Many animals and plants possess symbiotic microorganisms inside their body, wherein
intimate interactions occur between the partners. The Insecta, often rated as the most …

Host plant resistance is an efficient and environmentally friendly means of controlling
insects, including aphids, but resistant-breaking biotypes have occurred in several plant …

Polyphenism is the phenomenon where two or more distinct phenotypes are produced by
the same genotype. Examples of polyphenism provide some of the most compelling systems …

Background Recent genomic analyses of arthropod defense mechanisms suggest
conservation of key elements underlying responses to pathogens, parasites and stresses. At …

Injection of siRNA (small interfering RNA) into parthenogenetic adult pea aphids
(Acyrthosiphon pisum) is shown here to lead to depletion of a target salivary gland transcript …

Nine proteins secreted in the saliva of the pea aphid Acyrthosiphon pisum were identified by
a proteomics approach using GE‐LC‐MS/MS and LC‐MS/MS, with reference to EST and …

The role of insect saliva in the first contact between an insect and a plant is crucial during
feeding. Some elicitors, particularly in insect regurgitants, have been identified as inducing …

The osmotic pressure of plant phloem sap is generally higher than that of insect body fluids.
Water cycling from the distal to proximal regions of the gut is believed to contribute to the …

Gaining insight into the mechanisms of chemoreception in aphids is of primary importance
for both integrative studies on the evolution of host plant specialization and applied research …

Background RNA interference (RNAi) is a powerful method to inhibit gene expression in a
sequence specific manner. Results Here, we described the development of RNAi by micro …
