利用上、下解技巧研究了具离散时滞的扩散Musca domestica苍蝇模型的波前解,给出了波前解存在的条件。
Background: The residual effect of triflumuron and pyriproxyfen on Musca domestica L larval stages was studied in the laboratory.Methods: Both IGRs at varying concentrations ranging between 0.5 to 2.5...
The toxicity of chlorfenapyr was evaluated against susceptible and pyrethroid resistant strains (laboratory and field collected) of house fly (Musca domestica L.). In one laboratory strain no cross-...
舍蝇(Musca domestica vicina)凝集素的分离、纯化和部分性质研究     舍蝇  凝集       font style='font-size:12px;'> 2007/12/24
摘要 舍蝇蛹体液经抽提后上Sepharose 4B亲和层析柱纯化制得舍蝇凝集素。制剂经聚丙烯酰胺凝胶电泳和在SDS-PAGE上均呈单一蛋白带,表观分子量为33400。它能凝集人B型红细胞,亦能凝集小白鼠及兔血红细胞。其专一结合的糖为半乳糖与D-及L-岩藻糖。
系统研究了敏感家蝇Musca domestica Vicina L.羽化后不同天数其头部乙酰胆碱酯酶(AChE)的比活力、敏感度以及酶源蛋白质含量的变化;缓冲液pH值对家蝇头部AChE比活力的影响。结果表明:家蝇初羽化至羽化后第15 d,其头部AChE的比活力逐渐升高 ,而酶源蛋白质的含量逐渐下降(187.022 2±9.021 3~83.022 2±7.111 1 μg/头)。羽化后2~4 d,...
Estimation of DDT by GLC (gas liquid chromatography) in the PCSIR strain of Musca domestica L. Shows that 59.69 ng/fly DDT was found in the sample extracted with hexane and 55.74 ng/fly in the sample ...
Toxicity of neem extract in comparison with DDVP (Dichlorvos) was determined against the housefly ( Musca domestica L). Neem leaf extract was applied at 5, 10, 20, 40 and 80 microgram/fly and DDVP was...
In most strains of the common housefly, Musca domestica, sex is genetically determined by the presence or absence of a Y chromosome with a dominant male determining factor, M. Standard trains have an ...
