Effect of cotton cultivar on development and reproduction of Aphis gossypii (Homoptera: Aphididae) and its predator Propylaea japonica (Coleoptera: Coccinellidae).
The results indicate that high gossypol in host cotton had an antibiotic effect on A.gossypii and showed a positive effect on growth and development of P. japonica at the third trophic level, which suggests compatibility between one form of host plant resistance and biological control by predators.
Effects of elevated CO2 and transgenic Bt cotton on plant chemistry, performance, and feeding of an insect herbivore, the cotton bollworm
The damage inflicted by cotton bollworm on cotton, regardless of the presence or absence of insecticidal genes, is predicted to be more serious under elevated CO2 conditions because of individual compensatory feeding on host plants caused by nitrogen deficiency.
Evaluation of the Functional Response of Selected Arthropod Predators on Bollworm Eggs in the Laboratory and Effect of Temperature on Their Predation Efficiency
All predators consumed the highest number of bollworm eggs at 35°C and the lowest numbers at 15°C; predation rate at 35 °C was four times higher than that at 15 °C; the effect of temperature on their predation behavior are discussed.
Impact of Elevated CO2 on Tri-Trophic Interaction of Gossypium hirsutum, Aphis gossypii, and Leis axyridis
This study provides the first empirical evidence that changes in prey reared on host plants grown at different levels of CO2 can alter the feeding preference of their natural enemies.
Impact of elevated CO2 on the third trophic level: A predator Harmonia axyridis and a parasitoid Aphidius picipes
It is indicated that elevated CO2 markedly changes the predation/parasitization preference by the predator/Parasitoid for wheat aphids and the biocontrol efficiency of A. picipes-parasitized S. avenae can be enhanced in Elevated CO2; simultaneously, elevatedCO2 has adverse effects on the growth and development of H. axyridis and A.picipes.
Site-Specific Irrigation and Nitrogen Management for Cotton Production in the Southern High Plains
Upland cotton (Gossypium hirsutum L.) production in the Southern High Plains is usually limited by water and N. The most prevalent means of irrigation in this region is center-pivot, and injection
A mechanistic model based analysis of cotton aphid population dynamics data
1 A 2‐year field study was conducted to generate data on seasonal abundance patterns of cotton aphids Aphis gossypii Glover and to develop a mechanistic model based on cumulative population size. The

Abstract Laboratory clip-cage studies were conducted to quantify the temperature-dependent development, survivorship, and reproduction and to generate life history characteristics and population
Interactive Effects of Elevated CO2 and Cotton Cultivar on Tri-Trophic Interaction of Gossypium hirsutum, Aphis gossyppii, and Propylaea japonica
It is speculated that A. gossypii may become a more serious pest under an environment with elevated CO2 concentrations because of increased survivorship of aphid and longer development time of lady beetle.
