RESUMO
The effects of constant temperatures (18, 20, 25, 30 and 32ºC) on the rate of development of Doru luteipes Scudder and Doru lineare Eschs (Dermaptera: Forficulidae), predators of the maize pest Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) were evaluated. From D. lineare, the maternal care, the influence of two diets on this predator and the growth model of the forceps in male were investigated. The development of D. luteipes were completed at 18, 20 and 25ºC, and ranged from 38.4 days (25ºC) to 80.0 days (18ºC). D. lineare completed its development at 18, 20, 25 and 30ºC, ranged from 25 (30ºC) to 75 days (18ºC). The number of eggs in the patch was 29,7 ± 8,43 (means ± SD), the incubation period of eggs ranged between 7 and 10 days, the females proceeded agressively, when their nest were menaced, to make evidence of the eggs and young nymphs protection for the females. Intraspecific recognition of the eggs did not happen. Behaviors, such as eggs and nest cleaning and the lower viability of eggs in the absence of mother, were verifyed. The number of eggs, the pre-reproductive period, the time of egg-adult development, as well as, the viabilities of eggs and nymphs were similar for the two diets (larvae of Drosophila melanogaster Meigen (Diptera: Drosophilidae) associated to the commercial pollen of Apis mellifera L. (Hymenoptera: Apidae), and pupae meal of Bombyx mori L. (Lepidoptera: Bombycidae) associated to the commercial pollen of A. mellifera). Was verified that larvae of D. melanogaster can be used for the establishment of colonies of this predator in laboratory. It was verified that the growth model of the male forceps, in relation to the body size, is isometric for all the measures in the forceps, except for the distance between the internal spine and the terminal spine, that was alometric for both forceps. Comparing the left and the rigth forceps, biometric variation is not observed, presenting bilateral simmetry in both forceps.
