The members of the families Rhodacaridae and Laelapidae are free-living mites, found mainly in litter and the first few centimeters of the soil surface, and sometimes near plant roots, where they feed on insect larvae, springtails, nematodes, and phytophagous mites. At present some members of these families have been considered for use in biological control programs of Rhizoglyphus mite species (Acari: Acaridae). The development and fecundity of Gaeolaelaps aculeifer (Canestrini) and Protogamasellopsis rhizoglyphusi Amin & Khanjani, feeding on the astigmatic mites Rhizoglyphus echinopus (Fumouze & Robin) (Acaridae) and Carpoglyphus lactis (L.) (Carpoglyphidae) were studied at 25 ± 1 ºC, 60 ± 10%, and in the darkness. The results showed that both predatory mites can feed and thrive on the two preys. Each predator species had a similar duration of the immature phase on both preys, and the duration was slightly longer for G. aculeifer (11.1–12.1 days) than for P. rhizoglyphusi (9.1–9.2). The oviposition time and life span were also similar for both species on both prey (respectively 17.7–19.8 and 35.9–39.8). However, the mean daily oviposition per female G. acullifer increased from about 2.9 eggs on R. echinopus to about 4.0 eggs on C. lactis. Also, the mean daily oviposition per female P. rhizoglyphusi decreased from about 3.8 eggs on R. echinopus to about 3.6 eggs on C. lactis. The net reproductive rate (R0) ranged between 29.9 and 36.3 ♀/♀, except for G. aculeifer on R. echinopus, only 19.0 ♀/♀. The values of intrinsic rate of increase (rm) ranged from about 0.136 ♀/♀/day (G. aculeifer feeding on R. echinopus) to about 0.230 (P. rhizoglyphusi feeding on C. lactis). Stage duration increased in starved specimens, G. aculeifer and P. rhizoglyphus adult females survived without food for a mean of 18 and 16.5 days, respectively. The results showed that mass rearing of both predators can be performed using C. lactis as prey, and also, both predators are able to develop and reproduce on R. ehinopus, a serious pest species in different countries, as prey. These data provide significant information for the practical application of predatory soil mites in the management of agricultural pests.

Taxonomy of the predatory mite family Phytoseiidae (Acari: Mesostigmata) is essentially based on morphological observations, and only a few studies use integrative approaches that include mainly morphological and molecular analysis. Species of the genus Euseius Wainstein (Acari: Phytoseiidae) are pollen feeding generalist predators belonging to “Type IV” group. There are more than 200 species of the genus that are considered to be valid. However, there could be a series of synonyms among these valid species. Euseius gallicus Kreiter & Tixier is one of the recently described species and its natural populations have been reported from a total of 10 countries. There are some molecular studies showing that E. gallicus represents a different lineage and separated adequately from the other well-known and common species, E. stipulatus in the Western Palearctic region. However, it shows great morphological similarities with E. amissibilis Meshkov, a species previously described from Tajikistan. According to its original description, these two species can be separated based on a few differences in their setal lengths, but doubts remain regarding the similarities between them. Therefore, we examined the type material of E. amissibilis, and newly collected materials from various localities including the type locality. We conducted molecular analyses, using two gene markers (ITS and Cox1) to determine whether these two species are conspecific. Results show that all morphological characters and measurements of the type and the newly collected materials of E. amissibilis fall within the range indicated in the original description of E. gallicus. Moreover, zero and low levels (≤6% previously considered as variation for phytoseiid mites) of genetic distances were detected among the specimens of these two species from different populations based on ITS and Cox1 gene markers, respectively. As conclusion, this study confirms that E. gallicus is a junior synonym of E. amissibilis. In addition, based on our best knowledge, a ventral pore-like structure located on ambulacral stalk of the first leg is observed for the first time in a species of the family Phytoseiidae, probably even in the order Mesostigmata.
捕食螨科（Acari: Mesostigmata）的分类主要基于形态学观察，只有少数研究采用了主要包括形态学和分子分析的综合方法。Euseius Wainstein 属（Acari：Phytoseiidae）的物种是以花粉为食的食肉动物，属于 "第四类"。该属有 200 多个物种被认为是有效的。不过，这些有效种中可能存在一系列异名。Euseius gallicus Kreiter & Tixier 是最近描述的物种之一，其自然种群已在 10 个国家被报道。一些分子研究表明，E. gallicus 代表了一个不同的品系，并与西古北地区另一个著名的常见物种 E. stipulatus 充分分离。然而，它与之前在塔吉克斯坦描述的 E. amissibilis Meshkov 在形态上有很大相似之处。根据最初的描述，这两个物种可以根据刚片长度的一些差异区分开来，但对它们之间的相似性仍然存在疑问。因此，我们研究了 E. amissibilis 的模式标本，以及从包括模式产地在内的不同地点新采集的标本。我们使用两个基因标记（ITS 和 Cox1）进行了分子分析，以确定这两个物种是否为同种。结果表明，E. amissibilis 的模式标本和新采集材料的所有形态特征和测量值都在 E. gallicus 原始描述的范围之内。此外，根据 ITS 和 Cox1 基因标记，这两个物种来自不同种群的标本之间的遗传距离分别为零和低水平（≤6%，以前认为这是植物螨类的变异）。作为结论，本研究证实 E. gallicus 是 E. amissibilis 的小异名。此外，据我们所知，位于第一腿伏胫柄上的腹腔孔状结构是首次在植食科的物种中观察到，甚至可能是在中形目中观察到。

