November 2015 Monochamus spp.: insect vectors of Bursaphelenchus xylophilus Longhorned beetles of the genus Monochamus spp. are vectors of the pinewood nematode Bursaphelenchus xylophilus (PWN) that may cause the death of pine trees. In the EPPO region, PWN has established in continental Portugal, where the main vector is Monochamus galloprovincialis. Beetles of Monochamus emerging from PWN-infested trees/wood are able to carry PWN and transmit it to non-infested trees during maturation feeding. Theoretically, hitchhiking beetles could present a risk of introducing PWN to new areas/countries but information on hitchhiking Monochamus is missing. Information is missing on the vectors of the genus Monochamus, in particular data on flight distances and total dispersal over the lifetime of the adult beetle but also about the best methods for monitoring. In case of introduction of pinewood nematode in a new country, this information is indispensable for risk assessment and emergency measures. The project will gather and process available information for best prediction of damage risk of Monochamus spp. Five countries and seven institutions participate in this project: Portugal, Slovenia, Belgium, The Nertherlands and Denmark. These countries are different in status with respect to both the presence of Monochamus spp. and of pinewood nematode. The project’s main results include: . Best monitoring strategies for Monochamus spp. Mapping of PWN and occurrence of native Monochamus species across Europe . Phenology studies of Monochamus spp., prevalence of nematodes in longhorned beetles and dispersal studies of M. galloprovincialis . Identification of factors that lead to variations in expression of disease due to Bursaphelencus spp. in different regions of Europe . Forest management practices and their impact on Monochamus spp. Molecular detection methods for Monochamus spp. Project ID: Monochamus spp.: insect vectors of Bursaphelenchus xylophilus (MONOCHAMUS) .

Pine Wilt Rapid Wilting and Death of Pine
Pine Wilt Rapid wilting and death of pine Pathogen—The pine wood nematode, Bursaphelenchus xylophilus, causes pine wilt disease. Nematodes are “roundworms” in the phylum Nematoda, which has over 80,000 described species. This disease can be a problem wher- ever non-native pines are planted but is most common in Kansas, Nebraska, and South Dakota. Vectors—The pine sawyer beetles, Monochamus spp., transmit the nematode. Please see the Roundheaded Wood Borers (Longhorned Beetles) entry in this guide for more information. Hosts—Scots, Austrian, and other non-native pines are often killed by this disease. Eastern white pine, a native pine, is also affected and may be killed by pine wilt disease. The nematode commonly infects other native pines and some native conifer species. However, most native species are resistant to the disease (e.g., native conifers may be infected and express little or no disease Figure 1. Symptoms of pine wilt disease symptoms). on Austrian pine branch. Photo: North Cen- tral Research Station Archive, USDA Forest Signs and Symptoms—As with many wilts, signs are microscopic. The Service, Bugwood.org. pine wood nematode is relatively large compared with other nema- todes, but it cannot be seen with a hand-lens in infected wood. Laboratory tests are required to confirm its presence. Pine wilt disease causes rapid wilting and death on non-native pines. Symptoms are often first expressed in early summer but can occur throughout the growing season. Symptoms may first appear on one or a few branches but often develop quickly throughout the crown, and trees may die only 1 or 2 months after symptoms appear.

Red Ring Disease of Coconut Palms Is Caused by the Red Ring Nematode (Bursaphelenchus Cocophilus), Though This Nematode May Also Be Known As the Coconut Palm Nematode
1 Red ring disease of coconut palms is caused by the red ring nematode (Bursaphelenchus cocophilus), though this nematode may also be known as the coconut palm nematode. This disease was first described on coconut palms in 1905 in Trinidad and the association between the disease and the nematode was reported in 1919. The vector of the nematode is the South American palm weevil (Rhynchophorus palmarum), both adults and larvae. The nematode parasitizes the weevil which then transmits the nematode as it moves from tree to tree. Though the weevil may visit many different tree species, the nematode only infects members of the Palmae family. The nematode and South American palm weevil have not yet been observed in Florida. 2 Information Sources: Brammer, A.S. and Crow, W.T. 2001.

