The cost-reliability of five sampling methods (visual search, drop cloth, beat bucket, shake bucket, and sweep net) was determined for four groups of predatory arthropods on cotton plants in Texas. The beat bucket sample method was the most cost-reliable sampling method for Orius adults, and the beat bucket and drop cloth were the most cost-reliable methods for Orius nymphs. The drop cloth and ...

The aim of this study which was carried out from March 2003-February 2004 was to determine the parasites of carp (Cyprinus carpio L., 1758) inhabiting the Kovada Lake. During the study, a total of 63 common carps were caught in different regions of Kovada Lake each month and investigated parasitologically. In carps, the ectoparasite, Dactylogyrus minutus of Monogenea, was found and endoparasite...

Pest control in agriculture employs diverse strategies, among which the use of predatory insects has steadily increased. The use of several species within the genus Orius in pest control is widely spread, particularly in Mediterranean Europe. Commercial mass rearing of predatory insects is costly, and research efforts have concentrated on diet manipulation and selective breeding to reduce costs...

The effect of moisture source and diet on the development and reproduction of the pirate bugs, Orius thripoborus (Hesse) and Orius naivashae (Poppius) (Hemiptera: Anthocoridae) was examined in the laboratory. Both species had been collected in and around sugarcane fields in South Africa. Supplementing eggs of the flour moth Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae) with a green bean...

In this study, we examined the morphology, genetics and distribution of members Merodon chalybeus subgroup (M. aureus species group): M. Wiedemann in Meigen, 1822, minutus Strobl, 1893 robustus Veselić, Vujić & Radenković, 2017. Two species, minutus, are morphologically very similar often misidentified literature. Here, by employing an integrative taxonomic approach provide strong evidence for ...

Establishing how invasive species impact upon pre-existing species is a fundamental question in ecology and conservation biology. The greater white-toothed shrew (Crocidura russula) is an invasive species in Ireland that was first recorded in 2007 and which, according to initial data, may be limiting the abundance/distribution of the pygmy shrew (Sorex minutus), previously Ireland's only shrew ...

The removal and biodegradation of nonylphenol (NP) by four freshwater microalgae, including three green algae (Scendesmus quadriauda, Chlorella vulgaris, and Ankistrodesmus acicularis) and one cyanobacterium (Chroococcus minutus) were studied in bacteria-free cultures exposed to different concentrations of NP for 5 days. All four algal species showed a rapid and high ability to remove NP (inclu...

We examined sequence variation in the mitochondrial cytochrome b gene (1140 bp, n = 73) and control region (842–851 bp, n = 74) in the Eurasian harvest mouse (Micromys minutus (Pallas, 1771)), with samples drawn from across its range, from Western Europe to Japan. Phylogeographic analyses revealed region-specific haplotype groupings combined with overall low levels of inter-regional genetic div...

The occurrence of the myxosporean parasite Kudoa camarguensis was surveyed monthly during 1997 in a brackish-water lagoon of the Rhĵne River delta (France). K. camarguensis was found on its typical host, Pomatoschistus microps, and on an additional host, P. minutus. Prevalence and mean abundance were higher in the typical host than in the additional host due to differences in the temporal occup...
