Summary<\/u><\/h2>\n

In our country Meliaceae<\/em> is one of the main families in forest. Up to now 19 genera and about 90 species have been identified. Some species of high economic value of sub-family Swietenioideae have been and are being used for forest planting or forest enrichment such as Chukrasia tabularis <\/em>A.juss, Toona sureni<\/em> (Blume) Merr., Toona sinensis<\/em> (A. Juss.) Roem… One of the greatest handicaps in planting and developing the above-mentioned species is pest insects of which shoot borers cause serious losses. Results of the survey on the composition of shoot borer species on some tree species of the Meliaceae and level of damage caused by them will help the forest development and forest protection planning staff to identify main shoot borer species and select species of high economic value in this family less susceptible to the shoot borer Hypsipyla robusta., <\/em>ensuring their successful planting and protection.<\/p>\n","protected":false},"excerpt":{"rendered":"
