(R,S)‐(2,3‐dihydroxypropyl)adenine, 9‐(2‐phosphonylmethoxyethyl)adenine and D‐eritadenine injected at 0.001–1% concentrations into female flight muscles of Rhodnius prolixus significantly affected their reproduction. Both germarium and vitellarium showed pycnotic cells and degenerative changes of trophic syncytium. Some follicles were vacuolated or invaginated with at least partially resorbed oocytes. Eggs were laid irregularly, the average number of eggs per female per day was 0.83–3.30 (4.45 in controls) and their weight was 10–30% lower. Hatchability of treated females reached 42–67% compared to 84.6% in controls. Changes in Rhodnius prolixus reproduction were dose‐dependent with all compounds studied. D‐eritadenine was an order of magnitude more effective than remaining compounds studied. Fecundity recovered within 3–4 weeks following treatment.
