Climate-Induced Northerly Expansion of Siberian Silkmoth Range

Abstract: Siberian silkmoth (Dendrolimus sibiricus Tschetv.) is a dangerous pest that has affected nearly 2.5 × 10 6 ha of "dark taiga" stands (composed of Abies sibirica, Pinus sibirica and Picea obovata) within the latitude range of 52 • -59 • N. Here we describe a current silkmoth outbreak that is occurring about half degree northward of its formerly documented outbreak range. This outbreak has covered an area of about 800 thousand ha with mortality of conifer stands within an area of about 300 thousand ha. The prima… Show more

“…north. An outbreak in 2014 in cedar-fir stands of the Yenisei plain, damaged considerable forest areas north of the historical distribution area of Siberian silk moth (Kharuk et al, 2017b). Another example is the Sakhalin-fir bark beetle (Polygraphus proximus) which causes dieback of Siberian fir stands, affecting approximately 40% of forest area of the Tomsk oblast (Krivets et al, 2018;Debkov et al, 2019).…”

“…Areas with favorable temperature sums for the complete development of bivoltine populations of I. typographus (>1500 degree days (DD)) shifted northwards by an average of 450 km during the entire study period of 1960–2016 [ 26 ]. Massive 2.5 M ha outbreaks of the Siberian silk moth Dendrolimus sibiricus have shifted northward by up to 500 km in the Siberian boreal conifer forest during the last 40 years with the shift promoted by droughts and an increase in the temperature sum [ 81 , 82 ]. Higher winter temperatures and decreased summer precipitation are the main drivers of the range expansion of Mountain pine beetle, Dendroctonus ponderosae , towards the north in the USA and Canada [ 84 , 85 ].…”

“…), other pests (including invasive species), and anthropogenic activities (unsustainable silviculture, pollution, etc.) are the most important factors which contribute to the occurrence of bark beetle outbreaks [162][163][164][165]. Shoot-feeding beetles infest the crown causing growth losses, and engraver beetles, with their associated fungi, can cause significant tree mortality [166].…”

“…At the interface of the Mediterranean and Maritime zones, I. sexdentatus affected 37.9 M m 3 of P. pinaster forest after the passage of the hurricane "Klaus", with additional damages reported on P. radiata forests in the Basque Country [177]. In Russia, a large outbreak of the defoliator Dendrolimus sibiricus (Tschetverikov, 1908) (Lepidoptera: Lasiocampidae) affected 2.5 M ha of Pinus sibirica (Du Tour) and other conifers [165]. Forests affected by repeated attacks by pests and diseases, or from other abiotic-induced problems, are therefore more susceptible for F. circinatum establishment, not only by the lower vigor of the trees but also by the presence of multiple insects of various trophic guilds, which can, isolated or combined, act as vectors (sensu lato) of the PPC pathogen.…”
