Study on ants, spiders on Varattar river banks
Chengannur: A study about ants and spiders on the banks of Varattar river and Adipampa has started. The insects are being observed as part of the study of biodiversity initiated by the Department of Zoology in Chengannur Christian College. The ants and spiders are collected from bushes and trees. The study will be staged by regularly recording of the diversity of the insects.
Ant researcher Manoj Vembayam led the data collection process. He taught the students the methods of collecting the ants from the surface of soil using a special type of filter and collecting them on a cloth by shaking trees. The study will last for two months. In order to analyze the ants that live beneath the soil, they are collected in a bottle in which meat is enclosed in a particular method. Spiders also are collected as part of the study.
Ants and spiders are ecological indicators. The use of chemical pesticides, inefficient waste management, pollution and similar factors cause damage to the environment. The impact of this damage is first visible in the insects like ants, spiders, worms, butterflies and dragonflies which live close to nature. These insects are found very rarely in places where pollution is rather high, said Dr. R. Abhilash, faculty of zoology department in Chengannur Christian College.
