Myiasis And House/Stable Flies.

Sarcophaga is a type of fly that is commonly known as the flesh fly. One distinguishing characteristic of the Sarcophaga fly is that it has a chess board appearance on its abdomen. This means that the abdomen of the fly has a pattern that resembles the squares on a chess board. This pattern is unique to Sarcophaga flies and helps to identify them. Therefore, the statement that Sarcophaga has a chess board appearance on its abdomen is true.

Musca domestica is characterized by wing vein 4 bending up sharply to wing vein 3. This means that in the fly's wing structure, the fourth wing vein bends sharply upwards towards the third wing vein. This characteristic is unique to Musca domestica and helps in identifying and distinguishing it from other species. The presence of this specific wing vein arrangement is a defining feature of Musca domestica.

Flies of the fannia genus have wing veins 4 and 3 that are almost parallel. This statement is true because the fannia genus of flies does indeed have wing veins 4 and 3 that are almost parallel. This characteristic is a distinguishing feature of flies in this genus.

Including shigella, E.coli, Salmonella and Cholera.
Viruses include polio
They may transmit helminth eggs.

Fannia scalaris is indeed known as the latrine fly. This species of fly is commonly found in and around human habitats, particularly in areas with poor sanitation. They are attracted to and breed in decaying organic matter, including feces, which is why they are often found near latrines and sewage systems. Therefore, the statement that Fannia scalaris is known as the latrine fly is true.

Ironing clothes is a method of control.

The correct answer is "Vomiting up food from its crop to digest solid material." Musca domestica, also known as the housefly, feeds by regurgitating food from its crop, which is a specialized organ in its digestive system. This allows the fly to break down solid food into a liquid form that it can then ingest. This process is necessary because the housefly's mouthparts, known as the proboscis, are adapted for sucking up liquid food rather than chewing solid material. Feeding on plant sugars is not the primary method of nutrition for houseflies.

It is caused by Chlamydia trachomata and is common in refugee camps.

Invasion is by the larvae of dipterous insects.

Musca domestica, commonly known as the housefly, has three larval instars. During its life cycle, the housefly undergoes complete metamorphosis, which includes four stages: egg, larva, pupa, and adult. The larval stage is divided into three instars, during which the larvae molt and grow in size. After the third instar, the larvae enter the pupal stage and eventually emerge as adult houseflies. Therefore, the correct answer is 3.

It is 'tumbu or mango' fly. Bot fly is dermatobia hominis.

This occurs in Musca domestica. In fannia they are almost parallel.

Calliphoridae is the family of flies that includes the genera Calliphora and Lucilia. These flies have prominent bristles on their dorsal thorax, giving them a metallic appearance. Additionally, their larvae do not have spines. Therefore, the correct answer is Calliphoridae - Calliphora and Lucilia.

Both males and females blood feed.

Dermatobia hominis is the correct answer because it is commonly known as the human botfly, which lays its eggs on the skin of animals or humans. The larvae then burrow into the host's skin and live there for a period of 10+ weeks, causing painful skin lesions. The other options, Tumbu, Calliphora, and Muscina stabulans, do not have a similar life cycle where their larvae live in the host for such a long duration.

Cochliomya hominivorax, also known as the primary screwworm fly, is a metallic fly that is obligate and has 3 stripes on its thorax. This fly is known for its parasitic behavior, as it infests the open wounds of warm-blooded animals, including humans, and feeds on their tissue. The metallic coloration and distinct thorax stripes are characteristic features of this species.

No, they are the flys of screw worms. Flesh flies are Wohlfahrtia and Sarcophaga.

Musca sorbens is a vector of disease in Africa, Asia, and the Pacific. This means that this particular species of fly is responsible for transmitting diseases in these regions. It is important to be aware of this vector in order to prevent and control the spread of diseases in these areas.

Musca domestica, commonly known as the housefly, is known to defecate approximately every 5 minutes. This frequent defecation is due to their rapid digestion process. Houseflies feed on a variety of organic matter, including feces, and their digestive system is designed to quickly process this food source. As a result, they produce waste frequently, making them potential carriers of diseases and contaminants. This behavior highlights the importance of proper hygiene and sanitation measures to prevent the spread of pathogens associated with houseflies.

Stomoxys has a proboscis. A proboscis is a long, tubular mouthpart that is used for feeding. It is commonly found in insects such as flies and mosquitoes. Stomoxys, also known as the stable fly, is a blood-sucking fly that feeds on the blood of mammals, including humans. Its proboscis allows it to pierce the skin and suck blood.

Whilst it can transmit trypanosomiasis, it is unimportant in its transmission and it doesn't spread other bacteria or viruses as it doesn't go to faeces or festering wounds.

Packing tips tight to kill larvae is a method that can be used to control houseflies because it helps prevent the larvae from hatching and developing into adult flies. Bacillus thuringiensis is a biological insecticide that specifically targets and kills houseflies. Insecticide is a general term that includes various chemical substances used to kill or repel houseflies. Bed nets, on the other hand, are typically used to prevent mosquito bites and are not effective in controlling houseflies.

The question asks for the flies that cause obligatory myiasis. Obligatory myiasis refers to a condition where the larvae of certain fly species must parasitize living tissue in order to complete their life cycle. Among the given options, Dermatobia hominis, Cordylobia anthropophaga, Chrysomya bezziana, and Cochliomya homonivorax are known to cause obligatory myiasis. These flies lay their eggs on or near living tissue, and the hatched larvae feed on the host's flesh. Therefore, selecting these flies would cause obligatory myiasis.
