Prociphilus (Meliarhizophagus) fraxinifolii (Riley, 1879) (Hemiptera: Eriosomatidae) is an alien species in Europe that has been spreading quickly there. This paper presents the origin and current occ...
Length of prematurity period in wheat cultivars determines maximum cereal aphid abundance
flowering time Metopolophium dirhodum population Rhopalosiphum padi Sitobion avenae spring wheat
2016/9/2
Maximum aphid numbers on wheat are positively related to the length of the period elapsed from immigration to the population peak. We predicted that maximum abundances on late maturing cultivars would...

Insecticidal Activity of Chitosans of Different Molecular Weights and Chitosan-metal Complexes against Cotton Leafworm Spodoptera littoralis and Oleander Aphid Aphis nerii
arthropod pests larval mortality biopolymer
2015/3/9
As an alternative to synthetic pesticides, chitosan has received much attention as a biopolymer active against
some agricultural pests. The, insecticidal activity of chitosans of four molecular weig...
Fecundity and Development Rate of the Bird Cherry-oat Aphid, Rhopalosiphum padi (L) (Hom.: Aphididae) on Six Wheat Cultivars
Rhopalosiphum padi wheat cultivars biological parameters
2015/3/5
Rhopalosiphum padi is a polyphagous species with a nearly worldwide distribution. Biological parameters of this
aphid on six commonly grown wheat cultivars in the Fars province including Chamran, Da...
Comparison of Field Population Growths of Three Cereal Aphid Species on Winter Wheat
Metopolophium dirhodum Rhopalosiphum padi Sitobion avenae population dynamic pest monitoring winter wheat
2015/1/30
Population growths of three aphid species colonising winter wheat stands, Metopolophium dirhodum, Rhopalosiphum padi and Sitobion avenae, were analysed by regression method. The calculations were base...
Biochemical Characterisation of α-Amylase in Two Aphid Species, Aphis fabae Scopoli (Hemiptera: Aphididae) and A. gossypii Glover (Hemiptera: Aphididae)
aphids gel assay starch
2015/3/11
We identify and characterise α-amylases of the two aphid species, A. fabae and A. gossypi. To do this, α-amylases of
the two insect species were extracted and their activities were determined using ...

2009/1/12
The greenbug, Schizaphis graminum (Rondani), and bird cherry-oat aphid, Rhopalosiphum padi L., are aphid pests of wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), sorghum (Sorghum bicolor L....
Environmental and Host Plant Effects on Insecticide Susceptibility of the Cotton Aphid (Homoptera: Aphididae)
Environmental Host Plant Insecticide Susceptibility Cotton Aphid
2008/12/10
Insecticidal control of the cotton aphid (Aphis gossypii Glover) in California is often erratic. Genetic, selection-induced resistance is certainly a factor in many cases. However, field observations ...
