Abstract

The greater wax moth considered one of the most worldwide-spread pests of the bee wax. This Study was designed to investigate the insecticidal activity of Carumcarvi, Eculaptus camaldulensis and Nigella sativa against 3rd larval instar of G.mellonellathrough laboratory screening. Five concentrations (5%, 7.5%, 10%, 12.5% and 15%) of each plant extract were used in this experiment. Mortality (%) was recorded after 24, 48, 72 and 96 hrs post treatment. The results showed C. carvi, E. camaldulensis and N.sativahave insecticidal activity against 3rd_ instar larvae of G. mellonella. The highest concentration (15%) caused 90% ,86.7% and 80% larval mortality after 96 hrs for C. carvi,E. camaldulensis and N.sativarespectively. The statistical analysis revealed that there is a significant difference (p< .001) between all treatments and control. The results also clearly demonstrate that the C. carvi are significantly more toxic than E. camaldulensis and N. sativa, whereas the LC50 values were 5.4% forC. carvi,6.0% for E. camaldulensis and 6.2% for N. sativa.

Carumcarvi L.(香菜)、Eculaptuscamaldulensisdehnh(红胶)和nigella Sativa(黑籽)对大蜡蛾的防治效果。Innaeus(鳞翅目Pyralidae):

大蜡蛾被认为是世界范围内最广泛的蜂蜡害虫之一。本试验通过室内筛选，研究了卡鲁卡维蝇、山竹竹和黑鬼对大黄蜂3龄幼虫的杀虫活性。试验采用5种浓度(5%、7.5%、10%、12.5%和15%)的植物提取物。分别在治疗后24、48、72和96小时记录死亡率(%)。结果表明，胭脂红、黄蜡和黄蜡对黄蜡螟3龄幼虫均有杀虫活性。最高浓度(15%)96 h后幼虫死亡率分别为90%、86.7%和80%。camaldulensis和n .sativa分别。经统计学分析，各治疗组与对照组比较差异有统计学意义(p< 0.001)。结果还清楚地表明，胭脂草的毒力显著高于黄颡鱼和黄颡鱼，LC50值为5.4%。camaldulensis为6.0%，sativa为6.2%。
