Abstract: The bird cherry-oat aphid Rhopalosiphum padi L. (Homoptera: Aphididae) is one of the main pests in a number of crops in the semiarid Pampas of Argentina. In the present study, the effect of different host plants, including Triticum aestivum L., ×Triticosecale Wittm., Hordeum vulgare L., Hordeum distichum L., Avena sativa L., and Secale cereale L. on biological parameters of R. padi L. was studied in the laboratory at 24 ± 1 °C, 65 ± 10% RH and a 14:10 photoperiod. Longevity, intrinsic rate of natural increase (r m), net reproductive rate (R0), mean generation time (T), doubling time (DT), and finite rate of increase (λ) of the bird cherry-oat aphid on the different cereal crops were estimated. Differences in fertility life table parameters of R. padi among host plants were analyzed using pseudo-values, which were produced by Jackknife re-sampling. Results indicated that beer barley might be the most suitable food for R. padi due to greater adult longevity (20.88 d), higher fecundity (41 nymphs female-1), higher intrinsic rate of natural increase (0.309 females female-1 d-1), lower doubling time (2.24), and lower nymphal mortality (22.2%). Therefore, it can be concluded from the present study that R. padi prefers beer barley for fast and healthy development over other cereal crops. El áfido Rhopalosiphum padi L. (Homoptera: Aphididae) es una de las principales plagas de numerosos cultivos de la región semiárida pampeana de Argentina. En el presente trabajo se estudió el efecto de diferentes cereales incluidos Triticum aestivum L., ×Triticosecale Wittm., Hordeum vulgare L., Hordeum distichum L., Avena sativa L. and Secale cereale L. sobre los parámetros biológicos de R. padi en laboratorio. Se estimaron longevidad, tasa intrínseca de crecimiento natural (r m), tasa neta de reproducción (R0), tiempo generacional medio (T), tiempo de duplicación (TD), y tasa finita de incremento (λ) del pulgón de la avena en diferentes cereales. Las diferencias de los parámetros biológicos de R. padi entre los distintos cultivos fueron analizadas utilizando pseudovalores con la técnica de Jackknife. Los resultados indican que la cebada cervecera podría ser el cultivo más preferido por este áfido debido a la larga longevidad (20,88 d), la alta fecundidad (41 ninfas hembra-1), la alta tasa de incremento natural (0,309 hembras hembra-1 d-1), el corto tiempo de duplicación (2,24 d) y la baja mortalidad ninfal (22,2%). De los resultados obtenidos podemos inferir que R. padi tiene una mejor performance sobre la cebada cervecera que sobre el resto de cereales utilizados en este tr

Abstract: 麦长管蚜Sitobion avenae (Fabricius),麦二叉蚜Schizaphis graminum (Rondani)和禾谷缢管蚜Rhopalosiphum padi (Linnaeus)虽然都取食小麦,但其取食部位、传毒能力均有差异。利用EPG研究了3种麦蚜在同一寄主植物上的取食行为,结果显示:(1)禾谷缢管蚜在取食过程中G波出现的时间最早,G波总的持续时间和每次刺探G波的平均持续时间都明显长于麦长管蚜和麦二叉蚜。麦长管蚜第1次E1波的时间、E1波总的持续时间和每次刺探E1波的平均持续时间都明显比麦二叉蚜和禾谷缢管蚜要长。麦二叉蚜E2波总的持续时间和每次刺探E2波的平均持续时间都明显长于麦长管蚜和禾谷缢管蚜。表明3种蚜虫各自拥有不同取食策略。禾谷缢管蚜比其它两种蚜虫需要更多的水分和无机盐,麦长管蚜通过分泌大量唾液增大对食物的利用率,麦二叉蚜通过增加韧皮部取食时间以满足对营养的需要。(2)刺探过程中麦二叉蚜pd波出现的次数为(51.97±7.82)次,高于麦长管蚜的(44.73±4.52)次和禾谷缢管蚜的(32.99±4.22)次。麦二叉蚜pd波Ⅱ-2和Ⅱ-3亚波的时间最长,禾谷缢管蚜最短,三者之间差异达显著水平。表明与其它两种麦蚜相比,麦二叉蚜在取食过程中口针与细胞间的接触频率更高,与细胞内获毒和传毒相关的Ⅱ-3波和Ⅱ-2波持续时间更长,增加了获毒和传毒的几率,是其传毒能力最强的机理。

