- We performed laboratory experiments to study maternal care in Doru lineare Eschs. (Dermaptera: Forficulidae), a predator of the maize pest Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae). Females laid 29.7 [plus or minus] 8.43 (SD) eggs which took 7-10 days to hatch. Mothers searched for an appropriate nest, where they cleaned and defended eggs and nymphs. Females did not recognize eggs from other females as foreign and adopted them. Other evidence of maternal behavior was also observed, such as egg-cleaning, nest-cleaning, and a lower viability of eggs not cared for by females.