Environmental influences experienced by organisms are known to influence the phenotype of offspring through transgenerational plasticity or parental effects, and recent studies have revealed the significance of diet stress experienced by parents in shaping the life course of their progeny. In this laboratory study using a predatory mite, Phytoseiulus persimilis Athias-Henriot, we investigated the influence of parental diet restriction on offspring life history traits. We found that parental mites exposed to food reductions of 50% (Low diet) during both immature development and adult stages produced F1 offspring with reduced survival rates and fecundity compared to those from parents on abundant (High) diets. Sexually dimorphic responses emerged in response to parental diet restriction, whereby a reduced diet led to extended developmental periods for both male and female offspring while simultaneously reducing male size at maturity and increasing female size at maturity. We also found that diet restriction experienced by F0 individuals at both immature and adult stages manifested as reduced egg volumes and a less female-biased sex ratio in the F1’s offspring (i.e. the F2). There were additional significant interactions between the dietary history of parents and the dietary experiences of P. persimilis offspring themselves on various traits, including post-oviposition period, fecundity, and individual egg volume. These findings suggest that the dietary experiences of parents can modulate their offspring’s response when facing diet restriction. This study provided insights into non-genetic inheritance and transgenerational plasticity, highlighting the intricate interplay between environmental stressors and phenotypic responses.

The physiological changes in Tetranychus urticae selected with spiromesifen+abamectin (S+A) mixture formulation were demonstrated by biochemical and molecular methods. The susceptible (GSS) population of T. urticae, was selected with S+A and made resistant with increasing doses of the mixture formulation. The resistant population was divided into two, and selection pressure was terminated in one population which is named IR (Interrupt resistant). In the other population, the selection with S+A was continued and the population named IR2. Activities of some detoxification enzymes (esterase, glutathione-S-transferase (GST) and cytochrome P450) were investigated in the GSS and IR populations. The activity of esterase, GST and P450 enzymes were increased by 1.77, 2.57 and 2.58-fold, respectively, in the IR population compared to the GSS population. Also, investigation of synergistic effects with esterase inhibitor (TTP), GST inhibitor (DEM) and P450 inhibitor (PBO) in this population revealed that all three synergists showed significant synergistic effects in IR population. In molecular studies, when the population was screened for the presence of two previously identified glutamate channel mutations (G314D and G326E) by qPCR with TaqMan probes no mutations could be detected in glutamate channels. and the CTD domain of acetyl coenzyme-A carboxylase (ACCase). Furthermore, possible genetic mutations in the biotin carboxylase domain (BCD) and carboxyl transferase domain (CTD) of the ACCase target sites were determined by sequencing. Although a single amino acid mutation G37D in the BCD of the ACCase gene of the IR and IR2 populations was detected, its association with spiromesifen resistance was not confirmed. The results indicated that increased detoxification and possible target site mutation may be responsible for the S+A resistance in the IR and IR2 populations.

