| species composition of leaf beetle assemblages in the canopies of apple and pear orchards in hungary and great britain (coleoptera: chrysomelidae). | the species richness and species composition of coleoptera assemblages were investigated in the canopies of apple and pear orchards in hungary and in the apple orchards in great britain. the investigations were carried out in hungary (nagykovácsi: 3 plots, kecskemét: 5 plots, sárospatak: 4 plots) between 1990-94, and in great britain in kent (east malling, marden and robertsbridge) in 2001 and 2002. former investigations in hungary revealed that the diversity of coleoptera assemblages in the can ... | 2004 | 15759432 |
| effects of seed coatings with thiamethoxam on germination and flea beetle control in flax. | flea beetles damage the seedlings before and after emergence and later the top of the plants as well, resulting in forking of the stem. this is unacceptable for the flax fibre industry, since it influences fibre quality negatively. five field trials were carried out in 2001, 2003 and 2004 to assess the control of the flax flea beetles longitarsus parvulus (payk) and the large flax flea beetle aphthona euphorbiae (schrank) by film coating the seeds with thiamethoxam in fibre flax crops (linum usi ... | 2007 | 18399492 |
