The-methyl-β-methoxyacrylate compounds containing substituted pyrazole ring I-14、I-16 had good acaricidal activity with 100% control of T.

含吡唑环的甲氧基丙烯酸酯类化合物I-14、I-16在150 mg/L浓度下具有很好的杀螨活性。

Preliminary bioassays indicated that many title compounds exhibited excellent fungicidal, or insecticidal and acaricidal activities. The strobilurin derivatives containing substituted pyrimide ring have lower biological activity than the strobilurin derivatives containing substituted pyrazole ring which exhibited good fungicidal activity against RB (0.92 mg/L), TLB (0.3 mg/L), CDM (12.5 mg/L) and WPM (1.56 mg/L).

初步生物活性测定结果表明，新型Strobilurin类化合物中多个化合物具有较好的杀菌或杀虫杀螨活性，其中吡唑类化合物要明显优于嘧啶类化合物，吡唑类化合物在低浓度下对水稻稻瘟病菌(0.92 mg/L)、番茄晚疫病菌(0.3 mg/L)、黄瓜霜霉病(12.5 mg/L)和小麦白粉病(1.56 mg/L)仍具有很好的杀菌活性。

初步生物活性测定结果表明，新型Strobilurin类化合物中多个化合物具有较好的杀菌或杀虫杀加热管螨活性，其中吡唑类化合物要明显优于嘧啶类化合物，吡唑类化合物在低浓加热管度下对水稻稻瘟病菌(0.92 mg/L)、番茄晚疫病菌(0.3 mg/L)、黄瓜霜霉病(12.5 mg/L)和小加热管麦白粉病(1.56 mg/L)仍具有很好的杀菌活性。

Objective: To investigate the relationship between breeding density of acaroid mites in the storages of house and potential allergic asthma risks in Huainan area for preventing the disease on population basis.

目的：了解淮南地区房舍储藏物粉螨孳生密度与过敏性哮喘发病之间的关系，为人群过敏性哮喘的防治提供依据。

Of them Dorylaimida, Acaraina, and Araneae fell into the category of dominant orders; while 11 orders such as Collembola, Hymenopteraetc, Mononchida, Rhabditida pertained to the common ones, which constituted the major groups of soil animals; and the rest of them the rare ones.

其中矛线目、蜱螨目、蜘蛛目属于优势类群，弹尾目、膜翅目、单齿目、小杆目等11个目属于常见类群，构成了常宁市土壤动物的主体，余下的18个目为稀有种类。

This shows that only from Rm perspective, Tetranychus urticae Koch in the four host plants and foods diet for the adaptation to the best in the kidney beans, the second is in peach leaf,the third is in apple leaf,the last on is in balsamine leaf.

这表明只从r_m角度来考虑，二斑叶螨在这4种寄主植物上的适应度和嗜食性以在菜豆上最好，在桃叶上较好，在苹果上次之，在凤仙花上最差。净增长率R0表示每雌经历一个世代可生产的雌性后代数。

The dominant groups of soil fauna were highly correlated with soil organic matter content, and Coleoptera, Diplura and Chilopoda might be adapted to reside in relatively high pH value soils.

土壤有机质和全氮对土壤动物特别是弹尾目和蜱螨目有显著的正效应，土壤速效磷含量也与优势类群表现为正相关；鞘翅目、双尾目和唇足纲表现了能适应相对较高pH值的土壤环境。

The results showed that: Collembola ticks and mites heads the dominant group, the total catch of 80.42 percent, is the main area of soil animals.

结果表明：弹尾目和蜱螨目为优势类群，占全捕量的80.42%，是该区土壤动物的主体。

The results showed that there existed a close relationship between the concentration of Pb and the community structure of soil animal. Among the 1289 individuals collected in the experiment, the dominant genera are Collembola, Prostigmata and Oribatida, which amounted to 78.2% of the total.

在获得的1289个土壤动物中，优势类群为弹尾目、前气门亚目和甲螨亚目，3个优势类群占土壤动物全捕量的78.2%，对动物群落结构起决定作用。

Objective To develop a direct and effective method to screen drug that can kill human Demodex in vitro.

目的 寻找一种简便易行和定量的体外抗人体蠕形螨药物筛选的实验方法。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
