Japanese flower thrips (Thrips setosus Moulton, 1928) (Thysanoptera: Thripidae) was found in Croatia in May 2016 on potted hydrangea plants (Hydrangea spp.) originating from domestic production. It was found in the open, in a nursery in Turanj (N 43°58′18.5″E 15°25′1.5″). This is the first record...

Invasive wood borers vectoring pathogenic fungi have nearly exterminated several North American tree species, and it is unclear whether landscape dominant trees, such as pines, will face similar threats in the future. This paper explores the economic impacts of a hypothetical arrival of a...

Papers are presented focusing on biological control agents and how they are regulated across the EPPO region, how their use can be facilitated and how they may contribute to slowing the spread of invasive pests and mitigating the damage they cause. Three papers deal with Dryocosmus kuriphilus, a...

Cryptoblabes gnidiella is an opportunistic species native to the Mediterranean region. This species has been reported from several dozen host plants, including many cultivated plants, especially fruit (e.g. grapes, lemons or pomegranates). It is considered a serious pest together with accompanying...

Pitch canker, caused by the pathogen Fusarium circinatum, is a serious disease of pines, Pinus species. It is a threat to natural and planted pine forests, and to date it has invaded countries across five continents. Pine-feeding insects can play a key role in the epidemiology of the disease, as...

We present records for six new stink bug species reported for Puerto Rico. These include two predatory species: Apateticus lineolatus (Herrich Schäffer) and Tylospilus acutissimus (Stal) (Asopinae); and four phytophagous species: Berecynthus hastator (F.), Chlorocoris tau Spinola, and Acrosternum (...

The glassy-winged sharpshooter, Homalodisca vitripennis, is an insect that transmits the economically important plant pathogen Xylella fastidiosa. Homalodisca vitripennis has been widely studied in North America and the characteristics that make the insect highly successful in new geographic areas...

The invasive alien species, Metcalfa pruinosa (Say), has been spreading in Korea since it was first recorded at Gimhae in Gyeongnam province in 2005. This species has caused damage to major forest trees and several agricultural crops both by direct plant sap feeding and by indirectly vectoring...

This paper presents the results of several trials conducted in 2009-14 in Italy to test different control strategies against the grapevine mealybug (Planococcus ficus), an introduced species in Trentino, which can cause direct damage (limiting production) and indirect (virus transmission) on the...

Several subfamilies of ants have medical consequences because of the transmission of bacteria by specific ants and because of stings with the injection of venom that may produce life-threatening human reactions. These reactions will be discussed and related to specific ant species. Other adverse...
