摘要

在疟疾流行地区实施工业项目之前,应收集基本昆虫学资料。这样就可以对项目对疟疾病媒的影响进行后续监测和评价。这项研究旨在评估南喀麦隆森林集团中两个生态不同的村庄的病媒系统和疟疾传播,目标是建立一个农工综合体。在2013年连续四个季节,在NDELLE村(位于有许多鱼塘的退化森林中的一条主干道旁)和KOMBO村(位于距离主干道5公里的较暗森林中,Mvobo河穿过)使用人类着陆捕捞法捕获了成蚊。形态分类技术与分子技术共同用于蚊虫种类鉴定。采用ELISA法检测恶性疟原虫环孢子子蛋白抗原。NDELLE的蚊虫叮咬率高于KOMBO(28.18对17.34)。NDELLE(73.57%)和KOMBO(70.21%)的蚊类均有较强的自噬倾向。鉴定出按蚊3种;一个。冈比亚,安。funestus s.s和An。moucheti轮. .一个。冈比亚和安哥拉。以funestus s.s.为主要攻击蚊种(n=10,891);96.62%)。一个。冈比亚在KOMBO和NDELLE的疟疾传播率分别为62.6%和77.72%。KOMBO和NDELLE的昆虫学平均接种率分别为4.82和2.02个/人/夜。病媒控制主要基于使用长效杀虫蚊帐和室内滞留喷洒。森林环境的退化和鱼塘的存在导致侵略性蚊子密度的增加,但没有导致疟疾传播。管理人员应使用这些数据来监测和评价其项目的影响;应将疟疾控制战略纳入其项目,以减轻由于实施其项目而增加疟疾传播的风险。

Aggressive mosquito fauna and malaria transmission in a forest area targeted for the creation of an agro-industrial complex in the south of Cameroon
Baseline entomological information should be collected before the implementation of industrial projects in malaria endemic areas. This allows for subsequent monitoring and evaluation of the project impact on malaria vectors. This study aimed at assessing the vectorial system and malaria transmission in two ecologically different villages of the South-Cameroon forest bloc targeted for the creation of an agro-industrial complex. For four consecutive seasons in 2013, adult mosquitoes were captured using Human Landing Catch in NDELLE village (located along a main road in a degraded forest with many fish ponds) and KOMBO village (located 5km far from the main road in a darker forest and crossed by the Mvobo River). Morpho-taxonomic techniques were used alongside molecular techniques for the identification of mosquito species. ELISA test was used for the detection of circumsporozoite protein antigen of Plasmodium falciparum . Mosquito biting rate was higher in NDELLE than in KOMBO (28.18 versus 17.34 bites per person per night). Mosquitoes had a strong tendency to endophagy both in NDELLE (73.57%) and KOMBO (70.21%). Three anophelines species were identified; An. gambiae , An. funestus s.s and An. moucheti s.s.. An. gambiae and An. funestus s.s. represented the bulk of aggressive mosquitoes in NDELLE (n=10,891; 96.62%). An. gambiae was responsible for 62.6% and 77.72% of malaria transmission in KOMBO and NDELLE respectively. Mean entomological inoculation rate recorded in KOMBO and NDELLE were 4.82 and 2.02 infective bites per person per night respectively. Vector control was mainly based on the use of long-lasting insecticidal nets and indoor residual spraying. The degraded forest environment added to the presence of fishponds resulted in the increase of aggressive mosquito density but not of malaria transmission. The managers should use these data for monitoring and evaluation of the impact of their project; malaria control strategies should be included in their project in order to mitigate the risk of increased malaria transmission as a result of the implementation of their projects.

期刊介绍: The Journal of Entomological and Acarological Research (JEAR), formerly the Bollettino di Zoologia Agraria e di Bachicoltura of the Institute of Entomology of the Università degli Studi, Milano, was founded in 1928 by Remo Grandori. Thereafter, Minos Martelli and Luciano Süss hold the direction of the Journal until December 2011. In January 2012 the Editor decided for the new open-access on-line version of JEAR. The Journal publishes original research papers concerning Arthopods, but reviews, editorials, technical reports, brief notes, conference proceeding, letters to the Editor, book reviews are also welcome. JEAR has four main areas of interest: -Entomology (systematics; morphology; biology; biotechnology; agriculture, ornamental and forest entomology; applied entomology; integrated pest management; biological control; apiculture and apidology; medical, urban and veterinary entomology; etc.) -Stored product pests (biology; integrated pest management; etc.) -Insect Ecology (behaviour; biodiversity; taxonomy; plant insect interaction and ecosystems; biological control; alien species; etc.) -Acarology (systematics; morphology; biology; parasitology; control; etc.) The publication of manuscripts is subject to the approval of the Section Editor who has knowledge of the field discussed in the manuscript in accordance with the principles of Peer Review; referees will be selected from the Editorial Board or among qualified scientists of the international scientific community. Articles must be written in English and must adhere to the guidelines and details contained in the Instructions to Authors.
