Costs and effectiveness of application of Poecilia reticulata (guppy) and temephos in anopheline mosquito control in river basins below the major dams of Sri Lanka

The larvivorous potential of Poecilia reticulata was studied in the laboratory and in the field. In the laboratory, the number of anopheline larvae consumed per fish per day and the number of larvae in fecal matter per fish were determined. In the field study, 29 of 60 selected riverbed pools in Kotmale oya, below the Kotmale dam, were stocked with P reticulata, whereas the rest served as controls. Anopheline larval surveys were carried out starting from 1 day prior to stocking of fish and on selected days subsequently. P. reticulata consumed an average of 117 ± 32.33 larvae per fish per day. Fecal matter of P. reticulata contained an average of 2.7 ± 2.68 larvae per fish . There was a significant reduction in the number of pools positive for anopheline larvae ( P < .001) after stocking fish and the number of larvae per pool ( P < .001) and per 100 dips ( P < .001) as compared with controls.

Introduction: Due to its colors, shape, size, and simplicity of care, the neotropical fish Poecilia reticulata (guppy) is popular in the aquarium trade. It is also valued as mosquito control and is now found in most of the world. Objective: To report its presence in southern Mexico. Methods: Fish were captured with seine nets in a tributary of the Grijalva River, Chiapas, in August 2019, and March 2020. Results: Two hundred and fifty individuals of P. reticulata were captured. Conclusion: The species, found in México in 1971, has extended its range to the Grijalva Usumacinta river system.
