Abstract
The common cuckoo (Cuculus canorus) is an obligate interspecific brood parasite. I report the first observations of two young cuckoos in two different clutches of the same pair of black redstarts (Phoenicurus ochruros) in same year, 2007. I found a young cuckoo in the grape-growing area of Andra{evec (46º00’N, 15º57’E; north-western Croatia), on May 25 (first clutch) and June 30 (second clutch), 2007. According to my previous findings, a pair of black redstarts lays the clutches in the same nest during one year. The nest was situated on the inner beam of a wooden vineyard hut.

Abstract
The aim of this study is to determine the plants used as brooms by individuals and municipal authorities in some Southeast European (Bulgaria and Turkey) and West Asian (Azerbaijan, Saudi Arabia and Yemen) countries. The study was carried out from 1999 to 2005. At the end of the study, it was identified that 19 plant taxa belonging to 12 different families were used as brooms in the five countries. Among these species, Sorghum bicolor (broomcorn) was determined to be used extensively by municipal authorities for sweeping streets (Bulgaria) and by individuals for houses (Turkey and Azerbaijan). Erica sp. (tree heath) is commonly preferred by municipal authorities for sweeping streets in many areas of Turkey. We have established that the panicles and above ground parts of these plants are mostly used as brooms. Asteraceae is the largest family, represented by five species used as brooms. It is followed by Plumbaginaceae and by Poaceae with two species.

Abstract
Pomatias rivularis (Eichwald, 1829) specimens were collected on Bansko Brdo (or Bansko Hill, Baranya, Croatia) during spring 2007. This species proved to be new for the Croatian fauna. Populations of Pomatias elegans (O. F. Müller, 1774) were also found on Bansko Brdo, which is the only known area in Croatia where both these two species occur. The list of 40 mollusc species (35 snails, 5 bivalves) identified in the study area is presented. Among them, Ena montana (Draparnaud, 1801) was found for the first time in the NE part of the country.

Abstract
A check list of whiteflies in Croatia is presented, with a list of references and the results by authors from the period 2005-2007, performed for the first time in Croatia ([IMALA, 2008). In the reference list, 10 species have been described. 31 different whitefly species were identified by our own faunistic investigations, 21 of which are new for the Croatian fauna. These are the following species: Aleurochiton acerinus Haupt, 1934; Aleurochiton pseudoplatani Visnya, 1936; Aleuroclava hikosanensis Takahashi, 1938; Aleuroclava jasmini Takahashi, 1932; Aleurolobus wunni Ryberg, 1938; Aleurotuba jelinekii Frauenfeld, 1867; Aleuroviggianus adrianae Iaccarino, 1982; Aleyrodes asari Schrank, 1801; Aleyrodes elevatus Silvestri, 1934; Aleyrodes lonicerae Walker, 1852; Asterobemisia carpini Koch, 1857; Asterobemisia obenbergeri Zahradnik, 1961; Asterobemisia paveli Zahradnik, 1961; Bemisia afer Priesner & Hosny, 1934; Massilieurodes chittendeni Laing, 1928; Massilieurodes setiger Goux, 1939; Neopealius rubi Takahashi, 1954; Simplaleurodes hemisphaerica Goux, 1945; Siphoninus immaculatus Heeger, 1856; Tetraleurodes hederae Goux, 1939 and Tetralicia ericae Harrison, 1917. The check list contains 31 whitefly species from a single subfamily, Aleyrodinae, categorised in 18 genera.

Abstract
This paper deals with the scale insects Planococcus citri (Risso, 1813), Planococcus ficus (Signoret, 1875) and Planococcus vovae (Nasonov 1908) monitored during a four year faunistic investigation (2005–2008) of the genus Planococcus Ferris, 1950 in Croatia. P. vovae is a new species for Croatia. Distribution (according to UTM system) and host plants of these species in Croatia are reported. Some morphological characters useful for the differentiation of these three species are also described.

Abstract
In this paper the results of a ten year investigation of mosquitoes using dry ice baited CDC traps in the city of Osijek, Croatia are presented. In the first year we recorded 16 species. During these ten years the total of 20 species were determined. The single method, dry ice baited CDC traps, makes it possible to determine almost the entire fauna in a given area. The estimated fauna is statistically calculated. Five non-parametric estimators were chosen for evaluation: one-factorial Jackknife (Jackknife-1); two-factorial Jackknife (Jackknife-2); one-factorial Chao (Chao-1); two-factorial Chao (Chao-2) and Bootstrap. The estimated fauna contains between 22 and 29 species. The method used turned out to be very good when used over a long period of time, because new species were registered even in years without many mosquitoes.
