Drought and Moisture Availability and Recent Western Spruce Budworm Outbreaks in the Western United States
Article Drought and Moisture Availability and Recent Western Spruce Budworm Outbreaks in the Western United States Bingbing Xu 1, Jeffrey A. Hicke 2,* and John T. Abatzoglou 2 1 Environmental Science Program, University of Idaho, Moscow, ID 83844, USA; [email protected] 2 Department of Geography, University of Idaho, Moscow, ID 83844, USA; [email protected] * Correspondence: [email protected]; Tel.: +01-208-885-6240 Received: 27 February 2019; Accepted: 19 April 2019; Published: 24 April 2019 Abstract: Western spruce budworm (WSBW) is a common defoliating insect that has caused extensive damage and mortality to a number of tree species across the western United States (US). Past studies have linked outbreaks of WSBW to increased moisture stress of host trees in the Northwest and decreased moisture stress in the Southwest. Our study analyzed seasonal drought stress metrics with WSBW outbreaks within Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests in the western US during 1997–2015. Superposed epoch analysis and defoliation area growth rates (representing insect population growth rates) were assessed to quantify the drought conditions associated with the initiation and continuation of outbreaks, respectively. We found that multiple years of drought occurred prior to and during outbreak initiation in the Northwest, and that outbreak initiation in the Southwest was associated with only weak drought or neutral conditions. During the outbreak continuation stage, there was a weak positive correlation between May moisture availability and defoliation area growth rates in the Southwest (R2 = 0.12), but no clear relationship was identified in the Northwest. Increased frequency of summer droughts such as these expected from climate change may increase WSBW outbreaks and promote tree dieoff. -

Does Wildfire Likelihood Increase Following Insect Outbreaks in Conifer Forests? 1,3, 1 1 1 GARRETT W
Does wildfire likelihood increase following insect outbreaks in conifer forests? 1,3, 1 1 1 GARRETT W. MEIGS, JOHN L. CAMPBELL, HAROLD S. J. ZALD, JOHN D. BAILEY, 1 1,2 DAVID C. SHAW, AND ROBERT E.

W., J. L. Campbell, H. S. J. Zald, J. D. Bailey, D. C. Shaw, and R. E. Kennedy. 2015. Does wildfire likelihood increase following insect outbreaks in conifer forests? Ecosphere 6(7):118. http://dx.doi.org/10.1890/ ES15-00037.1 Abstract. Although there is acute concern that insect-caused tree mortality increases the likelihood or severity of subsequent wildfire, previous studies have been mixed, with findings typically based on stand- scale simulations or individual events. This study investigates landscape- and regional-scale wildfire likelihood following outbreaks of the two most prevalent native insect pests in the US Pacific Northwest (PNW): mountain pine beetle (MPB; Dendroctonus ponderosae) and western spruce budworm (WSB; Choristoneura freemani). We leverage seamless census data across numerous insect and fire events to (1) summarize the interannual dynamics of insects (1970–2012) and wildfires (1984–2012) across forested ecoregions of the PNW; (2) identify potential linked disturbance interactions with an empirical wildfire likelihood index; (3) quantify this insect-fire likelihood across different insect agents, time lags, ecoregions, and fire sizes. All three disturbance agents have occurred primarily in the drier, interior conifer forests east of the Cascade Range. In general, WSB extent exceeds MPB extent, which in turn exceeds wildfire extent, and each disturbance typically affects less than 2% annually of a given ecoregion. -
Monitoring Western Spruce Budworm with Pheromone- Baited Sticky Traps to Predict Subsequent Defoliation Christine G
United States Department of Agriculture Monitoring Western Spruce Budworm With Pheromone- Baited Sticky Traps to Predict Subsequent Defoliation Christine G. Niwa and David L. Overhulser1 Abstract A detailed procedure is described for monitoring western spruce budworm with pheromone-baited sticky traps and interpreting the results to predict defoliation the following year. Information provided includes timing of the survey, how to obtain traps and baits, how many traps are needed, trap assembly, field place- ment of traps, and how to evaluate the catches. 1 Christine G. Niwa is a research entomologist (retired), U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station, Forestry Sciences Laboratory, 3200 SW Jefferson Way, Corvallis, OR 97331-8550, and David L. Overhulser is an entomologist (retired), Oregon Department of Forestry, 2600 State Street, Salem, OR 97310. Forest Pacific Northwest Research Note June D E E P R A U R T LT Service Research Station PNW-RN-571 MENT OF AGRICU 2015 RESEARCH NOTE PNW-RN-571 Introduction Because outbreaks of the western spruce budworm (Choristoneura freemani Razowski (= occidentalis Freeman)) can last a decade or more, there are many occasions when knowing the future course of stand defoliation will aid in management decisions. This is particularly true whenever an insecticide treatment is under consideration. Forest Service scientists with the U.S. Department of Agriculture (USDA) have developed a technique for predicting spruce budworm defoliation.2 This technique relates the number of moths caught in pheromone-baited traps to stand defoliation the following year. Described herein are the methods for monitoring spruce budworm and procedures for evaluating trap catch to predict future impacts from this pest. -

Inland from the coast, it is found on the western slopes and upper eastern slopes of the Cascade Range of Washington and as far south in Oregon as the Siskiyou Mountains. Farther inland, western hemlock grows on the west side of the Continental Divide from just east of Prince George, British Columbia, south through north- em Idaho and northwestern Montana.

Western Spruce Budworm
Pest Profile Photo credit: (Left) William M. Ciesla, Forest Health Management International, Bugwood.org; (Right) William M. Ciesla, Forest Health Management International, Bugwood.org Common Name: Western Spruce Budworm Scientific Name: Choristoneura freemani Order and Family: Lepidoptera, Tortricidae Size and Appearance: Length (mm) Appearance Egg The eggs are oval and light green. The adult female deposits about 150 eggs in masses of 25 to 40 eggs on the underside of the host tree needles. The eggs overlap one another like shingles. The eggs are the size of a pinhead. Larva Mature: The larvae go through six instars or stages between successive 25-32mm molts with the first instar occurring between hatching and the first molt. When the caterpillars first hatch, they are yellow-green with brown heads. The newly hatched larvae create a structure made of silk under bark or lichen and spend the winter in these structures. In the next three instars, the larvae have black heads and collars with orange or cinnamon-brown bodies. The fifth instar larvae have reddish-brown heads that are marked with black triangles and collars. The body is a pale olive-brown marked with small-whitish spots. The mature caterpillars have tan or light chestnut-brown heads and collars. The body is olive or reddish- brown with large ivory-colored areas. Adult Length: 13 mm Both sexes of the adults are similar in appearance; however, the Wingspan: female can be larger. The wings can be variable in color and can 22-28 mm range from a gray or orange brown with the wings possibly being banded or streaked. -
