What are the characteristics of house fly eggs as described in the provided text?
- They are large, dark, and laid singly
- They are white, banana-shaped, and laid in clusters
- They are pale, legless, and move toward food
- They are hard-shelled and found in cracks in buildings
Show answer
Eggs are white, banana-shaped, about 1.2 mm, and laid in clusters.🔗 Source
In terms of seasonality and survival, how do house flies behave during cooler conditions?
- They die off immediately when temperatures drop below summer levels
- They enter a state of pupation that lasts until spring
- They can survive for about three months and may overwinter in sheltered spots or building cracks
- They become more active and produce more generations in the winter
Show answer
...but cooler conditions can stretch survival to about three months, and some overwinter outdoors in sheltered spots or in cracks inside buildings.🔗 Source
When distinguishing the house fly from the stable fly, what is the most significant difference in their feeding habits?
- The house fly bites skin while the stable fly sponges liquid
- The house fly has a piercing mouthpart while the stable fly has a sponging mouthpart
- The house fly cannot bite, while the stable fly has a stiff, bayonet-like mouthpart for piercing skin
- The house fly feeds on blood while the stable fly feeds on decaying matter
Show answer
It doesn't bite... the stable fly... carries a stiff, bayonet-like mouthpart for piercing skin and feeding on blood, so a biting 'house fly' is almost always a stable fly.🔗 Source
According to the life cycle of the house fly, what is the correct order of metamorphosis stages?
- Egg, pupa, larva, adult
- Larva, egg, pupa, adult
- Egg, larva, pupa, adult
- Egg, larva, adult, pupa
Show answer
House flies develop through complete metamorphosis: egg, larva (maggot), pupa, and adult.🔗 Source
A technician observing a significant house fly population in a livestock facility should prioritize which management action to effectively reduce the population?
- Apply insecticide directly to the adult flies resting on walls
- Remove or manage the manure and organic waste breeding sources
- Install 14- to 16-mesh screens on all barn openings
- Deploy sticky flypaper throughout the feedlot
Show answer
Treating adults while a manure or garbage source keeps producing new ones just wastes product; the source has to go first.🔗 Source
Which of these is considered a diagnostic sign of an active house fly breeding source?
- Presence of large red eyes on surfaces
- Finding pale maggots in nearby garbage or manure
- Presence of four dark stripes on the walls
- A sudden increase in the number of adult flies in summer
Show answer
A more diagnostic clue is the dark 'fly specks' scattered on surfaces... Pale maggots in nearby garbage, manure, or rotting matter point to an active breeding source.🔗 Source
Which physical characteristic serves as a primary field mark for identifying an adult house fly (Musca domestica)?
- A single pair of dark lengthwise stripes on the thorax
- Four dark lengthwise stripes on the thorax
- A stiff, bayonet-like mouthpart
- A single pair of wings that are dark in color
Show answer
The best field mark sits on the thorax, the middle body segment, which carries four dark lengthwise stripes.🔗 Source
Which of the following best describes how house flies facilitate the transmission of pathogens like Salmonella or Campylobacter?
- Through direct bites to humans and animals
- By laying eggs directly into human food and beverages
- By carrying germs on their body and in their saliva and droppings
- Through the release of airborne pathogens from their wings
Show answer
...contaminates food and surfaces by carrying germs on its body and in its saliva and droppings.🔗 Source
