The main objective of the study is to review the practices of Zootherapy among the ethnic groups of the northeastern part of India and to prepare an inventory of all the information. The data were collected from 11 published papers on the practices of zootherapy among different ethnic groups from the region. All the papers were published in the years 2002-2016. A total of 181 animals species are used by 19 ethnic groups from the region. Mammals are the most widely used animal groups followed by Arthropods, Aves, Pisces, Reptiles, Annelids, Amphibian and Molluscs. The number of the animal species are-77 species of Mammals (42.5%) followed by 65 species of Arthropods (35.9%), 24 species of Aves (13.25%), 22 species of Pisces (12.15%), 18 species of Reptiles (9.94%), 6 species of Annelids (3.31%), 5 species of Amphibians (2.76%) and 4 species of Molluscs (2.21%). The most commonly treated ailments are-Tuberculosis, Malaria, Diabetes, Asthma, Arthritis, Rheumatic pain, Jaundice, Anaemia, Paralysis, Pertussis, etc. This review on the zoo therapy practices among the ethnic groups of the region will summarise all the information in one place which will be helpful for the scientists and researchers working in the field of ethnomedicine to study and develop new potential drugs.
Odontotermes parvidens is a commonly found important pest species of termite that primarily feed on a range of cellulosic sources. In termites, communication among the nestmates is the basis of all their daily activities and the sensory structures present on the sensory appendages play a crucial role in different social behaviors perceiving and processing various signals of the nestmates and external environments. So, it is essential to understand in detail their sensory structures in order to understand the sensory system of the species O. parvidens. Thus, we have studied the antenna which is one of the primary sensory appendages of both soldier and worker individuals of the species to elucidate various antennal sensory structures and their distribution using scanning electron microscopy. Based on the morphological features of various sensilla, we observed seven types of sensilla as sensilla chaetica (subtypes I, II, III, and IV), sensilla trichodea (subtypes I and II), sensilla trichodea curvata (subtypes I and II), sensilla basiconica, sensilla capitula, Böhm bristles, and sensilla campaniformia (subtypes I and II) along with numerous glandular pores on the antenna of soldier and worker castes. We have also discussed the putative functions of all the sensilla observed based on their external morphology and distributional characteristics on the antenna of soldier and worker castes of the species O. parvidens. Furthermore, the abundance of sensillar types on the antenna of both the castes has also been discussed.
Stenachroia elongella is an important pest of maize in Meghalaya, India. To understand the roles of sensory organs in the biological behaviors of this insect, we determined the structure and distribution of sensilla found on the antenna of both male and female S. elongella by scanning electron microscope. The antenna of both sexes is a filiform type, and the overall length of the female antenna is significantly longer than the male antenna. In both sexes, seven types and two subtypes of antennal sensilla are identified; sensilla trichodea, sensilla chaetica, sensilla styloconica, sensilla coeloconica, sensilla auricillica (I, II), sensilla squamiformia and Böhm sensilla. No sexual dimorphism on the specific occurrence of sensilla is observed. Probable functions are discussed based on their external morphology. These results would be helpful for further studies on TEM investigations, electrophysiological recordings, and behavioral studies.
Research Highlights
Seven types and two subtypes of antennal sensilla were observed in both male and female Stenachroia elongella.
Morphology and distribution of the antennal sensilla were discussed.
Sexual dimorphism was observed on the overall length of the antenna where the female antenna is longer than the male antenna. No sexual dimorphism was observed on specific occurrences of antennal sensilla.
Aplosonyx chalybaeus is a major insect pest of the plant Colocasia which is commonly found in the North-Eastern region of India. The antenna of A. chalybaeus is filiform, composed of a scape, a pedicel, and a flagellum with nine flagellomeres. The type, structure, and distribution of sensilla, on the antennae of the adult A. chalybaeus (Coleoptera: Chrysomelidae), were examined by scanning electron microscopy. Eight different types of sensilla were observed on the antennae using scanning electron microscopy, that is, sensilla trichodea, sensilla chaetica, sensilla basiconica, multiporous grooved pegs, sensilla auricillica, sensilla styloconica, glandular plates, and Böhm sensilla based on their external morphology. Distribution of all the antennal sensilla observed was discussed on the antenna. In addition, we discussed the putative functions of all the sensilla observed based on their external morphological and distributional characteristics on the antenna of the species.
Research Highlights• External morphology and distribution of various antennal sensilla in male and female of Aplosonyx chalybaeus were described.• Eight types with 17 subtypes of antennal sensilla were observed.• Distinct sexual dimorphism was observed in occurrence and distribution of various sensilla.
Eurydema dominulus (Scopoli), a phytophagous insect and a pest of many plants. The external morphology of the sensilla on the wings were observed using scanning electron microscope. Based on their morphological structure, different five types of sensilla were distinguished: sensilla trichoidea, sensilla chaetica, sensilla basiconica, sensilla campaniformia and sensilla ampullacea. These sensilla can be related to have mechanosensory, chemosensory and proprioceptive functions. The possible roles of these sensilla are also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
