea aphid development Mackay 1990, 1991;Kaakeh and Dutcher 1993;Sandström 1994;Sandström and Pettersson 1994;Kordan et al 2008). Edwards et al (2003) found that the growth, survival, and fecundity of three aphid species on Fabaceae plants were suppressed on resistant varieties as compared to susceptible varieties.…”

“…These substances seriously affect insect population processes, aphid behaviour, physiology and metabolism and as a result reduce aphid population on a resistant plant. Many intrinsic characteristics of plants such as nutritional value, secondary chemicals and morphology can influence the fecundity, growth and survival of insect herbivores (Montllor 1991;Legrand and Barbosa 2000).…”

Abstract:The performance of the pea aphid, Acyrthosiphon pisum Harris (Homoptera: Aphididae) was studied on several Fabaceae species including: pea (Pisum sativum), broad bean (Vicia faba), alfalfa (Medicago sativa), bean (Phaseolus vulgaris) and red clover (Trifolium pratense). Alfalfa, bean and red clover were less accepted by the pea aphid than pea and broad bean. The pea aphid fed on the alfalfa, bean and red clover showed longer pre-reproductive, and shorter reproductive and post-reproductive periods. Alfalfa, bean and red clover also shortened and decreased fecundity of the pea aphid. Mean survival of the pea aphids fed on red clover and bean plants was reduced in comparison to pea aphid fed on pea and broad bean. The other studied population parameters: intrinsic rate of natural increase (r m ), net reproduction (R 0 ) and mean generation time were also reduced in the case of the pea aphid on alfalfa, red clover and bean. The study of aphid development and reproduction demonstrated that pea and broad bean are suitable host plants for A. pisum while alfalfa, red clover and bean are not. It is likely that the rejection of alfalfa, red clover and bean by A. pisum was caused by chemical factors in these hosts.

“…For this we used the equation r m = 0.74(lnM d )d, developed by Wyatt & White (1977), and used by others (Sandström 1994, Legrand & Barbosa, 2000, Leather & Dixon, 1984, where d is mean prereproductive time in days, M d is number of offspring during a period equal to d. The factor 0.74 is a correction factor. We measured M d as number of nymphs produced per aptera during the d first days of reproduction.…”

Three experiments were conducted to study how nutrient content of the host plant, Petunia axillaris hybrida Villm. Grandiflora Group, affects the performance of Macrosiphum euphorbiae (Thomas) (Homoptera: Aphididae). Aphid performance was analysed in relation to plant nutrient levels and the ratio of nitrogen to potassium (N/K). Phosphorus (P) had a positive effect on several parameters of aphid performance. Both P and K were associated with a short development time but a strong correlation between P and K content made it impossible to detect their relative importance. In one experiment aphid performance was significantly lower on unfertilised plants with low N content, suggesting a positive effect of N. A high N/K ratio did not, in general, increase aphid performance. The complexity of plant nutrient content on aphid performance suggests that not only nutrient levels but also ratios of nutrients must be considered.
