ABSTRACT Three species of the family Phytoseiidae (Acari: Mesostigmata), Amblydromalus limonicus (Garman and McGregor), Neoseiulus fauveli (Athias-Henriot), and Typhlodromips sessor (De Leon), are reported for the first time from Turkey. The newly recorded species are redescribed and illustrated based on material collected from poplar trees, Populus spp. (Salicaceae), in Samsun Province on the Black Sea coast. Amblydromalus limonicus and T. sessor are mainly known from the Americas and are unexpected findings on poplar trees, as well as in the Turkish fauna. The third species, Neoseiulus fauveli, is known only from its original description from France. However, important morphological features, including dorsal setae lengths, cheliceral dentition, measurements, and the shape of macrosetae on legs, that are currently used to discriminate phytoseiid species, were missing in its original description. The presence of N. fauveli on Populus nigra L. in the present study is not surprising as many other species in the desertus species group of the genus Neoseiulus have been reported from species of Populus.
摘要：首次在土耳其报道了三种Phytoseidae（Acari：Mesostimata）、Amblydromalus limonicus（Garman and McGregor）、Neoseulus fauvelli（Athias Henriot）和Typhlodromips sessor（De Leon）。新记录的物种是根据从黑海沿岸萨姆森省的杨树杨属（杨柳科）收集的材料重新描述和说明的。柠檬Amblydromalus limonicus和T.sessor主要产于美洲，是在白杨树和土耳其动物群中意外发现的。第三个物种，Neoseulus fauveli，仅从法国的原始描述中得知。然而，重要的形态学特征，包括背刚毛长度、螯齿列、测量值和腿上巨大刚毛的形状，目前用于区分植物eiid物种，在其原始描述中缺失。在本研究中，N.fauveli在黑杨上的存在并不令人惊讶，因为据报道，新叶杨属的许多其他物种都来自黑杨。

ABSTRACT Ticks are haematophagous ectoparasites that infest all domestic animals and humans. They gain medical and veterinary significance due to the variety of aetiological agents that they can transmit. Acaricides have played a pivotal role in tick control until the surge of resistance to most of the commonly employed acaricides. Alternate tick control strategies have since gained significant attention and semiochemical assisted tick control is one such strategy. Herein, we attempted to employ an eco-friendly strategy to lure and kill ticks. Sustained-release microparticles in the form of porous calcium alginate beads incorporating the attraction sex pheromone, 2,6-DCP, and tulsi oil were prepared, and their efficacy was assessed using petri-dish bioassay. There was 100% mortality of the larvae and partially fed males exposed to these microparticles after 24 hours of exposure.

ABSTRACT A new feather mite species of the genus Trouessartia Canestrini, 1899 (Analgoidea: Trouessartiidae) is described from Myiophobus fasciatus (Statius Muller, 1776) (Passeriformes: Tyrannidae) in Brazil. Trouessartia apodemata sp. nov. differs from previously described species of the genus by the unique arrangement of epimerites around the genital apparatus in males, with the lateral tips of the epiandrum fused with epimerites IIIa anterior to the genital apparatus and epimerites IVa fused at their inner tips into a large arch posterior to it. http://www.zoobank.org/urn:lsid:zoobank.org:pub:A0B4C7DA-5E13-4487-8D4C-CA976FEFCB59 http://www.zoobank.org/urn:lsid:zoobank.org:act:32143DF9-A583-4472-B0F9-06AD2C306441

ABSTRACT The anti-tick efficacy of eight commercially available essential oils (EOs), viz., Neem (Azadirachta indica), castor (Ricinus communis L.), lemon grass (Cymbopogon flexuosus), eucalyptus (Eucalyptus globulus), curry leaves (Murraya koenigii), garlic (Allium sativum), sage (Salvia officinalis), and rosemary (Rosmarinus officinalis), was screened in vitro against Rhipicephalus microplus ticks. Each of the EOs were diluted in 2% Triton X-100 and 10% ethanol to prepare working concentrations and were tested against IVRI-I strain of Rhipicephalus microplus. The mortality, egg masses, and inhibition of oviposition (IO) were used to determine treatment effectiveness. The EOs of C. flexuosus, E. globulus, S. officinalis, and R. officinalis showed more than 95% efficacy at the tested concentrations. While, EOs of A. indica, R. communis, M. koenigii, and A. sativum were found 16–33% efficacious. Six different combinations of the most effective EOs (C. flexuosus and E. globulus) were prepared and tested for anti-tick activity. The combination C, F, and H showed 100% mortality at 4% concentration. The combination H was found more economical than ivermectin for animal treatment indication that it can be used effectively for the development of potent antitick formulation for the management of tick populations.

