Jumping spiders of 10 species collected from Satun, Sukhotai and Kanchanaburi Provinces of Thailand are studied. Six species are reported from the country for the first time: Evarcha bulbosa Żabka, 1985, Phintella vittata (C.L. Koch, 1846), Phintelloides versicolor (C.L. Koch, 1846 and Portia labiata (Thorell, 1887). Two of them are new to the fauna of Indo-China (Holoplatys digitatus Zhou, Irfan et Peng, 2017 and Menemerus nigli Wesołowska et Freudenschuss, 2012). Three species – M. brachygnathus (Thorell, 1887), Plexippus paykulli (Audouin, 1826) and P. setipes Karsch, 1879 – have the southernmost records of their distribution in Thailand. One species – Stenaelurillus abramovi Logunov, 2008 – has a southernmost limit of its range. Photos of living specimens for eight species, as well as drawings of the copulatory organs for H. digitatus and M. nigli are provided.

Entomological Review
Plant, spider, beetle, and ground beetle communities were studied in different agrolandscape biotopes (a wheat field, a field margin, and a forest belt) of Krasnodar Territory. In these biotopes, borders between plant communities were distinct. On the contrary, arthropod communities were not usually confined to the certain biotopes. The high degree of mobility of arthropod species resulted in a decrease in their association with the biotope. Representatives of some species (especially, beetles) were revealed in all the biotopes. In relation to season and some other factors, they frequently concentrated in different biotopes. Analysis of arthropod assemblages only within a single biotope gives us a rather impoverished knowledge of the whole population. It is necessary to study these assemblages not only within the basic biotope, but also in adjacent ones.

Entomological Review
During two years of observations of winter wheat fields, their margins and areas adjacent to forest shelterbelts, 139 species of spiders from 18 families and 92 genera were found using net-sweeping and pitfall trapping. In the fields proper, 87 species were recorded. The species number and species diversity decreased towards the central areas of the fields. High species diversity was recorded in the field edges but not in their central parts. Spiders of the families Philodromidae, Thomisidae, and Araneidae predominated in the herb-layer; the fractions of these families were greater in the fields than in their margins. Species of the family Salticidae were more numerous in the field edges and margins. Representatives of Lycosidae were the most common among epigeic spiders, their fraction reaching 90% in the field center. The dominant forms comprised 10% of the species and 80% of the number of individuals. Agrobionts common to the temperate zone of Europe predominated in the central part of the fields. They colonized the fields rapidly and distributed uniformly over the territory in spring, and then redistributed as the crops grew. The species for which the ecological conditions of the fields were favorable colonized the fields regardless of their size; other species were restricted to the field periphery.

A census of spiders has been taken in Moscow oblast and Krasnodar krai (the Kuban Plain) in fields under corn, vetch-oat mixture, and winter wheat (in the central and peripheral zones separately), as well as on their margins and in adjoinint areas of other biotopes. Spiders were collected using entomological sweeping and pitfall traps. On the whole, 286 species of 20 families and 146 genera have been found (205 species in Moscow oblast and 139 species in Krasnodar krai). The level of species diversity does not change significantly; a noticeable decrease in this parameter is observed only in the central zones of fields. In Moscow oblast, species diversity reaches a peak at field margins; in Krasnodar krai, no regular differences in this parameter between the forest strip, field margin, and the peripheral zone of a crop field has been revealed. Species diversity usually decreases toward the field center. However, changes in species diversity at a distance of more than 100 m from the margins are insignificant.

Species diversity in agroecosystems and adjacent biotopes is mainly the same. However, in central parts of fields, the value of this parameter is essentially lower. Characteristics of spider assemblages are different in the central part and edges of fields. Species-agrobionts of the families Linyphiidae, Tetragnathidae, Lycosidae, common for the temperate zone of Europe, predominated in central parts of fields. The maximum activity of most dominant species was observed in the middle of crop growing periods. The data on the spatial and temporal activity of epigeic spiders showed that they might fall into objects of pest control over the territories of agroecosystems.

