Online published on 30 November, 2019. Abstract Investigations of affectiveness of grain protectants, containing Eucalyptus citriodora and Rauwolfia serpentina, in protecting wheat grain from insect pests under storage (S. oryzae, R. dominica and T. castaneum) for longer duration showed that the grain protectant (4:1 ratio) @ 1.25% w/w could suppress stored grain insect pests infestation up to 95.0–99.0 and 86.0–98.0 per cent over a period of six and twelve month, respectively, in different storage receptacles. Significance of viability indicated that the treated grain stored in different structure was more viable even after twelve month's storage as compared to untreated grain. The rate of increase in weight loss in treated grains due to insect infestation was also observed very slow i.e. from 0.00 to 0.06 percent in jute bag, 0.07 percent in polythene lined jute bags, 0.19 percent in cotton, 0.08 percent in polythene bags and 0.03 percent in plastic jar after twelve months.
