Larvicidal potential of Pseudomonas mosselii isolated from Aedes (Diptera: Culicidae) egg surfaces against dengue vector mosquitoes and its impact on non-target organisms

The critical impact of mosquito-borne diseases on public health, along with the failure of current control strategies, highlights the need for novel mosquito control approaches, especially in tropical countries. This study explored the larvicidal properties of bacterial isolates from the egg surfaces of Aedes aegypti L. and Aedes albopictus Skuse (Diptera: Culicidae), the primary and secondary dengue vector mosquitoes in Sri Lanka.
Among 30 bacterial isolates, a local strain of Pseudomonas mosselii Quesnel, isolated from the egg surfaces of dengue vectors, demonstrated strong larvicidal activity against Ae. aegypti. Larvicidal assays using the bacterial supernatant (OD 1.7) and freeze-dried products were performed across concentrations ranging from 80 to 2.1 mg/mL. The LC50 values for the supernatant were 55, 54, and 52 mg/mL at 24, 48, and 72 h, respectively, with corresponding LC90 values of 91, 89, and 86 mg/mL. Freeze-dried supernatant showed LC50 values of 2.73, 2.64, and 2.63 mg/m..., , # Data from: Larvicidal potential of Pseudomonas mosselii isolated from Aedes (Diptera: Culicidae) egg surfaces against dengue vector mosquitoes and its impact on non-target organisms

## Description of the data and file structure

This dataset collection presents the raw experimental data underlying laboratory bioassays that evaluated the mosquitocidal potential of Pseudomonas mosselii against dengue vector mosquitoes (Aedes aegypti and Aedes albopictus), as well as its effects on two non-target aquatic organisms (Culex quinquefasciatus and ostracods). The study assessed three formulations of the bacterial treatment, namely, cell-free supernatant (CFS), freeze-dried cell-free supernatant (FDCFS), and freeze-dried bacterial culture (FDBC), with treatment concentrations expressed in mg/mL. Each test concentration was replicated four times, along with four distilled water controls. Each dataset is provided in .csv format.
