基金Particularly the FAO/IAEA Coordinated Research Project"Colony management of insects for sterile insect technique application"allowed to exchange valuable information related to the study of key symbiont species associated to massproduced insectsFunding was provided by FAO/IAEA contract 22662funded through the ERASMUS+International mobility program KA107.
