Influência da temperatura e umidade na biologia de Rhodnius neglectus Lent, 1954 em laboratório (Hemiptera, Reduviidae,Triatominae)

the objective of the present paper was to study the development of r. neglectus in the laboratory under different conditions of temperature and humidity. three groups were prepared: 33/40 (33+/- 1oc and 40% +/-5% ur), 33/70 (33+/- 1oc and 70% +/-5% ur), and 28/70 (28+/- 1oc and 70% +/-5% ur). all these groups were observed daily to evaluate the eggs' incubation period, the development period of each instar nymph, the mortality rate of each stage, the frequency of feeding and the hatching - adult ecdysis period. the embryonic development showed significant differences between the treatment given, the group 33/40 presented the lowest incubation period. the lowest bloodmeals number was observed in the group 33/40 except for the first instar (group 28/70). the period of nymphal development was significantly reduced in the group 33/40, however, the mortality was high and the specimens did not reach the adult phase.
