By Lukasz Stelinski Ants can be involved in mutualistic relationships with honeydew-producing hemipterans. Ants provide protection against their natural enemies, and in return, hemipterans reward ants with honeydew. Such mutualism may affect population regulation of hemipterans by third trophic level predators. However, current knowledge regarding the effects of this food-for-protection mutualism of ants with Asian citrus psyllid (ACP, Diaphorina citri) …
