Opis:: As a potential predator the importance of spiders, especially dwelling in rice land, needs to be properly addressed. Till date the information gathered in this field isinsufficient. Due to various reasons, members of the family Araneidae Clerck, 1757, exhibit striking variability particularly in Gangetic delta. After sampling for two years, it is found that, Neoscona theisi (Walckenaer, 1841) is the most dominant group in the fields of South 24 Parganas, West Bengal, India, amongst araneids and their average sex ratio increases during kharif session due to multiple environmental factors including reproductive strategies.

Opis:: Spiders inhabiting rice land ecosystem demand serious consideration primarily due their predatory efficiency. In India, their role as a potential bio-control agent is yet to be evaluated. The coastal ecosystem in the Gangetic Delta at the southern part of West Bengal, India, exhibits a wide variety of predatory spider population because of climatic fluctuation, soil quality and several other factors. Orb-weaving spiders appear to be of special importance as they trap more than what they actually consume. The present study is aimed at unfolding the taxonomic diversity of Tetragnatha Latreille, 1804 (family Tetragnathidae, Menge, 1866) which is probably the mostly predominant group amongst orb-weavers found in rice fields of South 24 Parganas, West Bengal, India. Of the seven tetragnathid species recorded from the study area, three, T. chauliodus (Thorell), T. boydi O. P. - Cambridge, and T. josephi Okuma are found to be new from the country. The referred species are therefore described and illustrated. Further a key to the species occurring in the area has also been provided.

Opis:: This paper is a study of diversity and seasonal abundance of soil inhabiting arthropod fauna and their interrelationships with the edaphic factors like temperature, moisture and pH in flower garden, vegetable garden and uncultivated area dominated by weeds in Ramakrishna Mission Ashrama Campus, Narendrapur, South - 24 Parganas, West Bengal. The soil arthropods were collected with the help of Berlese-Tullgren funnels. Altogether, 591 arthropods belonging to 7 different groups viz., Acarina, Arachnida, Collembola, Coleoptera, Diptera, Hymenoptera and Psocoptera were extracted from each of the three plots every month during the entire survey period (August 2018 – July 2019). Microarthropod abundance was found to be greater in uncultivated areas (266 individuals) as compared to that of the flower and vegetable gardens where different agronomic practices are adopted and traditional means of garden nurturing viz. tilling, raking, weeding, etc. are followed. Of the total population in all three plots, mites were the most dominant group (37.06%), followed by ants (25.21%) & springtail (19.29%) populations. Soil arthropods populations are greater in the monsoon season (227 individuals), followed by premonsoon (188 individuals) & postmonsoon (176 individuals).

Opis:: A survey of spiders associated with the rice agroecosystem in Ramakrishna Mission Ashrama Campus, Narendrapur, South 24, Parganas, India results a total of 17 species under 16 genera distributed over 7 spider families in kharif crop season during August 2019 – November 2019. Of these, two species Rhene decorata Tikader and Thomisus sikkimensis Tikader are recognised as endemic to India. Runcinia insecta (L. Koch) is recorded for the first time from West Bengal and Camaricus formosus Thorell, Cyclosa spirifera Simon and Neoscona theisi (Walckenaer) recorded first time from rice field of West Bengal. Total number of spiders per sample is maximum in the maturity stage of paddy when pests attain their peak. Spiders are collected from diverse habitats within the paddy field, viz. crop canopy, border weeds and in the flood water. Among spiders family Salticidae is the most dominant group. Analysis of their zoogeographical distribution reveals that the fauna apart from being Oriental also includes some Ethiopian (17.65%), Australian, Neotropical and Palaearctic (each 11.76%) and Nearctic (5.88%) elements. The dominant guild is constituted by the Ambushers (7.44%) followed by Ground Runners (6.37%) and Orb Web Weavers (3.19%). Ranking sequence of most abundant four species are [in descending order]: Oxyopes shweta (Tikader) (34.72%) > Plexippus paykullii (Audouin) (13.89%) > Camaricus formosus (Thorell) (12.50%) > Rhene decorata Tikader (9.72%). Sex ratio (♀ : ♂) is around 11 : 1. Availability of food/season and/or cannibalism may be the factors for female dominated society. This work aims to generate data-base on the diversity spectrum of spiders in the rice agroecosystem along the growth period of the rice plants and to propose definite management plan for limiting pesticidal load.
