Introduction Hemp, or industrial hemp, is a high value alternative crop that has seen major increases in acreage in Canada since commercial production was legalized in 1998. The term industrial hemp applies to non-psychoactive varieties of Cannabis sativa L. There have been reports of insect infestations on stored hemp seed in Manitoba. The moths Plodia interpunctella (Hübner) Indianmeal moth, and Ephestia küehniella (Zeller) Mediterranean flour moth feed on hemp seed (Hagstrum and Subramanyam, 2009). Our objectives were to determine which stored-product beetles can reproduce on hemp and the effect of dockage and seed moisture content. 2. Materials and Methods Twenty adult insects were placed on 15 g of hemp seed at two different moisture contents (~8% or ~15%) and two different dockage levels (~0% or~15%) and held at 30 O C and 60-70% relative humidity. The number of live and dead insects were counted at 3, 5, 7 and 9 weeks. Only live adults were returned to vials. 3. Results and Discussion These insect populations increased over the 9 weeks; red flour beetle [ Tribolium castaneum (Herbst)], drugstore beetle [ Lasioderma serricorne (F.) ] saw-toothed grain beetle [ Oryzaephilus surinamensis (L.) ] , warehouse beetle ( Trogoderma variabile Ballion). These insect populations did not increase: rusty grain beetle [ Cryptolestes ferrugineus (Stephens) ] , lesser grain borer [ Rhyzopertha dominica (F.) ] , rice weevil [ Sitophilus oryzae (L.) ] , flour mill beetle ( Cryptolestes turcicus (Grouvelle), confused flour beetle ( Tribolium confusum Jacquelin du Val), cigarette beetle [ Stegobium paniceum (L.) ] . In general, higher dockage led to higher populations. The effect of moisture content was variable.
