COMPARATIVE STUDY ON THE MORPHOMETRY AND KINEMATICS IN DIFFERENT SPECIES OF GRASSHOPPERS

Dr. Padmanabha B

Abstract :

Objective:is to study the relation between morphometry and kinematics in different species of grasshoppers.

Materials and methods: Six species of grasshoppers collected in the Mysuru city during 2016–2017. The morphometry carried out by digital caliper and kinematics estimated by measuring tape and stop watch.

Results and discussion:Among three species of grasshopper nymphs, Phlaeoba panteliwas fastest with highest velocity but least body length and hind leg length.Gastrimargus africanus was with highest body weight, body length and hind leg length but with least distance covered per hop. Oxya nitidulawas with lowest body weight, speed, velocity but highest distance covered per jump.Among four species of adult grasshoppers, Phlaeoba panteli was fastest with highest length of hind leg, speed and velocity. This indicated that the length of hind leg might have increased the speed, velocity and the distance per hop. Aiolopus thalassinus was with highest body weight but least speed, velocity and distance per hop. This result suggested that the body weight may decrease the speed, velocity and hop distance in grasshoppers.

Conclusion: In grasshoppers decrease in the body weight, increase in the body length and hind leg length may increase the speed, velocity and hop distance.To ing more precise correlation between morphometry and kinematics further study should be carried out in different species of grasshoppers
