Phytotoxic Potentials of some Plants Extracts Against Southern House Mosquito (Culex quinquefasciatus SAY)
Keywords:
Culex quinquefasciatus, instar larvae, Lantana camara, crude extract, mortalityAbstract
Six (6) plant species were screened for larvicidal potentials against the larvae of Southern house mosquito, Culex quinquefasciatus. The plants included Hyptis lanceolata, Hyptis suaveolens, Hyptis spicigera, Lantana camara, Cymbopogon citratus and Zingiber officinale. Crude extracts were obtained in different solvents using Soxhlet extractor. Their larviciding activity was investigated by immersion and batches of 20 instar larvae were treated with 62.5, 125, 250, 500, and 1000mg/l of the plant extracts after 96 hours exposure, for 5 days and in three replicates. Extracts that did not cause mortality at 62.5mg/l necessitate the use of higher concentrations (1500 and 2000 mg/l). Control treatment consists of 1ml acetone in distilled water. Results revealed that all the 6 plants exhibited varying larvicidal activity. L. camara showed highest percentage mortality (63.20%) at the least concentration of 62.5mg/l. This was followed by H.
