Abstract:About 34 insect species were found infesting olive orchards in UT of J&K Among them, olive psylla, Euphyllura pakistanica; olive black scale, Saissetia olea and tinged bug, Eteoneus sp. sigilatus Drake caused serious damage. The avoidable yield losses caused by all the pest species were 33 to 53%. On the basis of various field trials conducted neem insecticidal soap (NIS @ 2.5 %) and horticultural mineral oil (HP spray oil 2% of solution) were found effective against major pests. In case of severe infestat… Show more
“…cuspidata earlier from Ramban area of Jammu and Kashmir (Schedl 1957). However, due to inaccurate taxonomic information in the relevant groups, Gupta et al (2023) recently misidentified the beetle as P. scarabaeoides besides providing other misleading taxonomic information.…”
In Jammu and Kashmir's Govindpora (Ramban) and Salamabad (Baramulla), horticultural nurseries with a majority of Olea europaea subsp. cuspidata (Wall. & G.Don) Cif. plantings were examined for possible bark beetle attacks. These olive tree plantations are infested with a variety of insect pests, but the bark beetle Hylesinus macmahoni (Stebbing, 1909) did significant harm to the olive trees that carry fruit. The beetle attacks and consumes the phloem tissues of the plant during its development, causing the afflicted trees to become weak and eventually die. At both sites, infestations of H. macmahoni were discovered. The cytochrome oxidase subunit I (COI) gene was used to validate the species' diagnosis, and its morphological characteristics were re-described. The species has a polygynous matting system (one male and two females), producing two full and a third partial generation annually in Kashmir.
