The black earwig Euborellia annulata Lucas lays eggs underground on Coroyra cephalonica, Plutella xylostella (Lepidoptera) or mashed catfood showed that the hatching rate was 86.96 to 100 percent (average 96.14 percent) with temperature 25°C and humidity 85 percent
57.40 to 95.20 percent (average 84.26 percent) with temperature 30°C and humidity 75.5 percent. The nymphal period. of Euborellia annulata at 25°C was longer than at 30°C (average 58.2 days and 47.74 days). The life cycle of this species at 25°C was with 72.23 +/- 4.25 days longer than with 59.73 +/- 4.95 at 30°C. However, the life expectancy of Euborellia annulata females is longer than of male in both conditions in laboratory. At 25°C and humidity of 85 percent adults of black earwigs can eat 76.13 aphids, 16.80 diamondback moths or 13.66 cutworms per day at the first - second larval instars. Black earwigs have an enhanced ability to inhibit cutworms on cabbage by releasing 2 earwigs per square meter.