Although a secondary pest in its native North America, PWN has devastated conifer forests in invaded regions of eastern Asia, and more recently of southwestern Europe, incurring huge management costs to attempt eradication which remains unsuccessful. So far, only one native European species, M. galloprovincialis, has been proven to have developed a novel association with the invasive PWN.

ABSTRACT: Red ring disease (RRD) is of particular importance in many African oil palms- and coconut-producing regions in Central and South America and the Caribbean. Its causal agent, the nematode Bursaphelenchus cocophilus (Cobb) Baujard, causes extensive damage to tissues in the plant trunk that typically leads to plant death within months. Nearly 100 years after its first report RRD remains understudied largely because the nematode cannot be cultured in vivo or in vitro, what hinders sustained research efforts on basic and applied aspects of the pathosystem. To overcome this problem we attempted in vivo culturing in coconut seedlings, paying attention to aspects that had been overlooked in previous trials. We also attempted in vitro culturing on several fungi endophytic to healthy and RRD-affected coconut trees. In the two in vivo assays performed we were able to recover hundreds of nematodes from the seedlings up to 60 days after inoculation, but the nematodes seemed unable to sustain parasitism in most seedlings.

Abstract: Pine wilt disease (PWD) is caused by the pine wood nematode (PWN; Bursaphelenchus xylophilus) and causes severe environmental damage to global pine forest ecosystems. The current strategies used to control PWN are mainly chemical treatments. However, the continuous use of these reagents could result in the development of pesticide-resistant nematodes. Therefore, the present study was undertaken to ﬁnd potential alternatives to the currently used PWN control agents abamectin and emamectin. Benzyloxyalkanols (BzOROH; R = C2–C9) were synthesized and the nematicidal activity of the synthetic compounds was investigated. Enzymatic inhibitory assays (acetylcholinesterase (AChE) and glutathione S-transferase (GST)) were performed with BzOC8OH and BzOC9OH to understand their mode of action. The benzyloxyalkanols showed higher Citation: Kim, J.; Lee, S.J.; Park, J.O.; nematicidal activity than did benzyl alcohol. Among the tested BzOROHs, BzC8OH and BzC9OH Yoon, K.A.

Asian Longhorned Beetle in Colorado - Identification of Insects and Damage of Similar Appearance
Colorado Exotic Insect Detection and Identification Fact Sheet Series Asian Longhorned Beetle in Colorado - Identification of Insects and Damage of Similar Appearance Matt Camper and Whitney Cranshaw Figure 1. Asian longhorned beetle larvae. Photo Figure 2. Female Asian longhorned beetle. Photo courtesy of Michael Bohne courtesy of Michael Bohne The Asian longhorned beetle (ALB), Anoplophora glabripennis, is a wood boring beetle of Asian origin that was first detected in Brooklyn in 1996. Two years later a separate infestation was found in the Chicago suburbs. The Asian longhorned beetle has the potential to be very damaging to certain types of hardwood trees, causing tree decline and even death. Many native trees are susceptible to this insect and there are concerns that it could seriously affect natural forest systems as well as shade trees. Intensive efforts to eradicate this insect have been instituted where it was detected. This effort appears to have been very successful in the Chicago infestation and Asian longhorned beetle was officially declared eradicated in 2007. However, infestations in the New York City area have spread more widely so that detections of the insect have occurred in all city boroughs, parts of Long Island, and three New Jersey counties. Areas known to be infested remain fairly small and sustained eradication efforts continue to attempt elimination of the insect in New York and New Jersey. In addition, quarantine efforts prevent movement of wood materials that could be potentially infested from outside the area of known infestation. Introduction of Asian longhorned beetle into Colorado most likely would occur via hardwood packing materials (Figure 3) originating from China-shipped goods.

The production of the pine tree secondary metabolite gradually increases in response to a B. xylophilus infestation, via a stress reaction mechanism(s). α-pinene is needed to combat the early stages of B. xylophilus infection and colonization, and to counter its pathogenesis. Therefore, research is needed to characterize the underlying molecular response(s) of B. xylophilus to resist α-pinene. We examined the effects of different concentrations of α-pinene on the mortality and reproduction rate of B. xylophilus in vitro.
