Decision making by generalist and specialist aphids with the same genotype.

Journal of insect physiology - 1 Jul 2003

Tosh Colin R, Powell Glen, Hardie Jim

Abstract excerpt

One idea to explain the high incidence of specialisation in phytophagous insects is that their nervous systems are simple and unable to efficiently recognise multiple host plants. Here this 'neural limitations' hypothesis is tested using a generalist (the summer winged virginopara) and specialist (the autumn gynopara) morph of a single clone of the black bean aphid, Aphis fabae, that are almost identical...
