Insects affecting seed production of jack pine, and life tables of conelet and cone mortality in Wisconsin

Eight insect species commonly affect seed production by jack pine (Pinus banksiana Lamb.) in northern Wisconsin. Choristoneura pinus pinus Freeman, and Platylygus luridus (Reuter) attack conelets. Eucosma monitorana Heinrich, Asynapta hopkinsi (Felt), Conophthorus resinosae Hopk., and Dioryctria dis...

Zusammenfassung:	Eight insect species commonly affect seed production by jack pine (Pinus banksiana Lamb.) in northern Wisconsin. Choristoneura pinus pinus Freeman, and Platylygus luridus (Reuter) attack conelets. Eucosma monitorana Heinrich, Asynapta hopkinsi (Felt), Conophthorus resinosae Hopk., and Dioryctria disclusa Heinrich attack cones. Tetyra bipunctata (Herrich-Schaeffer), and Laspeyresia toreuta (Grote) destroy seeds. The general biology and seasonal insect attack in relation to jack pine phenology are described.
