“…Their use in different countries, modes of action, and resistance mechanisms are summarized in Tables 1 and 2. Selection of highly resistant individuals may be facilitated by the use of off-label medicines, when inadequate treatment regimens are upheld, or when drugs with long half-lives are utilized [17]. It may be argued that national imposed treatment thresholds are an important factor for resistance selection.…”

“…This result disagreed with the result of diazinon 15% (4ml/l) in the current study as mortalities of adult ticks started at 7 th day post treatment and the highest efficacy (86.6%) was achieved at 14 th day post treatment (the end of the experiment). The resistance of hard ticks to diazinon insecticide was also recorded by Li et al, (2003), Miller et al, (2008), Fernández-Salas et al, (2012 and Alonso-Díaz et al, (2013). The rational explanation of this variation in results may be due to the continuous use of the same insecticide for long period that lead to resistance development by ticks.…”

“…The continued usage of the same compound for controlling certain insect for long period resulted in developing resistance against the used compound. Many publications documented the resistance of hard tick species to Diazinon; Li et al, (2003), Miller et al, (2008), Fernández-Salas et al, (2012 and Alonso-Díaz et al, (2013) and deltamethrin; Brito et al, (2011), Sharma et al, (2012 and Shyma et al, (2015).So, the current trend in the world now is the use of natural products to overcome the drawbacks of currently used chemicals. In the last decades, plant extracts were widely used against phytophagus pests and mosquitoes (Balandrin et al, 1995).…”

Key words:Comparison, Butox ® , Diazinon, Achook, Acaricidal ActivityCommercially available preparations including Butox ® 50% (containing 5% deltamethrin), Diazinon 15% and Achook 0.15% (containing 0.15% Azadirachtin) were compared for their acaricidal activity against Rhipicephalus (Boophilus) annulatus engorged females obtained from naturally infested cattle from Rashid city, Behera Province, Egypt, and other developmental stages using immersion test. It was found that the highest mortality (86.6%) was achieved by using Diazinon 15% and Achook at concentrations of 4 ml/l and 0.15%, respectively. The complete inhibition of oviposition was observed when using Butox ® 50% and diazinon 15% at all used dilutions while Achook caused drop in reproductive index (RI) of tested females reached 75% at concentration of 0.075%. On the other hand, the bioassays on eggs and larvae revealed the superior effect of Achook over Butox ® 50% and Diazinon 15%; as the lowest hatchability (0%) of eggs and highest mortality (100%) within the first 24 hours post treatment on unfed larvae was achieved in Achook at both concentrations of 0.15% and 0.075% azadirachtin. Finally, it was concluded that Butox ® 50%, Diazinon 15% and Achook 0.15% commercially available pesticides showed variation in percentages of adult tick and larval mortalities, inhibition of oviposition and hatching of laid eggs. Promising results of Achook which is a product for agricultural use and does not have recommended dose for veterinary application yet needs further investigations to be recommended.

“…The colony of A. mixtum provides an opportunity to produce a continuous supply of ticks for further research on their biology, role as a vector of disease agents, and control technologies. This is especially important in parts of North America where A. mixtum is a vector of veterinary and public health importance, including Mexico, where laboratory colonies are not available (Gonzalez-Ceron et al 2009;Illoldi-Rangel et al 2012;Alonso-Diaz et al 2013).…”

Life cycle of Amblyomma mixtum (Acari: Ixodidae) parasitizing different hosts under laboratory conditions

Amblyomma mixtum is a tick species in the Amblyomma cajennense complex. The known geographic range of A. mixtum extends from Texas in the USA to western Ecuador and some islands in the Caribbean. Amblyomma mixtum is a vector of disease agents of veterinary and public health importance. The objective of this study was to describe the life cycle of A. mixtum under laboratory conditions. Bovines, rabbits and sheep were infested with larvae, nymphs, and adult ticks under controlled conditions to assess several biological parameters. Eggs, larvae, nymphs and adults were kept in an incubator (27 °C temperature and 80% relative humidity) when they were off the host. The average life cycle of A. mixtum was 88 and 79 days when fed on rabbits and cattle, respectively. Sheep were found to be unsuitable because no ticks attached. The rabbit is a more practical host to maintain a colony of A. mixtum under laboratory conditions. The data from this study can be considered as an example for the life cycle of A. mixtum. However, caution must be exercised when making comparisons to the biology of A. mixtum in its natural habitat.
