  • The occurrence and development of rice water weevil(Lissorhoptrus oryzophilus Kuschel) were studied in Fujian.The results indicated that the rice water weevils annually developed by one generation.Thus far,significant damages caused by the rice water weevils were only found in two counties,i.e.,Fuding and Xiapu.There were 1597.6 hectares of rice field in total that were infested by the pest.The infested areas were distributed in 21 towns in the two counties by the end of 2004.The occurrence and degree of damage by the rice water weevil were more obviously affected by the rice varieties and the ecotopic environment of paddy fields.The study revealed that the degree of damage by the pests of L.oryzophilus was more serious on glutinous rice than hybrid rice.The density and the damage rate of L.oryzophilus on the seedlings were higher than those on the transplanted plants in the rice field.
