Summary

The eggs are laid in pods in the autumn at a depth of two to three inches in the soil most often among the roots at the base of jowar and bajra plants and of the bushes on the field bunds etc. [...] Control of grasshoppers Till recently the chief methods of control of various grasshoppers comprised of (a) destrution of the eggs by ploughing the egg-laid area or scraping of a few inches of the soil along with the egg-pods (b) poison-baiting of the hoppers and the adults and (c) trapping them in hopperdozers or tin sheets besmeared with a sticky substance such as coal-tar. [...] In the case of the Rice-grasshopper and Phadka the use of the bait is possible only when the hoppers are yet young and concetrated on the bund or in the grass land. [...] In the case of the Rice-grasshopper the condition of the field (water or mud) makes baiting inside the field unpractical and in the case of Phadka the bait spread out on the field remains untouched because the grashoppers remain always on the plants themselves. [...] However in the case of Deccan Wingless grashopper since the pest first appears in the fields themselves when the crop is almost in the germinating stage baiting is required and is practicable both in the field and around on the bunds etc.
