| Abstract: | In fields and worm-cages,different numbers of egg-sheets were used to maintain the same totle number of host eggs in definite space. Results indicated that the paratistical influence of Anastatus japonieus . is not distinctly connected to the number of the host eggs.It is a stochastic deed for the Anastatua japonieus to select the host eggs and to lay eggs. |