Asian Journal of Plant Sciences , 2003,
Abstract: Research was conducted to determine the effect of Coccinellid predators and plant phenology on the population dynamics of Macrosiphum rosaeiformis Das (Aphididae: Homoptera) in the University of Arid Agriculture Rawalpindi from 5th November 2000 to 15th April 2001. The rose aphid population was peaked in the month of January 2001. Rose aphid population was negatively correlated with Coccinellids predators. Rose aphid preferred the tender portion of plant especially flowers and flower buds causing deformation and discolouration. The resistance of four varieties i.e. Ice White, Sarabande, Lake Como and Iceburg (Rosa indica: Rosaceae) was studied against rose aphid. None of variety had resistance against rose aphid to significantly reduce their population.

Abstract: rhopalosiphum rufiabdominalis (sasaki) is an insect of world-wide distribution that damages irrigated rice. from september, 2004 to february, 2005, nymphs and adults of this aphid were collected in several host weeds of rice farms in alegrete, quaraí and uruguaiana, located in western of state of rio grande do sul, and restinga seca, in central region of this state, brazil. the insect was found in the root of andropogon bicornis (west indian foxtail), echinochloa colona (jungle rice), oryza sativa (volunteer rice and red-rice), paspalum sp. (paspalum) and soliva pterosperma (lawn burweed).

ZooKeys , 2012, DOI: 10.3897/zookeys.166.2387
Abstract: The new species Rhopalosiphum chusqueae Pérez Hidalgo & Villalobos Muller, is described from apterous viviparous females caught on Chusquea tomentosa in Cerro de la Muerte (Costa Rica). The identity of the species is supported both by the morphological features and by a molecular phylogenetic analysis based on a fragment of the mitochondrial DNA containing the 5’ region of the cytochrome c oxidase 1 (COI) and on the nuclear gene coding for the Elongation factor-1 alpha (EF1α). The taxonomic position of the new species is discussed. An identification key to the Aphidinae species living on plants of Bambusoideae (Poaceae) is presented.

Abstract: The development, survival rate, reproduction and biological parameters of the corn leaf aphid, Rhopalosiphum maidis (Fitch), on five corn cultivars were evaluated at 25°C under laboratory conditions. The corn leaf aphid had a longer nymphal developmental time of 4.99, 4.98, 4.73, 4.46, and 5.60 day of Ada9516, K. Arifiye, PrimerG626, Pegaso and TTM815, respectively. The corn leaf aphid reared on K. Arifiye had the highest fecundity (69.65 offspring/aphid). The lower percentage survival rates were observed on TTM815 than that of the others. Net reproductive rate (Ro) was lowest (67.35 offspring/aphid/generation) on TTM815. The intrinsic rate of increase (rm) was lower on TTM815 than that of the other corn cultivars. TTM815 showed resistance to the pest.

Abstract: the objective of this study was to evaluate effects of total rainfall, mean temperature, natural enemies, chemical composition of leaves, levels of nitrogen and potassium on leaves and density of leaf trichomes on attack intensity of thrips palmi karny (thysanoptera: thripidae) and aphis gossypii (glover) (homoptera: aphididae) on plantations of the eggplant (solanum melongena) in two regions of minas gerais, brazil. higher numbers of a. gossypii/leaf and t. palmi/leaf were observed in plantations of this eggplant in the municipalities of vi?osa and guidoval, respectively. guidoval had a rainy and hotter weather than vi?osa. t. palmi was almost positivelly correlated with rainfall (r= 0.49, p= 0.0538) while a. gossypii seemed to be more affected by mean temperature (r= -0.31; p= 0.1134). higher number of aphids in eggplants in vi?osa than in guidoval could be explained by the higher number of natural enemies such as adialytus spp. (hymenoptera: braconidae), cycloneda sanguinea (l.) and exochomus bimaculosus mulsant (coleoptera: coccinellidae) and chrysoperla spp. (neuroptera: chrysopidae) in this municipality. however, only adialytus spp. was significativelly correlated with aphid populations. higher number of t. palmi in eggplant plantations of guidoval than in vi?osa could be due to the absence of its possible eulophidae parasitoid in the first municipality. the spiders were significativelly correlated with this pest in both municipalities.
