Abstract: Based on the measurement of the amount of egg deposition of Ceracris kiangsu and observations on its landing locations,traces of eggs left on the ground after predation by birds and the damage symptoms of the branches on the lower part of the culm's tip,it's easy to guickly and accurately distinguish its concentrated egg deposition localities. Based on the damage degree of the bamboo leaves,a table for checking egg densities was established,which can be used for forecasting the occurrence and damage degree of this insect in the following year.
