“…Two species which form physical supports of predilection to excavate nest cavities in Levaillant's woodpecker (Badis and Hamdi 2022). They offer optimal and safe conditions for the implementation of cavities such as the low ammability and consistency of cedar woods, as well as its tolerance to various water and climatic stress (Valette 1990 In woodpeckers, the dimensions, and shapes of the entrances to their nest cavities are adapted according to body size (Kerpez and Smith 1990; Kosinski and Ksit 2007; Wan et al 2008). In Levaillant's Woodpecker in the Aures Mountains, the surveys carried out as part of this study show that the entrances are mostly round (94.2%).…”

Levaillant’s Woodpecker Picus vaillantii is a primary cavity nester endemic to the forests of northern Africa, including the cedar forest in Aures Mountains. This species, as like all woodpeckers, is important for the integrity of ecosystems, especially since it provides nesting cavities and contributes to the availability of habitats for several secondary cavity nesters that cannot dig their own nests. To characterize for the first time the Levaillant’s Woodpecker’s nest cavities and to test the effect of local climatic conditions on the sizes and orientations of these cavities in Aures cedar forests of north-eastern Algeria surveys were carried out in 2018 and 2019 breeding seasons using the point count method to search for the nests of the Levaillant’s Woodpecker. Based on measures realized on a total of 52 available nest cavities, results reveal entrances with a dominance of round shapes (94.2%) compared to oval shapes. The mean height and width values of the cavity entrances were 7.26 ± 1.51 cm and 7.11 ± 1.44 cm. The depth of the internal chamber and its width were estimated at 35.42 ± 7.82 cm and 17.95 ± 4.01 cm respectively. Unlike the average values of the volumes of the internal chamber, those relating to the entrance area and orientation vary significantly according to altitude and climatic conditions. Indeed, when climbing towards the summits, the cavities widen and turn to the west-southwest. This behavior of the Levaillant’s woodpecker seems to help it to benefit from maximum sunshine at high altitudes and to avoid predators and competitors more abundant at medium low altitudes.

“…At present, there seems to have been no studies showing the adaptive advantages of particular nest orientations, but it is believed that they occur. Landler et al (2014) included data from 12 studies on Great Spotted Woodpeckers and all but three of these studies found random orientation, the exceptions being studies in Great Britain (Tracy 1938), China (Wan et al 2008) andPoland (Hebda 2009). In the present study of White-backed Woodpecker cavities across Hungary, orientation was non-random with a general alignment and southerly orientation of entrances prevailing.…”

The objective of this study was to document characteristics of cavities used for breeding by White-backed Woodpeckers Dendrocopos leucotos in Hungary. Twenty-five nest cavities were examined over a period of ten years (2011–2020). Five different tree species were used. The cavities were excavated at a mean height of 4.6 m and 2.2 m standard deviation and ranged from 2 to 8 m. All cavities found were in the main trunks of trees with trunk diameters ranging between 35–55 cm with a mean of 41.6 cm and 5.6 cm standard deviation. A southerly orientation of cavity entrances prevailed with a mean direction of 189±74 clockwise from north (median 180° IQR = 113°). The results suggest that cavity entrance orientation was non-random.

“…Mixed tree planting and the conservation of deadwood have been shown to encourage woodpeckers to move into forested areas . The physical characteristics of nest holes have also been identified in order to produce suitable artificial nest holes or nest boxes for woodpeckers, and have also been successfully used to encourage woodpecker predation of Anoplophora …”

“…The biological control prospects for predators are more promising, as both woodpecker species that predate on A. glabripennis are native in Europe and would only require measures to encourage their establishment in an area of infestation, such as artificial nest boxes and changes in management of woodland to allow more deadwood and more diversity of tree species …”

Prospects for the use of biological control agents againstAnoplophorain Europe

This review summarises the literature on the biological control of Anoplophora spp. (Coleoptera: Cerambycidae) and discusses its potential for use in Europe. Entomopathogenic fungi: Beauveria brongniartii Petch (Hypocreales: Cordycipitaceae) has already been developed into a commercial product in Japan, and fungal infection results in high mortality rates. Parasitic nematodes: Steinernema feltiae Filipjev (Rhabditida: Steinernematidae) and Steinernema carpocapsae Weiser have potential for use as biopesticides as an alternative to chemical treatments. Parasitoids: a parasitoid of Anoplophora chinensis Forster, Aprostocetus anoplophorae Delvare (Hymenoptera: Eulophidae), was discovered in Italy in 2002 and has been shown to be capable of parasitising up to 72% of A. chinensis eggs; some native European parasitoid species (e.g. Spathius erythrocephalus) also have potential to be used as biological control agents. Predators: two woodpecker (Piciformis: Picidae) species that are native to Europe, Dendrocopos major Beicki and Picus canus Gmelin, have been shown to be effective at controlling Anoplophora glabripennis Motschulsky in Chinese forests. The removal and destruction of infested and potentially infested trees is the main eradication strategy for Anoplophora spp. in Europe, but biological control agents could be used in the future to complement other management strategies, especially in locations where eradication is no longer possible.
