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:: Litter, one of the forest habitats includes the layer of dead plant materials present on soil surface, comprising the surface litter (L-layer), the partially decomposing layer beneath it (F-layer) and the humus layer (H-layer). It plays a major role in the transfer of energy and nutrients in the forest ecosystem; litter fall data is often used to predict the productivity of ecosystem. The natural forest litter, surface and associated ground with its floral diversity and specialized micro niches support a variety of macro and micro arthropods including spiders through variations in moisture, cover materials, litter depth and structure. A strong correlation between species diversity of ground dwelling spiders and litter habitat is thought to exist because habitat affects spiders through prey availability, temperature fluctuation, moisture content and harborage. Ecological importance of spiders is undeniable as they are abundant predators of other forest litter arthropods. Globally people are laying emphasis on the studies of litter and ground dwelling spiders while India is yet to jump into. It is believed that the monograph is the first comprehensive study on the forest litter and ground dwelling spiders of the reserve forests of Dooars, West Bengal, India.

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:: Spiders have established themselves as a model group in biochemical (silk and venom proteins), behavioural (sexual and web building behaviours) and ecological (foraging, prey-predator interaction and IPM) research. They are also utilized as ecological indicators in many terrestrial communities. Appreciating the bioresource value of spiders, present discourse is second in the series on the spiders of Gorumara National Park, Chapramari WildLife Sanctuary (Dist. Jalpaiguri) and Mahananda WildLife Sanctuary (Dist. Darjeeling), West Bengal, India. The study area falls within the eastern Himalaya, one of the global hotspots. It is worthwhile to mention that despite sincere efforts Indian spiders of the protected areas remained unexplored until the editors initiated studying the group since 1993. The monograph embodies taxonomic account and distribution of the species recorded from different ranges of these reserve forests.

Opis:: A field trial is conducted to study the seasonal incidence of five pests namely Brinjal shoot & fruit borer [Leucinodes orbonalis Guenee], Hadda beetle [Henosepilachna vigintioctopunctata (Fabricius)], Mealy bug [Centrococcus insolitus (Green)], Aphid [Aphis gossypii (Glover) and White fly Bemisia tabaci (Gennadius) on brinjal in relation to weather parameters at agricultural farm of RKMVERI campus, Narendrapur during kharif & rabi crop seasons (2019-20). The brinjal crops receive pests load from 9 to 15 week plant age and 10 to 17 week plant age during kharif and rabi crop season respectively. The all five pests attain maximum peak sequentially sharing various microhabitats for feeding on host plants. Among the five pests recorded shoot & fruit borer appears as the major pest enjoying the crop to its optimum throughout the season till harvest and seems to cause heavy damage in brinjal production. Mealy bugs attack the brinjal leaves only in the kharif crop whereas white flies are encountered in the field during rabi crop season only. In kharif season during the crop growing period, borer caterpillar incidence % is significant and positively correlated with avg. temperature (°C). For rabi season due to lack of complete field data on the incidence pattern of pest species correlation coefficient values are not generated. Data generated so far prompts to assume that the pest species are now with strong genetic stability irrespective of climate change and/or improvised agronomic practices.

Opis:: The present study unfolds the diversity of ants of Bibhutibhushan Wildlife Sanctuary, North 24 Parganas, West Bengal, India. A total of 22 species under 13 genera distributed over 5 subfamilies could be recorded. These include three newly recorded species namely Leisiota frauenfeldi (Mayr) (Formicinae), Crematogaster (Acrocoelia) hodgsoni Forel (Myrmicinae) and Brachyponera nigrita Emery (Ponerinae) from the state and nearly 90.5% of the reported species are new for the district (marked*). Analysis of their zoogeographical distribution reveals that the fauna apart from being Oriental also includes some Palaearctic (72.73%), Australian (13.63%) and Ethiopian (4.54%) elements. The dominant functional group is constituted by the Subordinate Camponotini (36.37%) followed by Generalized Myrmicinae (22.73%), Tropical Climate Specialist (13.63%), Specialist Predator (9.09%), Opportunist (9.09%) and Dominant Dolichorinae (9.09%). Ants are mostly prevalent during Monsoon (81.82%), followed by Postmonsoon (68.18%) and Premonsoon (50.00%). Two species namely Camponotus (Tanaemyrmex) compressus (Fabricius) and Oecophylla smaragdina (Fabricius) are recorded throughout the year. Ranking sequence of the most abundant species in descending order is: Camponotus (Tanaemyrmex) compressus (15.01%) = Oecophylla smaragdina (15.01%) > Crematogaster (Acrocoelia) hodgsoni (12.91%). Camponotus (Tanaemyrmex) compressus and Oecophylla smaragdina are the most dominant species. Data also reveals that both core and buffer zones conjointly offer a better combination of habitat requirement, as 12 species are common in both the zones. Highest no. of species are recorded from leaf litter and ground combined together (22 species) and 6 species are arboreal in nature. Shannon’s Diversity Index (α diversity) and Simpson’s Diversity Index both are higher in buffer zone. This reflects the habitat exploitation efficiency of the encountered species. As per Jaccard Index (β diversity) the similarity value of both the zones is only 0.55.

