The acaricidal effect of peracetic acid against Boophilus annulatus and Argas persicus

Abstract

The acaricidal activity of peracetic acid, PAA, against the cattle tick, Boophilus annulatus, and the fowl tick, Argas persicus was tested using filter paper contact bioassay. PAA had a great potential as acaricide and its effectiveness increased with increasing concentration and exposure time. Two minutes after treatment with 0.5%, PAA induced 100% mortality of both tick species and LC50 values for cattle and fowl ticks, after treatment for 30 min, were 0.06 and 0.05%, respectively. Following treatment with 0.25%, the LT50 values were 0.02 and 3.12 min, respectively. Furthermore, the detrimental effect of PAA against cattle tick extended beyond the adult stage, it significantly prolonged the preoviposition period, shortened the oviposition period, and decreased the mean number of the layed eggs, such parameters were 14.75 and 6.57 days, as well as 457.50, respectively, after treatment with 0.25% of PAA. Therefore, PAA is highly effective when used at lower doses and short exposure time. The high speed of killing ticks is very important for avoidance of the hazard ensued by pathogen transmission in the course of delayed mortality caused by the currently used acaricides.A atividade acaricida do ácido peracético, PAA, contra os carrapatos bovinos Boophilus annulatus, de aves, Argas persicus foi testada pelo uso do sistema de filtro de papel. O PAA mostrou um grande potencial acaricida e os efeitos aumentaram com o aumento da concentração e tempo de exposição ao produto. Dois minutos após o tratamento com 0,5%, o PAA causou 100% de mortalidade em ambas as espécies. O valor de LC50 foram, respectivamente, 0,06 e 0,05%, para o tratamento de 30 minutos. O tratamento com 0,25%, teve um LT50 de, respectivamente, 0,02 e 3,12 min. Além disso, os danos causados pelo tratamento com 0,25% de PPA atingiram a fase adulta do carrapato, prolongando o tempo de pré-postura (14,75 dias), reduzindo o período de postura (6,57 dias) e número de ovos (457,50). Portanto, o PPA é altamente eficaz, mesmo quando usado em baixas doses e por curso períodos de exposição. A grande velocidade para matar os carrapatos é muito importante para evitar o perigo de transmissão de. Descritores: Boophilus annulatus, Argas persicus, acaricida, ácido peracético.

Novel Pesticidal Efficacy of Araucaria heterophylla and Commiphora molmol Extracts against Camel and Cattle Blood-Sucking Ectoparasites

“…A related study showed that the methanol extract of neem and Citrullus colocynthis produced an acaricidal effect against adult females, eggs, and larvae, and neem was more effective against H. dromedarii [72]. Some other materials are also effective in vitro acaricides such as peracetic acid against Boophilus annulatus and the fowl tick, Argas persicus [17] and A. persicus, infesting laying hens [18]. Moreover, some photosensitizers such as safranin and rose bengal had a strong acaricidal effect against H. dromedarii and suppressed the reproductive potential of its engorged females [16].…”

“…Some other approaches could be used for controlling pests, such as botanicals and biological control, vaccination, photopesticides, and acids [16][17][18][19][20][21][22][23]. Searching for alternative control strategies, mainly from plant-based resources, is a promising field [5].…”

Prevalence and risk factors associated with tropical theileriosis in Egyptian dairy cattle

“…Ticks are obligate hematophagous ectoparasites of humans and animals. They transmit more species of pathogens than any other blood-feeding arthropod [ 1 - 6 ] and require careful monitoring and control measures [ 7 , 8 ]. A variety of tick-borne diseases affect animal productivity in developing countries [ 9 ].…”

“…The mortality of larvae in all cups was followed up in the same day of treatment. Larvae were considered alive or dead according to larval motility (Khater and Ramadan, 2007;Khater et al, 2013). Larval mortality was determined daily until pupation occurred.…”
