Efficacy of flumethrin and coumaphos against the camel tick Hyalomma dromedarii L. (Acari: Ixodidae).

The efficacy of Flumethrin pour on and Coumaphos 50% WP was tested against different stages of Hyalomma dromedarii. With contact method, LC50 values for larvae and adults were 0.04, 0.03 ug/cm2 and 0.05, 1.06 ug/cm2 respectively. The LC50 for coumaphos against the larvae, adults and eggs using dipping method were 44, 63, and 62 ppm respectively. Flumethrin caused significant reduction in oviposition and hatchability in female ticks that survived sublethal concentrations, while sublethal doses of coumaphos had no effect on the reproductive potential of the tick. The results showed that flumethrin was 8 times more toxic than coumaphos.

Study on the effect of Bacillus thuringiensis (B.t. serotype H-14) and its toxins against Cephalopina titillator (Clark), the Egyptian camel myiasis producing dipterous fly.

Bacillus t. israelensis (B.t. serotype H-14) and its toxins have a marked lethal effect on both the eggs and the newly moulted 3rd stage larvae of Cephalopina titillator. The Bacillus was less effective than Bacillus and its toxins on both the eggs and larvae. On the other hand, the larvae were more affected by both Bacillus and Bacillus and its toxins than the eggs. Prolonged exposure time showed more lethal effect.
