Tetramorium manobo (Calilung, 2000) |
This ant is associated with the aphid, Toxoptera odinae (van der Goot). It was found alone underneath leaves of Arundo donax Linn. (Poaceae). It solicits honeydew from the aphid by brushing with its antennae the posterior end of the aphid's abdomen. When the aphid raises its abdomen, honeydew is excreted. (Calilung 2000)
