The possibility of varietal resistance of rice to the rice water weevil, Lissorhoptrus oryzophilus Kuschel, has been considered by previous researchers. Isely and Schwardt (1934) noted that some varieties had larger numbers of larvae than others. I failed to find statistically significant differences in larval populations among 8 varieties, but I did find a difference in varietal yield response to controlling rice water weevil (Bowling 1963). Rolston and Rouse (1964) found 2 modern and 2 obsolete varieties similar in susceptibility to rice water weevil larval infestations.
