TAILIEUCHUNG - Studies on level of infestation of flat headed borer and bark eating caterpillar on Terminalia Arjuna and their management using insecticides

The Terminalia arjuna is an important deciduous tree species in India and is being utilized for both medicinal as well as sericulture purposes. The monoculture nature and continuous use of plantation for rearing of silkworm has profound negative effect on plants vigor, which attract variety of insect pests. Among them, the borer is very important pests on T. arjuna, due to their persistence attacking behavior, mainly on weak and young plants. Among the borer complex, Sphenoptera cupriventris Kerr. (Coleoptera: Buprestidae) and Indarbela quadrinotatais (Walker) (Lepidoptera: Cossidae) are important pests on T. arjuna which causes severe damage and reduce plants vigor gradually. Studies were conducted to evaluate the status of S. cupriventris and I. quadrinotatais on T. arjuna in around Bilaspur, Chhattisgarh and their management using different insecticides. The S. cupriventris infestation was significantly more in the block plantation compared to the natural plantation. Whereas, bark eating caterpillar incidence on T. arjuna was nonsignificant between block and natural plantation. | Studies on level of infestation of flat headed borer and bark eating caterpillar on Terminalia Arjuna and their management using insecticides
