Morphometric relationship, phylogenetic correlation, and character evolution in the species-rich genus Aphis (Hemiptera: Aphididae). [PDF]
The species-rich genus Aphis consists of more than 500 species, many of them host-specific on a wide range of plants, yet very similar in general appearance due to convergence toward particular morphological types.

Cotton varieties resistant to Thrips tabaci exhibit lower soluble sugar and free amino acid levels, with smaller post‐infestation increases in these nutrients, resulting in reduced feeding rates and lighter damage. Key resistance evaluation indices include: damage severity, soluble sugars, free amino acids, soluble proteins, superoxide dismutase ...

Quantifying Imidacloprid Susceptibility in Populations of Aphis gossypii
Aphis gossypii Glover is a highly polyphagous pest that causes economic losses to many crops worldwide. Evolution of resistance to insecticides is a major concern when managing populations of A. gossypii, and resistance has been reported in numerous studies.

The Spatial Pattern of Aphis gossypii οn Cotton
The spatial distribution of Aphis gossypii (Glover) on cotton was studied by using Taylor’s power law, the negative binomial parameter k and the iδ-index of aggregation. Both k and iδ were related to density with curvilinear relationships and indicated that aggregation decreases as density increases up to densities of, approximately, two individuals ...
