Students studying odonates under the microscope

Students of Don Bosco College of Agriculture, Sulcorna (DBCA) successfully participated and interacted with Parag Rangnekar, environmentalist at Mineral Goa foundation to understand and study taxomical classification of insects with special focus on dragonfly and damselfly recently.

Rangnekar provided the statistics of various organisms and stressed that majority of insects, about 80 percent are not discovered. He highlighted the importance of taxonomy (classification) which confirms the discovery of new species. He lamented that most of the insect species have gone undiscovered and continue still due to the lack of man power and interest. He appealed to the students to develop an interest in this field.

Being a native of Goa and a student of agriculture, he spoke freely in the dialect understood by the students. Having spent 10 to 15 years in the research of odonates (insects), he gave a detailed explanation on the various characteristic guidelines considered in the process of classification. He also emphasized the importance of dragonflies in the environment as pollution indicators.
A practical session was also held to give the participating students to observe and classify the insects using the guidelines given by him which the students diligently did with the help of a stereo microscope.