ABSTRACT The acute and long-term effects of two insecticide-acaricides, a mixture of spiromesifen + abamectin (S + A) and a terpenoid blend QRD 460 (TBQ), on the predatory mite Amblyseius swirskii were investigated. In acute-effect studies, the field recommended dose (T) of S + A and TBQ was applied to 0–24 hours old larvae and adults using direct application or dry residue methods. The sublethal effects of S + A and TBQ on the biological properties of A. swirskii were also investigated. Both pesticides used in acute effects were found to be harmless to A. swirskii based on the IOBC classification. The lifespans of female A. swirskii individuals in the control, S + A, and TBQ groups were 26.18, 22.64, and 23.73 days and 29.28, 20.50, and 25.47 days for male individuals, respectively. Oviposition duration was 19.59, 18.31, and 17.89 days in control, TBQ, and S + A groups, respectively. The mean number of eggs was 31.72, 26.61, and 26.00 eggs/female in control, S + A, and TBQ-treated individuals, respectively. The two most important parameters of the life table, R0 and rm values, were 31.72 females/female and 0.200 females/female/day for the control, respectively. According to the laboratory results of this study, S + A mixture formulation and TBQ have potential for use in integrated pest management in combination with the beneficial A. swirskii mite. However, the effects of these pesticides on A. swirskii should also be determined in greenhouse and field conditions.

ABSTRACT Sensory neuron membrane proteins belong to a gene family of the human fatty acid transporter CD36, which is mainly involved in the recognition of fatty acids, cholesterol, and proteinaceous compounds in cells. The gene families of the olfactory system in Acari are still not clear. In this study, we identified four SNMPs in the storage mite, Tyrophagus putrescentiae (Schrank) (Astigmata: Acaridae), named as TputSNMP1–4, and then determined these TputSNMPs expression levels in different developmental stages. All the TputSNMPs exhibited higher expression levels in the protonymph, female and male adults. To gain insight into the SNMP gene family, we surveyed the genomes of 12 other arthropod species. The results revealed that the SNMP gene family was highly dynamic in Acari, originating from the independent origins of insect subfamilies that differed from the SNMP1 group but in proximity to the SNMP2 group.

ABSTRACT Dermatophagoides farinae is one of the most important allergens that cause allergic diseases and trigger serious harm to the human body. D.farinae is widely distributed, and the development of genetic markers and genetic information regarding the populations of this species are needed to establish control strategies. The aim is to develop a microsatellite marker and assess the genetic diversity and population structure of different populations of D. farinae. The genomic DNA of D. farinae was extracted and sequenced by NGS analysis. Microsatellite markers were identified and screened with MISA software. Primers were designed with Primer5.0 and screened by capillary electrophoresis detection. Genotyping was implemented with GeneMarker 2.2. Genetic diversity and population structure were analysed by related softwares. Twelve microsatellite markers detected 66 alleles in 256 individuals of D. farinae from 12 geographic populations. The average allele number (Na), effective allele number (Ne), observed heterozygosity (Ho), and expected heterozygosity (He) were 4.431, 2.610, 1.056 and 0.484, respectively. Genetic variation existed within populations and there was no correlation between geographic distance and genetic distance (Fst) (P = 0.160). Structure analysis showed D. farinae is largely divided into three groups. The genetic diversity of the geographical population of D. farinae is relatively high.

ABSTRACT Six species of mesostigmatid mites, Asca nesoica Athias-Henriot (Ascidae), Blattisocius tarsalis (Berlese) and Lasioseius aff. dentatus (Fox) (Blattisociidae), Onchodellus calcaratus (Koroleva) (Pachylaelapidae), Proctolaelaps bickleyi (Bram) (Melicharidae), and Zygoseius furciger (Berlese) (Rhodacaroidea) are recorded for the first time in Syria. Mites were collected from three localities at Latakia and Hama governorates during the period from 2013 to 2020. These new records increase the number of the Syrian species of Mesostigmata to 48 species, but many more species are yet to be discovered.

ABSTRACT The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) has an extensive host range and is the most important pest mite worldwide. Traditional control measures have on the application of the lethal dose of acaricides, thus underestimating the total effects of acaricides on the population dynamics. Our main objective was to evaluate whether it is possible to rely on sublethal concentrations of the pesticide to control mites without getting meaningful crop. To test this hypothesis, we used sublethal concentrations (including LC10, LC20, LC30) of cyflumetofen to see the impact on population parameters of T. urticae. The experiments were performed under laboratory conditions at 25 ± 2°C, 60 ± 5% relative humidity (RH), and a photoperiod of 16:8 (L: D) hours. Results were based on age-stage, two-sex life table analysis. The data showed that sublethal concentrations of the pesticide suppress fecundity, adult longevity (both female and male individuals), and the intrinsic rate of increase significantly. For example, the fecundity in the LC10, LC20, LC30 and control was 36.55, 42.26,and 57.96 eggs/female, respectively, showing significant differences. Similarly, the intrinsic rate of increase (r) are also significantly different between LC30 (r = 0.20) and the control (0.24). The data presented here raise awareness into mite control since using a lower pesticide concentration not only controls the pest population but also produces lower risk to the environment, consumers, and biocontrol agents. Therefore, one could infer that using sublethal concentrations of pesticides would be more beneficial to both the environment and consumers in the long run.
