Surveillance of pathogens in selected honeybee populations
This workpackage addresses the population level analyses but will not deal with large scale colony experiments which are neither reliable nor feasible for the thousands of colonies required to address the various drivers of colony death and all their interactions. Instead BEE DOC will use existing data bases and ongoing monitoring activities in the EU, USA and Latin America to extract the potentially important interactions through correlational evidence.
Although these data will be less robust than experimental evidence, we expect to verify our predictions made by the experimental approaches in WP1, 2, and 3 in a real world apicultural setting. In addition, we will screen selected populations which have survived without treatment in spite of Varroa infestations and those which have never been exposed to Varroa infestations.
