Abstract:
Abstract:Taking Grapholitha molesta lure as material,with five point sampling method,the quantity of Grapholitha molesta statistic was conducted.The effect of spring ploughing, intercropping, terrain and the tree vigor on the occurrence dynamics of G.molesta were studied.The results showed that the spring ploughing was an important effect to control G.molesta .Intercropping peanuts did not have significant effect on the occurring number, but it had effect on the occurrence dynamics.Terrain affected the number of the G.molesta , but the hilltop was more effective than the hillside in orchards.The tree vigor was also important for the occurrence of G.molesta .In the experiment, the stronger pears trees were the less quantity of Grapholitha molesta .These results could guide the rational use of the agricultural measures in pear orchard.
