Agroforestry can provide ecosystem services and benefits such as soil erosion control, microclimate modification for yield enhancement, economic diversification, livestock production and well-being, a...
An experimental trial was conducted to determine the pathogenicity of Beauveria bassiana strain 202 (Bb-202) against multiple targeted sucking insect species that are serious pests of crops and ornam...
Context: Insects can be the cause of major ecological problems; they can transmit microbes and parasites that affect humans, and damage food crops, trees, and homes. The total economic cost of insect-...
The present paper is about the provenance and family diversity of insect occurrence on the offspring of 58 pedunculate oak (Quercus robur L.) trees representing 5 populations from the Polish range of ...
Research on merocoenoses of cambioxylophagous insect fauna of Norway spruce (Picea abies [L.] Karst.) was carried out in spruce stands of different age in the area with an endemic population (Moravian...
The paper deals with the occurrence of fungi and rusts, viruses and insects on main woody species in riparian stands along the middle courses of the Slatina and Hron rivers in Slovakia in 2002–2004. ...
Research was carried out in 7 model urban areas of Slovakia (Nitra, Topoľčany, Komárno, Partizánske, Piešťany, Prievidza, Trnava) in 2005–2006. Research was aimed at phytophagous i...
During 1997–1999, the damage and mortality caused by insect herbivores to pigweed (Chenopodium album) and wild buckwheat (Fallopia convolvulus) were studied in an early fallow field at Prague-Ruzyně. ...
Insect pests, as widely tolerant and adaptable organisms, may be less distinctly affected by climate change than other insect species. The changing climate may affect the occurrence and impact of the ...
