title: [Changes in the level of ecdysones in the last 2 instars of Panstrongylus megistus (Heteroptera: Reduviidae)].
abstract: The ecdysone titre in the hemolymph during the two last instars of P. megistus was studied by radio-immunology technique. Changes observed are very similar in both instars. Two peaks of inequal amplitude are present. The first, always lower than the second, occurs at 1/3 of the intermoult whereas the second, distinctly higher, is observed at 2/3 period of the intermoult.
