To what extent does salt (NaCl) affect Anopheles gambiae sensu lato mosquito larvae survival?
The effect of salt (NaCl) on Anopheles gambiae sensu lato (s.l.) mosquito larval breeding was ascertained under laboratory conditions. No larval mortality occurred when the Cl– concentrations were between 0.017 ppt (0.03 ppt salinity) and 7.371 ppt (13.25 ppt salinity). However, 9%, 24%, 73.5%, 91.5% and 99.5% larval mortality occurred at 10.828 ppt (19.49 ppt salinity), 16.069 ppt (28.95 ppt salinity), 18.739 ppt (33.77 ppt salinity), 32.587 ppt (58.82 ppt salinity) and 47.326 ppt (85.37 ppt salinity) NaCl concentrations respectively. The lower NaCl concentrations resulting in LC50, (lethal concentration for 50% larval mortality), LC90 (lethal concentration for 90% larval mortality), LC95 (lethal concentration for 95% larval mortality), and LC99 (lethal concentration for 99% larval mortality) were 23.12 ppt (41.19 ppt salinity), 24.91 ppt (44.42 ppt salinity), 27.76 ppt (49.56 ppt salinity) and 33.87 ppt (60.568 ppt salinity) respectively. The upper NaCl concentration resulting in LC50, LC90, LC95 and LC99 were 32.89 ppt (58.83 ppt salinity), 37.21 ppt (66.63 ppt salinity), 44.79 ppt (80.32 ppt salinity) and 63.76 ppt (114.55 ppt salinity) respectively. In conclusion, the level of water salinity may indicate the presence or absence of An. gambiae s.l. mosquito larvae and this information can be used for disease control purposes.
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.
