The 9 common used insecticides of cypermethrin 4.5%EC, omethoate 40%EC, chlorpyrifos 40%EC, acetamiprid 3%EC, imidacloprid 10%EC provided excellent control for wheat aphids in fields. The control effects were over 90% at 7 days after spraying. The 9 insecticides had bad effects on aphidius and coccinellidae in three days after spraying and the number of two natural enemies decreased rapidly. But on the 7th day, the number of the two natural enemies increased and there were difference between those treated with imidacloprid, acetamiprid and abamectin and CK. BT had no evident difference compared to the control.

为了明确杀蚜药剂对麦蚜的防治效果、适宜的防治时期、对生态环境安全性和粮食作物食品安全性的影响，对4.5%氯氰菊酯、40%氧化乐果、40%毒死蜱、3%啶虫脒、10%吡虫啉等9种防治麦蚜的药剂进行了筛选，发现各药剂对麦蚜的防效较好，喷药后7d防效均在90%以上。9种农药在喷施后的3d内，对麦蚜的主要天敌蚜茧蜂和瓢虫影响较大，两种天敌数量锐减，但到7d时各处理蚜茧蜂数量均有回升，其中不同剂型的吡虫啉、啶虫脒和鲁植顺克处理的蚜茧蜂数量同对照相差不大。

The control effects and application methods of Pleurotus ostreatus on the peanut root knot nematode disease, Meloidogyne arenaria, were systematically studied in the greenhouse.

And Aphelenchoides besseyi with distinct effects; the fermentation liquid of the bacterial strain has higher poisonous activity to second instar larva of Heterodera glycines, and can remarkably restrain cyst hatching; the treatment of fermentation liquid with different diluted concentration is significantly different from the treatment of sterile water; the insecticidal effects of stock fermentation solution can reach above 90%, and the effects of greenhouse experiment are obvious; at the same time, the bacterial strain can remarkably poison the Meloidogyne spp.

该菌株的发酵液对大豆胞囊线虫二龄幼虫具有较高的毒杀活性并显著抑制胞囊孵化，不同稀释浓度发酵液的处理和无菌水处理有显著差异，发酵原液的杀线虫效果可达到90％以上，温室防效试验效果明显。同时该菌株对根结线虫Meloidogyne spp。

A method combining HPLC, a post-column derivation device and a fluorescent detector was used to determine residues of ten carbamate pesticides （aldicarb sulfoxide, aldicarb sulfone, oxamyl, methomyl, 3-hydroxy carbofuran, aldicarb, propaxur, carbofuran, carbaryl and methiocarb） in 68 vegetable and 32 soil samples under four different cultivation systems （traditional kailyard, open field vegetable base, green house and paddy） were collected from a certain city in South Jiangsu.

本研究采用高效液相色谱-柱后衍生-荧光检测法分析了苏南某市4种不同种植方式下（传统菜地、露天蔬菜基地、大棚蔬菜基地和水稻田）68个蔬菜样品和32个土壤样品中10种N-甲基氨基甲酸酯类农药（涕灭威、涕灭威砜、涕灭威亚砜、杀线威、灭多威、残杀威、克百威、3-羟基克百威、甲萘威和灭虫威）的残留量，结果表明在蔬菜中检出的氨基甲酸酯农药残留水平多处于0.2～23μgkg^-1，土壤中为0.1～10μgkg^-1；土壤中3-羟基克百威和灭虫威全部检出，其最高检测浓度分别为10μgkg^-1和1.64μgkg^-1，其他农药仅有少数检出。

Using field plot test, the control effects of three microorganic nematicides: IPC, ZK7 and 412 were tested from tobacco biological character ,infection situation and economic properties.

为了确定3种微生物杀线虫剂IPC、ZK7、412对烟草根结线虫病的防治效果，通过田间小区试验，从烤烟的生物学性状、发病情况、经济学性状等方面进行了全面考察。

The bioassay results showed that parthenolide had nematicidal activity against tested nematode Bursaphelenchus xylophilus and Panagrellus redivivus, and their death rate at 200 μg/ml within 48 h were 70.4% and 100% respectively.
