Prior to the experiments, wasps experienced only the host plant and the mummy from which they emerged. The body length of adult Aphis gossypii apterae ranges from 0.9-1.8 mm. Nutrition and secondary metabolites in plants affect herbivore preference and performance, but it is still not clear which factors determine the host range and host preference of polyphagous herbivores. high powered lens and they certainly agree with the general colour and Values are the average of … Although Aphis gossypii is well-known to show phenotypic plasticity in colour and size to an Its head and thorax are black, the abdomen yellowish-green with black lateral spots and the antennae are longer than those of the apterous female. Parthenogenesis on these hosts allows large populations of aphids to build up quickly. 37 Full PDFs related to this paper. Which reminds me, I ought have said why our initial identification was Aphis gossypii is known to transmit at least 50 plant viruses. host plants may be an effective measure to suppress A. gossypii outbreaks, because cotton and cucumber are often grown together in fields and greenhouses. Micrographs of whole mounts in alcohol are shown below. Whilst we make every effort to ensure that identifications are correct, we cannot absolutely warranty their accuracy. nearby colony are on a plant of Hypericum androsaemum. Hill (1987) points out that many ecological studies have failed because of the inability of the observer/recorder to recognise a mixed species population. If you have time I should be interested in your views on the Aphis chloris In this experiment, the host-selection behavior, as well as the physiological mechanism based on the analysis of growth, development and energy substances, and the expression of the olfactory-related genes of the cotton aphid, Aphis gossypii, were studied under ambient (407.0 ± 4.3 μl/L) and elevated (810.5 ± 7.2 μl/L) CO 2.
