Pentatomid stink bugs (Hemiptera: Pentatomidae) include several species that occur in pear orchards where they cause feeding damage with their piercing-sucking mouthparts, resulting in deformed fruits. In the Belgian fruit growing area they used to be secondary pests, but over the last decade they...

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...

The western flower thrips (Frankliniella occidentalis) is an invasive thrips pest of tomatoes in the southeastern United States. This species causes crop loss to farmers by injuring fruits and vectoring Tomato spotted wilt virus. Previous attempts to control this species using calendar applications ...

Diseases of unknown aetiology remain difficult or impossible to diagnose. Illumina next generation sequencing (NGS) technology was used to generate sequence datasets from citrus affected by two such diseases: citrus chlorotic dwarf (CCDD) (whitefly-transmitted) and yellow vein clearing disease...

Besides emerging evidence of new Stolbur phytoplasma vectors, Hyalesthes obsoletus is still considered the main vector of bois noir in Baden region, SW-Germany. Recently, habitat models were developed to study the habitat requirements of the planthopper vector. Vectoring the yellow disease...

Cereal aphids, Sitobion avenae, have developed resistance to pyrethroids in the last few years, culminating in control failure at some locations in England 2011 and 2012, associated in the latter year with local epidemics of barley yellow dwarf virus (BYDV). Studies by Rothamsted Research and...

The common blossom thrips, Frankliniella schultzei (Trybom), has been recently reported as an agronomic pest in South Florida. It poses a serious threat to tomato and pepper growers due to its ability to transmit Groundnut ring spot virus (GRSV). In the wake of the current problem 3 trials were...

In the period of 2011-12, in the context of Decree on the implementation of measures for the suppression and spread of Grapevine flavescence doree and suppression of the leafhopper (Scaphoideus titanus Ball) in the wine-growing region of Posavje, detailed study of the bionomics and the success of...

The invasive leafhopper Scaphoideus titanus is spreading in Europe from ca. 35 to 50°N. According to the origin area of this insect, we hypothesized that its Southern limit of distribution could partly be the consequence of the lack of cold temperatures that are essential to break egg diapause. We...

This paper deals with the study and management of the Grape leafhopper Scaphoideus titanus Ball, vector of the Candidatus Phytoplasma vitis pathogen, in vineyards located in Southern Switzerland. S. titanus is an invasive species of North American origin that became a component of a complex...
