    • 摘要: The absorption and fluorescence spectra of aqueous solution of several common pesticides (seed coating agent of soybean,benzal chloride,imidacloprid,and buprofezin) were studied,to provide an basis for detection of pesticide residue. The experimental results showed that the absorption rates of pesti-cides in the ultraviolet region were stronger than in visible light region,and the maximum absorption wave-length and the absorption rate of different pesticides were different. The absorption peaks of buprofezin lo-cated at 227. 5 nm and 285 nm. The absorption peaks of imidacloprid located at 210 nm and 269. 5 nm. The absorption peaks of benzal chloride located at 212,238. 5,317,331 nm. The absorption peaks of seed coating agent of soybean located at 226,284. 5,330,509 nm. Aqueous solutions of these four pesticides were able to produce fluorescence,and all of them had strong fluorescence characteristics. The fluores-cence peaks of buprofezin located at 354 nm and 680 nm. The fluorescence peaks of imidacloprid located at 352 nm and 676 nm. The fluorescence peak of benzal chloride located at 414 nm. The fluorescence peaks of seed coating agent of soybean located at 352 nm and 675 nm. Under the same excitation condi-tion,the fluorescence spectra of different pesticides had different strength and shape,so the category of pesticide could be distinguished by comparing the spectra.%研究了常用农药(大豆种衣剂、苄·二氯、吡虫啉、扑虱灵)水溶液的吸收光谱和荧光光谱,为农药残留检测提供依据。结果发现,农药在紫外区的吸收比可见区域强,不同种农药对应的最大吸收波长不同,吸收率也不同。扑虱灵吸收峰在227.5 nm、285 nm 处,吡虫啉吸收峰在210 nm、269.5 nm处,苄·二氯吸收峰在212 nm、238.5 nm、317 nm、331 nm 处,种衣剂吸收峰在226 nm、284.5 nm、330 nm、509 nm 处。这4种农药的水溶液均能够产生荧光,具有很强的荧光特性。扑虱灵的荧光峰在354 nm 和680 nm 处,吡虫啉的荧光峰在352 nm 和676 nm 处,苄·二氯的荧光峰在414 nm 处,种衣剂的荧光峰在352 nm 和675 nm 处。在相同激发条件下,不同农药的荧光光谱具有不同的强度和形状,可以通过对比光谱图定性判别农药的类别。

    • 摘要: 调节好温度和光照:丝瓜在整个生长期都要有较高的温度,生长适宜温度为20~24°C,果实发育适宜温度为24~28°C。15°C左右丝瓜生长缓慢,低于10°C生长受抑制。在管理中,白天大棚内温度应保持在25~30°C,夜间温度保持在18°C左右。在丝瓜抽蔓前,可利用草苫适当控制日照时间,以促进茎叶生长和雌花分化。

    • 摘要: Two insecticides,buprofezin(BPFZ) and pyridaben(PRDB) were separated from water sample by mixing thoroughly with a mixture containing CH3CN and CHCl3 and standing for 5 min in a centrifuge tube.After centrifuging for 5 min,the solvent CHCl3 was removed by evaporation under reduced pressure and the residue was taken up with 50 μL of mixed solvent of CH3CN and water(75+25),from which an aliquot of 20 μL was taken for HPLC analysis.Symmetry C18 column was used as stantionary phase and mixture of CH3CN and water(75+25) as mobile phase.UV detection at 238 nm was adopted in the determination.Linearity ranges were found between 2.0-100 μg·L-1(for BPFZ) and 1.0-100 μg·L-1(for PRDB).Values of recovery and RSD′s(n=5) found were in the ranges of 81.2%-99.2%,87.3%-100.7%,and 1.7%-8.3%,0.6%-9.1% respectively.%取水样置于离心管中,与含有三氯甲烷(萃取溶剂)的乙腈(分散剂)混合溶液充分混匀,静置5min,使水样中的扑虱灵和哒螨灵迅速富集于三氯甲烷液滴中,离心5min,下层三氯甲烷相经减压蒸干后,加入乙腈-水(75+25)混合溶液50μL溶解残渣,分取20μL溶液供高效液相色谱法分析。用Symmetry C18色谱柱作固定相,流动相为乙腈-水(75+25)混合溶液,检测波长为238nm。扑虱灵和哒螨灵的线性范围分别为2.0~100μg.L-1和1.0~100μg.L-1。回收率分别在81.2%~99.2%和87.3%~100.7%之间,相对标准偏差(n=5)分别在1.7%~8.3%及0.6%~9.1%之间。

