The survival of nymphs and adults of the black field earwig, Nala lividipes , was best when they were reared on germinating seeds of wheat, sorghum, maize and sunflower. Survival was very low for earwigs reared on soybean, and no nymphs survived to adulthood in the absence of seeds or when reared on chickpea or cotton. Life‐table data indicated that population increases were possible only when the earwigs were reared on sorghum, maize, and wheat in ascending order. Numbers remained constant when fed on sunflower and declined if soybeans were the only food available. Rearing was at a constant temperature of 28°C (± 0.5°C) with a black cracking clay at 40% moisture.
