Aphid probing behaviour in evolutionary context Aphids (Hemiptera: Aphidoidea) comprise families Aphididae, Adelgidae, and Phylloxeridae. Adelgidae and Phylloxeridae separated from Aphididae early in the evolution of the group in the Jurassic and retained several ancient morphological and bionomical characters. The Read more…

Behavioural responses of aphids to allelochemicals in plant tissues The relationship between aphids and plants is in some ways unique among insects. The process of host-plant selection in aphids is composed of several stages that include random and directed flight, Read more…

Modification of aphid probing behaviour with natural and structurally modified terpenoids Aphids transmit nearly 30% of all known plant virus species and 50% of insect-borne viruses. Plant diseases caused by these viruses may reduce yields by up to 80%. The Read more…

Application of Electrical Penetration Graph (EPG) technique in studies on plant responses to aphid probing Aphids feed on the phloem sap using their specialised sucking-piercing mouthparts, which penetrate plant tissues intercellularly until they reach vascular tissue. During penetration, aphid stylets Read more…