    • 摘要: 用浸叶法和浸渍法测定了扑虱灵、蚊蝇醚对以棉花为寄主饲养的烟粉虱卵和若虫的生物活性.结果表明:扑虱灵对1龄和4龄若虫毒力的LC50值分别为1.3、128.8 a.i.mg/L,浓度为100~1600 a.i.mg/L的扑虱灵对0~1日龄卵孵化几乎无抑制作用;蚊蝇醚浸叶法和浸渍法使用对0~1日龄卵毒力的LC50值分别为0.0227、o.0011 a.i.mg/L,浓度为7.8×10-3~16.0 a.i.mg/L的蚊蝇醚对4龄若虫羽化几乎无抑制作用.用0.5、5.0 a.i.mg/L蚊蝇醚浸渍处理对3日龄以前的卵孵化具有很强的抑制作用,对3日龄以后的卵几乎无抑制作用;烟粉虱雌成虫接触10 a.i.mg/L的蚊蝇醚,48 h后转移到无药植株上,其对0~2、2~4、4~6日龄卵的孵化具有很强的抑制作用,孵化率分别为(8.3±2.3)%、(0.1±0.4)%、(7.5±9.7)%,而对6~8日龄卵无抑制作用.%The biological activities of buprofezin and pyriproxyfen on the nymphs and eggs of Bemisia tabaci on cotton host plants were determined by the methods of dipping the leaves and the egginfested leaves into buprofezin and pyriproxyfen diluents for 10 s. The results showed that the toxicity of buprofezin to the 1st instar and 4th instar nymphs was respectively 1.3 and 128.8 a. i. mg/L in LC50 ,and buprofezin diluent of 100 - 1 600 a.i. mg/L almost had no inhibiting effect on hatching of the 0 - 1-day-old eggs. The LC50 of pyriproxyfen to the 0 - 1-day-old eggs was 0. 0227 a. i. mg/L by dipping the leaves into pyriproxyfen diluent and 0.0011 a.i. mg/L by dipping the egg-infested leaves into pyriproxyfen diluent,and pyriproxyfen diluent of 7.8 × 10-3 - 16.0 a. i. mg/L almost had no inhibiting effect on emergence of the 4th-instar nymphs. Dipping the egg-infested leaves into pyriproxyfen diluent of 0.5 or 5.0 a. i. mg/L had a very high inhibiting effect on hatching of the 0 - 3-day-old eggs but little inhibiting effect on hatching of the over-3-day-old eggs. When the female adults were exposed to cotton plants treated with 10 a. i. mg/L pyriproxyfen for 48 h and then transferred onto the untreated plant leaves,the eggs oviposited by them were severely inhibited in hatching,with the hatchability being (8.3 ± 2.3) % for 0 - 2-day-old eggs, (0.1 ± 0.4) % for 2 - 4-day-old eggs and (7.5 ± 9.7) % for 4 -6-day-old eggs,while the 6 - 8-day-old eggs were not affected.

    • 摘要: 近年来,随着茶叶生产的发展,茶树假眼小绿叶蝉、黑刺粉虱、长白蚧发生为害上升,对茶叶优质高产影响较大。为控制上述害虫,我县普遍推广了扑虱灵、吡虫啉作为茶树上的防治药剂,对叶蝉、粉虱类害虫防治效果较好,但综合控制作用不甚理想,不能达到一药多治的目的,同时外销茶叶对扑虱灵的残留十分严格,从而制约着扑虱灵的应用推广。

    • 摘要: [目的]探讨选择性农药是否是稻纵卷叶螟再猖獗的诱导因素.[方法]在盆栽和田间试验中,以武运粳7号为供试水稻品种.分别采用不同浓度的25%扑虱灵和10%吡虫啉对稻纵卷叶螟2龄和4龄期的幼虫进行喷雾处理,研究这2种选择性农药对稻纵卷叶螟产卵的影响.[结果]在稻纵卷叶螟幼虫2龄期用扑虱灵300.0、112.5、60.0g/hm2进行喷雾处理能刺激稻纵卷叶螟成虫产卵;在稻纵卷叶螟幼虫4龄期用吡虫啉60.0g/hm2喷雾处理也能刺激稻纵卷叶螟成虫产卵,并且其成虫产卵量与对照相比显著增加.[结论]扑虱灵和吡虫啉能刺激稻纵卷叶螟成虫产卵,是稻纵卷叶螟再猖獗的诱导因素之一.
