We used a model plant-aphid system to investigate whether the aphid-specific entomopathogenic fungus Pandora neoaphidis responds to aphid-induced defence by the broad-bean plant, Vicia faba. Laboratory experiments indicated that neither in vivo sporulation, conidia size nor the in vitro growth of P. neoaphidis was affected by Acyrthosiphon pisum-induced V. faba volatiles. The proportion of conidia germinating on A. pisum feeding on previously damaged plants was significantly greater than on aphids feeding on undamaged plants, suggesting a direct functional effect of the plant volatiles on the fungus. However, there were no significant differences in the infectivity of P. neoaphidis towards A. pisum feeding on either undamaged V. faba plants or plants previously infested with A. pisum. Therefore, these results provide no evidence to suggest that P. neoaphidis contributes to plant indirect defence strategies.

D006790	Host-Parasite Interactions	The relationship between an invertebrate and another organism (the host), one of which lives at the expense of the other. Traditionally excluded from definition of parasites are pathogenic BACTERIA; FUNGI; VIRUSES; and PLANTS; though they may live parasitically.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001042	Aphids	A family (Aphididae) of small insects, in the suborder Sternorrhyncha, that suck the juices of plants. Important genera include Schizaphis and Myzus. The latter is known to carry more than 100 virus diseases between plants.
