| Abstract: | Several physiological indices of Sogatella furcifera(Horváth),namely,the oviposition rhythm,fecundity,sex ratio,body weight,and daily honeydew excretion of adult,and duration and survival of nymph,etc., were tested on four hybrid rice combinations with different resistances to this insect.The results showed that besides the moderately resistant Xieyou 46,the Shanyou 6,Shanyou 63,and Shanyou 85 were all susceptible,in which Shanyou 85 was moderately susceptible.As compared with the susceptible common rice variety TN1,all the indices of these susceptible hybrid rice combinations mentioned above were higher.It was suggested that the populization of susceptible hybrid rice combinations such as Shanyou 6 and Shanyou 63 in recent years is favorable to the rampancy of WBPH. |
