Abstract: Collembola, the fauna of a hidden habitat, are symbols of soil health. A survey of Collembolan fauna in different habitats in different regions of Uttar Pradesh was carried out from 2008 to 2010. Thirty-seven species were captured belonging to 27 genera from eight subfamilies of eight different families. Thirteen species are first reports from India and from Uttar Pradesh. The subfamily Entomobryinae (27.03%) was dominant whereas the subfamily Isotminae had maximum diversity.

 

Keywords: Collembola, checklist, India, Lepidocyrtus, soil health, Uttar Pradesh.

 

 

 

 

Collembola (Springtails) is one of the important fauna of phylum Arthropoda and presently considered as a separate class. They are very tiny but the most successful and abundant animal in the world. The body of Collembola is globose or tubular and divided into head, thorax and abdomen distinctly. The head bears a pair of four segmented antenna, ectognathous mouth parts within a pouch and one to several pairs of lateral ocelli, form an eye patch but these are often reduced in soil and cave dwelling species that are blind. Compound eyes are absent. They are primarily wingless fauna and abdomen is six segmented with three pregenital appendages, i.e., ventral tube or Collophore or glue peg, tenaculum or retinaculum and furcula or springing organ. Collophore is a bilobed adhesive organ found on the first abdominal segment. Lubbock (1873) introduced the scientific name for springtails considering the ventral tube or Collophore to be the most characteristic feature of the group and specifically the Collembola. The retinaculum is present on the third abdominal sternite, to hold furcula. Furcula evolved through the basal fusion of a pair of appendages on the fourth abdominal segment, is the obvious feature of Collembola. The furca is well developed as an escape mechanism to avoid predators. Rusek (2002) mentioned that the first record of Collembola was made on 2 November 1672 from Czechoslovakia whereas; the first study of Collembola from India was made by Ritter (1911) and Imms (1912)

Collembola have a very wide global distribution. They are abundant in every continent including Antarctica (Block 1984) and on newly fallen snow of the Himalaya at 7,742m altitude (Yosii 1966a). Singh & Singh (1975) and Yadav & Singh (2009) reported that they are micro soil arthropods, which together with mites, constitute an important component of soil mesofauna in almost all terrestrial ecosystems; Collembola are the second highest mesofauna after Acarina (mites). According to Maria (1989), Stork & Eggleton (1992), they are ideal for bio-indicator studies of environment due to their broad distribution and high abundance.

An initial but notable ecological study of soil arthropods including Collembola was first made by Mukharji & Singh (1970) from Uttar Pradesh, India. Literature is very scattered regarding the contribution of this group except for some of the promising work by Mukherjee (1932), Choudhuri (1963), Mitra (1966), Yosii (1966b), Prabhoo (1971), Mitra (1975), Prabhoo & Muralidharan (1980), Mitra (1993), Hazra (1995), Mandal (2010, 2013, 2014). Mandal & Hazra (2002, 2004, 2009) have presented information from different parts of India. Literature dealing with taxonomy and ecology of Collembola is immense, nevertheless the Collembola reports from Uttar Pradesh (till date) are a very small fraction, except for the work on this group by Baijal (1955) and Mitra (1973). Tyagi & Baijal (1979) provided taxonomic information of Collembola for Uttar Pradesh, India. After a long gap on this group from Uttar Pradesh, recently, Yadav & Singh (2009), Raghuraman et al. (2010), Mandal & Suman (2015), and Santeshwari et al. (2015) presented very intensive information regarding explorations from Uttar Pradesh, India.

In the present study, the author upholds recent workers classifying the Collembola as per Christiansen & Bellinger (1992). Keeping in view the above facts, the present work is aimed at finding out the diversity of Collembola for Uttar Pradesh, the largest state of northern India (Fig. 1) surrounded by Nepal and Uttarakhand to the north, Delhi and Haryana to the north-west, Rajasthan to the west, Madhya Pradesh to the south, Chhattisgarh and Jharkhand to the southeast and Bihar to the east.

