The Asian longhorned beetle (ALB), Anoplophora glabripennis (Motschulsky), and citrus longhorned beetle (CLB), Anoplophora chinensis (Forster) (Coleoptera: Cerambycidae), are polyphagous xylophages native to Asia and are capable of killing healthy trees. ALB outbreaks began in China in the 1980s, following major reforestation programs that used(More)
Aphantorhaphopsis samarensis (Villeneuve), a European tachinid, has been released inNorthAmerica for classical biological control of the gypsymoth,Lymantria dispar (L.). This study examined the host range ofA. samarensis.Weused three approaches: (1) Þeld collection and rearing of potential alternate or alternative hosts at European sites where A. samarensis(More)
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.(More)
The entomopathogenic fungusEntomophaga maimaiga was introduced into aL. dispar population situated in South Bulgaria for the first time in Europe. It was found that of all larvae collected in the five experimental plots, 6.3 % contained conidia and resting spores ofE. maimaiga, 14.2 % contained parasitoids and 2.3 % were infected with nucleopolyhedrovirus(More)
A strain of Steinernemacarpocapsae obtained from overwintering codling mothscollected in Bulgaria was identified to species usingthe polymerase chain reaction. The infectivity ofthis strain towards codling moth prepupae was comparedto that of a U.S. strain at three temperatures (11, 15and 20 °C). Infectivity was low at 11 °C with 8%mortality recorded for(More)
Herbivores have been hypothesized to adapt locally to variation in plant defences and such adaptation could facilitate novel associations in the context of biological invasions. Here, we show that in the native range of the viburnum leaf beetle (VLB, Pyrrhalta viburni), two populations of geographically isolated hosts-Viburnum opulus and Viburnum tinus-have(More)
L'effet des ennemis naturels oophages deLymantria dispar (L.) est étudié dans une parcelle de la forêt de chêne-liège de Mamora, à partir d'échantillons de pontes prélevées au cours de l'été et de l'automne 1975. Les prédateurs sont les larves des coléoptèresTrogoderma versicolor (Creutzer),Anthrenus verbasci (L.) etTenebroides maroccanus Reitter; le(More)
The Asian long-horned beetle (ALB), a Cerambycidae, is an urban tree pest native to East Asia accidentally introduced to other continents via solid wood packing material. It was first detected in Europe in 2001, and since then infestations have been found in ten European countries. Using a 485-bp-long fragment of the mitochondrial barcode gene (COI), we(More)
Ips acuminatus (Gyllenhall) andTomicus piniperda (L.) were the main scolytid beetles in Scots pine,Pinus sylvestris L., outbreak areas near Orléans, France during 1978-1979.Ips acuminatus attacked thin-bark logs whileT. piniperda attacked thick-bark logs. More than 150 species of insects were associated with these scolytids. Forty-five species (31 predators(More)
Des adultes d’Ooencyrtus kuvanae (Howard) sortis d’œufs deLymantria dispar (L.) récoltés au Maroc et aux États-Unis ont été élevés séparément mais simultanément dans les mêmes conditions abiotiques. On a évalué chez ces adultes des caractéristiques bionomiques telles que la longévité, la proportion de ♀ fécondes, la fécondité réelle moyenne, la durée de la(More)
