Aphids (Hemiptera: Sternorrhyncha: Aphididae) are one of the most economically important groups of insects as agricultural pests and vectors of plant diseases. This website provides an account of 67 species of common aphids of the southern Indian state of Karnataka. This site has been developed as an identification aid to common aphids of Karnataka, many of which also occur in other parts of India and the world. Brief diagnostic accounts, based mainly on external characters to aid in field identification and also supported by other taxonomic characters and photographs, have been given for the species included.

For viewing some sections of this site properly, you need to have the Java Virtual Machine version 1.4.2 or greater (also called Java runtime environment) installed in your computer.

Java Virtual Machine appropriate for your computer / browser can be freely downloaded and installed from www.java.com. 

We hope the site will be informative and useful to economic entomologists, plant protection workers and students of entomology.
