The scientific activity of D.A. Grasso concerns mainly Behavioural Ecology and Sociobiology. In particular, the main topics of his research regard several aspects of ant biology (Hymenoptera, Formicidae) studied with a multidisciplinary approach. Behavioural, morpho-functional, chemical and bioacoustical investigations were conducted and were mainly focused on the reproductive behaviour, foraging, raiding activity, alarm and defence, territorial marking, orientation, reproductive behaviour and colony founding in both social parasites (such as slave-making ants) and free-living species. Other topics concern ecological aspects, such as intra- and inter-specific competition in different ant species (mainly Messor harvester ants), as well as the sociogenetics of incipient colonies. Recently started investigations are addressed to the study of the ant fauna as possible bioindicator for measuring environmental quality, especially in areas with a strong impact of human activities, such as the agro-ecosystems. Finally, further recent researches are devoted to investigate social structure and organization of harvester ants of the genus Messor. Moreover, investigation are also focused on the symbiotic relationships involving ants and other organisms such as phytophagous insects (e.g. aphids and mealybugs) and on how ants may affect the action of their natural enemies (such as coccinellid beetles) both in natural conditions and during biological control. Symbiotic relatioships with bacteria and plants are also investigated.
