米易县传布水稻黄矮病病毒的介体昆虫是二条黑尾叶蝉[Nephotettix apicalis(Motschulsky)]。当地每年发生五代,无明显越冬现象。本文报道了该虫在自然变温条件下各代、各虫态的历期、予测式、发育起点温度和有效积温。以日均温度C°为变量(x)的各代历期(y)予测式是:y=186.6951-5.0239×±5.9215;r=-0.9849。直线相关达到极显著水平。防治二条黑尾叶蝉的最适时机是一月上旬和中旬。
The mediator insect that propagated the rice yellow dwarf virus in Miyi was Nephotettix apicalis (Motschulsky). Occurred five times a year in the local area, no significant winter phenomenon. In this paper, we report the duration, predictor, developmental onset temperature and effective accumulated temperature of each insect and insect state under natural temperature conditions. The historical periods (y) of each generation with the daily average temperature C ° as a variable (x) are: y = 186.6951-5.0239 × ± 5.9215; r = -0.9849. Linear correlation reached a significant level. The best time to control two black-tailed leafhoppers is early January and mid-January.
