“…In the laboratory, these fish species are used to reduce the number of mosquito larvae. The present findings are consistent with those of earlier research reports in various ecosystems conducted by Datta et al, 2022 [29] ; Tilak et al, 2007 [26] ; Câmara et al, 2017 [27] ; Sumithra et al, 2014 [28] and Gupta et al, 2009 [30] . The results of the present study make it clear that all four species of fish prefer live food, particularly mosquito larvae, than artificial food, and that this preference is substantially greater than that of other fish species (Table-3; Table-5; Fig- 5; Fig- 6).…”

Aedes aegypti and Aedes albopictus are the carriers of a variety of diseases such as dengue, dengue hemorrhagic fever (DHF), chikungunya, zika virus, and yellow fever. An affordable way of vector management that effectively suppresses the mosquito population for a long time is the release of larvivorous fish. In this work, ornamental fish species are identified, and their potential larvicidal efficacy for biological control of Aedes mosquito larvae is assessed. The consumption rates of four ornamental fish species (Gold fish, Betta fish, Molly fish, and Guppy) for Aedes aegypti and Aedes albopictus larvae have been observed in the present study, and a comparison between the mean consumption rates of the four fish species for Ae. aegypti and Ae. albopictus has been recorded. The observation indicated practically no variance, and the intake rates for both types of larvae were almost same for the four species of fish. In contrast to guppy fish, the findings indicated that Goldfish, Black molly, and Betta fish had very high feeding rates. Therefore, in the near future, these fish can be thought of as efficient biological control agents for both Aedes aegypti and Aedes albopictus larvae.

“…Earlier studies [26] suggested that ornamental fishes specially Gold fish exhibit excellent larvivorous potentials to control mosquito population. Recently in our laboratory similar findings [23,24] were well documented. Furthermore, Mannaa et al, (2008) [27] in his observation suggested that Poecilia reticulata can consume 65-84 IV instar Culex larvae in a period of 3 hours.…”

Aedes albopictus is a potential vector that is responsible for severe outbreaks of dengue and DHF. Implementing traditional methods such as insecticides and mosquito repellents are harmful to the environment and to human health. In the present study, the rate at which Aedes albopictus larvae were consumed as well as the other feeding preferences of five ornamental fishes (Guppy, Molly fish, Betta fish, Gold fish, and Angel fish) were noted and compared. While Molly fish, Fighter, and Guppy considerably prefer Aedes albopictus larvae over the other food item, Gold fish and Angel fish exhibit good efficacy toward both types of food. In the last decade of little works (use of ornamental fish) have been done to control Aedes mosquito population. Therefore, a preliminary attempt has been undertaken to include ornamental fishes as vector controlling agent.

“…30 For a fish to be used as a mosquito biocontrol agent, it must meet two basic criteria: First, it must have a high predation efficacy on mosquito larvae; second, it must be resistant to low oxygen concentrations while also being toxic metabolite tolerant. 31 In future research, it is expected that the potential of rosy barb fish needs to be tested on other species of mosquito larvae. Larvivorous fish for Aedes aegypti in the field are still rarely found.…”

Introduction:The control program for Dengue Hemorrhagic Fever (DHF) outbreaks prioritizes controlling the mosquito vector population. One way of biologically controlling mosquitoes that is safer and more environmentally friendly is fish as natural predators of larval and pupae stage mosquitoes. One fish tested in this study was Rosy Barb (Pethia conchonius). Objective: This study aimed to compare the male and female fish predation ability of rosy barb (P. conchonius) in Aedes aegypti larval and pupal stages. Methods: This study is a laboratory experiment with a post-test-only design and five replications. One aquarium holds one litre of water, one fish, and 25 Ae. aegypti larval/pupa tails. Fish testing begins at 09.00 WIB in the morning. Fish predation was timed until the fish consumed all larvae and pupae. Results:The mean time of predation of male P. conchonius to larvae was 12.03 minutes, and pupae were 2.83 minutes. The mean time of predation of female P. conchonius on larvae was 11.70 minutes, and pupae were 4.28 minutes. The results of the independent sample t-test equal variance assumed statistical test showed that male and female fish had mosquito larvae feeding times that were not significantly different (p> 0.05). Male and female fish had mosquito pupa feeding times that were not significantly different (p > 0.05). Conclusions: Rosy barb fish (P. conchonius) has the potential as a natural predator of Ae. aegypti larval and pupal stages.
