Effects of Transgenic Bt Rice on the Population Development of Nephotettix cincticeps;
轉(zhuǎn)Bt基因水稻克螟稻對黑尾葉蟬種群增長的影響
t The impacts of two Bt transgenic rice lines TT9-3 and TT9-4 both of them contain a heterozygous gene of crylAb + crylAc from Bacillus thuringiensis, on the field population dynamics of Sogatella furcifera and Nephotettix cincticeps, as well as dominant spider species were evaluated.
結(jié)果表明,Bt稻與親本對照(IR72)田間白背飛虱和黑尾葉蟬成蟲的蟲口密度在整個(gè)水稻生育期間無顯著差異,而若蟲密度有一定的不同。
The virus is transmitted by Nephotettix cincticeps in a circulative, persistent manner.
該病毒可由黑尾葉蟬(Nephotettix cincticeps)作為昆蟲介體,它是一種經(jīng)卵以持久方式傳播的病毒。
