[Laboratory study on the biology and ecology of Megasella scalaris (Diptera: Phoridae)].
TLDR
The adverse effects of larval crowding was reflected at the 100 larvae/10 g diet medium as larval and pupal periods increased and at the 200 larvae/ 10 g dietmedium larval survival declined; pupal survival decline began at the100/10g level; Fecundity was not significantly altered. Expand
Notes on the Biology of Ips pini in Central Wisconsin Jack Pine Forests
The biology of the pine engraver, Ips pini (Say) (Coleoptera: Scolytidae), was investigated employing caged and exposed jack pine logs in central Wisconsin in 1957-59. The beetle overwintered only asExpand
