Abstract Diet and social experience during development can have profound influences on the fitness of individuals and subsequently affect population dynamics. Understanding the factors driving population size is fundamental to ecological studies and pest management. In this study, we investigated the interplay between diet-induced plasticity, cannibalism, social interactions, and life history traits in Phytoseiulus persimilis Athias-Henriot, a natural predator of the two-spotted spider mite, Tetranychus urticae Koch. This research explored how varying prey densities and the presence of a non-feeding conspecific during P. persimilis' immature development impacts survival, cannibalism, prey consumption, developmental time, and size at maturity. Results show that survival rates are influenced by prey availability, with an increase in cannibalism observed under low prey density conditions. The presence of non-feeding conspecifics had a significant impact on P. persimilis, leading to increased prey consumption, accelerated immature development, and reduced size at maturity. These findings provide insights into the complex dynamics of predator-prey interactions and offer valuable implications for pest management strategies involving P. persimilis. The influence of diet and social interaction on additional life history traits, such as lifespan and fecundity, should be examined in future studies.

Abstract Phytoseiidae comprised over 2000 described species with different feeding habits. However, the mechanisms of food selection were virtually unknown in most phytoseiid mites. To explore the potential mechanism of odor perception, we compared the type and number of chemosensilla on the tarsi of legs and pedipalps by scanning and transmission electron microscopy in three representative predatory mites, i.e., Phytoseiulus persimilis (specialized predator of Tetranychus), Neoseiulus californicus (selective predator of tetranychid mites), and Amblyseius swirskii (generalist predator). All three species had two types of putatively olfactory sensilla, with a porous vs. grooved surface on the tip of the first pair of legs. Of these, five porous setae were found in each of the three species of predatory mites studied. However, only one grooved seta was found at the tip of the first pair of legs in P. persimilis, and two in A. swirskii and N. californicus. In addition, the pedipalp has nine grooved setae, which were hypothesized to be contact chemosensilla in each of the three species. No porous setae were found on either pedipalp or the other three pairs of legs, i.e., leg II, III and IV. Additionally, we provided a new chaetotactic notation for the tarsus of leg I by considering the type and number of setae based on our observation of the three species of Phytoseiidae studied.
摘要 植物螨科有 2000 多个已描述的物种，它们具有不同的取食习性。然而，大多数植物螨的食物选择机制几乎不为人知。为了探索气味感知的潜在机制，我们通过扫描和透射电子显微镜比较了三种具有代表性的捕食螨，即Phytoseiulus persimilis（专门捕食四膜螨）、Neoseiulus californicus（选择性捕食四膜螨）和Amblyseius swirskii（综合捕食者）腿跗蹠和足跗蹠上化学感器的类型和数量。这三个物种都有两种类型的假定嗅觉感受器，第一对腿的顶端分别有多孔和沟纹表面。其中，在所研究的三种捕食螨中，每种都发现了五个多孔刚毛。然而，在 P. persimilis 的第一对腿的顶端只发现了一个沟状刚毛，在 A. swirskii 和 N. californicus 的第一对腿的顶端发现了两个沟状刚毛。此外，在这三个物种中，每个物种的脚掌都有 9 根沟槽状刚毛，据推测这些刚毛是接触化学感器。在两只脚掌和其他三对脚（即第二、第三和第四对脚）上均未发现多孔刚毛。此外，我们还根据对所研究的三个物种的观察，考虑了刚毛的类型和数量，为Ⅰ腿的跗蹠提供了一个新的序列标记。

The present study determined the effects of different temperatures on the life history parameters and development of Typhlodromus athiasae Porath and Swirski (Acari: Phytoseiidae) for the first time. The study was conducted at 20, 25 and 30°C and the predators fed on Tetranychus urticae Koch (Acari: Tetranychidae) under laboratory conditions. Our results show that temperature significantly affected pre-adult and adult durations of T. athiasae. The adult longevity was calculated as 47.90, 22.88, 19.50 days for females, 26.11, 19.90, 20.46 days for males at 20, 25 and 30°C, respectively. The adult females of T. athiasae laid 15.80 (eggs/female), 17.20 (eggs/female) and 12.38 (eggs/female) eggs at the respective temperatures tested. The highest net reproductive rate (R0= 8.90 offspring/individual) determined at 25°C but no significant difference was found among the other temperatures. The highest intrinsic rate of increase (r= 0.12 day-1) was observed at 25°C and 30°C. Although the highest finite rate of increase (λ= 1.13 day-1) was determined at 25°C, no significant difference was observed between this temperature and 30°C. Also, the shortest mean generation time (T=14.97 day) was obtained at 30°C whereas the longest mean generation time (T=28.39 day) was observed at 20°C. Our results revealed that 25°C was more suitable for mass production even if the female and male of T. athiasae survived and reproduced at all temperatures. Consequently, our present results and the data to be obtained in greenhouse and field conditions will reveal the potential of T. athiasae as a biological control agent of T. urticae.

