A model for the timing of swarming of Tomicus piniperda (Coleoptera: Scolytidae)
Tomicus piniperda is the first bark beetle to swarm in the spring in Fennoscandia. The intensity of swarming is directly related to air temperature above a certain threshold and reaches 100% asymptotically. While temperature sums above the threshold accumulate, swarming rate slows down. A non‐linear...
