Thermal requirements for development and resource partitioning in aphidophagous guilds
European Journal of Entomology, 2005 The duration of the increase, peak and decline in abundance of the immature stages of sycamore and cereal aphids each year is ephemeral. These temporary resources are exploited by a sequence of aphidophagous insect predators. The temporal sequence in the

Biological control of cereal aphids in Michigan wheat
, 2014 Cereal aphids (Hemiptera Aphididae) are important pests of wheat and can cause yield loss through both direct feeding injury and indirectly by transmitting viruses.

Entomologia Experimentalis et Applicata, EarlyView.Using a model that translates qualitative prey detection data (presence/absence in predator gut contents) into quantitative predation rates, we estimate species‐specific diets of nine carabid species across three cropping contexts (wheat, sugar beet, and fodder beet) for five prey types.

Cereal Grasses – Host of Leaf Aphids in Boundary of Biological Field
Растениевъдни науки, 2013 The study was conducted in the spring of 2008 and 2009 in biological field of Institute of agriculture – Karnobat. In cereal crops and boundary around them in the spring, in conditions of organic farming are established to harm four types of leaf aphids

An effective molecular approach for assessing cereal aphid-parasitoid-endosymbiont networks
Scientific Reports, 2017 Molecular approaches are increasingly being used to analyse host-parasitoid food webs as they overcome several hurdles inherent to conventional approaches.

Damage effects of cereal aphids in wheat
Netherlands Journal of Plant Pathology, 1981 Laboratory and field studies on aphid damage in wheat are described. Both direct and indirect effects of aphids on the behaviour of the crop were studied. In the laboratory a clear effect of honeydew and yeasts on photosynthesis was found. This effect could not be demonstrated under field conditions, since even at yield loss levels of 700 kg ha−1 the ...

Ecological Entomology, EarlyView.Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

The depth and breadth of capitalism at the Cape
The Economic History Review, EarlyView.Abstract Limited liability company legislation was introduced to the Cape Colony in 1861. An amendment in 1892 led to wider adoption, expanding and diversifying the capital market. Using novel data from the Cape Joint Stock Archive between 1892 and 1902, this paper examines who invested, where capital flowed, and how these patterns shaped firm outcomes
