“…As a result, a more effective, environmentally friendly, and cost-effective method is the use of natural predators to control Aedes mosquitoes [27]. To control mosquito larvae, several countries use larvivorous sh directly, whereas in others, this approach is used as a part of an integrated vector management program [10]. The study was conducted to evaluate the larvivorous potential of D. rerio and Po.…”

“…The lack of effective vaccines or drugs against the serotypes (DENV serotypes 1-4) of the dengue virus continues to be a major challenge in controlling dengue epidemics. As a result, various traditional methods for dengue control are being used, with a focus on vector control and patient management [9,10]. Catching, applying mosquito repellent sprays, using insecticides, using bed nets, indoor residual sprays, and biocontrol agents are the most commonly used control methods [2].…”

“…Several countries use larvivorous sh directly to control mosquito vector larvae, while in others, this approach is used as part of integrated vector control programs. Although larvivorous sh are an easy way to manage vectors, native sh should be used instead to prevent any unwanted consequences from introducing new sh species into the local environment [10]. The introduction of exotic species leads to the decline and complete absence of endemic species in different parts of the world [2].…”

Background Several viral infections are transmitted by members of the genus Aedes (Diptera: Culicidae). This study was conducted to evaluate the predatory potential of Danio rerio Zebrafish (Cypriniformes: Cyprinidae) and Poecilia reticulata Guppy (Cyprinodontiformes: Poeciliidae) to control Aedes mosquito larvae and thereby manage dengue epidemics in a sustainable, and eco-friendly manner. Methods Under laboratory conditions, size-matched fish of each species were introduced into separate plastic containers containing 2 liters of tap water and 100 third instar larvae of Aedes. In addition, different prey combinations were used to assess the comparative predation potential of fish. Mosquito prey preferences were assessed using Manly’s preference index. Results Over 24-hours of laboratory conditions, a significant difference (p < 0.05) between the predatory efficiency of the studied fish species was reported where the predatory efficiency of D. rerio was higher than that of Po. reticulata. D. rerio showed significantly (p < 0.05) higher predation efficiency and prey preference for 2nd instar larvae and pupae of Aedes than Po. reticulata on the presence of alternative prey. Conclusions Based on predation efficiency and prey preference, this study suggests that D. rerio can be evaluated as an alternative species to Po. reticulata in biological control as a more eco-friendly, low cost, and sustainable method for the management of Aedes mosquitoes.

“…One of the prevalent ideas during several decades has been to use natural predators to destroy immature populations of A. aegypti. Predators such as larvivorous fishes (The biocontrol efficacy of six larvivorous fish species, namely, Poecilia reticulata, Rasbora daniconius, Aplocheilus dayi, Oriochromis mossambicus, Oreochromis niloticus, Puntius bimaculatus) and other similar species were tested in experimental conditions [21], another predator: Larvae of Toxorrhynchites sp. was also identified as effective at reducing larvae of A. aegypti.…”

Dengue fever is a disease transmitted by the mosquito aegypti. There is a secondary vector: Aedes albopictus with some epidemiological importance in the transmission of dengue. Pharmacological treatment for dengue is a palliative treatment for the disease and there is an absence of a universally accepted vaccine for the different clinical infections. In these circumstances, the interruption of the infection cycle is possible basically through the reduction of the Aedes aegypti, reducing its breeding sites or physically reducing its population through chemical or biological means. Traditional approaches to vector control are becoming less effective as a result of the combination of resistance to insecticides and the logistic complexity of covering increasingly large urban centers with the same number of health workers as in past decades. Experiences in different countries reflect the need to involve more actively families and communities in the reduction of breeding sites. Several innovations have been introduced using biological methods, physical control of sources, and involvement of families and schools in vector control. The possibility to scale up successful experiences requires a joint effort of governments and communities to tackle mosquito source reduction and add a multipurpose concept of domestic hygiene.

“…In several studies it was also known that buckets, refrigerator water containers, dispenser containers as potential places for mosquito larvae with a positive correlation [14], but the presence of fish [15] and draining once a week [16] and the provision of temefos negatively correlated [17]. Some fish that are known to eat larvae include: Poecilia reticulata, Rasbora daniconius, Aplocheilus dayi, Oriochromis mossambicus, O. Niloticus and Puntius bimaculatus [18]. The variables included in the multivariate analysis were those with a significance value of<0.25; which are the type of container, presence of fish, drained in the last one week, temephos and material, and color of the container as shown in Table 5.…”

Dengue has been reported in Indonesia since1968; the cases tend to increase and spread every year. From 2015-2019 almost all districts in Indonesia had dengue cases. This study aimed to determine the value of the entomological index and its relationship with the treatment of various types of containers and spatial epidemiology. A larval survey was conducted to determine the presence of larvae in water containers. Logistic regression and spatial data analysis were performed to see the distribution and make a buffer area map of Aedes sp. spreading risk. The types of containers observed in this study were water tubs, drums, buckets, refrigerator containers, dispenser containers, and other categories. There were 221 containers found containing Aedes sp. larvae. Container types affected the presence of larvae with adjusted ORs of 2.779 (95% CI: 1.441-5.360) on buckets, 9.812 (95% CI: 1.249-77.051) on refrigerator holders, and 0.301 (95% CI: 0.147-0.617) on dispenser holders, while the other variables were constant. The spatial analysis found that many houses are at risk of dengue transmission within a radius of 100 m. The discovery of containers as potential breeding sites for Aedes sp. provides a chance for an increase in dengue cases in Samarinda.
