    Opis:
    Little is known about the impact of exotic invasive plant species on soil invertebrate communities. The influence of highly productive invader Reynoutria sachalinensis on the soil microarthropods was studied. Three sites, with different coverage of the invader, have been selected in the mixed forest in the Jura Krakowsko-Częstochowska. The lowest abundance of microarthropods and the lowest oribatid species richness were noted in the monospecific Reynoutria infestation stand. The reduction of abundance of saprophagous mites (Oribatida, Acaridida) and springtails were observed at the totally invaded site, whereas gamasid and actinedid mites reacted positively to the presence of Reynoutria. Observed abundances and species richness of microarthropods at studied sites were in accordance with theories on biodiversity. Antifungal activity of phenolic compounds present in leaves of R. sachalinensis may negatively influence on saprophagous representatives of microarthropods. On the other hand, predacious mites profited from the simplified vegetation structure.

    Opis:
    In this study the effect of different grassland managements (cattle grazing with different intensities and mowing) on soil mesofauna, i.e. mites (Acari) and springtails (Collembola), was studied. Mites and springtails are the most numerous representatives of soil mesofauna organisms living in the upper soil layers (up to 5 cm). Soil mesofauna groups or species are commonly used as bioindicators of soil health. The experiment was carried out from 2007 to 2009 in the West Sudety Mountains, Poland. Pastures and meadows were under organic farming management, without pesticides or synthetic fertilizers, and restricted livestock density. Soil samples were taken three times a year (in May−June, July and October) from pastures grazed at different frequencies: once, twice and four times a year, alternate management (grazed and mown pasture) and mown meadow. Mites were identified according to orders or suborders (Oribatida, Gamasida, Prostigmata, Astigmata), while springtails to the species level. The data were analysed using a general linear model (GLM). The mesofauna taxa in relation to the treatment and date were analysed with the canonical correspondence analysis (CCA). The data from three years showed that most soil mesofauna assemblages occurred in significantly higher numbers on the pasture grazed once or twice and on alternate managed pasture than in pasture grazed four times a year and mown meadow. The CCA analysis showed the preference of most springtail species to pasture grazed once a year, while mites preferred pasture grazed twice a year and alternate management. The number of species and the abundance of the most numerous species (Protaphorura pannonica, Desoria multisetis and Folsomides parvulus) did not differ significantly between treatments. To summarize, cattle grazing once or twice a season or alternate management (grazing and mowing once a season) have a positive impact on soil mesofauna.

    Opis:
    Investigations into the abundance of adult D. reticulatus in relation to the effect of climatic conditions (temperature, humidity) on host-seeking behaviour were conducted during the autumn (September-October) and spring (May) activity peaks in 2008–2009 in eastern Poland (51°25’N). The study was conducted in the same habitat where similar examinations were performed in 1999–2000. A comparative analysis revealed that the abundance of D. reticulatus had almost doubled within 10 years. Analysis of data on the humidity and temperature conditions prevailing during tick collection, and on tick abundance in the respective study periods in 1999–2000 and 2008–2009, as well as absence of climatic changes over many years, indicate that the increase in the numbers of ticks may have been a result of a multitude of other factors, e.g. weather or environmental conditions favourable for ticks and their hosts. The substantial differences in D. reticulatus abundance observed during the autumn activity peak (an increase from 126 and 128.6 specimens per collection in 1999 and 2000, respectively, to 247.3 in 2008) demonstrate the considerable effect of the biotic and abiotic conditions prevailing during the development of young and adult stages on the abundance of this tick species. The activity of adult D. reticulatus ticks in the autumn was 2.7-fold higher in comparison to that observed during the spring collection; the difference was statistically significant (p<0.0001). Females dominated in both seasonal activity peaks. The ratio between females and males during the spring and autumn peaks was 3.31:1 and 1.05:1, respectively. The increase in the abundance of the D. reticulatus population implies a higher risk of transmission of tick-borne diseases in the study area, and the necessity to develop and implement effective prevention methods and tick control programmes.

    Opis:
    This study assessed the insect pest infestation of tomato during 2011 and 2012 in three localities namely Bula Kuliye, Kajeri and Soye of Bama Local Government Area, Borno State, Nigeria. Fifty plants were randomly checked per farmers’ field for insect pest recovery and count. Sampling was carried out in five to nine farmers’ fields per locality. With 38-52 %, 9-62 %, 13-39 % and 5-9 % species composition respectively across localities, Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) followed by Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) were more predominant insect pests of tomato in these localities over Tetranychus sp. (Acari: Tetranichidae) and Spodoptera litoralis (Boisd.) (Lepidoptera: Noctuidae). Total proportion of infested tomato plants per farmers’ field ranged from 19-36 %, and was significantly higher in Bula Kuliye and Kajeri than in Soye. Total number of insect pests per plant/leave and bored fruits per farmers’ field fell between 2-5 and 21-35, and likewise, was higher in Bula Kuliye and Kajeri than in Soye. Although tomato plant infestation and fruit damage were found to be moderate or high in these localities, future studies on the bionomics or population dynamics of these insects remain essential for establishing their economic status.
