Hylastes ater(Curculionidae: Scolytinae) AffectingPinus radiataSeedling Establishment in New Zealand

Abstract

<jats:p>The introduced pine bark beetle<jats:italic>Hylastes ater</jats:italic>has been present in New Zealand for around 100 years. The beetle has been a minor pest on pines. Research was undertaken to control the pest in the 1950s–1970s, with a biological control agent introduced with limited success. Following a reasonably long period with minimal research attention, renewed interest in developing a better understanding of the pest status was initiated in the mid to late 1990s. Subsequently, a significant amount of research was undertaken, with a number of studies exploring the role of this pest of exotic forests in New Zealand. These studies ranged from attempting to quantify damage to seedlings, evaluate the role of the beetle in vectoring sapstain fungi, explore options for management, and evaluate the potential for chemical and biological control. From these studies, a number of findings were made that are relevant to the New Zealand exotic forest industry and shed new light onto the role of secondary bark beetles globally.</jats:p>

The effect of thinning and clear-cut on changes in the relative abundance of root-feeding beetle (Coleoptera: Curculionidae) in Pinus taeda plantations in central Alabama and Georgia

“…Further, there have been no published reports of Hylastes spp. attacking pine seedlings in the United States as reported in New Zealand with H. ater . This suggests that there should be no initial consequences on young stands if landowners were to replant pine seedlings in those harvested plots.…”

“…In the present study, clear-cut treatment had no effect on populations of H. salebrosus and H. tenuis and only a significant effect on H. porculus at some clear-cut sites. Hylastes porculus is reported to have a more northern range, 39 so its activity would 40 This suggests that there should be no initial consequences on young stands if landowners were to replant pine seedlings in those harvested plots.…”

Environmental risk assessment of carbosulfan on target and non-target beetles when used as white grub larvicide in the cork oak forest of Mamora (Morocco)

“…In its dry granule formulation, it has been recommended by the manufacturers for use against many pests. It was used, for example, against the pine bark beetle Hylaster ater (Paykul) (Scolytinae) which compromised forest regeneration of Pinus radiata D. Don in New Zealand (Reay and Walsh 2002a;Reay et al 2012), but is no longer in operational use (Reay and Walsh 2002b). Other studies have demonstrated the efficacy of carbosulfan against Hylaster ater (Lemp eri ere and Julien 1989; Mrlina et al 1994;Heritage et al 1997) and against the large pine weevil Hylobius abietis (L.) (Lemp eri ere and Julien 2003).…”

Pine Pitch Canker and Insects: Relationships and Implications for Disease Spread in Europe

“…Other common insects with high potential to spread PPC are scarabeid beetles of the genus Melolontha, which can devastate entire young plantations of coniferous species [157]. The regeneration and maturation feeding of Hylastes species (H. ater and Hylastes cunicularius (Erichson, 1836)) occurs around the root collar, killing seedlings, and sometimes destroying whole plantations [86,158]. Moreover, Hylobius spp.…”
