MONITORING OF FLIGHT PHENOLOGY OF RASPBERRY CANE MIDGE RESSELIELLA THEOBALDI BARNES (DIPTERA: CECIDOMYIIDAE) BY PHEROMONE TRAPS IN WESTERN SERBIA

The flight phenology of the raspberry cane midge Resseliella (Thomasiniana) theobaldi Barnes (Diptera, Cecidomyiidae) was monitored over three successive years (2006-2008) in a raspberry orchard of the Fruit Research Institute Čačak, at the 'Zdravljak' site. This was the first time that large white delta traps baited with the raspberry cane midge sex pheromone were used. No insecticides were used during the monitoring period. Throughout the period, over three growing seasons, the midge presence was detected from April-May to September-October. During the three years, there were variations in the numbers of midges caught per trap, as well as those in the total numbers of midges trapped across years and peak numbers per trap. The highest total number (2,419) of midges during the season and the highest number of midges per trap in a sample (729) were recorded in 2007. The earliest maximum catch per trap (729) occurred on 11 May, 2007

A CONTRIBUTION TO THE KNOWLEDGE OF DISTRIBUTION OF THE SPECIES PRENOLEPIS NITENS (MAYR, 1853) (HYMENOPTERA: FORMICIDAE) IN THE SOUTHWEST PART OF THE BALKAN PENINSULA

Study of myrmecofauna in the southwest part of the Balkan Peninsula has a long tradition but it is also characterised by a small number of studies of exclusively faunistic character. Analysis of material collected at Popovo Polje yielded the first record of Prenolepis nitens (Mayr, 1853) in Bosnia and Herzegovina. Subsequent analysis of literature data showed that the species inhabits all of the countries of the western Balkans: Slovenia (Ljubljana), Croatia (wider area of Zagreb and Dalmatia), Montenegro (Kotor) and Serbia (Stara planina). Discovery of Prenolepis nitens (Mayr, 1853) in Bosnia and Herzegovina represents irrefutable evidence of continuity in the distribution area of the species along the southern boarder of the Balkan peninsula and it also makes a significant contribution to the knowledge of distribution of Prenolepis nitens (Mayr, 1853) species across the surveyed area

ODONATA FROM BULGARIA IN THE COLLECTION OF NATIONAL MUSEUM OF BOSNIA AND HERZEGOVINA

The entomological collection of the National Museum of Bosnia and Herzegovina is one of the oldest Balkan insect collections. Eighty-seven (87) dragonfly specimens from 19 species that originate from Bulgaria were found in this collection. In this paper we present the oldest and till now unknown records of dragonflies from Bulgaria from this collection. Some interesting and new distribution data on several species are also presented and discussed
