Geocoris punctipes (Say) was fed artificial diet containing 0, 70, 350 or 700 ppm Rb from 4th-instar nymphal stage to adult stage. Adult weights and duration of nymphal stadia were not affected by Rb treatment. Adult survival was reduced at 350 ppm but was not significantly lower at 700 ppm than at 0 or 70 ppm Rb. Fifth-instar nymphs that were fed 350 ppm and kept under laboratory conditions (i.e., ad libitum food and water, 27°C, 40% RH) retained enough Rb for reliable detection 1 week after return to unlabeled diet.
