The quality of aphids as food for generalist predators: implications for natural control of aphids
European Journal of Entomology, 2005 The paper reviews existing data on the food quality of cereal aphids for generalist predators. Data are presented for spiders, harvestmen, carabid and staphylinid beetles, cockroaches, ants and one species of bird.

Native Regiella Endosymbionts Provide Strong Parasitoid Protection With Limited Impacts on Fitness and Virus Transmission in Myzus persicae. [PDF]
Environ MicrobiolNative Regiella insecticola in Myzus persicae provides strong protection against parasitoid wasps but imposes only modest reproductive costs and does not affect virus transmission. Despite stable vertical and horizontal transmission, these effects alone do not explain the low natural prevalence of **Regiella** in field populations.

Detoxification of Gramine by the Cereal Aphid Sitobion avenae [PDF]
Journal of Chemical Ecology, 2009 Secondary metabolites play an important role in host plant resistance to insects, and insects, in turn, may develop mechanisms to counter plant resistance mechanisms. In this study, we investigated the toxicity of gramine to the cereal aphid Sitobion avenae and some enzymatic responses of S. avenae to this alkaloid. When S.

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Agriculture, 2017 In Transylvania, the evolution of wheat insect pests is strongly influenced by the ecotehnological conditions, by climate change and current technology (Malschi, 2009 Malschi et al., 2015). The paper presents the dynamics and importance of the main pests

Barley yellow dwarf virus infectivity of cereal aphids trapped at two sites in Victoria
, 1981 Alate cereal aphids, Rhopalosiphum padi, R, maidis and Macrosiphum miscanthi avenae, caught in suction traps at Horsham and Burnley for two successive years (1977-78), were tested individually for infectivity with barley yellow dwarf virus (BYDV).

Life, 2022 Previous studies have shown that vector-borne viruses can manipulate the host selection behavior of insect vectors, yet the tripartite interactions of pathogens, host plants and insect vectors have been documented only in a limited number of pathosystems.
