The thrips life cycle vary in length from seven to 14 days at fluctuating temperatures between 68-98 degrees F that are common in most greenhouses.

Then the prepupal and pupal stages take an additional 4 days and generally occur in the soil. Five days apart until thrips are under control. Newly emerged females begin to lay eggs within 1 to 4 days in summer and within 10 to 35 days in winter reproduction being much faster in warmer weather.
