“…It is not surprising that these two species appeared to recognize each another as potential mates because they share some similar pheromones and mate-finding behaviors as well as mating periods and genitalia [10,[28][29][30][31]. However, our results showed that A. chinensis and A. malasiaca differed in terms of the male's response towards ALB females possibly due to a difference in female contact pheromone composition or other courtship signals that lead to mate recognition.…”

“…Adult females of both species emerge in late spring or early summer (depending on the climate), and newly emerged adults first search for suitable hosts for sexual maturation feeding, then mate, and oviposit in the tree trunk or branches (ALB) or in trunk and exposed roots of tress (A. chinensis and A. malasiaca) [29,30]. Mate-finding in ALB occurs as the male engages in a sequence of directed searching for the female [31]: (1) both sexes are attracted by host plants at long range via visual cues and host volatiles [1][2][3][4][31][32][33]; (2) upon landing on a tree, males are attracted by female-produced trail pheromones and volatiles from damaged twigs [34][35][36]; (3) males recognize females by visual cues and the female contact pheromone, and quickly mount and attempt to mate [37]. ALB males also produce a pheromone that primarily attracts virgin females and attraction is enhanced by plant kairomones [32,38,39].…”

“…Some of those volatile pheromone components in both species are sesquiterpenes originally obtained from the host plants and excreted by the beetles that likely play multiple roles in host location, aggregation, or mate location [32,34,36,38,41,42]. Since adult feeding is a prerequisite to pheromone production and ALB and A. chinensis (or A. malasiaca) share some same host plants [31,33], host plants could directly contribute to the amount or ratio of pheromone components [31,40]. Multiple studies have also demonstrated an overlap of chemosensory receptors between ALB and A. chinensis and a considerable semi-chemical conservation between these species [44][45][46][47].…”

Hybridization Potential of Two Invasive Asian Longhorn Beetles

The Asian longhorned beetle (ALB), Anoplophora glabripennis (Motschulsky) and citrus longhorned beetle (CLB), Anoplophora chinensis (Förster) (both Coleoptera: Cerambycidae: Lamiinae), are high-risk invasive pests that attack various healthy hardwood trees. These two species share some similar host plants and overlapping distributions in large parts of their native ranges in China and the Korean peninsula as well as similar reproductive behaviors. The original Anoplophora malasiaca (Thomson) occurs in Japan and has been synonymized as CLB (hereafter referred to JCLB). In this study, a 30-min behavioral observation of paired adults, followed by a four-week exposure to host bolts, showed that ALB could not successfully cross with CLB. Mating was observed between female CLB and male ALB but not between female ALB and male CLB, no laid eggs hatched. JCLB males successfully crossed with ALB females to produce viable eggs although the overall percentage of hatched eggs was lower than those from conspecific mating pairs. However, ALB males could not successfully cross with JCLB females. CLB and JCLB mated and produced viable hybrid offspring and the hybrid F1 offspring eggs were fertile. These results suggest an asymmetrical hybridization between ALB and JCLB, and that both CLB and JCLB might be considered as two subspecies with different hybridization potential with congeneric ALB. Given their potential impacts on ecosystems and many economically important tree hosts, invasion of these geographically isolated species (ALB and JCLB) or distant subspecies (CLB and JCLB) into the same region may facilitate potential hybridization, which could be a potential concern for the management of these two globally important invasive forest pests. Further studies are needed to determine if fertile hybrid offspring are capable of breeding continually or backcrossing with parental offspring successfully.

“…However, the effectiveness of these male pheromone-based trapping systems for monitoring Anoplophora spp. is thought to be limited (EFSA et al 2019a,b), not only because the lures used primarily attract only virgin females but it is also likely that at close range mate finding includes additional visual and chemical cues, including those coded in specific host phytochemicals (particularly sesquiterpenes) which require further research (Nehme et al 2014;Hoover et al 2014;Xu and Teale 2021).…”

Preventing invasions of Asian longhorn beetle and citrus longhorn beetle: are we on the right track?

et al. 2021

Two Asian longhorn beetles, Anoplophora glabripennis and Anoplophora chinensis are among the most serious alien invasive species attacking forest and urban trees, both in North America and Europe. Major efforts have been put into preventing further entry and establishment of the two species as well as promoting their successful eradication. Here we review these efforts, their progress and outcome, and scientific advancements in monitoring and control methods. The combined international activities and harmonizing legislative changes in detection and eradication methods have proven worthwhile, with more than 45% of eradication programmes successful in the last 12 years. Some countries were able to completely eradicate all populations and others managed to reduce the area affected. Although the costs of the eradication programmes can be very high, the benefits outweigh inaction. Attempts to eradicate A. chinensis have been more challenging in comparison with those targeting A. glabripennis. For both species, efforts are hampered by the ongoing arrival of new beetles, both from their native regions in Asia and from other invaded regions via bridgehead effects. The methods used for eradication have not changed much during the last decade, and host removal is still the method most commonly used. On the other hand, detection methods have diversified during the last decade with advances in semiochemical research and use of detection dogs. The next decade will determine if eradications continue to be successful, particularly in the case of A. chinesis, which has been targeted in some countries for containment instead of eradication.

“…In Europe, since the first record in Austria in 2001, additional infestations have been detected in other countries including France (2003), Germany (2004), Italy (2007), Belgium (2008), The Netherlands (2010), Switzerland (2011), the UK (2012), Finland (2015), and Montenegro (2015). Despite the eradication programs initiated in Europe, A. glabripennis populations are still reproducing and potentially spreading [8,9]. A. glabripennis has caused serious economic losses.…”

Anoplophora glabripennis Motschulsky, 1854 (Asian longhorned beetle) does serious damage to forests. It has a long history and wide distribution area in China and is spreading there and elsewhere. Extreme climate events, such as cold surges and droughts, have had a promotive impact on Anoplophora glabripennis occurrence, but the spatial spillover effect of extreme climate events and other environmental factors on the occurrence of this pest has not yet been clarified. Two indices, namely, Standardized Precipitation Evapotranspiration Index (SPEI) and Low Temperature Index (LTI), were used to quantify the effects of drought and low-temperature freezing damage. Based on spatial panel data modeling, this study calculated the spatial spillover effect of environmental factors on the incidence of Anoplophora glabripennis in 666 counties in China’s central plains from 2002 to 2009. The factors examined included LTI, SPEI, average wind speed, hours of sunlight, Gross Domestic Product (GDP) of regional primary industry, population density, Normalized Difference Vegetation Index (NDVI), and pest control rate. Study results indicated that the impacts of environmental factors on the incidence rate of Anoplophora glabripennis are different. Low-temperature freezing damage, drought, wind speed, and pest control rate had a driving impact on pest incidence rates. Overall, the direct effect accounts for about 85% of the total effect, while the indirect effect accounts for about 15% of the total effect.