This study presents a checklist and a key encompassing 11 species of Typhlodromus Scheuten (Acari: Phytoseiidae) from Syria, derived from materials collected in this study as well as previous reports. A brief redescription, including setal measurements and some other important characters used to discriminate phytoseiid species, is provided for each species examined. Notably, the species Typhlodromus (Anthoseius) intercalaris Livshitz & Kuznetsov is reported for the first time in Syria, and redescribed based on adult specimens collected from Quercus cerris L. and Quercus infectoria G. Olivier (Fagaceae) trees in Latakia governorate. The examined specimens of this species demonstrated variation in the presence or absence of preanal pores: (1) absent on both sides; (2) present on both sides; (3) present on the left side; and (4) present on the right side. This species was considered a junior synonym of T. (A.) invectus Chant in an earlier study without examination of their type materials. We tried to find the holotype T. (A.) invectus without success. However, according to their original description, T. (A.) intercalaris is distinguishable from T. (A.) invectus by having two pairs of setae on the sternal shield, as opposed to three pairs in the latter species. Therefore, the reason for the redescription provided here is to improve diagnosis and minimize any confusion regarding the species status of the Syrian specimens. This discovery holds significant implications for understanding the biodiversity of phytoseiids in the country.
本研究提供了一份核对表和一把钥匙，其中包括来自叙利亚的 11 种 Typhlodromus Scheuten（蛔虫：Phytoseiidae），这些材料来自本研究收集的材料以及以前的报告。对所研究的每个物种都进行了简要的重新描述，包括刚毛测量值和其他一些用于区分螨类物种的重要特征。值得注意的是，叙利亚首次报告了 Typhlodromus (Anthoseius) intercalaris Livshitz & Kuznetsov 这一物种，并根据从拉塔基亚省的 Quercus cerris L. 和 Quercus infectoria G. Olivier（椑科）树木上采集的成虫标本进行了重新描述。受检标本在肛前孔的有无方面存在差异：(1) 两侧均无；(2) 两侧均有；(3) 左侧有；(4) 右侧有。(A.) invectus Chant 的初级异名。我们试图找到主模式 T. (A.) invectus，但没有成功。然而，根据他们最初的描述，T. (A.) intercalaris 与 T. (A.) invectus 的区别在于后者胸盾上有两对刚毛，而 T. (A.) invectus 则有三对。因此，在此提供重新描述的原因是为了改进诊断，尽量减少对叙利亚标本物种地位的混淆。这一发现对于了解叙利亚植物鞘翅目昆虫的生物多样性具有重要意义。

Abstract Saraphia siamensis gen. nov. & sp. nov. (Acari: Eriophyoidea) from Mammea siamensis (Miq.) T. Anderson in Thailand is described, illustrated. We provide a geometric morphometric analysis based on different geoghraphic populations. Additionally, we report Vasates spondiasi Boczek & Chandrapatya, 1989, a new record from M. siamensis. No visible damaging symptom was observed for both eriophyoid mite species, indicating that they are vagrants on the underside of leaves.
摘要 描述了来自泰国 Mammea siamensis (Miq.) T. Anderson 的 Saraphia siamensis gen.我们提供了基于不同地理种群的几何形态分析。此外，我们还报告了 Vasates spondiasi Boczek & Chandrapatya, 1989，这是来自 M. siamensis 的新记录。没有观察到这两种麦穗螨有明显的危害症状，这表明它们是叶片背面的流浪者。
