Prasadiseius achlora (Prasad, 1972) is redescribed based on photomicrographs of a paratype female specimen. Chaetotaxy of the idiosoma and genua and tibia is given, including corrections to the original description. Photomicrographs of the female's insemination system are provided showing that the species of Prasadiseius probably have a "laelapid-type" but do not show the sacculus as it is apparently not chitinized.

Two-spotted spider mite, Tetranychus urticae Koch is a serious pest of different crops over the world. Different strategies are used to regulate the population of this mite. To this end, as a first step, a population growth model has been developed for describing the dynamics of T. urticae population growth. In this regard, the population abundance of T. urticae was estimated weekly from 29 June to 29 September 2016 at two bean fields, each field was planted with Goli and Akhtar cultivars, separately. During each sampling period in each field, 30 plants were randomly chosen and a leaf was selected as a sample unit from the middle of a plant, then a simple population growth model was constructed for T. urticae on two bean cultivars. The result showed that T. urticae had a distinct seasonal pattern of abundance but differed between two cultivars. A logistic growth model was developed based on relationship between the cumulative density of T. urticae and time (day) and demonstrated high prediction capability for T. urticae population on Goli (R 2 = 0.99) and Akhtar (R 2 = 0.99) cultivars. According to the logistic equation, carrying capacity was recorded 463.9 ± 9.73 (mite/leaf) and 59.67 ± 8.72 (mite/leaf) on Goli and Akhtar cultivars, respectively. Furthermore, it has been shown that the logistic growth model can be used to make population predictions. The model parameters estimated for two different cultivars, providing a new mathematical tool for ecologists to predict two-spotted spider mite outbreaks, and ultimately to develop effective two-spotted spider mite control strategies.

The aim of this study was to evaluate acaricidal activity of Melia azedarach L. ripe fruit extract against Dermanyssus gallinae (De Geer, 1778) under laboratory conditions . For this purpose, hexanic ripe fruit extract of this tree at concentrations 0.25, 0.5, 1, 3, 5 and 10% were prepared with acetone as solvent and treatment groups exposed to these concentrations using Petri dish residual film bioassay method. The positive control was carbaryl while negative control was acetone. The bioassay was repeated five times. The mortality rate of mites in treatment and control groups were assessed 24 h post exposure. All treatment groups showed significantly higher mortality compared to the negative control group (P < 0.05). All concentrations of extract showed moderate or high miticidal effects on D. gallinae as mean mortality of exposed mites to concentrations 0.25, 0.50, 1, 3, 5 and 10% were 40, 43, 60, 62, 79 and 100%, respectively. Carbaryl as a positive control caused 100% mite mortality at 1 mg/ml concentration. The LC50, 90, 99 (lethality concentrations for 50, 90 and 99%) values of this extract were calculated and were 1.78, 5.93 and 9.32%, respectively. The results of the current study revealed that the ripe fruit extract of M. azedarach was highly toxic to D. gallinae .

Varroa destructor Anderson & Truman is the most serious pest of honey bee colonies all over the world. Its specimens were assessed by morphometric and geometric morphometric methods using six morphometric traits including body length and width, length and width of the right metapodal shield, length of epigynal and the anal shield for classical morphometrics and six landmarks in ventral surface of mite's body, in seven provinces including Ardabil, Markazi, Qom, Qazvin, Alborz, North Khorasan, and Semnan. Twenty and ten individuals were used for morphometric and geometric morphometric studies, respectively. The ventral surface of each mite slide was prepared and used Digimizer and Tps package software for morphometric and geometric morphometric measurements, respectively. Data were analyzed with Past software. Furthermore, principal component analysis (PCA) was used for both two methods. In addition, Cluster analysis was used to categorize specimens of provinces. The results demonstrated significantly morphometric and geometric morphometric (or shape and size) differences among the specimens of provinces. Qazvin and Ardabil were located in one group with the PCA and Cluster analysis in the classical morphometric method and Alborz mite's dimensions showed a significant difference in morphometric measurements with other provinces. However, in the geometric morphometric method, Ardabil, Markazi, North Khorasan, and Semnan specimens were located in another group. The difference in distribution can be related to geographical factors and methods of measurement.

