查询词典 larvicide

However, laboratory and field experiments show that mosquitoes can produce binary toxin resistance under a long-term high selective pressure, which compromises Bs products as a biological mosquito larvicide in the comprehensive prevention and control of vectors and mosquitoes.

但实验室以及野外实验表明，蚊虫在长期高选择压力下能对二元毒素产生抗性，蚊虫对Bs产生的抗性影响了其作为生物杀蚊幼制剂在蚊虫综合防治中的持效应用。

It is valuable and practicable to adopt the strategy of the integrated mosquito control in the city. For example, health education is conducted to all people by government, their own mosquito breeding sites are cleared away by the urban residents themselves, the mosquito breeding sites in the public places are cleaned up and the larvicide is used in permanent breeding sites by pest control operators.

采取政府机构开展人群的健康教育、居民清除自家的各种蚊幼孳生地、专业除害队伍清除公共地段的蚊幼孳生地，并对无法清除积水的区域投加灭蚊幼缓释剂的蚊虫综合治理策略，可在城市灭蚊工作中推广应用。

Gravid An. sinensis demonstrated significant negative taxis towards bacteria A4 and Aeromonas sp., as well as slight taxis to Enterobacter sp., implying that the three bacteria were not the dietary preference for An. sinensis. However, in light of the possibility of their stable colonization into mosquito's guts, these strains may serve as the host cells of larvicide genes and transgenic anopheline antimalarial genes.

中华按蚊产卵时对A4菌和气单胞菌具有明显的负趋性，而对肠杆菌仅具有微弱的趋向性，推测这3种细菌可能不是中华按蚊食物的优先选择，但具有在蚊中肠内较为稳定存活的可能性，因此更适合于作为蚊幼生物杀虫基因的寄主细胞和仿转基因按蚊抗疟基因的寄主细胞被应用。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
