Evaluation For Mango Varietal Resistance To 3 Species Of Insect Pests On Tender Shoot Among 76 Varieties/germplasm

Chlumetia transversa Walker, Erosomyia mangixola Shi and Deporaus marginatus Pascore are the three of the most important pests attacking mango in South China. The studies on evaluation for host resistance to the 3 pests attacking tender shoots on 76 varieties/germplasm were respectively carried out in the field during 2002-2004. Under the pressure of the natural pest population, the information concerning the varietal responses to the damage by the 3 pests and the population dynamis on 76 entries tested in the experiment. The data collected were analyzed by the methods of Duncan's multiple difference analysis and cluster analysis to evaluate the resistant level of the entries tested . The results from these studies are summarized as follows.1.
