The Species Composition and Seasonal Dynamics of Thrips (Thysanoptera) Populations on Maize (Zea MaysL.) in Southeastern Poland: Thrips species composition and seasonal abundance was studied on maize crops during two seasons (2006-2007), in southeastern Poland. Altogether 21 species have been identified, among themFrankliniella tenuicornis(Uzel 1895) andHaplothrips aculeatus(Fabricius 1803) which are a graminicolous species and were eudominants, comprising 96.8% in 2006 and 82.0% in 2007 of all collected specimens. Other species occurred only in low numbers. The frequent and numerous presence ofF. tenuicornisspecies in their immature stages in the samples, confirmed the role of the maize plant as the host.H. aculeatusprobably chose maize as a food source and substitute plant for breeding.

Diabrotica VirgiferaLe Conte in Poland in 2005-2007 and Regulations in the Control of the Pest in 2008: Diabrotica virgiferaLe Conte has been present in Poland since 2005. The range of its distribution increased in 2006 and 2007.D. virgiferais known from areas of nine voivodeships in Southern and partially Central Poland. Current control strategy is based on containment measures to limit the spread of the pest from regions where it has occurred. This strategy includes the application of specific phytosanitary measures in defined parts of the country.
