Acanalonia conica (Say, 1830): A new alien planthopper species established in Hungary (Auchenorrhyncha: Fulgoroidea: Acanaloniidae)

Abstract

Acanalonia conica (Say, 1830), the first representative of the Nearctic planthopper family Acanaloniidae (Hemiptera: Auchenorrhyncha: Fulgoroidea), introduced to Europe, is reported for the first time from multiple locations in Hungary. Diagnosis, detailed illustration of male genitalia and notes on ecology are provided along with the distributional records.

New Data and Recent Updates on Invasive Horticultural Pest Species Acanalonia conica (Hemiptera: Auchenorrhyncha) in Romania

“…Therefore, it seems rather surprising that the species had not been recorded earlier in some countries. In many invaded countries of Western and Central Europe, GCHP has spread quickly and developed into a potential agricultural and horticultural pest [16,35,36]. In Romania, this species seems to be present into the Eastern point of Europe in Botanical Garden of Ias , i (present study).…”

“…As it is shown in Figure 7, Romania is in line with the other ten countries from Sout Europe in which GCHP has been found, in some of them being present for more than 1 years (Italy) or with a 10 (5 as mean) or more years gap between the first entrance in othe countries (Switzerland-11 years, Romania and Hungary-13 years, Slovenia-14 years, Aus tria and Serbia-16 years, France-17 years, Bulgaria and Türkiye-19 years). Therefore, seems rather surprising that the species had not been recorded earlier in some countrie In many invaded countries of Western and Central Europe, GCHP has spread quickly an developed into a potential agricultural and horticultural pest [16,35,36].

“…This last species appeared in Europe for the first time in 1979 [9], in the Veneto region (province of Treviso), and then spread rapidly throughout Italy and some other European countries. From Italy, in a short time period, GCHP was found in several European countries: Switzerland [10], Romania [11], Slovenia [12], Austria [13], France [14], Serbia [15], Hungary [16], Slovakia [17], Bulgaria [18,19], and Türkiye [19]. Some authors also considered this species as a potential pest of grapevines due to its mechanical damage by female ovipositor when inserting eggs in the wooden tissues of grapevine sprouts, thus causing mechanical damage.…”

“…Some authors also considered this species as a potential pest of grapevines due to its mechanical damage by female ovipositor when inserting eggs in the wooden tissues of grapevine sprouts, thus causing mechanical damage. Furthermore, these scars can be entry points for bacterial, viral, and fungal infections [16].…”
