A laboratory experiment was carried out to test the larval development of lesser grain borer. Rhyzopertha dominica Fabrecios on different varieties of wheat Triticum aestvum Linn was evaluated at Department of Zoology, D.B.S. College, Kanpur, India during 2004 to 2005 in protected and unprotected condition. The data revealed significant differences among six wheat varieties namely TL 174, K 65, HI 774, UPT 72294, Kalyan Sona and HD 1982 for larval development of R. dominica. The data revealed significant differences among various wheat varieties for larval development of R. dominica. The lowest larval period 27.50 days was found in HI 7747 followed by HD 1982 and Kalyan Sona having the larval period 27.76 and 29.20 days respectively. These do not differ significantly to each other. In HI 7747 one larva could not complete its development even up to 48 days and it was dead before population. The highest larval period (33.44 days) was observed in UPT-72294 followed by K 65 and TL 174 having the larval period 32.42 and 31.54 days respectively. These three varieties do not differ significantly each other but differ significantly from the others.
