ABSTRACT

This work was carried out to evaluate the effect of different temperatures on different Chrysoperla raimundoi Freitas & Penny development stages in the laboratory. Eggs around 24h were individualized in glass tubes and kept at 19, 22, 25, 28 and 31º C; 60 ± 10 RH and 12h of light. The larvae were fed with Sitotroga cerealella (Oliver) eggs. Evaluations were made of the viability and the developmental time of the egg, of each instar, the larval stage, the pre-pupae and pupae and biological cycle; moreover, the base temperature (Tb) and the thermal constants (K) of these stages was determined. It was observed that the developmental time of C. raimundoi in different development stages decreased as the temperature increased. Generally, it did not have any effect on the viability of the different stages. The base temperature varied from 8.9 to 17.1º C and the thermal constants from 18.25 to 335.34 GD, in function of the duration of each phase of development of the insect.
