Six varieties of wheat were selected from Hebei, Henan and Shandong provinces, which were LiangXing 66, Fanmai 8, Xinong 979, Zhengmai 7698, Jimai 22 and Aikang 58, respectively. The moisture content of grain was adjusted to 12.5% after sampling from field. Each test sample in weight of 16 grams was infested by six parent weevils which ratio of female to male was four to two. The emergence time and progeny number of adults, weight changes of test sample were checked. And the sensitive coefficient was calculated according to the checked data. The results showed that in Jimai22 the mean development duration of the insect was shortest, for 40.8 days, and the number of progeny was biggest, 46 adults. The sensitive coefficient of Jimai22 to the weevil was 9.40. In Xinong979 the mean development duration of the insect was 42. 6 days. The number of progeny was 8 adults. And the sensitive coefficient of Xinong979 was 4.98. The beginning time, peak number time and ending time of adult eclosion for the insect was gotten short for Jimai22 that the resistance to insects was on the lowest level. For Xinong979 that the resistance to insects was on top level, the beginning time and ending time of adult eclosion were bigger than others, but not the biggest number. For Liangxing66 that the resistance to insects was less than that of Xinong979, the ending time was longer than that of others. There was a little of change on weight of samples in the days from the insect egg infesting to beginning time of adult eclosion. The results showed that there were obvious differences in resistance to insects between wheat varieties. The smaller sensitive coefficient was，the more the progeny number was. The eclosion duration was not entirely consistent with trends of sensitive coefficient; and there was no obvious correlation between the sensitive coefficient and the weight change of wheat infested by the insect.