The samples were collected at weekly intervals between April and October from 2011 to 2014 on rosaceous plants and Quercus trees in Ankara, Turkey. Twelve spider mite species (Acari: Tetranychidae), Amphitetranychus viennensis (Zacher), Schizotetranychus ibericus Reck, Tetranychus urticae Koch, T. turkestani (Ugarov & Nikolskii), Eoteteranychus populi (Koch), E. pruni (Oudemans), E. coryli Reck, E. tiliarium (Hermann) Panonychus ulmi (Koch) (Tetranychinae), Bryobia rubrioculus (Scheuten), B. praetiosa Koch and B. sp. (Bryobiinae) were identified in Ankara. Schizotetranychus ibericus Reck, 1947 is a new record for Turkey. Tetranychus urticae and A. viennensis occurred in all the sampling localities, while S. ibericus was collected only on a Quercus sp. (Fagaceae). Tetranychus urticae Koch (Tetranychidae) was the most abundant and common species while some other species were represented by only two specimens such as Eotetranychus populi and E. tiliarum (Hermann). Apple harbored the highest number of spider mite species (9) while Prunus mahaleb and Quercus had only 2 and 1 species, respectively. The preferred hosts plants were Malus domestica (1007), Prunus domestica (749) and Prunus avium (479), while Prunus armeniaca (164), Prunus mahaleb (66) and Quercus sp. (17) were less preferred hosts. Collection data and geographical distribution of these species are provided. The checklist of the previous identified Tetranychinae species of Turkey is provided.

Pollen grains can provide important nutrients for reproduction of different predators such as phytoseiid mites. Since mass rearing of phytoseiid predatory mites may be facilitated by feeding on alternative diets, the current study evaluated the utility of plant pollen as diet for mass rearing of the predatory mite Amblyseius swirskii Athias-Henriot, which is a commercially available biocontrol agent of phytophagous mites and insects. Demographic parameters of A. swirskii fed on pollens of bird-of-paradise (Caesalpinia gilliesii), thorn apple (Datura stramonium), and maize (Zea mays) were determined over 10 continuous generations. In addition, the pollens of common hibiscus (Hibiscus syriacus), and velvetleaf (Abutilon theophrasti) were assessed, but the predatory mite was unable to reach adulthood when fed on these pollens, and most of them died in nymphal stages. This study also evaluated the preying ability of A. swirskii on the natural prey Tetranychus urticae Koch before and after 10 generations. All experiments were conducted in the laboratory under controlled conditions of 25±1°C, 60±5% RH, and a photoperiod of 16:8 (L: D) h. According to the life table parameters, the pollen grains of bird-of-paradise, followed by maize and thorn apple, were shown to be promising diets for the long-term rearing of A. swirskii. Furthermore, the study found that A. swirskii reared on bird-of-paradise pollen had a high predation capability, with a mean of 677 prey per generation after 10 generations. Overall, it is concluded that while bird-of-paradise pollen was the most suitable alternative diet for the predatory mite, both maize and thorn apple pollen grains were also found to be promising diets for A. swirskii. These diets can be used for mass rearing of this predatory mite.

Two new species, Flagellozetes (Cosmogalumna) maolanensis sp. nov. and F. (C.) longtanensis sp. nov. were discovered among the oribatid mite materials collected in China. Descriptions of two new species are presented based on specimens collected from Guizhou Maolan National Nature Reserve and Guangxi Longtan National Nature Reserve. F. (C.) maolanensis sp. nov. can be distinguishable from other species within the subgenus by the combination of the following character states: reticulate pattern in the middle part of notogaster represented by rambling neural ridges, the presence of regularly polygonal reticulation ornamentation on ventral shield, the junction of notogaster and pteromorphs forms a row of ridges, the surface of notogaster porose areas with short striae, and the surface of pteromorphs with sparsely and dispersedly protrusion. F. (C.) longtanensis sp. nov. differs from F. (C.) hrioyoshii (Nakamura & Fujikawa) by the smooth surface of prodorsum, the absence of reticulate pattern on pteromorphs, the absence of granules on notogaster porose areas, and the presence of polygonal network sculpture and granules posterior part of ventral plate. This study highlights the unexplored gaps that exist in the fauna of Chinese oribatid mites.

The subgenus Scheloribates (Topobates) (Oribatida, Scheloribatidae) is recorded in Mexico for the first time. Two new species of the subgenus—S. (T.) moskovchenkoi sp. nov. and S. (T.) paramoskovchenkoi sp. nov.—are described, based on adults collected from leaf litter from the karst pits in the secondary semi-evergreen tropical forest. Scheloribates (T.) moskovchenkoi is similar to S. (T.) tibetensis in the presence of heterotridactylous legs and long bothridial seta with elongate, lanceolate head having setiform apex, but it differs from the latter by the number of notogastral setae, the different length of notogastral setae, in having sparse small foveolae in dorsoanterior and dorsocentral parts of notogaster, the position of saccule Sa, the presence of tubercle-like process on the trochanter IV, and the absence of translamella. Scheloribates (T.) paramoskovchenkoi is similar to S.

Two new species of the subgenus—S. (T.) moskovchenkoi sp. nov. and S.

Scheloribates (T.) moskovchenkoi is similar to S. (T.) tibetensis in the presence of heterotridactylous legs and long bothridial seta with elongate, lanceolate head having setiform apex, but it differs from the latter by the number of notogastral setae, the different length of notogastral setae, in having sparse small foveolae in dorsoanterior and dorsocentral parts of notogaster, the position of saccule Sa, the presence of tubercle-like process on the trochanter IV, and the absence of translamella.
