Abstract—Crataegus monogyna Jacq. (Rosaceae) is recorded as a host plant of Balcanocerus balcanicus (Horväth, 1903) (Homoptera, Cicadellidae, Idiocerinae). A trophobiotic association between the leafhopper and 5 species of ants of the family Formicidae, namely Lasius alienus (Forst.), L. fuliginosus (Latr.), L. niger (L.), Formica pratensis Retz, a...

Reports on ant-attendance in the leafhopper family Cicadellidae (Hemiptera: Cicadomorpha) are rare and mainly concern species from the tropics and subtropics. We documented trophobiotic relationships between leafhoppers Hephathus freyi (Fieber, 1868), H. nanus (Herrich-Schäffer, 1835) (Macropsinae), Balcanocerus balcanicus (Horváth, 1903) (Idioceri...

Background Bulgarian planthopper fauna (Hemiptera: Fulgoromorpha) are relatively well studied, with 164 known species from 77 genera and 11 families. Data for some species from previous studies were reported without any localities or were incomplete and need to be updated. New information In the present study, 13 species of planthoppers are recorde...

The labelling of entomological material is a labour-intensive and time-consuming task, often carried out by staff who are over-qualified for the task. This paper introduces a small automation step that speeds up this process via a method that uses a low-cost cutting plotter. The following text will present a financial and temporal analysis of the i...

The superfamily Cercopoidea (spittlebugs), an insect group in the suborder Auchenorrhyncha (Hemiptera), is represented in Europe by two families – Cercopidae and Aphrophoridae. Currently there are 18 species – 5 of cercopids and 13 of aphrophorids, known in Bulgaria. Two of them – Haematoloma dorsata (Ahrens, 1812) and Aphrophora costalis (Matsumur...

Jumping plant-lice (Hemiptera, Sternorrhyncha, Psylloidea) are small phloem-feeding insects. With about 400 species distributed in Europe, the European fauna is considered well-studied. However, information on psyllids occurring in the eastern Balkan Peninsula is insufficient. So far, less than a hundred psyllid species are known for Bulgaria, most...

For over 160 years, the cicadas inhabiting the Maltese Islands were assigned to the widespread European species Cicada orni Linnaeus. However, analysis of their calling song reveals with certainty that the taxon known to occur in the archipelago is, in fact, the sibling species Cicada barbara Stål.

Hemipteran material collected from the Maltese Islands has yielded eleven species previously unrecorded, belonging to three different suborders as follows: nine new records of Auchenorrhyncha (Bursinia sicula Emeljanov, Chloriona sicula Matsumura, Eupteryx zelleri (Kirschbaum), Euscelis cf. ohausi Wagner, Opsius cypriacus Lindberg, Paralimnus phrag...

The Asian citrus psyllid Diaphorina citri (Hemiptera: Psylloidea) is a serious pest of citrus species worldwide because it transmits Candidatus Liberibacter spp. (Alphaproteobacteria: Rhizobiales), the causative agents of the incurable citrus disease, huanglongbing or greening disease. Diaphorina citri possesses a specialized organ called a bacteri...

New data on the distribution of Phytoecia argus (G. F. Frölich, 1793) (Cerambycidae: Lamiinae) in Bulgaria are presented. Six specimens were collected by net sweeping and by hand collection around the host plant Trinia glauca (L.) Dumort. in steppe grasslands in Chepan Mts. The species is probably more widespread in suitable habitats in Western Bul...

As a result of human activities invasive insect species are spreading rapidly in new territories. Turkey doesn't make an exception to this process. One of the most important invasive species belongs to Ricanidae family. In Turkey there are probably two native species: Ricania ayle Dlabola, 1983 and Ricania hedenborgi Stål, 1865. Orosanga japonica M...

The complex of longhorn beetles in Bulgarian and North Macedonian parts of Belasitsa Mt. was studied by literature data and original biological materials. As a result, 110 taxa from six subfamilies were established, as follows: Prioninae (3 species), Lepturinae (33 species and subspecies), Necydalinae (1 species), Spondylidinae (1 subspecies), Cera...
