“…It is usually classified as antixenosis (plant attractiveness to herbivores), antibiosis (herbivore performance), and tolerance (compensation of the plant for herbivore feeding) ( Smith 2005 ). Like other plants, cereals have natural mechanisms of resistance to pests, including traits such as a leaf morphology ( Roberts and Foster 1983 , Papp and Mesterházy 1993 , He et al 2011 , Dixon 2012 , Saska et al 2020 ) and secondary plant metabolites ( Niemeyer et al 1992 ; Elek et al 2013 , 2014 ) that can be affected by aphid feeding ( Chandrasekhar et al 2018 ) and play important roles in the resistance against aphids.…”

Yield losses caused by pests, including aphids, can be substantial in cereals. Breeding for resistance against aphids is therefore desirable for enhancing the economic and environmental sustainability of cereal production. The aim of our study was to reveal the degree of antibiosis against Metopolophium dirhodum (Walker) (Homoptera: Aphididae), in four cultivars of spring wheat, Triticum aestivum L. (‘Alicia’, ‘Odeta’, ‘Libertina’, ‘Astrid’), and two cultivars of emmer, Triticum turgidum ssp. dicoccum (Schrank ex Schübler) Thell. (‘Rudico’, ‘Tapiruz’) (both Poales: Poaceae) under controlled laboratory conditions. Using age-stage, two-sex life table, we quantified responses of M. dirhodum to each cultivar and to project population growth. The spring wheat and emmer cultivars varied in their suitability to M. dirhodum. The cultivar most susceptible to M. dirhodum was the emmer cultivar ‘Rudico’; the projected population size of M. dirhodum on this cultivar was one order of magnitude larger than those on other cultivars. The most resistant cultivar was the spring wheat cultivar ‘Libertina’. Since emmer is commonly used as a gene source for breeding T. aestivum, we advocate that care be taken to avoid the transmission of genes responsible for suitability to aphids from emmer to T. aestivum.

“…We apply age-stage, two-sex life table theory ( Chi and Liu 1985 , Chi 1988 , Chi et al 2020 ) to assess the population development of aphids. This approach has proven robust for evaluating aphid population dynamics ( Saska et al 2016 ), including the level of antibiosis among cereal cultivars ( Saska et al 2020 ).…”

Time point- and plant part-specific changes in phloem exudate metabolites of leaves and ears of wheat in response to drought and effects on aphids

et al. 2022

Alterations in the frequency and intensity of drought events are expected due to climate change and might have consequences for plant metabolism and the development of plant antagonists. In this study, the responses of spring wheat (Triticum aestivum) and one of its major pests, the aphid Sitobion avenae, to different drought regimes were investigated, considering different time points and plant parts. Plants were kept well-watered or subjected to either continuous or pulsed drought. Phloem exudates were collected twice from leaves and once from ears during the growth period and concentrations of amino acids, organic acids and sugars were determined. Population growth and survival of the aphid S. avenae were monitored on these plant parts. Relative concentrations of metabolites in the phloem exudates varied with the time point, the plant part as well as the irrigation regime. Pronounced increases in relative concentrations were found for proline, especially in pulsed drought-stressed plants. Moreover, relative concentrations of sucrose were lower in phloem exudates of ears than in those of leaves. The population growth and survival of aphids were decreased on plants subjected to drought and populations grew twice as large on ears compared to leaves. Our study revealed that changes in irrigation frequency and intensity modulate plant-aphid interactions. These effects may at least partly be mediated by changes in the metabolic composition of the phloem sap.

“…There are many studies showing that the host plants, A. gossypii, affect the development, reproduction and population parameters (Alizadeh et al 2016;Polat-Akköprü 2018) The interaction of the relationship between insect and plant is linked to different resistance types like antibiosis (high death rate, short lifespan), antixenosis (effects on behavior and not selection or tolerance) [the ability of the plant to tolerate the pest (Li et al 2004 Many factors that arise from plants affect the performance of the pest. The characteristics of the host plant, such as its biochemical content (secondary metabolites, jasmonic acid, abscisic acid and salicylic acid), morphological and physical structure (tissue hardness, trichomes and cell wall thickness, color) and nutrient quantity, affect the population parameters of the pest (Wilkinson & Douglas 2003;Smith 2005;Saska et al 2020). Polat-Akköprü et al (2015 stated that plant fitness often depends on the biochemical content of the host plants can help explain the factors affecting the population growth of the pests.…”

In this study, population growth parameters of Aphis gossypii Glover (Hemiptera: Aphididae) on five different melons [Cucumis melo Linnaeus (Cucurbitaceae) cultivars (Balin, Çıtırex, 221 F1, Gediz, Yusufbey)], which are commonly grown in Turkey, were investigated in laboratory experiments. Life table parameters were estimated according to age-stage and two-sex life table theory. The results showed that A. gossypii developed more successfully on the Gediz cultivar due to the higher intrinsic rate of increase (0.5042 1/day), the finite rate of increase (1.6557 1/day) and the shorter mean generation time (8.161 days) than the other cultivars. Ecological pest control against aphids' use of resistance or less favourable host plant cultivars is considered one of the significant components of pest management. The findings obtained in this study can be used in the pest management program designed for the aphid.
