Occurrence and Host Plant of Metcalfa Pruinosa (Say) (Hemiptera: Flatidae) in Korea

Abstract

Metcalfa pruinosa was considered to be a very harmful invasive species, due to its high species density in nature and wide range of its host plants. M. pruinosa was distributed in 28 sites among 143 sites. M. pruinosa has wide range and diverse host plants of 52 families 110 species including crop, fruits and forest trees. At present, the identified host plant of M. pruinosa are composed of 62 families and 145 species in total since their first appearance was reported. M. pruinosa was found in roadside 46.7%, followed by forests 33.3% and orchard 20%. Nymphs and adults cause damage to crop and orchard by sucking juice, outbreak of fungi through secretion of wax, and reduction of plant assimilation due to the nectar of nymphs. Also, it reduces the merchantable quality of fruits and thus causes economic damage. It is judged that M. pruinosa has been moved along major road via the traffic vehicles.

“…). This is consistent with the current serious hygiene problem and agricultural damage occurring in South Korea (Kim & Kil ). Southeastern China was currently most suitable for M .…”

“…; Strauss ; Kim et al. ; Kim and Kil ). Understanding the feeding behaviour of M. pruinosa could provide information useful in investigating the susceptibility of agricultural cops and host plant resistance, which is currently lacking.…”

“…In South Korea, M. pruinosa is capable of damaging 145 plant species in 62 families (Kim et al. ; Kim and Kil ) including trees and shrubs, ornamentals and agricultural crops such as A. palmatum Thunb. (Aceraceae), A. tataricum L. (Aceraceae) , Aesculus turbinata Blume (Hippocastanaceae) , Aralia elata (Miq.)…”

“…Mey. ; Araliaceae), Korean pear (Pyrus pyrifolia Nakai; Rosaceae), persimmon and eggplant (Solanum melongena L.; Solanaceae) has been reported (Kim et al 2011;Kim and Kil 2014). Movement via transportation of contaminated nursery trees has been suggested as one of the possible means for the rapid spread of M. pruinosa (Kim et al 2011;Hong et al 2012;Kim and Kil 2014).…”

“…In Europe, more than 330 host plant species in 78 families have been reported (Bagnoli and Lucchi 2000;Pons et al 2002;Souliotis et al 2008;Gogan et al 2010;Preda and Skolka 2011 (Kahrer et al 2009). In South Korea, M. pruinosa is capable of damaging 145 plant species in 62 families (Kim et al 2011;Kim and Kil 2014) Electrical penetration graph systems (EPG systems, http://www.epgsystems.eu/) provide a key tool to monitor, record and analyse electrical signals resulting from the interaction between a piercing-sucking insect and its host plant. The primary EPG circuit is made by connecting an insect, a plant and a device with a DC voltage source and input resistor (Tjallingii 2000).…”
