Abstract The effect of nitrogen fertilization on Aphis gossypii Glover color and size, fertility, and intrinsic rate of increase (rm) was studied on cotton plants. [...] Key Method Nitrogen fertilization treatments consisted of 0, 50, 100, and 150% of the agronomic recommended level. Adult and nymph densities, as well as rm, were positively correlated with nitrogen fertilization. Aphid body length, head width, and darkness of color were recorded in populations on cotton plants fertilized with 100% nitrogen or…Expand
Influence of Nitrogen Fertilization on Biology of Aphis Gossypii (Hemiptera: Aphididae) Reared on Chrysanthemum Iindicum (Asteraceae)
TLDR
The present data suggest that plant nitrogen content is an important factor contributing to the increase severity of the cotton aphid as a pest of chrysanthemum. Expand
Effect of nitrogen fertilisation on biology, life table parameters and population abundance of greenbug; Schizaphis graminum (Rondani) (Hemiptera: Aphididae)
TLDR
Number of wingless aphids on treated wheat plants significantly increased with increase in fertilisation level while the number of winged aphids produced decreased, and statistical analysis demonstrated aphid’s feeding on plants treated with higher fertilisation significantly had higher R0, DT, T, and r m. Expand
Performance and population growth rate of the cotton aphid, and associated yield losses in cucumber, under different nitrogen fertilization regimes
Performance and population growth rate of the cotton aphid Aphis gossypii Glover, and the yield losses inflicted by that pest, were studied in relation to varying nitrogen fertilization levels (90,Expand
Effect of Nitrogen Fertilizer on the Intrinsic Rate of Increase of Hysteroneura setariae (Thomas) (Homoptera: Aphididae) on Rice (Oryza sativa L.)
TLDR
Second-generation aphids produced on 150% N plants had significantly higher survivorship, fecundity, and rm regardless of the N treatment of plants that parents fed on, indicating that the effect of a high N diet was expressed in a second generation of aphids. Expand
Effect of nitrogen fertilization on life table parameters and population growth of Brevicoryne brassicae.
TLDR
The greenhouse study on aphid population growth on various treatments indicated that 21 day after infestation, highest number of aphid and lowest number of winged were found on treated cabbage with 150% of recommended nitrogen fertilization, which means that higher nitrogen fertilizer improves the suitability of oilseed rape for cabbage aphid whose performances are then increased.

Influences of fertilization on Aphis gossypii and insecticide usage
TLDR
Reduction in time to harvest could result in significant reduction of insecticide usage by reducing the time for aphid population growth and high fertilization together with minimal runoff may be a useful tactic to an integrated pest management programme for managing A. gossypii on potted chrysanthemums. Expand
Influences of fertilization on Aphis gossypii and insecticide usage
Abstract:  Fertilization levels for ornamental crops may influence pest population dynamics, crop quality, and pest management strategy. We examined the effect of fertilization on population growthExpand
Demographic parameters of Lipaphis erysimi on canola cultivars under different nitrogen fertilization regimes.
TLDR
Management of nitrogen fertilization and cultivation of resistant cultivar could be suitable eco-friendly strategies to manage mustard aphid population. Expand
Reproductive performance of striped mealybug Ferrisia virgata Cockerell (Hemiptera: Pseudococcidae) on water-stressed cotton plants subjected to nitrogen fertilization
TLDR
Proper fertilization and irrigation management relieving plant from stress can be helpful in avoiding generalized infestations of striped mealybug on cotton. Expand
The effect of nitrogen fertilizer on the cotton aphid (Aphis gosypii) when grown in the cucumber (Cucumis sativus)
TLDR
Overall, it was found that nitrogen affected the progeny number, population, and life span of A. gossypii. Expand

Phenotypic Plasticity in Australian Cotton Aphid (Homoptera: Aphididae): Host Plant Effects on Morphological Variation
TLDR
The inescapable conclusion from this study is that A. gossypii in Australia is phenotypically plastic and its morphology is affected by the host plant far more strongly than by genetic differences (if any) among means of local populations. Expand
Dwarf Phenotype of the Cotton Aphid, Aphis gossypii Glover (Hemiptera: Aphididae)
TLDR
An orthogonal experiment demonstrated that production of yellow dwarfs can be induced by presumed less-suitable host-plant species at temperatures of 15 ° and 25 °, but not 20 °C, and possible advantages of the yellow dwarf developmental pathway are discussed. Expand
The nutritional quality of phloem sap utilized by natural aphid populations
TLDR
It is suggested that EDTA‐exudation may be a useful technique to study nutritional correlates of aphid life cycles, e.g. the time of migration between primary and secondary plant hosts. Expand
Herbivory in relation to plant nitrogen content
TLDR
The evidence that N is scarce and perhaps a limiting nutrient for many herbivores, and that in response to this selection pressure, many Herbivores have evolved specific behavioral, morphological, physiological, and other adaptations to cope with and uti­ lize the ambient N levels of their normal haunts is examined.

Randomization tests : Example using morphological differences in Aphis gossypii (Homoptera: Aphididae)
TLDR
A new methodology is introduced for using randomization tests to determine if the average of several observations is different from a constant, and an extension of the method is used when the null hypothesis states that there are differences. Expand
