Research objectives and content
Leafcutter ants are major agricultural pests in (sub)tropical America. During millions of years of evolution these ants have become dependent on the cultivation of a clonally propagated fungus, which they farm in underground nest-chambers. Several natural adaptations may explain the evolutionary success of leafcutter ants, i.e. the way in which their colonies and crops are able to resist pathogens and other stress factors: 1. Production of antibiotic glandular secretions in variable qualities and quantities. 2. Active manipulation of genetic diversity of workers and fungus gardens within nests by multiple mating and/or joint nest-founding of queens. 3. Local co-adaptation between lineages of ants and symbiotic fungus, ensuring maximal productivity and resistance to parasites.
An explicit study of these factors and their interactions is the objective of this proposal.
