Tree Fruit Insect Pest Biofixes

A biofix is a biological marking point (usually a date).  In this case, biofix refers to the date at which an insect first emerges from pupation in spring.  We determine biofix by hanging species-specific pheromone traps in the host tree.  Male insects are attracted to the scent of the pheromone, and will become trapped on the sticky liner.  We check the traps daily to determine the date when the traps start catching moths.  To learn more about determining a biofix for a certain insect, check out our tree fruit insect fact sheets.
