A preliminary survey of domestic rodent and the efficacy of bendiocarb, diazinon and pirimiphos-methyl insecticides to their fleas were carried out in Dakahlia Governorates (Aga, Meet-Ghamr, El-Senbellawen, Temi El-Amded, Beni-Abed, Dekernes, Nabarow, Talkha, Menia El-Nasr and El-Kordy). Rodent index (number of rodent/trap) and percentage frequency of drodent species were recorded from October 2010 to May 2011. The main rodent species found were the Norway rat, Rattus norvegicus, the grey-bellied rat, R. rattus alexandrinus, the white-bellied rat, R. r. frugivorus and the house mouse, Mus musculus. The rodent index at Beni-Abed, Nabarow, Meet-Ghamr, Dekernes and El-Kordy centers showed 0.46, 0.39, 0.34, 0.33 & 0.33, respectively, while Menia El-Nasr center showed the lowest (0.08). Aga, Talkha, El-Senbellawen, and Temi El-Amded centers showed moderate (0.25, 0.21, 0.2 & 0.16, respectively). The commonest flea species was the oriental rat flea, Xenopsylla cheopis, the mouse flea, Leptopsylla segnis, the dog flea, Ctenocephalides canis and the sticktight flea Echidnophaga gallinacea. The highest number of fleas was on R. norvegicus (Flea index=10.9) while lowest number was on Mus musculus (Flea index=0.1). X. cheopis was the highest frequency distributed for all domestic rodent species (60.9%), while, C. canis was the lowest (1.6%). The results showed that bendiocarb was effective (Lc50=0.389%) than diazinon (Lc50=1.039%) and pirimiphosmethyl (Lc50=2.056 %).
在达卡利亚省（阿加、梅特加姆尔、塞恩贝拉温、泰米阿姆德、贝尼阿卜德、德克内斯、纳巴罗、陶尔哈、梅尼亚纳斯尔和科尔迪）对家栖啮齿动物以及恶虫威、二嗪农和甲基嘧啶磷杀虫剂对其跳蚤的药效进行了初步调查。于2010年10月至2011年5月记录了啮齿动物指数（啮齿动物数量/捕鼠夹）和啮齿动物种类的出现频率。发现的主要啮齿动物种类有褐家鼠、黑腹鼠、黄胸鼠和小家鼠。贝尼阿卜德、纳巴罗、梅特加姆尔、德克内斯和科尔迪中心的啮齿动物指数分别为0.46、0.39、0.34、0.33和0.33，而梅尼亚纳斯尔中心的指数最低（0.08）。阿加、陶尔哈、塞恩贝拉温和泰米阿姆德中心的指数为中等水平（分别为0.25、0.21、0.2和0.16）。最常见的跳蚤种类有印鼠客蚤、缓慢细蚤、犬栉首蚤和禽角头蚤。褐家鼠身上的跳蚤数量最多（跳蚤指数=10.9），而小家鼠身上的跳蚤数量最少（跳蚤指数=0.1）。印鼠客蚤在所有家栖啮齿动物种类中的分布频率最高（60.9%），而犬栉首蚤的分布频率最低（1.6%）。结果表明，恶虫威比二嗪农（LC50=1.039%）和甲基嘧啶磷（LC50=2.056%）更有效（LC50=0.389%）。
