dc.descriptionThe survival and molting incidence of fifth-instar nymphs of Panstrongylus megistus (Burmeister, 1835), a vector of Chagas' disease, were investigated following sequential heat shocks in which a mild shock (35 or 40 degrees C, 1 h) preceded a more drastic one (40 degrees C, 12 h). The shocks were separated by 8-, 18-, 24-, or 72-h periods at 28 degrees C. The heat-shock tolerance response was more effective when the first shock was given at 40 degrees C. When the period between shocks was 18 h, the tolerance to sequential shocks (in terms of specimen survival) weakened, which suggested a transient control of the process that enables the organism to circumvent the unfavorable effects of severe shock. In terms of molting incidence, the heat-shock tolerance was only demonstrated when the period between the first shock at 40 degrees C for 1 h and the second shock at 40 degrees C for 12 h was > or = 24 h. These results are the first to demonstrate the induction of heat-shock tolerance in a blood-sucking hemipteran.
