Preventing Transmission of Lethal Disease: Removal Behaviour of Lasius fuliginosus (Hymenoptera: Formicidae) Towards Fungus Contaminated Aphids

open access: yesInsects, 2021
The ability of ants to detect and remove conidia-contaminated aphids, aimed at limiting contacts with potentially dangerous entities, is an effective antifungal mechanism to prevent the spread of infection among both their nestmates and aphids, their ...

The semiochemistry of aphids

open access: yesNatural Product Reports, 2013
Chemical signalling between aphids (small insects that suck plant sap) formating and avoidance of antagonistic organisms, and between aphids and plants for location of hosts or avoidance of unsuitable plants, employs minute levels of small lipophilic molecules (SLMs), termed "semiochemicals". These semiochemicals, which include sex and alarm pheromones,
