Passiflora an annual climber famous for its spectacular flower compared with passion of Christ occurs with distinctive 500 species genetic diversity across the globe. Passiflora is cultivated as a botanical decorative purpose and well known as a fruit crop. P. foetida stinking passion flower leaves are trifoliate with enamours traditional and pharmacological potential drug value. Its speciality lies in its unique opening pattern of flowering. A healthy and sturdy growth of plants is the main cause of attraction for varied diseases, viruses, pest, caterpillar and mites that attack for feeding purpose. P. foetida is no exception to pest attack with diverse, unique and special features. In this communication, we aimed to evidence of leaf eating caterpillar Acraea violae or tawny coaster who feeds on leaves of P. foetida indirectly making maximum damage to the plant. This caterpillar attacks leaves of P. foetida in the experimental domesticated plants that were grown for test's purpose in Vidarbha region of India. These pests attacks and destroys leaves in very small period of time and chews them to purge completely to make leaves porous. It was observed that this pest attacked leaves, stem, tendrils and flowers. However, roots were not observed for manifestation. Similar observation was found in Nagpur, Amravati, Jalgaon district of India. A complete life cycle of Acraea violae beginning from egg to be fully matures butterfly stage has been described. Here we also discussed a unique opening and closing pattern of a flower of P. foetida.
The population densities of four major zooplankton groups (Rotifera, Cladocera, Copepoda and Ostracoda) present in Sahebbandh showed significant differences (p<0.01) between different months within a year. Significant differences were also observed (p<0.01) for ten physicochemical parameters (water temperature, water transparency, pH, dissolved oxygen content, free carbon dioxide content, ammonia content, chloride concentration, sulphate concentration, nitrate concentration and phosphate concentration) with respect to the months of a year in Sahebbandh. Correlation between zooplankton population densities and physicochemical parameters has been studied calculating the Pearson correlation coefficients. Rotifera population density exhibited significant positive correlations with Ammonia content, nitrate concentration and sulphate concentration in lake water. Cladocera population density showed significant positive correlation with water temperature. Copepoda population density expressed significant negative correlation with water transparency and phosphate concentration and significant positive correlation with sulphate concentration. Ostracoda population density has expressed significant positive correlation with water transparency and significant negative correlation with free carbon dioxide content in the water of SahebBandh. Multiple regression analysis has been employed to further study the impact of changing physicochemical parameters on the population densities of four major zooplankton groups present in the water of Sahebbandh.
Avifauna is one of the best indicators of environmental changes. The population of birds in any kind of ecosystem shows the environmental quality of the area, pollution level, security and availability of food and habitat. The human-bird association is since ancient times and is an intimate one. Birds have always served humans with incalculable services such as pollinators, biocontrollers, scavengers, predators, seed dispersals and so on. India is a home for about 1710 bird species. The estimated bird species on the earth is around 8600. At present the rapid developmental activities are posing threats to a number of bird species directly or indirectly. This study was taken up to assess the occurrence and distribution of birds in Tikamgarh district of Madhya Pradesh. Tikamgarh district is known to abode the breeding colonies of Critically Endangered vulture species in Orchha. It also includes some birds that are considered Near Threatened and Endangered worldwide. Tikamgarh district supports about 170 bird species belonging to 46 families. This is a preliminary and basic effort to bring out the incredible bird fauna of Tikamgarh district which has suffered severe droughts and deforestation. It has zero percent of very dense forest, 1.9% of moderately dense forest and 4.1% of open forest according to Forest Survey of India.
