Development of the fly ‘crop vessel’ bioassay for fly/microbial studies

July 2017

The dipteran crop has been implicated in many fly/microbe associations. In most cases, reports merely identify that the microbe(s) in question is(are) found inside the crop, but very few studies have focused on their long-term presence within the crop. Possibly, one of the main reasons for this is that flies usually regurgitate their crop contents, which makes it difficult to do long-term studies. Because of this, an in...
