Abstract/Description: | Studies on the biology of the surface grasshopper, C. trachypterus were carried out under laboratory conditions for two successive rabi seasons (Nov. 2005 – March 2006 and Nov. 2006 – March 2007) at the Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur. The females laid eggs in moist soil at a depth of 3-6 cm. Egg pods were hard, elongated and cylindrical with a slight bend at the middle. The average eggs laid per female were 65.500 ± 4.365. The average incubation period was 22.975 ± 1.015 days under laboratory conditions. The total nymphal period ranged from 43.50 to 53.50 (48.513 ± 0.496) days; with the first, second, third, fourth, fifth and sixth instars taking an average of 9.900 ± 0.238, 8.613 ± 0.302, 8.300 ± 0.173, 7.186 ± 0.191, 6.625 ± 0.146 and 7.913 ± 0.232 days, respectively. The pre-oviposition, oviposition and post-oviposition periods were 18.000 ± 0.793, 36.150 ± 2.075 and 12.250 ± 1.039 days, respectively. Adult longevity of male and female was observed as 54.350 ± 3.005 and 66.400 ± 3.210 days, respectively under laboratory conditions. The average linear biometrical data of egg pods, eggs, six nymphal instars and the adults (male and female) have also been presented. |
