Pest survey card on Dendrolimus sibiricus

Abstract

This pest survey card was prepared in the context of the EFSA mandate on plant pest surveillance (M-2017-0137), at the request of the European Commission. The purpose of the document is to assist the Member States to plan annual survey activities of quarantine organisms using a statistically sound and risk-based pest survey approach, in line with current international standards. The data requirements for such an activity include the pest distribution, its host range, its biology and risk factors, as well as available detection and identification methods. This document is part of a toolkit that consists of pestspecific documents, such as the pest survey cards, and generic documents relevant for all pests to be surveyed, including the general survey guidelines and statistical software such as RiBESS+.

New data on the distribution and abundance of Dendrolimus sibiricus (Tshetverikov, 1908) (Lepidoptera: Lasiocampidae) in the Komi Republic.

“…The habitual diet of the Siberian silkworm caterpillars consists mainly of Larix sibirica, Abies sibirica, Pinus sibirica, but in the absence of these forage plants, they are able to switch to feeding on other breeds from the Pinaceae family [16,36,37]. Since most of the Komi forests are represented by conifers there is a real threat of the formation of large foci of this pest in the republic.…”

“…The individuals were caught using adhesive traps with synthetic female sex pheromone synthesized by the FSBI «VNIIKR». The attractant was a mixture of substances Z5,E7-dodecadienal and Z5,E7-dodecadienol (1:1 by volume) [37], which were applied to a silicone plate before placing the traps. The traps had four faces with a total internal glue surface of 874 sq.…”

Pheromone-based monitoring of invasive alien insects along the border of Finland and Russia – methods and unintentionally caught species

“…In this paper, we focus on three EU-wide quarantine pests (EU 2021): the pinewood nematode, the Siberian silk moth Dendrolimus sibiricus (Chetverikov), and the foureyed fir bark beetle. The pinewood nematode (spread to trees via Monochamus beetles) causes the pine wilt disease (Futai 2013), the Siberian silk moth larvae feed on needles of a wide variety of Larix, Abies, Pinus and Picea trees (Kononov et al 2016, EFSA 2020, and the four-eyed fir bark beetle is a pest of especially Abies species in its native range, but this beetle is also potentially capable of attacking Pinus, Picea, Tsuga and Larix species (EFSA 2020a). Here, we describe the trap types and pheromones used in monitoring of these three potential IAS along the Finnish-Russian border.…”
