Chemical composition and bioactivity of Vitex cofassus Reinw. extracts on the larval and pupal stages of Aedes aegypti

Abstract

Aims and Objectives: This study sought to investigate the chemical composition, larvicidal, and cytotoxic potentials of the fruit extract of Vitex cofassus Reinw. Materials and Methods: The chemical composition was analyzed using the gas chromatography–mass spectrometry technique. Separately, mortality data were evaluated by probit analysis to determine the lethal concentration (LC) 50 and LC 90 values on brine shrimp and Aedes aegypti larvae. Moreover, the effects on different stages of Ae. aegypti were also examined. Results: Fourteen majority components representing carboxylic acid were identified. The extract was very toxic to both brine shrimp and Ae. aegypti larvae with LC 50 values of 0.308 and 0.514 µg/mL, whereas the LC 90 values were 4.317 and 1.921 µg/mL, respectively. The effect of the fruit extract of V. cofassus on different stages of Ae. aegypti indicated that high concentrations (2.00–4.00 µg/mL) promoted complete mortality. A concentration of 0.125 to 1.00 µg/mL inhibited larval metamorphosis. Conclusion: To the best of our knowledge, this is the first study to evaluate the chemical composition and larvicidal effects of the fruit extract of V. cofassus . The results indicate that the extract may be a promising source of larvicidal compounds that could be useful for pharmaceutical applications.

Bioefficacy of Extracts Isolated From Vitex-Sp [ White and Violet Flower] and Anethum Graveolens [Dill] Against Eggs and Pupal Stages of Culex Pipiens [Diptera: Culicidae].

“…Furthermore, mortality in the pupal stage and damage to adult emergence was increased proportionally with the increase in the use of concentration (Aziz et al, 2016, Nirupama et al, 2018Trilokesh et al, 2019 andLukman et al, 2021).…”

PENYAKIT BERCAK DAUN PADA BIBIT BITTI (Vitex cofassusReinw.) DI PERSEMAIAN

“…Harga jual kayu bitti di tingkat petani di Sulawesi Tenggara berkisar 1,3-2,8 juta/m3 dan merupakan komoditas ekspor (Adrianto et al, 2015). Selain itu buah bitti merupakan bahan bio insektisida karena memiliki kandungan bahan aktif untuk mengendalikan perkembangbiakan nyamuk Aedes aegypti (Muslimin et al, 2020) Pembangunan hutan tanaman bitti di Sulawesi perlu mempertimbangkan aspek pengadaan benih/bibit berkualitas, manipulasi lingkungan dan pengelolaan hama dan penyakit secara terpadu (Onyekwelu, Stimm, & Evans, 2011). Bitti termasuk jenis yang telah dilaporkan terserang oleh agen-agen penyebab penyakit tanaman.…”
