Abstract
|
Rice water weevil (Lissorhoptrus oryzophilus Kuschel) is a major international phytosanitary object , Xiangtan City, the first time in 2005 found that the rice water weevil . This paper studies the morphological characteristics of the rice water weevil instars understand the law in order to find the optimum control period, control the occurrence of hazards and diffusion of the rice water weevil . The rice water weevil adults peak occurs four times in the morning and evening rice fields : immigration period , from mid-April to early May for the overwintering generation moving into the peak of the end of April ; June for the first generation of the rice water weevil emergence period ; July move into the late early to early August for the rice water weevil adult Honda the immigration period ; mid-August to early September for the second generation of the rice water weevil emergence . Pharmaceutical experimental screening to triazophos, poisoned barnyard , avermectin control rice water weevil adults , first proposed the rice water weevil larvae to imidacloprid . Specific analysis of the effectiveness of the prevention and control of rice water weevil pointed out the significance of effective prevention and control of rice water weevil .
