The sweetpotato whitefly, Bemisia tabaci, has been a destructive pest in China for over the past two decades. It is an extremely polyphagous insect, being recorded feeding on hundreds of host plants around the world. Potential host plants and natural enemies of B. tabaci in the south, southeast, middle, north and northwest of China were investigated during the last decade. In total 361 plant species from 89 families were recorded in our surveys. Plants in the families Compositae, Cruciferae, Cucurbitaceae, Solanaceae and Leguminosae were the preferred host species for B. tabaci, which therefore suffered much damage from this devastating pest due to their high populations. In total, 56 species of parasitoids, 54 species of arthropod predators and seven species of entomopathogenic fungi were recorded in our surveys. Aphelinid parasitoids from Encarsia and Eretrnocerus genera, lady beetles and lacewings in Coleoptera and Neuroptera were found to be the dominant arthropod predators of B. tabaci in China. The varieties of host plant, their distribution and the dominant species of natural enemies of B. tabaci in different regions of China are discussed.

烟粉虱内共生菌初步研究

烟粉虱内共生菌初步研究

华东、华南和西南地区烟粉虱的种群及寄主分化(英文)

通过对烟粉虱体内共生菌的检测表明,烟粉虱体内的共生菌可分为:初生内共生菌,肠杆菌科次生共生菌,Wolbachia属细菌,杀雄菌,拟杆菌门的Cardinium和类噬胞细菌,衣原体门细菌,立克次氏体等7类。本研究中,国内14个省区、巴基斯坦、新加坡以... 详细信息

通过对烟粉虱体内共生菌的检测表明,烟粉虱体内的共生菌可分为:初生内共生菌,肠杆菌科次生共生菌,Wolbachia属细菌,杀雄菌,拟杆菌门的Cardinium和类噬胞细菌,衣原体门细菌,立克次氏体等7类。本研究中,国内14个省区、巴基斯坦、新加坡以及马来西亚的47个烟粉虱种群中初生共生菌、杀雄菌、Cardinium三种内共生菌的检出结果:初生共生菌总体检出率为39.0%,在B型烟粉虱种群内检出率为26.7%,在非B型烟粉虱种群内检出率为48.1%;杀雄菌总体检出率为46.8%,在B型烟粉虱种群内检出率35.0%,在非B型烟粉虱种群内检出率为55.6%;第一次利用PCR扩增技术从烟粉虱体内扩增出了Cardinium16S rDNA基因350bp序列,Cardinium总体检出率为9.2%,在B型烟粉虱种群内检出率为6.7%,在非B型烟粉虱种群内检出率为11.1%。结果表明:在非B型烟粉虱种群中初生共生菌和次生共生菌的感染率均高于在B型烟粉虱种群的感染率,这可能与B型烟粉虱的强大的入侵能力有关。对以上烟粉虱的三种内共生菌基因序列,分别构建了系统进化树,表明烟粉虱种群的各内共生菌是有遗传进化的,并且据此推测内共生菌的遗传进化可能是由于烟粉虱的基因组成的遗传进化所引起的。

烟粉虱Bemisia tabaci是一个复合种,它具有的生物型分化、较强的传播病毒的能力和抗药性、较快的繁殖速率等特征使其成为我国农业生产中重要害虫之一。本研究利用细胞色素线粒体氧化酶Ⅰ基因,对采集自江苏、广东和云南三省的烟粉虱样本进行了生物型鉴定,并对烟粉虱生物型与寄主植物之间的关联性开展了调查。结果表明,在广东和云南省,都存在未鉴定的土著种群与入侵的B型、Q型共存的现象;同时,在本研究中广东省尚未采集到Q型烟粉虱,而在江苏采集到的粉虱样本全部为入侵型。研究结果还表明,相对于入侵种而言,土著种群显示出更强的寄主植物趋同性;丰富的寄主植物以及本身具有的多食性特性有助于B型、Q型等生物型在世界各地的广泛入侵。

In practical applications,relative humidity in the air is a key factor affecting the photocatalytic removal of NO,which is often overlooked in previous ***,we developed a direct z-scheme UiO-66-NH2/Bi2MoO6heterojunction with a nanoflower-like structure to systematically investigate the effect of relative humidity on photocatalytic removal of *** optimized heterojunction for the removal efficiency of NO was 71.6% at1.07 mg·m-3NO concentration（relative humidity=10%）,and the generation of NO2was only 1.1%.Interestingly,with the increase in relative humidity,it showed a higher inhibition effect on NO2,while the removal of NO decreased slightly（8%）,which might be attributed to the affinity effect of NO2with water molecules and the competitive adsorption of H2O and NO on the surface of the heterojunction ***,the reaction pathways of NO removal at the developed heterojunctions were revealed by in situ DRIFTS *** work provides a novel vision for the development of direct z-scheme heterojunction photocatalysts to effectively remove NO and inhibit the formation of toxic intermediate NO2under different humidities.
