Abstract
Mosquitoes of the genus Culex are crucial vectors of numerous
diseases, which includes lymphatic filariasis, Japanese encephalitis, and West
Nile fever. The enormous use of artificial pesticides has caused environmental
worries and the improvement of insecticide resistance, necessitating the look
for green options. The observes evaluated the larvicidal hobby of aqueous
extracts of onion (Allium cepa), garlic (Allium sativum), and
papaya (Carica papaya) against Culex mosquito larvae at
one-of-a-kind concentrations (10%, 20%, 50%, 70%, 90%, and 100%) and publicity
periods (1, 6, 12, 18, and 2 hours). Larval mortality multiplied with each
attention and publicity time for all extracts. Garlic extract exhibited the
best larvicidal hobby, reaching whole mortality (100%) at 90% and 100%
concentrations inside 1 hour of publicity. Papaya extract confirmed slight
effectiveness, even as onion extract verified relatively decrease larvicidal
hobby. Mean mortality values ranged from 1.50 ± 0.80 to 5.00 ± 0.00 for garlic,
2.50 ± 0.91 to 3.80 ± 0.45 for papaya, and 1.80 ± 0.79 to 0.10 ± 0.45 for onion
extracts. Two-manner ANOVA discovered full-size results of each attention (F =
5.156, p = 7.01 × 10⁻⁷) and publicity time (F = 55.838, p = 6.71 × 10⁻²⁴) on
larval mortality. The findings suggest that plant-primarily based totally
extracts, especially garlic, own robust larvicidal capacity and might function
environmentally secure options for the manipulate of Culex mosquito
populations.
