The pathogenicity of Tetranychus cinnabarinus was studied by using BtR05 strain. Its acaricidal activity was confirmed to prepare BtR05 suspending agent (BtR05 SC). This suspending agent was used to make the indoor toxicity test on the young, nymphae and adult T.

方法］使用BtR05菌株对朱砂叶螨进行致病性研究，确定其杀螨活性后，制备了BtR05悬浮剂，并使用该悬浮剂对朱砂叶螨的幼螨、若螨和成螨进行了室内毒力测定。

The exact of petroleum ether was the acaricidal active site of Eungenia caryophyllata. 3.Isolation, purification and identification of compounds with acaricidal activity in Eugenia Caryphyllata: The exact of petroleum ether was separated into 6 parts by silica gel column chromatography with gradually increasing polarity of petroleum ether: ethyl acetate. The part C was demonstrated to be the most effective part by acaricidal activity test in vitro,and the time for it to kill all experimental mites was about 20 min.

丁香杀螨活性成分的追踪分离、纯化与结构鉴定：采用硅胶柱层析法，以石油醚：乙酸乙酯溶剂系统梯度洗脱，对丁香石油醚提取物进行分离，得到A~F 等6 段混合物，离体杀螨试验发现，C 段混合物具有突出的杀螨活性，50%浓度平均15min可杀死全部供试螨虫。

Methods: The demodex mites were collected by adhesive cellophane tape technique. The killing effects of different volatile oils against Df and Db were observed by microscope. Normal saline and Xinfu Manling Ointment were used as negative and positive controls, respectively.

采用透明胶带粘贴法获取蠕形螨，镜下观察不同中药挥发油对毛囊蠕形螨和皮脂蠕形螨的抑杀作用，并设立新肤螨灵软膏为阳性对照、生理盐水为阴性对照，进行体外抗螨活性筛选。

Cinnabarinus. 500 times dilution of the concentration on the poisoned Tetranychus cinnabarinus better, 96 h in drug corrected mortality of young mite reached 80%, the corrected mortality of the nymphae mite reached above 75%, the corrected mortality of the adult mites reached 60%, which showed that the SC had poisoned the role to all mites.

结果］稀释500倍以下的浓度对朱砂叶螨的毒杀效果较好，在药后96h幼螨的校正死亡率均达到80%以上，若螨的校正死亡率均达到75%以上，成螨的校正死亡率均达到60%以上，表明BtR05悬浮剂对朱砂叶螨的幼螨、若螨和成螨均具有毒杀作用。

BtR05 SC had the toxicity on young, nymphae and adult T. cinnabarinus and its effect endurance of BtR05 SC was higher than control medicament Gold Vinda.

结论］苏云金芽孢杆菌BtR05悬浮剂对朱砂叶螨的幼螨、若螨和成螨均具有毒杀作用，并且其持效性明显高于对照药剂金维达。

The results showed that 3 acaricides, pyridaben, propargite, hexythiazox and 6 insecticides, abamectin, chlorfenapyr, cyhalothrin, emamectin benzoate, oxymatrine prosuler, envidor had good control effects and there was no significant difference among them. It had excellent control effects for 4 low-toxicity insecticides including propargite, hexythiazox, abamectin, and emamectin benzoate.

结果表明，3种专一性杀螨剂哒螨灵、克螨特、噻螨酮及6种广谱性杀虫杀螨剂阿维菌素、虫螨腈、高效氟氯氰菊酯、甲维盐、氧苦内脂和螺螨酯对叶螨均有良好的防治效果，彼此之间差异不显著。

Based on the trials undertaken in the country and elsewhere foliar application of Kasu-B 3% SL is also reported effective for the control of bacterial soft rot on potato, and kiwifruit bacterial canker and Anthracnose on cucurbits, at a dose of 1500 – 2000 ml/ha.

阿维菌素是一种新型无公害生物杀虫杀螨剂，具有强烈胃毒，触杀，内渗作用。主要用于防治各种农作物上的鳞翅目，鞘翅目，同翅目，双翅目害虫及害螨。特别是对抗性小菜蛾，斑潜蝇，螨类有特效。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