The study was carried out in Moscow Area (central European part of Russia) in a winter wheat field and its grassy margins. A total of 151 spider species from 17 families and 89 genera were collected. In croplands, the families Linyphiidae, Tetragnathidae, Araneidae and Thomisidae were dominant among hortobiontous spiders, while Lycosidae, Linyphiidae and Tetragnathidae were dominant among epigeic ones. In the margins, Linyphiidae, Tetragnathidae and Araneidae prevailed among hortobiontous spiders, while Lycosidae and Linyphiidae prevailed among herpetobiontous spiders. The abiotic (soil acidity, soil moisture, organic matter content) and biotic (wheat ear height, weed abundance, plant biomass) factors studied have a different influence on the distribution of different spider groups. Their effect is diminished in the field margins. The distribution of most hortobiont web-building spiders depended on the characteristics of crop vegetation cover, as they preferred weeds. Hortobiont hunting spiders (crab spiders) were more sensitive to microclimate and preferred dry microhabitats. Herpetobiont spiders did not respond to soil characteristics in the field. The patterns of spider aggregation should be taken into account while carrying out ecological monitoring.
... Southeastern Asian countries (Myanmar, Thailand, Cambodia, Malaysia, Laos and Vietnam) belong to the Oriental Zoogeographic Region, characterized by having mainly tropical climate and consequently very rich species diversity [2]. For instance, compared to its land surface area, the Oriental Region probably has the highest number of insect species [3], and in Southeast Asia nearly twice as many spider species occur than in South Asia [4]. ...

... Concerning Plexippus paykulli, this jumping spider species has been documented in various environments such us shoreline vegetation, casuarina forests, rainforests, and human habitations (Zabka and Nentwig, 2000). While this species inhabits plants, it is also found on walls and other man-made structures (Seyfulina et al., 2020). Pupin and Brescovit (2023) suggested that it is generally associated with human dwellings and buildings. ...

... One of the main goals of ecology is to understand the distribution of species (Andrewartha, Birch 1954). The knowledge of spatial diversity patterns is important for the development of effective biodiversity conservation strategies (Gaston, 2000;Lamoreux et al., 2005;Ziesche, Roth 2008), Also, the pattern of species spatial distribution should be taken into account while carrying out ecological monitoring (Seyfulina, 2005). Arthropods, which form a major component of Earth's biodiversity, are rapidly declining in recent decades, therefore it is important to study their distribution and seek to conserve them (Gullan, Cranston 2014). ...

... The genus Pardosa Koch (1847), one of the largest and most studied genera in the family Lycosidae comprising 536 species, occurs throughout the world (World Spider Catalogue 2020). The enormous prevalence of this genus practically in all environments, including agroecosystems, has prompted a substantial investigation (Buddle et al. 2004;Schmidt et al. 2005;Clough et al. 2005;Oberg 2007;Seyfulina 2010;Dippenaar-Schoeman et al. 2013;Bizuet-Flores et al. 2015;Yang et al. 2018;Song et al. 2020). The study on the life cycle of this group has significantly progressed over the years (Bonte and Maelfait 2001;Buddle 2002;Bowden and Buddle 2012;Høye et al. 2020;Rádai 2021). ...

... Among the natural enemies observed, the most important belong to Hymenoptera, Diptera, and Fungi (Voegelé 1996) ,and they contribute to the regulation of wheat bug populations. Field margins are the main source of many natural enemies of this pest (Tshernyshev et al. 2010). The economic importance of wheat bug damage is due to crop losses and/or quality loss of wheat (Kinaci and Kinaci 2004), semolina (Ozderen et al. 2008; Köksel et al. 2009; Salis et al. 2010), or flour (Hariri et al. 2000; Sivri et al. 1999 Sivri et al. , 2004 Aja et al. 2004; Vaccino et al. 2006; Werteker and Kramreither 2008). ...
