  ABSTRACT: The influence of gamma radiation on the mating behaviour of the red date palm weevil (RDPW), Rhynchophorus ferrugineus (Olivier), and the efficacy of sterile insect technique (SIT) under different levels of relative humidity (RH) were studied. No adverse effects of gamma radiation were observed on the mating behaviour parameters of the RDPW, such as mate recognition time, mating duration, mating frequency within a 30-min period and duration between consecutive matings. However, the weevils were sexually stimulated during aggregation. RH significantly affected egg laying as well as egg hatching. Significantly lower egg laying and hatching were recorded at 25% RH than at higher humidity levels, suggesting that low humidity conditions are better for successful SIT manipulations in the field. Lifespan of irradiated RDPW males was significantly shorter than that of un-irradiated controls, irrespective of RH level.
