Nursery pest problems on some native tree species in Kerala Province, India

چکیده
Insect pest problems in forest nurseries of selected indigenous tree species viz., Calophyllum and Pterocarpus marsupium was studied at Peechi in Kerala State. The most serious pest incidence was noticed on G. arborea (by the caterpillars of Epiplema fulvilinea); A. odoratissima (by the Psyllid Psylla oblonga) and Pterocarpus marsupium [by the psyllids Spanioneura (quadrimaculata group) and Arytaina sp.]. Moderate damage to seedlings of G. gummi-gutta by the leafhopper Busoniomimus manjunathi and by an unidentified lepidopteran leaf miner were also recorded. All the other seedling species were relatively free from major pest infestation. Also, data are presented on the nature and intensity of pest damage.
