Bayesian inference for generalized stochastic popula- tion growth models with application to aphids
"... Summary. In this paper we analyse the effects of various treatments on cotton aphids (Aphis gossypii). The standard analysis of count data on cotton aphids determines parameter val-ues by assuming a deterministic growth model and combines these with the corresponding stochastic model to make predict ..."

MOLECULAR BIOLOGY AND PHYSIOLOGY Foliar Antioxidant Enzyme Responses in Cotton after Aphid Herbivory
"... Cotton aphid (Aphis gossypii G.) populations in the field have fluctuated over the past years, yet it is unknown whether infestation by these insects alters cotton (Gossypium hirsutum L.) physiology. Although it is important to determine if aphids con-tribute to plant stress, there is only limited i ..."

"... Abstract A new strategy, which is based on immunoassay, has been developed to screen locally isolated Bacillus thuringiensis (Bt). Delta endotoxins of three Bt strains (INS 2.13, HFZ 24.3 and GU 9.1) were prepared, electrophoresed on native PAGE and electroeluted the purified delta endotoxins from ..."

gels. Determined the toxicity of purified delta endotoxins against cotton aphids (Aphis gossypii) and whiteflies (B. tabaci). N-terminal sequences of the purified proteins (δ-endotoxins) of these three entomocidal Bt isolates showed no significant homology to protein sequences in the Gen bank (NCBI
RESEARCH ARTICLE Salt Stress Effects on Secondary Metabolites of Cotton in Relation to Gene Expression Responsible for Aphid Development
"... Many secondary metabolites have insecticidal efficacy against pests and may be affected by abiotic stress. However, little is known of how plants may respond to such stress as per-tains the growth and development of pests. The objective of this study was to determine if and how salt stress on cotton ..."

on cotton plants affects the population dynamics of aphids. The NaCl treatment (50mM, 100mM, 150mM and 200mM) increased contents of gossypol in cotton by 26.8–51.4%, flavonoids by 22.5–37.6 % and tannic by 15.1–24.3 % at 7–28 d after salt stress. Compared with non-stressed plants, the population of aphids
Indian Bt Cotton Varieties Do Not Affect the Performance of Cotton Aphids
, 2008
"... Cotton varieties expressing Cry proteins derived from the soil bacterium Bacillus thuringiensis (Bt) are grown worldwide for the management of pest Lepidoptera. To prevent non-target pest outbreaks and to retain the biological control function provided by predators and parasitoids, the potential ris ..."

. To explore possible indirect effects of Bt crops we here examined the impact of Bt cotton on aphids and their honeydew. In climate chambers we assessed the performance of cotton aphids, Aphis gossypii Glover (Hemiptera: Aphididae) when grown on three Indian Bt (Cry1Ac) cotton varieties (MECH 12, MECH 162

Aphid Honeydew Quality as a Food Source for Parasitoids Is Maintained in Bt Cotton
, 2014
"... Bt-transgenic cotton has proven to be highly efficient in controlling key lepidopteran pests. One concern with the deployment of Bt cotton varieties is the potential proliferation of non-target pests. We previously showed that Bt cotton contained lower concentrations of insecticidal terpenoids as a ..."

result of reduced caterpillar damage, which benefited the aphid Aphis gossypii. It is thus important that non-target herbivores are under biological control in Bt cotton fields. The induction or lack of induction of terpenoids could also influence the quality of aphid honeydew, an important food source
