Insect pest of Juniper, their parasites and predators
M. Ismail Chaudhry and Wali-ur-Rehman
ABSTRACT
Juniper forests of Baluchistan were surveyed and insect pests attacking Juniperus excelsa were studied in three localities. Semanotus semenovi Okun, Anthaxia sp., Phloeosinus jubatus and Phloeosinus sp. were recorded feeding in bark and sapwood of dead and dying trees to various extent. Infestation of these was mostly restricted to Susnamana where the trees were weakened and killed by the attack of dwarf mistletoe (Arceuthobium oxycedri M. Bieb.), a plant parasite. Trichodes sp. Healthy trees in Sasnamana, Ziarat and Chautair were found free from the attack of these borers. Trichodes sp. and Teretrius sp. were recorded as predators and Heterospilus sp. and Agathis sp. as parasites on these borers mostly in Sasnamana area. Fruit berries were heavily infested by fruit moth larvae in all the localities.
