Identification of Aphids Living onCitrus

Species identification of aphids (Insecta: Hemiptera: Aphididae) through DNA barcodes.

A 658-bp fragment of mitochondrial DNA from the 5' region of the mitochondrial cytochrome c oxidase 1 (COI) gene has been adopted as the standard DNA barcode region for animal life. In this study, we test its effectiveness in the discrimination of over 300 species of aphids from more than 130 genera. Most (96%) species were well differentiated, and sequence variation within species was low, ave...

Aphids

Historically the diverse areas of communication research have rarely met, and this factor probably prompted my feeling that the order of chapter delivery in this book was counter-intuitive. Naturally our investigation of any communication system has always been heavily influenced by our own language, and the historical progress of research has broadly progressed 'down' from humans to other mamm...

Identification of the Living Familiar face recognition

The task of the police officer investigating a crime, or of the forensic anthropologist working with human remains, is to establish an identity of a criminal or of a victim. This often involves working with images of faces – building a composite image from the memory of a witness to the crime, seeking CCTV images of the person or persons who might have committed the crime, or building a model o...

Salivary proteins of aphids, a pilot study on identification, separation and immunolocalisation.

Salivary proteins (SPs) of Schizaphis graminum, Acyrthosiphon pisum and Myzus persicae were studied after probing and feeding on different artificial diets. Salivary sheaths as well as apical lumps of saliva were found, presumably representing subsequently excreted saliva of different types. Phenoloxidase, pectinase and peroxidase activities were detected by staining the enzyme-converted produc...
