Experiments were performed investigating citronella (Cymbopogon winterianus Jowitt) as a repellent to honeybee Apis mellifera (L.) (Hymenoptera: Apidae) in Egypt, it was conducted in laboratory in the Department of Entomology and Pesticides Science, Faculty of Agriculture, Cairo University, to check long-term survival of honeybee when exposed to different nano insecticides alone or combined with citronella at the same examination box for each. In this study, we used a modeling approach regarding survival data of caged worker bees under chronic exposure to four insecticides (Chloropyrophos, Nano-chloropyrophos Imidacloprid, Nano-Imidacloprid) each of them was supplemented in a box alone and in combination with citronella. Having three replicates and five concentrations (100, 200, 300, 400 and 500 ppm). Laboratory bioassay of these insecticides showed that chloropyrophos and nano chloropyrophos were the most toxic at their high dose (500 ppm) with LT50 of 120.98 and 122.02 followed by 132.14 and 136.5 minutes for Imidacloprid and Nano-Imidacloprid, respectively. No consumption occurred by bees to mixed sugar syrup with insecticides in all treatments when citronella was added. These data highly recommended that adding citronella is very effective when nicotinoid pesticides are used to longevity honeybee life and keep bee safe.

用香茅油保护蜜蜂（蜜蜂）的某些杀虫剂及其纳米制剂

在埃及开罗大学农学院昆虫学和农药科学系的实验室中进行了香茅（Cymbopogon winterianus Jowitt）作为蜜蜂对蜜蜂Apis mellifera（L.）（膜翅目：Apidae）的驱避剂的研究。在单独的不同纳米杀虫剂中或与香茅一起在相同的检查箱中检查蜜蜂的长期存活率。在这项研究中，我们使用了一种建模方法，将笼养工蜂在长期暴露于四种杀虫剂（氯吡咯啉，纳米-氯焦磷，吡虫啉，纳米-吡虫啉）下的存活数据进行了单独补充，并与香茅一起在盒子中进行了补充。具有三个重复和五个浓度（100、200、300、400和500 ppm）。这些杀虫剂的实验室生物测定表明，氯吡咯磷和纳米氯吡咯啉在其高剂量（500 ppm）时毒性最高，LT50为120.98和122.02，其次是吡虫啉和纳米吡虫啉的132.14和136.5分钟。在添加香茅油的所有处理中，没有蜜蜂食用糖浆和杀虫剂的混合物。这些数据强烈建议，在使用烟碱类农药延长蜜蜂寿命并保持蜜蜂安全时，添加香茅油非常有效。在添加香茅油的所有处理中，没有蜜蜂食用糖浆和杀虫剂的混合物。这些数据强烈建议，当使用烟碱类农药延长蜜蜂寿命并保持蜜蜂安全时，添加香茅油非常有效。在添加香茅油的所有处理中，没有蜜蜂食用混合糖浆和杀虫剂的情况。这些数据强烈建议，在使用烟碱类农药延长蜜蜂寿命并保持蜜蜂安全时，添加香茅油非常有效。
