草地螟

In this paper,techniques of reverse transcription polymerase chain reaction and rapid amplification of cDNA ends have been used to clone a gene,which encodes a general odorant binding protein,from the antennae of Loxostege sticticalis.

利用RT-PCR结合RACE技术克隆了编码草地螟触角中一种普通气味结合蛋白的基因。

According to present results and the forecast of the sunspot activity cycle, the authors predict that the fourth outbreak period of meadow moth will be coming during 2017-2020 and reach the peak during 2024-2025 in China.

根据这些结果，并结合太阳黑子活动周期的预测，草地螟在我国的第4个大发生周期很有可能开始于2017~2020年之间，并在2024~2025年间达到高峰。

The development of adult ovary and dissected supervision of it's matting status are one of evi dence as forcasting occurrence amount and time for young beet webworm.

成虫卵巢发育及交配状态的解剖监测是预测草地螟幼虫发生数量和时间的依据之一。

Meadow webworm had come into it's third outbreak cycle since 1996,the larvae population density of first generation was more than 10 000/m~2,and the cumulative areas of damaged grassland reached 1 300 million hm~2 which was increased about 800 million hm~2 than that of the second outbreak cycle.

此周期内该省草地螟累计发生面积近1 333万hm2次，比上个周期增加了近800万hm2，草地螟1代幼虫密度最高达每m210 000头以上，尤其2004年在该省大范围内达到特大发生，有13个县田间百步惊蛾达到万头以上，个别高达50 000头以上。

To put forward long term forecasting, investigation on emergence amount and total distribution area of over winter larva of meadow moth is necessary.

据此提出今后要搞好草地螟长期预报，必须跟踪观察各代幼虫越冬的比率和面积大小。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
