ABSTRACT The interaction relationships of a binary mixture of spirodiclofen, fenpyroximate, and etoxazole acaricides, and mixing each of these acaricides with imidacloprid were investigated on deutonymph of Tetranychus urticae using the Potter spray tower method under controlled laboratory conditions. Based on the results of bioassay tests and combination index (CI) estimates, the toxicity of the binary mixture of the tested acaricides with each other and with imidacloprid on T. urticae was lower than that of each compound alone, and the interaction of their binary mixture was the antagonistic type. The measurement of the activity level of detoxifying enzymes in T. urticae treated with the LC50 concentration of pesticides and their binary mixture showed that the highest α- and β-esterase and glutathione S-transferase (GST) activities were observed in mites treated with spirodiclofen. Additionally, the highest cytochrome P450 monooxygenases (MFO) content was detected in mites treated with a mixture of spirodiclofen and imidacloprid. The results indicated that the application of a binary mixture of the mentioned acaricides together and in combination with imidacloprid leads to inefficient control of T. urticae.

ABSTRACT Tapirs are common hosts of ticks and an individual can be infested by up to seven different tick species. We explored the parasitic tick fauna associated with wild Baird’s tapirs (Tapirus bairdii) from the Yucatan Peninsula. A total of 326 ticks of 10 species of the Family Ixodidae were collected from 15 tapirs. We found a range of one to six tick species per host, but most of the tapirs were parasitized by two or three tick species. We tested the relationship between body condition, sex, and age classes of the tapirs versus the number of tick species on each host. The most common tick species was Amblyomma mixtum found on 93% of the hosts. Amblyomma pecarium, Amblyomma tenellum, Ixodes affinis and Rhipicephalus sanguineus sensu lato were recorded for the first-time parasitizing Baird’s tapirs. We did not find a relationship between body condition, sex, and age classes of tapirs versus the number of parasitizing tick species. Our finding demonstrates that the richness of ticks parasitizing tapirs does not depend on the biological characteristics and health status of the host, but could be determined by other factors such as habitat use and the rate of contact with domestic animals.
摘要：Tapirs是蜱虫的常见宿主，一个个体最多可感染七种不同的蜱虫。我们探索了与尤卡坦半岛野生贝尔德貘（Tapirus bairdii）相关的寄生蜱类动物群。从15头貘身上采集到10种硬蜱326只。我们发现每个宿主有一到六种蜱虫，但大多数貘都被两三种蜱虫寄生。我们测试了貘的身体状况、性别和年龄等级与每个宿主上蜱虫物种数量之间的关系。最常见的蜱种是在93%的宿主身上发现的Amblyomma mixtum。记录了首次寄生在贝尔德貘身上的黄曲霉（Amblyomma pecarium）、黄曲霉（Amblyomma tenellum）、亲缘硬蜱（Ixodes affinis）和血红Rhipipcephalus sangeus sensu lato。我们没有发现貘的身体状况、性别和年龄等级与寄生蜱虫物种数量之间的关系。我们的发现表明，寄生在貘身上的蜱虫的丰富度并不取决于宿主的生物学特征和健康状况，而是可能由其他因素决定，如栖息地的使用和与家畜的接触率。

ABSTRACT The aim of this study is to explore the detoxification and homoeostasis functions of salivary glands, and to look for possible target proteins of new drugs for tick prevention and treatment. Different concentrations of chlorpyrifos to deal with the semi-engorged female Haemaphysalis longicornis, through the DIA quantitative proteomics method to quantitatively determine of all the proteins in the salivary glands, and through a variety of the depth of the bioinformatics methods for protein analysis and function mining, explain the molecular mechanism of detoxification function of salivary glands. Quantitative information from 5 normal groups and 8 different treatment groups showed that a total of 3152 proteins were identified. The expression levels of these proteins changed with the chlorpyrifos different concentration and treatment times. However, after the overall analysis, it was found that after the action of chlorpyrifos, the proteins involved in detoxification, such as glutathione S-transferase and glutamine synthetase, the heat shock proteins involved in stress, and the acid sphingomyelinase involved in maintaining the body’s homoeostasis had corresponding changes. We found and explained the functions of detoxification, stress, and homoeostasis of salivary glands. The regulatory strategies of proteins that played a key role in these functions were explored.

