“…A strong negative correlation between aphid populations and relative air humidity was verified by Cividanes and Cividanes (2010) and Ramos et al (2018) who indicate that this result may occur due to the pattern of variation in the population density of different species of aphids being linked to numerous factors that contribute to differences in their population dynamics. Honek (1985) confirms that aphid species are similarly influenced by meteorological factors and have similar characteristics in abundance and preference for favorable microclimates. However, it is not clear what the real influence of relative humidity is on the dynamics of these populations.…”

In the cotton crop (Gossypium hirsutum L.), there is a complexity of pests that appear systematically, thus significantly reducing crop yield; and their population fluctuation is strongly influenced by meteorological conditions that result in a greater or lesser density of these insects. Thus, this work aimed to evaluate the population fluctuation of insect pests with sucking feeding behavior in an area with and without irrigation in the cotton plant under second-harvest conditions. The experiment was developed at the State University of Maringá - Campus of Umuarama. In the experimental area, grid meshes of 10 × 10 m were demarcated, forming plots of 100 m², resulting in a total of 64 points in the irrigated area and 42 points in the non-irrigated area. The sampling points were demarcated in the center of each grid where three randomly selected plants were sampled. Samplings were carried out weekly, from 37 to 122 days after the emergence (DAE) of cotton, examining the aerial part of the plant, to observe the presence of aphids (Aphis gossypii), thrips (Frankliniella schultzei), and whitefly (Bemisia tabaci). The non-irrigated area provided the highest population peaks of whiteflies and thrips. On the other hand, the irrigated area had a higher incidence of aphids. However, with the increase in the population of ladybugs, the incidence of pests reduced significantly, showing the efficiency and importance of the control carried out by natural predators.

“…Different levels of antibiosis can be exhibited against a particular aphid species, as shown for Sitobion avenae (Fabricius) and M. dirhodum ( Sotherton and van Emden 1982 ), where differences in antibiosis between cultivars were generally smaller for M. dirhodum than for other species studied. Susceptibility to aphids also varies with the growth stage of the crop ( Kazemi and van Emden 1992 , Klueken et al 2008 ), so differences among studies can result from study differences in the phenological stage of the plant. In a comparison of ancient and modern varieties, the level of antibiosis in ancient varieties did not differ among the growth stages, whereas modern varieties showed a decreased level of antibiosis at ear emergence ( Sotherton and van Emden 1982 ).…”

“…They typically exhibit rapid development and a high reproductive rate due to parthenogenetic reproduction and telescoping generations ( Dixon 2012 ). Infestation by aphids negatively influences crop yield ( Papp and Mesterházy 1996 , Klueken et al 2008 ), so the control of aphid populations is necessary. Aphids feed on phloem fluids by piercing their stylets through the plant tissues ( Dixon 2012 ); thus, they are harmful not only due to the removal of the nutrients but also due to the release of salivary toxins into the plant, which cause necrosis of the tissues ( Nicholson et al 2012 , Kettles and Kaloshian 2016 ).…”

“…Screening cultivars and genetic lineages for resistance to aphids should be the first step of this process. Variability in resistance to aphids has been shown among different cultivars of a same host plant species, including cereals ( Papp and Mesterházy 1996 , Migui and Lamb 2004 , Klueken et al 2008 , Hu et al 2016 , Girvin et al 2017 , Ajmal et al 2018 , Chandrasekhar et al 2018 ). Ancient taxa of the genus Triticum , including einkorn ( Triticum monococcum L.), durum wheat ( Triticum turgidum (L.) ssp.…”

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.

Only few studies are available dealing with the relation between winter host density and spatial distribution and spring colonization of winter cereals by the host-alternating cereal aphid species Rhopalosiphum padi and Metopolophium dirhodum. Large-scale studies in climatically different agroecosystems in Germany from 2004 to 2006 revealed for R. padi and M. dirhodum larger spring/summer populations in landscapes with higher densities of winter hosts. A small-scale study was performed in winter wheat fields adjacent to a large hedge with several typical winter hosts plants, bird cherry (Prunus padus) and wild rose species (Rosa spp.) to indentify distance effects (0-8, 8-24 and 24-60 m). Weekly measurements of aphid density between May to July showed significantly higher densities of R. padi compared with those of other aphids. Statistical analysis (Tukey-Kramer test and regression analyses) revealed significant gradients from the hedge to the field centre for R. padi and M. dirhodum. In comparative studies, winged R. padi from winter and adjacent summer hosts were genotyped using four microsatellite markers. The results showed that individuals from a certain winter host were not genetically similar with individuals from neighbouring summer hosts; it, therefore, seems that winter host clones did not significantly contribute to population built-up in cereal fields over short distances. It could be concluded that on a regional scale, the density of sources for early migrants of R. padi is important for colonization intensity of surrounding summer hosts, but that the high local movement intensity and the relative small proportion of aphids that could be analysed in such tracking studies are blurring close spatial relations within short time periods.
