Many species of flies of the two-winged type, Order Diptera, such as mosquitoes, horse-flies, blow-flies and warble-flies, cause direct parasitic disease to domestic animals, and transmit organisms that cause diseases. These infestations and infections cause distress to companion animals, and in livestock industry the financial costs of these ...
Typically the mandibles are the largest and most robust mouthparts of a chewing insect, and it uses them to masticate (cut, tear, crush, chew) food items. Two sets of muscles move the mandibles in the coronal plane of the mouth: abductor muscles move insects' mandibles apart ( laterally ); adductor muscles bring them together ( medially ).
Unlike houseflies, adult black soldier flies have greatly reduced sponging mouthparts, meaning they can only consume liquids such as flower nectar, although they typically do not eat at all. Unlike houseflies, which regurgitate food along with digestive enzymes, adult black soldier flies therefore do not spread pathogens or diseases.
The flies are pool feeders. Their saliva, which contains anticoagulants, a number of enzymes and histamine , is mixed with the blood, preventing clotting until it is ingested by the fly. These bites cause localized tissue damage, and if the number of feeding flies is sufficient, their feeding may produce a blood-loss anaemia .
The mouthparts of orthopteran insects are often used as a basic example of mandibulate (chewing) mouthparts, and the mandibles themselves are likewise generalized in structure. They are large and hardened, shaped like pinchers, with cutting surfaces on the distal portion and chewing or grinding surfaces basally .
All meals must be a fluid in order for the flies to access the meal because Megaselia scalaris has sponging mouthparts. [11] This is a characteristic common to the family Phoridae. The sharp teeth possessed by adults are not used in retrieval of a food source, like a piercing mouthpart, but are instead used to aid digestion and breakdown of ...
The discovery of nearly 30 invasive fruit flies has prompted a produce quarantine affecting over 79 square miles (204.6 square kilometers) of Los Angeles County as state and local officials try to ...
Adult horse-flies feed on nectar and plant exudates; males have weak mouthparts, but females have mouthparts strong enough to bite large animals. This is for the purpose of obtaining enough protein from blood to produce eggs. The mouthparts of females are formed into a stout stabbing organ with two pairs of sharp cutting blades, and a ...
