Opis:
The longhorn beetles or round headed borers are in their greatest abundance in the tropics. These borers are included within 13 subfamilies that are delineated by their morphological characters, the most primitive being the Prioninae while the rather advanced are Cerambycinae and Lamiinae. Hanks (1999) in his review on the works done during the past 90 years did discuss the informations available only for 81 species. He (op. cit) indicated that the average publication rate is less than one species per year. This paucity of information is reflective of the rarity with which researchers record sufficient detail of the cerambycids. Again, on the other hand, the forests of Dooars in particular are not only rich in animal life forms but also for the wealth of trees. These in turn make an economic return for which silviculture is a regular practice. The quality of such trees (logs) are often assessed by the buyers before bidding. It is needless to mention that the deterioration in the quality is mainly because of the woodborers that usually burrow in the tissues of the woody plants in conditions ranging from alive to moribund to dead and decomposing. However, some species feed within the stems of living herbaceous plants. All such habitat deteriorations other than being natural events are often accentuated because of the plantation practices. Adaptation to such highly variable host plant quality has certainly resulted in a diverse spectrum of cerambycids with tremendous variation in their behaviour and ecology. A sustained management plan therefore demands a thorough and intensive study on these wood borers attacking the trees/timbers/shade trees of tea plantations. The study should involve biodiversity assessment followed by biology. Knowledge on the diversity spectrum along with their associated hosts would essentially form the basic. The work in future days may be extended to biology. Therefore, study on the taxonomic diversity of the cerambycid of Dooars appears imperative in order to develop a sustained management plan against the quality deterioration of the trees/timbers.

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:
The native host plants bearing wildflowers with overlapping blooming periods provide resource for the butterflies, the significant pollinators next to bees. Few of the behavioural features of these diurnal pollinators are co adapted to the phenology as well as fragrance chemistry or floral morphologies of their host plants establishing an ecological specialization state often maintained by stabilizing selection. Such specialization may lead to the considerable variation among reproductive success rates of the host plants. Thus, species specific pollinating attributes over the seasonal continuum of the pollinators towards their common host plants may provide idea about their pollinating potentiality. Lycaenids, with 443 Indian species, are commonly termed as ‘blues’. Two representative species, the Quaker and Lime Blue are selected on the basis of their moderate to high abundance level in the study area. Few of their prominent ecological and ethological features concerned to their host plant visiting patterns are reported. The present study is important for highlighting the role of native pollinators to maintain the regional to landscape level floral diversity. The significance of conservation of such global bioindicators also cannot be neglected.

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:
Nymphalids, the largest lepidopteran family, is represented by altogether 19 species (37% of the total species abundance) from the present study site Taki, West Bengal, India, with multiple habitat profiles exposed to different anthropogenic interventions. Nymphalidae is reported to be with highest occurrence of mimicry, a naturally selected survival tool for lepidopterans. A nymphalid set, including a model [Plain Tiger: Danaus chrysippus (Linnaeus, 1758)] and a mimic component [Danaid Eggfly ♀: Hypolimnus misippus (Linnaeus, 1764)] is selected for studying the specific ecological and functional correlation among them in their natural habitat. Their comparative seasonal and habitat wise distribution shows co-existence, the unpalatable model species outnumbering the mimic, the vulnerable target, corresponding to the Batesian mimicry. The wing morphology pattern is significantly shared, though the larval and adult host plants are exclusive and species specific. The year long field observation indicates the existence of considerable degree of similarity with respect to the ecobiological details, like flight pattern, mudpuddling, resting, basking and alternative resource utilisation activities. Species specific unique foraging attributes is observed. Being potential pollinators, they play key role to maintain the wild floral diversity at landscape level. The study bears conservation value towards these nature’s artwork, acting as the biotope indicator.

Opis:
Understanding the significance of butterflies in an ecosystem as an environmental healthy indicator and pollination of flowering plants is crucial to achieve sustainability and conservation of floral diversity. The aim of the study is to investigate the butterfly species diversity and abundance and compare the relationship between physical factors and butterfly species at Taki, North 24 Parganas. Survey of six habitats, each containing specific ecological and socio economic profile was conducted. Diversity varies among habitats. Seasonal parameters also play vital roles as the distribution factors for local butterflies. A checklist is made comprising a total of 51 butterfly species belonging to 5 families. Sixty eight species of plants belonging to 28 families served as the larval host plants and 36 species of plants belonging to 20 families served as the nectar plants for butterflies. Maximum number of individuals found at SC (Surrounding College, College Ground, College Hostel Ground) site. The highest species richness and abundance are reported during the post monsoon. The abundance pattern is correlated to the foliage and nutritional support provided by the host plants, both at developmental and at adult stages. Nymphalidae is the most dominant family with 37% of the total number of species.

Opis:
Coloration and mimicry are the naturally selected survival tools for lepidopterans, both in larval and adult life either playing the protective or aggressive or advertising or cryptic or camouflaging mechanisms. Besides being nature’s priceless artwork, butterflies are one of the most beneficial terrestrial insects, playing a major role as pollinators and an essential component of commercial agriculture, horticulture, wild plant and animal diversity. They also play role as bioindicators. The natural distribution of butterfly populations in any local habitat is primarily defined by the distribution of their nectar plants and larval host plants as there exist species specific relationships among the host and nectar plants and the dependant butterflies. Also there exist specific ecological and functional correlation among the mimetic forms (the models and mimics and the individual members of a mimicry-complex or Mullerian ring) found in any particular habitat. The present study is focussed on observation, documentation and analysis of mimetic butterflies commonly found at Taki, North 24 Parganas; availability and prominence of mimicking sets, their intra- and interfamily relationships, reporting about their larval host plants and nectar plants. The study also has an importance from conservation approach.

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.

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.

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.
