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。

Its insecticidal active ingredients are sesquiterpenoid polyol esters with a dihydroagarofuran structure. These compounds are stable to light, heat, and pH, and exert a narcotic and toxic poisoning action. Celastrus angulatus contains a plant-origin insecticide with a unique mechanism of action. Celangulins, a 0.2% emulsifiable concentrate has already been developed for insect control.
是我国广泛分布的一种杀虫植物,其杀虫有效成分基本上均是以二氢沉香呋喃为骨架的多元酯类化合物,对光、热和pH值均稳定,对害虫主要表现为麻醉和毒杀作用,苦皮藤是一类作用机理独特的植物源杀虫剂,在其实际杀虫的应用上,已经开发出了0.2%苦皮藤素乳油。

ELISA method was used for comparison. Results The positive rate of DIGFA in testing the serum from 50 infected rats was 96.0%(48/50). The negative rate of DIGFA in healthy rats was 100%(50/50). Cross reaction with Enteroclysis (13 samples) and Tapeworm (11 sqamples) was not observed. The cross reaction rate in 18 Strongyloidiasis rats was 5.6%. The sensitivity and specificity of DIGFA is comparable with ELISA (96.7%).
结果 用DIGFA检测广州管圆线虫实验感染鼠血清50份,其阳性检出率为96.0%,50份正常鼠血清的阴性符合率达100%,DIGFA分别检测蛲虫阳性鼠血清13份,绦虫阳性鼠血清11份和粪类圆线虫阳性鼠血清18份,前二者均为阴性,后者交叉反应率为5.6%;DIGFA与ELISA平行检测30份广州管圆线虫阳性鼠血清,两法符合率达96.7%。

Results We discovered and confirmed that there were 17 different species of 1st intermediate host of in Paragonimus Jiangxi, covering 2 families and 3 genera, and 23 different species of 2nd intermediate host, covering 1 order, 1 family and 3 genera, 15 of which were reported to be new species by the authors. Furthermore, a new genus of Jiangxi Huananpotamon was built up, based on the assumption that Wuyi mountain range is the developing centre of Huananpotamon , and tend to spread out towards Jiulian mountain of Nanling mountain range adjacent to Guangdong Province and Luoxiao mountain range next to Hunan Province. In addition, Jiangxi Province freshwater crab order was created at the end of research, as well as a complete classification and retrieval table of its order and genus. The authors also proved that the advantageous stocks of freshwater crabs carrying encysted metacercaria of Jiangxi Paragonimus westermani were Sinopotamon fukiense and S.wanzaiense .
结果 江西卫氏并殖吸虫第一中间宿主淡水螺种或媒介共计17种,隶属2科3属;第二中间宿主淡水溪蟹种或媒介为23种,隶属1总科1科3属,其中15种为作者等研究发现报告的新种;建立了江西并殖吸虫媒介新属——华南溪蟹属,认为武夷山脉是华南溪蟹属类群的分化中心,并有向与广东毗邻的南岭山脉的九连山和与湖南接壤的罗霄山脉扩展的趋势;建立了江西省淡水蟹类总科及科与属的分类检索表;证实携带江西卫氏并殖吸虫囊蚴的淡水溪蟹优势种群为福建华溪蟹、万载华溪蟹
