Pests and diseases, in particular harmful insects have caused heavy losses to the production of tropical and subtropical fruits.
A large number of species of insects affecting tropical and subtropical fruits have been reported in the world. However, in different regions of the tropics and subtropics, the number of insect species and the extent of their destructive effects are different. This paper focused on the most serious insects affecting the major fruits occurring in Vietnam, a country in the Asia-Pacific Region with natural conditions conducive to the production of many tropical and subtropical fruits. Such insects include: banana core borer weevil (Odoiporus longicollis Olivier), pineapple root-borer (Adoretus chinensis Thunber), pineapple aphid (Dismicoccus brevipes), citrus core borers, citrus. leaf weevil (Hypomeces squamosus Fabr. And Platymycterus sirversi), citrus. sucking moths (Chelidonium argentatum (Dalman), Nadezhdiella Cantoni (Hope) and Anaplophora chinensis Forester) (Othreis fullonia Clerck and others), Citras oriental fruit fly (Dacus dorsalis), citrus. leaf miner (Phyllocnistis citrella), Diaphorina citri, litchi stink bug (Tessaratoma papillosa), litchi erinose mite (Eriophes litchi), etc.
Research projects have been carried out to promote the production by applying different measures including chemical control, biological control, etc.
