About Drosophilids

The secretophagous non-biting flies of relevance for the transmission of two Thelazia species in dogs belong to the genus Phortica. These drosophilids, commonly known as ‘fruit flies’, display a slightly ‘unusual’ behaviour as they feed on lachrymal secretions of humans and carnivores. They are furthermore used by pathogens to invade vertebrate hosts.
