What is the pupation time for White Pine Weevil in relation to its adult emergence?

The pupation time for the White Pine Weevil is typically around 10-15 days before the adult weevils emerge. Understanding this timeframe is crucial for effective pest management and control strategies, as it relates directly to the life cycle of the insect. The weevil undergoes its transformation from larva to pupa, and this period is critical for developing the adult characteristics necessary for reproduction and dispersal.

Knowing the accurate pupation time helps in timing pesticide applications, as treating during or shortly after this phase can effectively target the emerging adults before they begin to cause damage to host plants. It’s important to monitor environmental conditions during this time as well, as pupation may be influenced by factors such as temperature and humidity, potentially affecting the precise timing of adult emergence.
