Abstract
In laboratory tests in Kansas, grain from 6 cultivars of wheat, all originating from the hard winter wheat area of the state, was stored for 3 years at 26.5 deg C and 60% R.H. and then exposed to adults of Sitophilus oryzae (L.) from strains that had been reared on wheat, maize or sorghum for several years. The ratings for the susceptibility to oviposition (judged by progeny production) of samples of all the cultivars to insects from the 3 different sources were very similar. In addition, the susceptibility ratings were similar to those for grain that had not been stored. In general, the progeny production of adults from strains reared on maize or sorghum was less than that of adults from the strain reared on wheat.ADDITIONAL ABSTRACT:Grains of six cultivars were aged for three years at 60% relative humidity and 26.5 deg C and then exposed to Sitophilus oryzae. Significantly fewer insects developed on Chanute and Parker than on the other varieties
