Storability of properly harvested, mature hulless oats (Avena nuda L. ’Terra’) of 9.7–10.5% moisture content was determined from a 24-mo field trial of two 11.5-t lots of oats stored in two wooden farm bins in Manitoba during 1976–78. Oats were stored safely with very low levels of infestation by preharvest fungi, mites and insects and negligible quality loss for up to about 20 mo. Afterwards the grain moisture contents at the bottom layers of both bins rose from about 10 to 13–16%; this led to heavy floor level infestations by the fungi Penicillium and Aspergillus versicolor, and mites Caloglyphus berlesei and Tarsonemus granarius. Fat acidity values rose from the first year levels of about 30 to 50–78 mg KOH/100 g of dry grain. Populations of Cryptolestes ferrugineus and Tribolium castaneum, introduced to one bin, did poorly during the first summer and failed to survive during the second year. A third beetle, Oryzaephilus surinamensis, continued to multiply in small numbers after 22 mo. Low storage temperature levels during most of the years seemed to have affected adversely the multiplication of insects and to a lesser extent mites in farm-stored oats.

New Pest

Infestation potential of 16 cultivars of flax, mustard, rape, sunflower, millet, and clover seeds to five common species of stored-product insects was determined. When multiplication was used as a criterion, whole seeds were resistant to insect attack although minor infestation occurred on certain cultivars. Although some species of insects could complete development on certain cultivars, few could reproduce well on clover and mustard cultivars. Oilseeds were more susceptible to Oryzaephilus mercator than to any other insect species. Cryptolestes ferrugineus, which thrived on the millet cultivars Crown and Siberian, neither reproduced nor completed development on any of the oilseed and forage cultivars. All cultivars of crushed Noralta, Raja, and Redwood flax were susceptible to: O. mercator, O. surinamensis, and Tribolium castaneum; Echo and Target rape only to O. mercator; Armavirec, Krasnodarets, Mennonite, and Peredovic sunflowers to all insects except C. ferrugineus; and Crown and Siberian millet to all insects. Tribolium confusum reproduced only on sunflower and millet cultivars. The potential danger of stored oilseeds in Western Canada from a new pest, O. mercator, was evaluated.
