There are five forms exhibited by ant-Homoptera ‘mutualism’ and 
these have been exhaustively discussed in a review by Way (1963). 
‘Mutualism’ is defined as “an association between ants and other in- 
sects which is mutually beneficial without necessarily implying obli- 
gate dependence or interdependence” (Way, 1963). These forms 
include: (i) adaptation of the Homoptera related to the association 
with ants; (ii) benefits derived by the Homoptera; (iii) benefits 
derived by the ants in form of contribution of the Homoptera to the 
food of the ants; (iv) specificity in the ant-Homoptera association; 
(v) ant-Homoptera association in relation to their natural control.
