Effects of two insect growth regulators on the protein level and RNA intensity in the larvae of camel nasal bot fly, Cephalopina titillator (clark, 1797) (Diptera: Oestrjdae) [electronic resource].

Includes references.

Cephalopina titillator (Family: Oestridae) is a serious pest for camels because it is an obligate parasite. C. titillalor has two generations during the year. The flies deposit their larvae in the nasal cavity of camels where the larvae cause extensive damage of nasopharyngeal tissues before leaving the infested camel to pupate in sand (Zumpt, 1965 and Derhalli et al., 1989). Recently, it was found that the infection by larvae of the nasal bot fly causes changes in neurotransmitters of serum and different brain regions and also decreases thyroid hormones of the thyroid gland (Al Sagair et al., 2004 and El-Bassiony et al., 2004) Controlling this serious pest was achieved by using the systemic organophosphates (Ashetova, 1987 and Ergahev et al., 1987), especially ivermectin which proved to be effective against C. titillator (Lumsden et al., 1992 and Sharma, 1992). Disadvantages of using ivermectin are the lengthy preslaughter withdrawal period and that it should not be used in lactating animals (Jackson, 1989).