Opis:: Ant-aphid mutualism is considered as a beneficial, reciprocal and myrmecophilous association. Ants farm aphids, harvesting honeydew or flesh, in return protect the aphids from their natural foe i.e. predators and parasites and perhaps for other benefits like acceleration of aphid’s growth and reproductive rate and in the establishment of aphid colony. And finally aphid could get a pest status. Some of the aphid species are better adapted to profit from the presence of ants than others and benefits are more marked in small populations than in large ones (Saha & Raychaudhuri, 1998). Therefore, it seems essential to know about the interacting ants, their relationship with aphids in any agroecosystem for a better management strategy. The present paper attempts to document the aphids and aphidocolous ants against different host plants. Our investigation during August, 2017 – July, 2018 results a total of 40 aphid infested host plants along with 7 species of aphidocolous ants. Out of 10 aphid species recorded Aphis gossypii (Glover) is tended by more no. of ant species (5) followed by Rhopalosiphum maidis (Fitch) by four (4) species of ants. Aphidocolous ants demand serious attention as their attendance promotes aphids to reach pest status as well as ant populations need a check so that they may take care of fewer aphid individuals.

Opis:: The present study is on the spider fauna of Barasat and Basirhat of North 24 Parganas, West Bengal, India. A total of 23 species belonging to 20 genera and 11 families are sampled during the period August 2016 to July 2017. These include the newly recorded species, Anepsion maritatum (O.P. Cambridge) from the state. The dominant guild is constituted by the Orb web weavers (30.43%). Analysis of their zoogeographical distribution reveals that the fauna apart from being Oriental also includes some Australian (23%), Palaearctic (21.73%) and Ethiopian, Nearctic and Neotropical (each 17.39%) elements. Spiders are mostly prevalent during Postmonsoon (82.60%), followed by Premonsoon (60.86%) and Monsoon (47.82%) which is in conformity with the incidence of the insect species. Two species namely Eriovixia excelsa (Simon) and Leucauge decorata (Blackwall) are recorded throughout the period of survey. All the diversity indices are higher in case of Basirhat as compared to Barasat. An overall negative impact of urbanization on spider diversity, distribution and abundance is evidenced from the present study. Ranking sequence of the most abundant species (six) in descending order are: Leucauge decorata (25.68%) > Eriovixia excelsa (19.13%) > Pholcus phalangioides (11.48%) > Plexippus paykullii (8.74%) > Anepsion maritatum (7.10%) > Cyrtophora cicatrosa (6.56%). Sex ratio (♀ : ♂) is about 12 : 1. Availability of food/season and/or cannibalism may be the factors for female dominated society.

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.

Opis:: Our study on ant diversity of Bibhutibhusan Wildlife Sanctuary, N-24 Parganas, West Bengal during the period, August 2017-July 2018, unfolded wonderful Batesian and Wasmannian mimicry (chemical mimicry) between model ants Tetraponera rufonigra (Jerdon) and its sibling T. allaborans (Walker), Oceophylla smaragdina (Fabricius) and salticid spiders of the genus Myrmarachne Macleay. Siblings of Myrmarachne encountered are M. plataleoides O. P. Cambridge, M. maratha Tikader and M. orientales Tikader. It is supposed that chemical or Wasmannian mimicry enables species with ant-like pheromones to live in close contact with ants. The members of spider Myrmarachne that resemble the aggresive weaver ant Oceophylla smaragdina, with which they live in close contact, also show chemical resemblance. Further, by mimicking the ants they gain protection from predators. Since weaver ants have a painful bite and also taste bad, this strategy appears to be successful. Though these spiders mimic the weaver ants very well, they are known to stay away from them. They weave a thin web on the leaves, hide under their webbing and ambush their prey. Present communication attempts to discuss the morphological and structural similarities between the mimics and their models. It is worthwhile to mention that such a mimicry is reported for the first time from this part of the country.

The forest appears to be a scaled down West Bengal as the area represents 1/2, 1/3rd and 1/5th of the elaterid taxa (subfamilies/genera/species). Out of 34 species 13 are considered new to science, while 11 to West Bengal and 9 to Buxa Tiger Reserve. The fauna shows high degree of endemism. These beetles are mainly found during premonsoon (88.88%).The fauna is largely Oriental. Heteroderes sericeus Candeze is the most abundant species (45%), followed by Cardiophorus ferruginosus sp. nov. (15%). Seventeen species are singletons while 15 species are represented by only two to seven individuals. Find of more number of males suggests more of their response to sex pheromones and dispersal ability.

Total no. of species and alate individuals are found to vary between sites and trap colour. Yellow is found to be the most preferred colour (no. of alatae: 1080). Among the seven species trapped, Aphis gossypii alatae dominate over rest of the species. All the seven species are supposed to be invasive ones to crops. From late September alate aphids initiate migration from subtropical regions to plains and continue till March. It is felt that early sowing of the winter crop/flowering plants may avoid pest aphid incidence.

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).
