Cheiloscopy is a forensic investigation technique that deals with the identification based on lip traces. Based upon the research, it was established that the arrangement of lines on the red part of human lips is unique for each human being. The present study is an attempt to determine the pattern of lip prints and evaluate its uniqueness in a sample of Naga population and also their association with print in the four quadrants of the lip. A total of 100 (15-40) years individuals were randomly selected. With the help of brush a layer of lipstick was applied on the lips of the subject. Following the basis of Tsuchihashi’s classification the lip prints collected were studied. It was found that Type I’ pattern was predominant among the studied subjects followed by Type I and Type III pattern while Type V pattern was the least frequent Lip pattern distribution in (all four quadrants) in both males and females of Nagas. It is found that no two or more persons had similar features of lip grooves. The frequency of repetition of the lip print pattern in successive quadrant is found to be high. Lip print pattern can be used as an additional tool for personal identification.

The goal of this research is to collect and identify the specimens of Insecta that are found in and around Kiphire, Nagaland. As per the research the data on 16 specimens were collected belonging to butterflies, moths, beetles, dragonfly etc. All the specimens belong to class Insecta. The research highlights the diversity and variety of the types of insects present in the Kiphire district of Nagaland, and also the possibility of discovering many more. We strongly require intensive studies to document insects. Conservation of biodiversity involving local communities would be the best possible option in Nagaland, as the forest area are largely owned by people. The species Rosalia longicorn (Linnaeus, 1758) and Euthalia aconthea (Cramer,1777) a total of two species reported from the study area were found to be declared Vulnerable by IUCN 2.3. and WPA-II- The subspecies andamensis is legally protected in India under Schedule II of the Wildlife (Protection) Act, 1972. According to the European Environment Agency, the IUCN has not yet given this species, which includes Brithys crini (Fabricius, 1775), Myrmeleon formicarius (Linnaeus, 1767) and Drepana curvatula (Borkhausen, 1790) an official conservation threat status. Conservation of biodiversity involving local communities would be the best possible option in Nagaland, as the forest area are largely owned by people.

Acalypha indica is the important medicinal herb found commonly on the waste land and roadsides throughout India. Their various uses in traditional medicine are for curative properties against inflammation, rheumatism, respiratory disorders, fever, bacterial infection and jaundice. The mosquito control potential of common indigenous plant, Acalypha indica. Mosquito species used for toxicity bioassay are Culex quinquefasciatus, Anopheles gambiae and Armigeres subalbatus. Acalypha indica activities of the plant extracts vary according to the species. The mortality rate of 4th stage larva at 5% concentration was significantly higher than the mortality, rates at 1%, 2%, 3% and 4% concentrations of crude plant extract at 12 hours and 24 h exposure. A higher mortality rate was observed at 24 h bioassay than at 12 h. Since these plants are available very easily and cheaply, we can use these extracts in the field.

The study was carried out on impact of vibriosis by using Vibrio parahaemolyticus in Peneaus monodon Fabricius, 1798, collected from Nagapattinam. The impact was studied on heamatological and biochemical parameters. Feeds were prepared by coating probiotic strains of B. firmus and B. coagulans. Laboratory investigations were carried out concerning impact of pathogenic Vibrio parahaemolyticus of total count, differential count, Nitroblue tetrazolium activity, Prophenoloxidase activity and bacterial clearance in P. monodon. Total heamocyte was enumerated in vibriosis by induced shrimps, all results showing an increase in total haemocyte count after the time of infection. After feeding, the total heamocyte count was 1442 cells/cu·mm in control animals, in B. coagulans supplemented animals 2757 cells/cu.mm and in B. firmus was 2448 cell/cu·mm. After feed supplementation the shrimps were infected with V. parahaemolyticus and their impact on total haemocyte count was assessed in all three groups. In control, the total haemocyte count was increased with 2560 cells/cu·mm, whereas in B. coagulansis 5126 cells/cu·mm, and in B. firmusis 4697cells/cu·mm. Two-way Analysis of Variance for total haemocyte count in normal and infected haemolymph showed a significant variation. The control samples recorded the lowest, and after infection B. coagulans supplemented animals recorded maximum counts among three groups. Differential count was evaluated by studying the three types of cells. There was not much variation in the percentage of cells, but a slight decrease was observed in the hyaline cells after 24 hours of infection. The NBT activity was 1.4 (NBT activity) in control animals, 2.7 in B. coagulans and 2.4 in B. firmus supplemented animals. Maximum reduction was observed in control animals with 0.92, 1.7 in B. coagulans and 1.4 in B. firmus supplemented animals. There was an initial spurt of vibrios when cultured in selective medium TCBS in all three treatments and gradual decrease in the vibrios count during 24 hours observation.
