The susceptibility to Sitotroga cereallela (Olivier) infestation in some paddy varieties was carried out in the Food Storage Technology Laboratory, Department of Biology, Federal University of Technology, Akure (FUTA) at ambient temperature and relative humidity. Twenty varieties of paddy Orzya sativa obtained from National Institute of Cereal Research, Badeggi, Niger State were screened for their susceptibility. The results were based on means of moth emergence, percent weight loss and developmental period after the completion of first generation under controlled laboratory conditions. It was found that none of the varieties was completely immuned to insect infestation. The result showed that Cisdane, FARO 36, FAROX-228-4-1-1, and BG 90/2 varieties were least susceptible while NERICA 1, WITA 4, FARO 12, IRAT 133 and ITA 230 were most susceptible to infestation by S. cerealella. NERICA 1 was the most susceptible variety of all the paddy rice varieties screened. With advances in biotechnology and plant breeding, it is possible to transfer desirable characters from resistant varieties in other to improve their resistance to post-harvest infestation by Sitotroga cerealella. Key words: Oryza sativa, Susceptibility, Sitotroga cerealella, Developmental period
