Sample questions
Regarding the sex differences in Oriental cockroaches, which of the following is true?
- Males are wingless while females have short wings
- Both sexes are able to fly to find mates
- Males have short wings that fall short of the abdomen tip, while females are essentially wingless
- Both sexes can scale smooth vertical surfaces
Show answer
Males have short wings that fall well short of the abdomen tip; females are essentially wingless, resembling overgrown nymphs. Neither sex flies or scales smooth vertical surfaces.🔗 Source
Which of the following is a recognized health risk associated with Oriental cockroach infestations?
- The transmission of airborne pathogens through skin contact
- Bites that cause localized skin irritation
- Allergen exposure via shed exoskeleton fragments and feces
- Direct venomous stings to humans
Show answer
Both the Illinois Department of Public Health and UC IPM tie cockroaches to allergic and asthmatic reactions; Illinois explains that shed exoskeleton fragments and feces act as airborne antigens.🔗 Source
What is the typical lifespan of an adult Oriental cockroach?
- About two months
- Exactly one year
- From about a month to six months
- Between 18 to 24 months
Show answer
Adults live from about a month to six months.🔗 Source
Which inspection method is recommended for detecting Oriental cockroach populations?
- Placing sticky traps along walls and near drains, plumbing, and moisture sources
- Using light traps near bright food preparation surfaces
- Searching exclusively in dry, high-traffic areas of the home
- Checking only the exterior mulch for activity
Show answer
Sticky traps and glue boards best detect populations and pinpoint harborage; place them along walls and near drains, plumbing, and heat or moisture sources.🔗 Source
When differentiating the Oriental cockroach from the American cockroach, which characteristic is a defining feature of the Oriental cockroach?
- It is larger, measuring around 1½ inches
- It is reddish-brown in color
- It is darker, smaller, and has short- or no-wings
- It is full-winged and can fly
Show answer
The American cockroach is larger (around 1ý inches), reddish-brown rather than near-black, and full-winged; the Oriental is darker, smaller, and short- or no-winged.🔗 Source
How does the development time of the Oriental cockroach compare to that of the German cockroach?
- It is much faster, taking only two months
- It is slower, taking roughly a year to 18 months from egg to adult
- It takes exactly six months to reach adulthood
- It is roughly the same, taking approximately two months
Show answer
It is a slow grower: UF/IFAS reports about a year from egg to adult and the Illinois Department of Public Health an average near 18 months — far slower than the German cockroach's two months.🔗 Source
The Oriental cockroach's egg capsule (ootheca) typically contains approximately how many eggs?
- 16 eggs in two rows
- 7 eggs in a single row
- 30 eggs in a cluster
- 100 eggs in multiple rows
Show answer
Eggs ride in a capsule (ootheca) holding about 16 eggs in two rows, taking roughly 42 to 81 days to hatch.🔗 Source
When managing an Oriental cockroach problem, what is recommended alongside chemical control?
- Increasing indoor humidity to attract them to traps
- Eliminating all light sources in the basement
- Conducive-condition correction, such as repairing leaks and drying harborage
- Only focusing on outdoor mulch removal
Show answer
Fold conducive-condition correction into the job — repair leaks, dry harborage, block drains — alongside chemical control.🔗 Source