 

 

Materials and Methods

The study sites located at different parts of Uttar Pradesh are given in Table 1. The investigations were carried out from January 2008 to March 2010. Collembola were collected by two methods­—through Aspirator and soil sampler. Thirty-six sites of 12 locations and samples were collected atleast two times from each site. In the field, Collembola litters were collected with the help of aspirator (Image 1), plastic tray and transparent sheet from litters of orchard and dry grasses. During collection, some amount of alcohol was used in the tray when beating the litters in order to prevent the insects from jumping. Thereafter, they were picked up with a fine brush and preserved in 70% alcohol mixed with some glycerin to avoid the loss from volatilization. Soil samples were also collected by a sampler of size 10x7.5x22.5 cm3. All the samplers’ collections were made in the mornings and collected samples carried to the laboratory in polyethylene bags, which were punctured to avoid minimum mortality of the fauna. Samples were extracted through modified Tullgren’s funnel techniques (Image 1). Soil samples were put in separate funnels fitted with mesh in the lower part of the funnels, containing 70% alcohol and few drop of glycerol. During extraction, the samples were exposed to low intensity of light initially to give low heat for a period of 12 hours and later the samples were given more intensity of light and heat for full extraction with the help of illumination timer and light intensity controller. The specimens were sorted and separated under zoom stereomicroscope in petri dish from the vials. Examinations were made under Leica MZ 16 microscope and phase contrast microscope. The temporary mounting was prepared for identification and photography. Photographs were captured by Leica DFC290 camera mounted on Leica MZ16 microscope. Subsequently, they were preserved in 70% alcohol with a few drops of glycerol. All the materials were preserved in liquid preservation in leveled vials. Standard taxonomic keys by Gisin (1960) and Christiansen & Bellinger (1992) were followed for identification. Collected specimens are preserved in the laboratory of Insect Biosystematics, Department of Entomology and Agricultural Zoology, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India.

Results

Collembola are a very diverse and abundant group of fauna. In published records by Janssens (2012) and Bellinger et al. (2016) 8,279 species of Collembola are globally described whereas, in India 301 species under 109 genera, 19 families and two suborders are described by Mandal (2010). In the present study Collembola of 37 species belonging to 27 genera from two suborders of eight subfamilies from eight different families were collected from different localities of Uttar Pradesh, India (Table 2; Images 2–6). Raghuraman et al. (2010) collected 18 genera of different species of Collembola from Varanasi, Uttar Pradesh and Santeshwari et al. (2015) recorded 26 species of 18 genera from Varanasi, Uttar Pradesh. Most species belonged to genus Lepidocyrtus Bourlet, 1839. Matiz et al. (2006) reported two species of Folsomia i.e. F. quadriculata and F. peniculata were dominant whereas, Faisal & Ahmad (2005) reported that Xenylla obscura and Isotomodes dagamae were the dominant Collembola community at all study sites. Subfamily Entomobryinae was the most diverse and dominant during investigation with 27.03% (Fig. 2) whereas, subfamily Isotominae had the highest diversity in genera, i.e., eight (Table 2). Santeshwari et al. (2015) found divergences among individuals were much higher in Hypogastrura sp. (up to 19.03%). The highest numbers of species were found in the Banaras Hindu University (BHU) campus. The common families/subfamilies were Hypogastruridae (subfamily Hypogastrurinae 10.81%), Onychiuridae (subfamily Onychiurinae, 5.41%), Isotomidae (subfamily Isotominae, 21.62%), Entom obryidae (subfamilies Entomobryinae, 27.03%, Paronellinae, 16.22%, and Tomocerinae, 2.70%), Cyphoderidae (subfamily Cyphoderinae, 5.41%), Sminthurididae (subfamily Sminthuridinae, 5.41%), Katiannidae, 2.70% and Neelidae, 2.70% were recorded during investigation. Onychurus indicus Choudhuri & Roy, 1965, Onychurus sp., Cryptopygus thermophila Axelson, 1907, Isotomurus balteatus Reuter, 1876, Folsomina onychiurina Denis, 1931, Isotomodes sp., Isotomid sp1., Pseudosinella sp., Lepidocyrtus medius Schäffer, Callyntrura sp., Yosiia sp., Salina indica (Imms, 1912) and Tomocerus sp. were found for the first time in the collection of Uttar Pradesh, India. Santeshwari et al. (2015) have also found eight species first reported from India for Uttar Pradesh. The present investigation will make a distinguished addition to the Collembola of Uttar Pradesh, India and may help to enhance the work for further research in Collembola.

Results of the present study indicate that further studies are required for documenting collembolan communities in different ecosystems of Uttar Pradesh, India. There is a great need for additional research on these environmentally important fauna of the country. The diversity of Collembola is immense and exploration is imperative.
