AbstractScientific investigations on levels of Organochlorine Pesticide (OCP) residues in plants largely consider the edible parts (crops, vegetables, and fruit plants). Though the non-edible parts of plants are not eaten by human beings directly, these parts are consumed by livestock and other animals, thereby facilitating the flow of chemical residues through the food chain. The objective of the present investigation was to evaluate the concentration of OCP residues in non-edible plant parts to provide insights on their potential ecotoxicological impacts. Eighteen OCP residues were extracted in nine different plant species (banana Musa acuminate, brinjal Solanum melongena, Casuarina equisetifolia, Eucalyptus globulus, lotus Nelumbo nucifera, paddy Oryza sativa, sugarcane Saccharum officinarum, tapioca Manihot esculenta, tomato Lycopersicon esculentum) following QuEChERS method. The concentrations of OCP residues in plant extracts were determined using Gas Chromatography coupled with Mass Spectrometry (GC–MS). The OCP residues, namely: γ-HCH (lindane), heptachlor epoxide isomer, dieldrin, endrin, endrin aldehyde and endrin ketone were found predominantly in seven plant species. Residues of γ-HCH (lindane) were reported in different parts of plant species such as stem (581.14 ng/g in paddy and 585.82 ng/g in tapioca) and leaf (583.3 ng/g in tomato). Seven samples contained residues of heptachlor epoxide isomer (512.53 to 1173.8 ng/g). Dieldrin was found in paddy stem (489.97 ng/g), tapioca stem (490.21 ng/g) and tapioca leaf (490.32 ng/g). The detected OCPs in the present study were 10–50 times higher than the Maximum Residue Limits (MRL, 0.01–0.1 mg/Kg) as prescribed in the Codex Alimentarius of the FAO/WHO. Their elevated concentrations in the plant parts therefore pose risk of contamination to the consumers in the food chain, including human beings those are dependent on the animals as source of protein. The findings of this study are the first report on residue levels of OCPs in non-edible plant parts in the agricultural landscape of Puducherry region, India. Since, this study assumes significance for the strategic location of Oussudu Lake, an interstate lake spread over Puducherry and Tamil Nadu states, regular monitoring of OCP residues in different environmental segments in strategic locations in both the states is suggested, which will help the authorities in devising a comprehensive environmental management plan aiming at the ecosystem at large.

Study of foraging behaviour of Tricoloured Munia Lonchura malacca and its interaction in pearl millet crop fields was conducted in six villages of Tindivanam taluk, Villupuram district, Tamil Nadu from April to June 2020. A total of six flocks containing 1,640 birds of Tricoloured Munia were enumerated. The number of birds per flock varied from 60 to 800. They never split into small flocks and maintained the same flock size throughout the day. Tricoloured Munias used nine plant species for roosting. Twelve quadrats (0.3 ha) each of 5 m x 5 m size were laid in the pearl millet fields covering six villages. A total of 10,295 spikes were counted in these plots, and of these 3,785 spikes (36.7%) were found damaged by foraging munias. The maximum damage of 99.6% was observed in Thenputhur village. Along with Tricoloured Munia, five other granivorous birds, such as Baya Weaver Ploceus philippinus, Indian Silverbill Euodice malabarica, Common Babbler Turdoides caudata, Rose-ringed Parakeet Psittacula krameri, and White-rumped Munia Lonchura striata were also found foraging without any inter-specific competition. Farmers adopted various traditional bird repellent techniques such as beating utensils, throwing pebbles/soil on the crop, placing scarecrows, tying multi-coloured ribbons, and hanging bottles to chase the birds away.

Human- plant relation is tightly attached on life of human beings. From the beginning of civilization, people used many plants and their products for different purpose to adopt with their environment. The essential and valuable materials including plant species are gathered, used, saved and always remain hunger for knowledge yet now. They developed different kinds of ceremonies and rituals and include valuable materials and plants within it to protect and remains as indigenous knowledge in particular communities and groups. In this context, I want to raise the issue of material culture to search why people used plants in their rituals with reference to a plant species the Jhakro the Magars inhabitant of Baglung district, western Nepal. The research was carried out by using descriptive and exploratory research design. Observation, interview and group discussion were used in the field for primary data collection. The Magars are rich in their rituals among them death and kul pujane rituals are significant for cohesive and solidarity of the group; within these rituals a shrub plant species with special type of smell remains in central position for purity and soul. They believed that in death ritual all the polluted activities are purified and in kul pujane Jhakro acts as purity as well as help to join their ancestors with them. Unfortunately, they are unknown of the materialistic meaning of it due to lack of transferring knowledge. In etic aspect, this plant has important medicinal properties and the Magar preserved by keeping it in important rituals within their community.
