Abstract

Abstract Considering the harmful effects of the synthetic termiticides and resistance development in the pest population, there is a need to search for economically viable, environmentally-friendly and effective termiticides. Therefore, the screening of alternative antitermiticidal activity from plant based products could be employed as a means in the termite control strategies. The present study was carried out to evaluate the anti-termitic activity of the hexane leaf extract of Prosopis juliflora against the termites of Macrotermes spp. at concentrations of 25, 50, 75 and 100 mg/L. It was found that, the LC50-LC90 values were 33.3–213.98, 12.71–66.33 and 9.41–34.71 mg/L after 24, 48 and 72 h of exposure, respectively. The phytochemical study of the crude extract showed the presence of steroids, saponins, terpenoids, alkaloids and flavonoids which might be responsible for its biocidal activity. These results suggested that hexane leaf extract of P. juliflora possessed biocidal activity aginst termites.

黄豆叶提取物对大白蚁(等翅目:白蚁科)灭蚁活性的初步评价

摘要考虑到合成白蚁杀虫剂的有害影响和害虫种群的抗性发展，有必要寻找经济可行、环保有效的白蚁杀虫剂。因此，从植物产品中筛选替代的抗白蚁活性可以作为白蚁控制策略的一种手段。本研究旨在评价25、50、75和100 mg/L浓度下，丝叶正己烷叶提取物对大白蚁的抗白蚁活性。研究发现，暴露24、48和72小时后，LC50-LC90值分别为33.3–213.98、12.71–66.33和9.41–34.71 mg/L。粗提取物的植物化学研究表明，其存在的甾体、皂苷、萜类、生物碱和黄酮类化合物可能是其具有杀生物活性的原因。结果表明，正己烷叶提取物对白蚁具有一定的杀灭活性。
