Control of mosquito larvae in the port city of Assab by an indigenous larvivorous fish, Aphanius dispar

Background and purpose: Mosquitoes are responsible for the transmission of many pathogens such as malaria, yellow fever, dengue fever, and so on. The control of mosquitoes using chemical insecticides is not always a sensible approach, so, alternative biological control methods, especially the use of larvivorous fishes, can play a significant role in controlling of mosquito larvae. Materials and Methods: In this narrative review study, papers and dissertations were collected without time and language limits from international electronic databases in Google Scholar, PubMed, ScienceDirect, Web of Science, Ovid, Medline and WHO site, and Iranian scientific databases including: Barakatkns, SID, Civilica, Magiran, and Medlib using appropriate keywords from 1937 to 2018. Finally, 55 sources were selected and criticized, interpreted, and analyzed. Results: In the study, some of larvivorous fishes including Aphanius dispar, Carassius auratus (goldfish), Gambusia affinis, and Poecilia reticulate (guppy) have been investigated as important predators of mosquito larvae. Among these fish, Gambusia, Aphanius dispar, Colisa Lalia, Danio rerio, Goldfish, Guppy and Oreochromis mossambica are present in different regions of Iran. Conclusion: Given the fact that malaria carriers are present in many regions of Iran and the climate of Iran is also potentially suitable for the transmission of malaria, it is recommended to use larvivorous fishes that are compatible with the environmental conditions of each area.

Jenynsia Multidentata

ABSTRACT Larvivorous fish have been studied as potential biocontrol agents of mosquito larvae and pupae through their trophic interactions. The use of native ﬁsh for mosquito control may have beneﬁts for both aquatic biodiversity and human health. Evaluating the effect of vegetation on the predatory efficacy is fundamental to determine if this species can be used as a biocontrol agent. With the aim of evaluating Jenynsia multidentata (Jenyns, 1842) as a biocontrol agent of Culex pipiens Linnaeus, 1758, we tested its predatory capacity in the presence or absence of aquatic vegetation under laboratory conditions. Two independent experiments were conducted. Larval consumption at a density of 60 larvae (6 larvae/l) was significantly reduced with the vegetation increased. On the other hand, when the larval density was 120 (12 larvae/l), the predatory capacity of J. multidentata did not vary in the presence or absence of vegetation. This result indicated that vegetation effect on consumption could be related to prey density, since at the higher density of prey the probability of predator-prey encounter might be increased. Jenynsia multidentata is a good consumer in presence of vegetation and could be used as a potential biocontrol agent of mosquito larvae in natural environments with similar characteristics to the ones tested in these experiments.

Local larvivorous fish Aphanius dispar has potential for regulating vector mosquitoes. The consumption of larvae of the mosquito Culex quinquefasciatus Say (Diptera: Culicidae) by Rasbora daniconius, Puntius ticto and Puntius conchonius was evaluated in the presence of different prey densities under simple habitat conditions. The number of mosquito larvae consumed in fresh and ditch water at three seasons was observed. Only third and fourth instars of Culex larvae were used on a particular prey density of 1 to 10 (increase 100). The maximum and minimum value of larvae eating per day in ditch and fresh water were observed to 267 to 876 and 277 to 880 respectively. The comparisons for the pair using Tukey-Kramer HSD indicated the fact that there was non-significant difference. The respective mean values in fresh and ditch water were observed 525 and 493 respectively. The analysis of water (ditch and fresh) was nonsignificant (F = 1.0116). Rasbora daniconius species of fish played a dominating role in eating the Culex larvae in ditch and fresh water.

Study to assess the larvicidal property of Lantana camara leaves against Aedes triseriatus larvae found that the ethyl acetate extract had profound larvicidal action with the crude extract having a LC50 value of 409.831ppm. GC-MS analysis of the ethyl acetate extract confirmed the presence of twenty-one compounds out of which beta-caryophyllene covered the highest percentage of the chromatogram area. Further tests with beta-caryophyllene against the mosquito larvae proved it to be the active ingredient of L. Camara with a LC50 value of 104.243ppm.
