7.Major Rice Diseases and Insect Pests and Integrated Control.
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...
The efficacy of a brief exposure (1, 7, and 10 days) to a nitrogen-controlled atmosphere (N-CA) for major storage pests in a field validation study in the Czech Republic is reported. The main goal wa...
Pitfall trapping studies are available for particular stored grain pest species. In small farms, the stored grain pest control strategy is rarely species-specific but is often “pest ecological-group-s...
Invisible to the naked eye, plant-parasitic nematodes are a huge threat to agriculture, causing billions in crop losses every year. Plant scientists at the University of Missouri and the Uni...
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 ...
The noctuid C. trapezina (CT) has been considered an occasional predator of other Lepidoptera larvae. Functional/numerical response of predator and/or prey was estimated using 27 years of time-series ...
In every scientific discipline the precise and rational communication of scientific information is based primarily on generally accepted, easily available and published nomenclature. Plant medicine,...
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. ...
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 ...
Our research was realised on spring barley and winter wheat in Nitra-Dolná Malanta during 2004–2006. We found that the total occurrence of the pests had decreasing tendency. The flea beetle (Phyllot...
The study compares two methods for modeling the potential distribution of pests when applied to the European corn borer (Ostrinia nubilalis Hubner). The development of the European corn borer (ECB) is...
The toxicity of three concentrations (5%, 10% and 20% w/v) and spraying schedules (2, 4 and 6 weekly applications) of an extract from West African black pepper, Piper guineense, for managing two major...
The species composition, frequency and abundance of insect pests (Coleoptera) occurring outside a grain store were explored. Wheat bait traps were used for pest monitoring; they were changed every mon...
The insecticidal efficacy of aqueous extracts of five Nigerian spices (Piper guineense Schum and Thonn., Aframomum melegueta (Roscoe), Xylopia aethiopica (Dunal) A. Rich., Zingiber officinale L. and C...
