摘要:

应用实验种群生命表数据分析毛竹林本土优势种竹盲走螨和引进种胡瓜钝绥螨对毛竹4种害螨南京裂爪螨、竹裂爪螨、竹缺爪螨、竹刺瘿螨的控制能力。结果表明①胡瓜钝绥螨取食上述4种害螨的世代存活率分别为90.4 %、77.55%、87.93%、81.63% ,每雌总产卵量分别为38.12粒、45.77粒、35.59粒、30.26粒,而乡土优势种竹盲走螨取食上述4种害螨的世代存活率分别为95.23%、100%、87.7%、80.48% ,每雌总产卵量分别为44.5、46.8、41.15、20.1粒;②竹盲走螨以南京裂爪螨为猎物时其内禀增长率(0.155)与引进种胡瓜钝绥螨(0.154 )相近,均明显高于南京裂爪螨(0.1089) ;③竹盲走螨以竹裂爪螨为猎物其内禀增长率(0.152)与胡瓜钝绥螨(0.152)相同但明显低于竹裂爪螨(0.192) ;④竹盲走螨以竹缺爪螨为猎物时其内禀增长率为(0.148)明显低于引进种胡瓜钝绥螨(0.175)和其猎物(0.185) ;⑤竹盲走螨取食竹刺瘿螨易大量逃跑,雌螨产卵量低,引进种胡瓜钝绥螨取食竹刺瘿螨能正常生长发育,但是其内禀增长率(0.144 )明显低于其取食上述其余3种害螨的内禀增长率,产卵量高于当地种竹盲走螨,并描述1998年以来每年5—6月助迁人工繁殖的胡瓜钝绥螨控制毛竹害螨蔓延的效果。

Abstract:

In this paper, the parameters of experiment population life table of the nature enemy mite Typhlodromus bambusae and introduced enemy Amblyseius cucumeris were studied in the laboratory to evaluate their potentials as a biocontrol agent against the 4 species in Moso Bamboo forests. The result showed that :(1)The generation survival rate of A. cucumeris were 90.40%, 77.55%, 87.93%, 81.63% and average fecundity of per female of A. cucumeris were 38.12, 45.77, 35.59, 30.26 when if feeding on S. nanjingensis, S. bambusae, A. corpuzae, A. bambusae. The generations survival rate of T. bambusae<.i> were 95.23%, 100%, 87.1%, 80.48% and average fecundity of per female of T. bambusae were 44.5, 46.8, 41.15, 20.1 when if feeding on S. nanjingensis, S. bambusae, A. corpuzae, A. bambusae; (2)The intrinsic rate of natural which has been known as the most important parameter of population increase of T. bambusae (0.155) was very similar to the A. cucumeris(0.154) and higher than their prey, S. nanjingensis(0.089);(3)The intrinsic rate of natural increase of T. bambusae (0.152) was very similar to the A. cucumeris(0.152) and both lower than their prey S. bambusae; (4) The intrinsic rate of natural increase of T. bambusae (0.148) is lower than of A. cucumeris (0.175) when they were feeding on A.corpuzae(0.185);(5) The intrinsic rate of natural increase of A. cucumeris(0.144) is lowed when if feeding on A. bambusae than 3 spider mites of Moso Bamboo. T. bambusae showed a lower fecundity when feeding on A. bambusae than those of A. cucumeris and most females tested escaped from experimental areas since 1998 A. cucumersis was released to control pests mites into Moso Bamboo forests during May-July. It has been showed that A. cucumeris may be a better biological control agent of pest of Moso Bamboo.
