Complex evolution in Aphis gossypii group (Hemiptera: Aphididae), evidence of primary host shift and hybridization between sympatric species.

open access: yesPLoS ONE, 2021
Aphids provide a good model system to understand the ecological speciation concept, since the majority of the species are host-specific, and they spend their entire lifecycle on certain groups of host plants.

Preference of two populations of Propylea quatuordecimpunctata (Coleoptera: Coccinellidae) for Aphis fabae and Aphis gossypii (Homoptera: Aphididae)

open access: yesEuropean Journal of Entomology, 2015
Prey preference of natural enemies is an important parameter used in studies on their efficiency. Feeding preferences of individuals from two populations of Propylea quatuordecimpunctata (L.) (Coleoptera: Coccinellidae) for the essential prey items ...

Assessing Cotton Genotypes for Resistance to Aphis gossypii (Hemiptera: Aphididae)

open access: yesJournal of Economic Entomology, 2021
Abstract Aphis gossypii Glover (Hemiptera: Aphididae) is a polyphagous species frequently associated with the presence of sooty mold and viruses lethal to plants. The purpose of this work was to characterize possible resistance categories of cotton genotypes against A. gossypii.

New structure in cell puncture activities by aphid stylets: a dual-mode EPG study [PDF]

open access: yes, 2010
Intracellular punctures by aphid stylets appear as potential drop (pd) waveforms in DC electrical penetration graph (EPG) recordings. We used a dual-EPG device that recorded in one channel the ‘full EPG’ with R-plus emf-components (i.e., the usual DC EPG)

Insecticide use and competition shape the genetic diversity of the aphid Aphis gossypii in a cotton-growing landscape [PDF]

open access: yes, 2011
Field populations of the cotton aphid, Aphis gossypii Glover, are structured into geographically widespread host races. In the cotton-producing regions of West and Central Africa (WCA), two genotypes have been repeatedly detected within the cotton host ...

Impact of Temperature on Survival Rate, Fecundity, and Feeding Behavior of Two Aphids, Aphis gossypii and Acyrthosiphon gossypii, When Reared on Cotton

open access: yesInsects, 2021
Aphid performance is sensitive to temperature changes. Previous studies found that Acyrthosiphon gossypii (Mordviiko) was more sensitive to high temperature than Aphis gossypii (Glover).

Baseline susceptibility and cross-resistance in aphis gossypii glover (Aphididae: Hemiptera) to phorate and sulfoxaflor [PDF]

open access: yes, 2013
© 2013 State of New South Wales. Susceptible discriminating doses of phorate (0.2 g/L) and sulfoxaflor (0.01 g/L) against cotton aphid Aphis gossypii Glover were determined by laboratory bioassay where aphids were sprayed with insecticide with the aid of
