根据各位版友的建议，修改了一下

Rice planthopper，an important insect of rice crops in China, is often controlled by application of high-toxic pesticides such as methamidophos in agricultural production. Since Jan. 1st 2007, agricultural application of five high-toxicity pesticides, including methamidophos, has been forbidden. Therefore nationwide tests on substitute species for methamidophos have been conducted to evaluate the effects of control for rice planthopper, and to study relevant techniques, then to provide scientific basis on demonstration and extensive application in a large area.

好难啊，有专业词汇呢

我觉得第一句用important 不合适
用one of the main harmful insect 比较合适。

翻译的很棒啦

Agree with happyjyl (1/F), 试验 => experiments  (better than tests; 试验基地 : experimental site)
Agree with sharkwein (5/F), 害虫 => pest  (better than insect)
Agree with ruojun (9/F), 效果 => efficacies  (better than effect)
Agree with redanqi (11/F), 经常 => generally  (the original 有”通常”的意思; as I mentioned in 10/F, I consider that the original Chinese version has room for improvement)

Suggestion:
科学依据 : scientific evidence
水稻稻飞虱是我国水稻重要害虫之一 : In China, rice planthopper is one of the major pests hosted in the rice (the words “major”, “pests” and “hosted” are referred to http://quarantine.entomol.nchu.edu.tw/Quarantine/quarantine_pests-Taiwan.htm)

I suggest that the finalized version should be based on the one at 9/F.
