Diptera: Culicidae
Liu et al. Parasites & Vectors 2011, 4:221 http://www.parasitesandvectors.com/content/4/1/221 RESEARCH Open Access The abundance and host-seeking behavior of culicine species (Diptera: Culicidae) and Anopheles sinensis in Yongcheng city, people’s Republic of China Xiao-Bo Liu1†, Qi-Yong Liu1*†, Yu-Hong Guo1†, Jing-Yi Jiang2, Dong-Sheng Ren1, Guang-Chao Zhou2, Can-Jun Zheng4, Yan Zhang1, Jing-Li Liu1, Zhi-Fang Li1, Yun Chen1, Hong-Sheng Li2, Lindsay C Morton3, Hua-Zhong Li4, Qun Li4 and Wei-Dong Gu5,6 Abstract Background: The knowledge of mosquito species diversity and the level of anthropophily exhibited by each species in a region are of great importance to the integrated vector control. Culicine species are the primary vectors of Japanese encephalitis (JE) virus and filariasis in China. Anopheles sinensis plays a major role in the maintenance of Plasmodium vivax malaria transmission in China. The goal of this study was to compare the abundance and host-seeking behavior of culicine species and An. sinensis in Yongcheng city, a representative region of P. vivax malaria. Specifically, we wished to determine the relative attractiveness of different animal baits versus human bait to culicine species and An. sinensis. Results: Culex tritaeniorhynchus was the most prevalent mosquito species and An. sinensis was the sole potential vector of P. vivax malaria in Yongcheng city. There were significant differences (P < 0.01) in the abundance of both An. sinensis and Cx. tritaeniorhynchus collected in distinct baited traps. The relative attractiveness of animal versus human bait was similar towards both An. sinensis and Cx. -
The Dominant Anopheles Vectors of Human Malaria in the Asia-Pacific
Sinka et al.

The first publication examined the DVS from the Americas, with the second covering those species present in Africa, Europe and the Middle East. Here we discuss the 19 DVS of the Asian-Pacific region. This region experiences a high diversity of vector species, many occurring sympatrically, which, combined with the occurrence of a high number of species complexes and suspected species complexes, and behavioural plasticity of many of these major vectors, adds a level of entomological complexity not comparable elsewhere globally. To try and untangle the intricacy of the vectors of this region and to increase the effectiveness of vector control interventions, an understanding of the contemporary distribution of each species, combined with a synthesis of the current knowledge of their behaviour and ecology is needed. Results: Expert opinion (EO) range maps, created with the most up-to-date expert knowledge of each DVS distribution, were combined with a contemporary database of occurrence data and a suite of open access, environmental and climatic variables. -

Molecular Phylogeny of Anopheles Hyrcanus Group Members Based on ITS2 Rdna Yuan Fang, Wen-Qi Shi and Yi Zhang*
Fang et al. Parasites & Vectors (2017) 10:417 DOI 10.1186/s13071-017-2351-x RESEARCH Open Access Molecular phylogeny of Anopheles hyrcanus group members based on ITS2 rDNA Yuan Fang, Wen-Qi Shi and Yi Zhang* Abstract Background: The Anopheles hyrcanus group includes 25 species, and is widely distributed in the Oriental and Palaearctic regions. Several species within this group are vectors of malaria, lymphatic filariasis and Japanese encephalitis. It is difficult or impossible to identify cryptic species based on their morphological characteristics, with some closely related species of the Hyrcanus Group have similar adult morphological characteristics. Thus, their molecular identification has been an important complementary method to traditional morphological taxonomy. Methods: We used 461 ribosomal DNA (rDNA) internal transcribed spacer 2 (ITS2) sequences relating to 19 species to reconstruct the molecular phylogeny of the Hyrcanus Group across its range. In addition, we compared the performance of rDNA ITS2 to that of mitochondrial DNA (mtDNA) cytochrome c oxidasesubunit1gene(cox1) to assess the genetic divergence of Hyrcanus Group sibling species. Results: Based on Kimura’s 2-parameter (K2P) distance model, the average conspecific ITS2 divergence was 0.003, whereas sequence divergence between species averaged 0.480. Average ITS2 sequence divergences were almost 160 times higher among the Hyrcanus Group members than within each species. Two sets of sibling species, An. lesteri Baisas & Hu, 1936 and An. paraliae Sandosham, 1959; and An. sinensis Wiedemann, 1828, An. belenrae Rueda, 2005, and An. kleini Rueda, 2005, were resolved by ITS2. Each of these species was represented as an independent lineage in the phylogenetic tree. -
Genomic Analysis of Detoxification Supergene Families in the Mosquito Anopheles Sinensis
RESEARCH ARTICLE Genomic Analysis of Detoxification Supergene Families in the Mosquito Anopheles sinensis Dan Zhou, Xianmiao Liu, Yan Sun, Lei Ma, Bo Shen*, Changliang Zhu* Department of Pathogen Biology, Nanjing Medical University, Nanjing, Jiangsu, 210029, P. R. China * [email protected] (BS); [email protected] (CZ) Abstract Anopheles sinensis is an important malaria vector in China and other Southeast Asian coun- tries, and the emergence of insecticide resistance in this mosquito poses a serious threat to the efficacy of malaria control programs. The recently published An. sinensis genome and OPEN ACCESS transcriptome provide an opportunity to understand the molecular mechanisms of insecti- cide resistance. Analysis of the An. sinensis genome revealed 174 detoxification genes, Citation: Zhou D, Liu X, Sun Y, Ma L, Shen B, Zhu C (2015) Genomic Analysis of Detoxification Supergene including 93 cytochrome P450s (P450s), 31 glutathione-S-transferases (GSTs), and 50 Families in the Mosquito Anopheles sinensis.