ABSTRACT The life table parameters and predation rate of Typhlodromus bagdasarjani Wainstein & Arutunjan (Phytoseiidae) fed on Eotetranychus frosti (McGregor) (Tetranychidae) nymphs reared on four apple cultivars Kohanz Golab, Imperial Gala, Lebanon Red, and Granny Smith were studied under laboratory conditions. The longest developmental time of immature stages in females was observed on Kohanz Golab, and the shortest one was on Granny Smith. The fecundity ranged from 27.28 eggs on Golab Kohanz to 41.98 eggs on Granny Smith. The highest and lowest intrinsic rate of increase (r) were obtained on Granny Smith (0.254 day-1), and Kohanz Golab (0.136 day-1), respectively. The total prey consumption by all immature stages on Kohanz Golab, Imperial Gala, Lebanon Red, and Granny Smith was 36.93, 29.93, 27.36, and 21.30 prey, respectively. The total prey consumption by adult females was 424.70±24.41 prey on Kohanz Golab, 327.39±18.50 prey on Imperial Gala, 289.77±17.42 prey on Lebanon Red, and 218.50±14.64 prey on Granny Smith. The lowest fecundity and intrinsic rate of increase as well as the longest total life span of the predator on the resistant cultivar (Kohanz Golab) to E. frosti showed that integrated use of resistant cultivars and phytoseiid mites for control of spider mites needs more investigations.

ABSTRACT The ecology of chigger mites has many unknown aspects, even with several recent studies addressing the taxonomy and systematics of this group. In Brazil, the chigger species recorded coparasitizing vertebrates include opossums in the Pernambuco State, lizards and rodents in the Piauí State, and rodents in the São Paulo State. Chiggers collected on a domestic cat, Felis catus Linnaeus, 1758 (Mammalia: Felidae), from Caxias do Sul, Rio Grande do Sul State, were sent to the Acarological Collection of Instituto Butantan (IBSP) to be identified. The species were identified as eight larvae of Eutrombicula tinami, two larvae of Parasecia valida Brennan, 1969, and two specimens of the genus Eutrombicula Ewing, 1938, which have been described here as Eutrombicula bassinii n. sp. Additionally, we amplified partial 18S rRNA gene sequences for E. tinami and E. bassinii n. sp. However, the attempts to amplify fragments of the gltA gene of Rickettsia were unsuccessful. The present study reports the coparasitism in a domesticated feline with these three species, the second record of E. tinami, the first record P. valida to the Rio Grande do Sul State, and the description of E. bassinii n. sp. http://www.zoobank.org/urn:lsid:zoobank.org:act:D0D6EEAB-DDB6-49F0-9651-4AFB96D4D588

ABSTRACT Tetranychus gloveri, a recently introduced mite species in Kerala, India has now established in the state as a predominant mite pest on ornamental plants. In this study, the status of acaricide resistance and the activity of detoxification enzymes were investigated in the populations of T. gloveri collected on Adenium plants from six different commercial horticultural nurseries of Thrissur district, Kerala, India. Adulticidal bioassays were performed for fenazaquin and dicofol, while nymphicidal bioassays were conducted for spiromesifen to estimate the LC50. The field populations showed resistance ratios in the range of 1.66–14.38-fold for fenazaquin, 1.06–27.31-fold for spiromesifen and 1.22–3.65-fold for dicofol, compared to the laboratory-maintained reference population. Enzyme assays of detoxifying enzymes revealed enhanced activity of carboxylesterase by 1.03–3.52-fold and cytochrome P450 monooxygenase by 1.01–2.08-fold in the field populations. However, the role of glutathione S-transferase in the development of resistance in different field populations was insignificant. The study recorded the development of resistance in the spider mite, T. gloveri to new generation acaricides spiromesifen and fenazaquin for the first time and also confirmed the significant role of the carboxylesterases and cytochrome P450 monooxygenases in imparting resistance in T. gloveri.