In addition to the female genital structures, the most Trigynaspida is diagnosed by the following combination of characters in the adults: presence of eight setae on femora IV, absence of an unpaired postanal seta, presence of the setae av4 and pv4 on tarsi IV, presence of four anterolateral setae ( al ) on tarsi II–IV, absence of salivary styli in gnathosoma and presence of hypopharyngeal styli in gnathosoma (Kethley 1977; Kim 2004). So far seven species belonging to six trigynaspid families have been reported from Iran: Asternoseiidae, Antennophoridae, Celaenopsidae, Cercomegistidae, Diplogyniidae and Schizogyniidae (Kazemi and Rajaei 2013, Kazemi and Paktinat Saeej 2013, Nemati et al. 2014). The Schizogyniidae Tragardh, 1950 a poorly known family (Ryke 1957; Kinn 1966; Karg 1977) was recorded for the first time from Palearctic region by Nemati et al. (2014). This family includes only six genera and eleven species (Ryke 1957; Kinn 1966; Trach and Seeman 2014) with the following morphological characters: usually having latigynial plates fused with ventral shield (except in Mixogynium) ; ventral shield broadest posterior to coxae IV; metasternal shields separate, fused with sternal shield or fused together into a single plate; anal plate free or fused with ventral plate; metapodal plates usually represented by large shields (except in Mixogynium), free or fused with peritremal plate (Kinn 1966; Trach and Seeman 2014). In this survey mites were separated around mouth parts of carabid beetles , Scarites sp. (Coleoptera: Carabidae) that have been deposited in Entomological Collection, Plant Protection Department, Agricultural College, Shahid Chamran University, Ahvaz in 1998. Mites were cleaned in Lacto-phenol, mounted in Hoyer’s medium and deposited in Acarological laboratory, Plant Protection Department, Agricultural College, Shahrekord University, Shahrekord (APAS). Study was done using Olympus microscope equipped with phase-contrast and digital camera. Measurements are given in micrometers (µm).
除女性生殖器结构外，大多数Trigynaspida是通过以下特征组合诊断的:股骨IV上有8根刚毛，没有未配对的后刚毛，跗猴IV上有av4和pv4刚毛，跗猴II-IV上有4根前外侧刚毛(全部)，颚骨瘤中没有唾液柱头，颚骨瘤中有下咽柱头(Kethley 1977;金2004)。迄今为止，伊朗已报道了6个三叉蛛科的7种:Asternoseiidae、Antennophoridae、Celaenopsidae、Cercomegistidae、Diplogyniidae和Schizogyniidae (Kazemi and Rajaei 2013, Kazemi and Paktinat Saeej 2013, Nemati et al. 2014)。Schizogyniidae Tragardh, 1950一个鲜为人知的家族(Ryke 1957;Kinn 1966;Nemati et al.(2014)首次在古北区记录到了Karg 1977)。这个科只包括6属11种(Ryke 1957;Kinn 1966;Trach and Seeman 2014)，具有以下形态特征:通常具有与腹侧盾融合的肋板(Mixogynium除外);腹盾最宽，在髋IV后;分离的后胸骨护盾，与胸骨护盾融合或融合在一起成为单个板;肛门板游离或与腹侧板融合;跖骨板通常由大的护盾代表(除了在Mixogynium)，游离或融合与周围板(Kinn 1966;Trach and Seeman 2014)。本文对1998年保存在阿瓦士沙希德·查姆兰大学农学院植物保护系昆虫学收藏室的小甲虫(鞘翅目:小甲虫科)口部周围的螨类进行了调查。螨用乳酸-苯酚清洗，装于Hoyer培养基，存放在Shahrekord大学农学院植物保护系螨学实验室(APAS)。利用配备相衬显微镜和数码相机的奥林巴斯显微镜进行研究。测量单位为微米(µm)。

In order to increase their inclusive fitness, animals predominantly probe their changing environment for predation cues to adopt appropriate antipredator strategies and decrease the costs of defensive behavior. Intraguild predation (IGP) occurs when a predator kills and consumes individuals of another predator which is its competitor for a shared prey. IGP is prevalent among predatory mites of the family Phytoseiidae which are used as biological control agents of agricultural pests worldwide. Phytoseiid mite mothers usually display antipredator behaviors to avoid or reduce IGP risk of their juveniles. When facing a novel IGP risk, experience may enable the mothers to display more efficient antipredator responses. We studied the effect of experience on reciprocal antipredator behaviors of an indigenous predatory phytoseiid mite, i.e., Neoseiulus barkeri Hughes, and an exotic one, i.e., Amblyseius swirskii Athias-Henriot, as biological control candidates for integrated pest management strategies in Iran. First, we determined the occurrence of IGP and mutual risk of the predators within the guild; IGP occurred reciprocally and A. swirskii was the stronger IG predator. Second, in choice situations between a patch with only shared prey and a patch with shared prey plus IGP risk cues, we scrutinized patch choice, oviposition site selection and ability to counterattack by females of each species that had either experienced the IGP risk or not. The experience did not affect patch choice and oviposition behaviors of the species whereas it elicited an increase in their predation on IG predator juveniles. We suggest that the presence of IG predator juveniles and cues may not significantly modify the distribution of the IG prey species. The reinforced counterattack behavior in experienced females showed that both species were able to tune their antipredator behavior after exposure to IG predators. Consequences of the antipredator behaviors in experienced IG prey females on distribution and possibilities of the coexistence of the study species are discussed.
