Moth Traps

Moth Traps

Springerville, AZ—October 30, 2018 – Have you seen a small triangular box hanging from a tree when you visited a campground on the Apache-Sitgreaves National Forests (ASNFs) this summer and wondered what they were and why they were there?

Forest Health and Protection, Arizona Zone provide the moth traps that the ASNFs silviculturists (a person that studies the cultivation of trees; forestry), hang out in June and collect in October.  They are mainly used to collect information on two species of aggressive defoliating moths, the Gypsy and Douglas-fir Tussock moths.  The traps contain a female sex pheromone attracting male moths and a sticky substance traps the moths inside.

The Gypsy moth attack hardwood species, traps for them are hung in all major developed campgrounds across Alpine and Springerville ranger districts.  The Douglas-fir Tussock moth traps are hung in mixed conifer areas specifically in Douglas-fir species areas.

Knowledge is power and being aware of any upsurges before they happen gives the silviculturist time to prepare if there were to be an outbreak.  This information is extremely important to the health and protection of our forests.

Sarah Thibeault silviculturist on Springerville Ranger District for the ASNFs said, “These traps are very important to Forest Service work.  If any kind of trap is found while recreating, please leave them be! Science is happening!”
