Nymphs were reared on maize leafpieces and adults were reared on growing barley seedlings. Mean incubation period of eggs was 16.6 ± 0.1 days at 17–26 °C, and 10.1 ± 0.15 days at 23–33 °C. Nymphal stage was completed in 14.5 days by males and in 15.3 days by females, at 22–32 °C. At this temperature, the five nymphal instars were completed in 3.3, 2.6, 2.3, 3.0 and 4.0 days, respectively. At 23–32 °C, sexual maturity of males and females occurred two and three days, respectively, after adult emergence. At 24–32 °C, mean adult longevity was 19.1 and 44.3 days, for males and females respectively (P < 0.001), and mean pre-oviposition period of females was 5.9 days. Females produced 8–331 eggs/female/life (average = 196.3 eggs); hatchability was 85% in eggs produced by 5–15 day-old females and 65% in eggs produced by 38–49 day-old ones. Moulting and oviposition sites and egg aggregation in host plants are described. Eight generations of C. bipunctella zeae were reared on barley seedlings in the glasshouse, within a period of one year and six days. The shortest generation occurred in June—July (22–35 °C), lasting for 26 days, and the longest occurred in November—February (6–24 °C), lasting for 122 days.Read More
