Rangeland Pest Control Practice Test

How many generations per year does the Black Grassbug have?

Two generations per year One generation per year Three generations per year Continuous generations

Correct Answer:

One generation per year

Explanation:

The concept being tested is how many generations a pest completes in a year (voltinism). The Black Grassbug is univoltine, meaning it goes through one full life cycle in a year. In typical rangeland conditions, the season provides just enough time for one egg-to-adult generation to develop and reproduce before conditions become unfavorable again. There isn’t time for a second complete generation, so only one generation occurs annually. Two or more generations or continuous generations would require a longer or warmer season and overlapping life stages, which doesn’t fit this species in the usual study context.
