Calcium Action Potentials in the Developing Oocytes of an Insect, Rhodnius Prolixus

1. Action potentials (APs) have been recorded for the first time from the oocytes of an arthropod, the haematophagous insect Rhodnius prolixus. In saline containing Zmmoll" calcium, APs could be evoked by depolarizing the oocyte membrane from its resting potential of — 50 mV to a threshold between —35 and — 40 mV. The mean duration and overshoot of the APs were 2-6 s and +16mV, respectively. 2....

Changes associated with laboratory rearing in antennal sensilla patterns of Triatoma infestans, Rhodnius prolixus, and Rhodnius pallescens (Hemiptera, Reduviidae, Triatominae).

We examined changes in the array of antennal sensilla of three species of Triatominae (Triatoma infestans, Rhodnius prolixus, and R. pallescens) following their establishment for different periods in laboratory culture. In each case, the laboratory colonies were compared with conspecific samples taken directly from the field, by quantitative analysis of the sensilla arrays on the three distal s...
