First record of the onion psyllid Bactericera tremblayi (Wagner, 1961) in France (Insecta: Hemiptera: Sternorrhyncha: Psylloidea), new symptoms on leek crops and reassessment of the B. nigricornis‐group distribution

Abstract

The triozid Bactericera tremblayi, or onion psyllid, is recorded for the first time from France, and is associated for the first time with important damage on leek crops in several regions of the country. We compare the morphology of this species with the two other species of the B. nigricornis‐group, in order to avoid misidentifications, and illustrate the different stages of B. tremblayi. The published distribution of the three species is summarised and updated based on collection data, and the presence of B. tremblayi and B. trigonica in Jordan and Spain (Canary Islands) respectively, is also recorded for the first time.

Search for potential vectors of ‘Candidatus Liberibacter solanacearum’: population dynamics in host crops

“…They have polyphagous habits and show overlapping areas of distribution. These species were formally reported in Bosnia-Herzegovina, France, Greece, Iran, Italy, Serbia, Switzerland and Turkey (Ouvrard & Burckhardt, 2012). Here, we report the presence of B. tremblayi and B. nigricornis in Spain in addition to B. trigonica, which was already reported by AlfaroFernández et al (2012b) and is widely distributed in the Mediterranean region (Haapalainen, 2014).…”

“…The identification was based on morphological characteristics using classification keys (Ribaut 1936(Ribaut , 1952Ramírez, 1955Ramírez, , 1956Ramírez, , 1959Shaposhnikov & Davletshina, 1967;Hodkinson, 1981;Hermoso de Mendoza, 1982;Ossiannilsson, 1992;Ouvrard & Burckhardt, 2012). Some specimens were mounted on slides following the method of Hodkinson & White (1979) and photographed.…”

Rapid Communication. Tamarixia monesus (Walker) (Hym.: Eulophidae) parasitoid of Bactericera tremblayi (Wagner, 1961) (Hemiptera: Triozidae) in Iran

“…It has been found in Italy (Wagner 1961;Tremblay 1965;Conci and Tamanini 1988), Turkey (Klimaszewski and Lodos 1979), Switzerland (Burckhardt 1983), Greece (Burckhardt 1988), Bosnia-Herzegovina (Đuric and Hrnčic 2010), France (Ouvrard and Burckhardt 2012), Jordan (Ouvrard and Burckhardt 2012), Serbia (Jerinić--Prodanović 2006), Spain (Teresani et al 2015) and Iran (Burckhardt and Lauterer 1993;Kazemi and Jafarloo 2008). Bactericera tremblayi attacks diff erent families of host plants especially: Amaryllidaceae, Amaranthaceae, Apiaceae, Asteraceae, Brassicaceae, Caryophyllaceae and Solanaceae (Klimaszewski and Lodos 1979;Burckhardt 1983;Conci and Tamanini 1988;Jerinić-Prodanović 2006;Kazemi and Jafarloo 2008).…”

Vector mediated transmission of Candidatus Liberibacter solanacearum and epidemiological consequences

“…Several factors threaten the yield and thus the economic benefits associated with these crops of which pests and diseases are one of the most important factors associated with crop losses. Recently, a group of hemipteran insects known as psyllids have become important pests of carrot, celery, potato leek and onion crops in Europe (Munyaneza et al, 2010a;Alfaro-Fernández et al, 2012a,b;Ouvrard and Burckhardt, 2012). This group of insects cause direct damage to the plants and also transmit pathogens.…”

“…Among the transmissible pathogens, the most economically important is the phloem-restricted bacterium Candidatus Liberibacter solanacearum (Lso). Currently, psyllids as well as Lso are well established in different European countries and are spreading to new areas (Munyaneza et al, 2010a;Alfaro-Fernández et al, 2012a;Ouvrard and Burckhardt, 2012;Loiseau et al, 2014;Munyaneza et al, 2015). Therefore, information about how psyllids transmits Lso is important to understanding the epidemiology of this pathogen and to establish effective management practices.…”
