15-25% tree mortality

5-15% tree mortality

Mortality potential without intervention

2011 | SPB Rapidly Expands

SPB Impact | Quick tree loss

• Trees may show signs within days of attack

• Pines die as quickly as 3-4 weeks after initial attack

Gerald J. Lenhard, Louisiana State University, Bugwood.org

SPB Impact | Canopy Loss

• Changes forest type

• Decreases wildlife habitat

• Reduces recreation and aesthetic quality

• Increases stream temperatures and sediment buildup

SPB Impact | Hazard Trees

•Dead pines are highly susceptible to rot fungi

•Branches and tops readily break

•Poses a danger to people and property

SPB Impact | Wildfire Risk

•Dead trees are standing fuel

•Falling needles increase ladder fuels

•Forest floor dries faster without canopy cover

Ronald Billings, Texas Forest Service, Bugwood.org

SPB Impact | Blue Stain Fungi

• Beetles transmit fungus

• Fungus establishes in days

• Wood’s value decreases

Erich Vallery, USDA Forest Service, Bugwood.org

SPB Lifecycle

• 4-6 weeks to mature

• Multiple generations per year in the same area

• Larval stage feeds on tree’s inner bark

• Galleries girdle tree

SPB Look-alikes

Engraver Ips Beetles• I, Y, or H shaped galleries • Found in the top half of the tree• Rear of beetle has spines and a “scooped” appearance

Black Turpentine Beetle• Rear of the beetle is rounded• Found in the lowest 18 inches

Southern Pine Beetle• Rear of the beetle is rounded• Found throughout the tree

SPB Spot Growth

SPB Triangle for Spot Growth

Ronald F. Billings, Texas Forest Service

Expanding SPB Infestation

• Generally expands in one direction• May fly and start new hotspot in adjacent forest

Effects of SPB Spot Disruption


Cut-and-Leave Suppression

• Disorients beetles and disrupts population growth• Found successful in prior suppression efforts

across the US and Central America

Cut-and-Salvage Suppression

• Decreases fire hazard• Disrupts all life stages• Preferred method

Successful Suppression | Winslow WMA

NJFS | SPB Monitoring

• Monitors SPB and clerid populations

• 18 Traps

• Baited with pheromones and turpentine

• Contents sent to US Forest Service


NJFS | Managing DEP Lands

• Survey - aerial flights

• Map data and determine ownership

• Verify state lands spots on ground

• Mark area for cutting

• Cut within a week

• Monitor after treatment via air and ground

NJFS | Managing Other Lands

• NJFS communicates with Municipal liaison

• Municipality notifies private landowners

• Municipal grants available for management and restoration

Landowners | Protect Individual Trees

• Safeguard high-value trees

• Treat trees with spray or injection

• Protect a tree for 3 months to 2 years depending on treatment

• Contact a licensed pesticide applicator

*Only effective prior to an attackEmamectin benzoate
