Comparative study on the morphometric characteristics of egg-pods in various sub-families of Acrididae
Noman Shaikh and Riffat Sultana
During the present survey about 60 egg-pods were collected from different localities of Sanghar district. Collected material sorted out into 09 species. Overall, average length of egg-pod of Acridinae was noted 4.82 mm, width 0.63 mm, average length of egg pod of Hemiacridinae was noted that 5.6 mm, width 2.1 mm, and average length of egg pod of Oxyinae was noted that 5.4 mm, width 2.8 mm and laboratory observation showed that in Acrididae, the number of separate ovipositor, usually 3 and it was separated by the period of 10-20 days the number of egg in the first egg-pod reaches 120-160 in the second 80-100 and in the third 30-60. In addition to this, simplified taxonomic keys to the egg-pods of various sub-families was also presented. During the present survey from the field very small number of egg-pods were examined, it is suggested that some alternation in the key may be found necessary is due period of time. However, morphological description of egg-pods found very helpful to indicate the pest species in field.
