| response of pemphigus betae (hemiptera: aphididae) and beneficial epigeal arthropod communities to sugarbeet plant density and seed-applied insecticide in western nebraska. | this study investigated the impact of a neonicotinoid seed-applied insecticide (poncho beta) and two plant densities (86,487 and 61,776 plants per hectare) on the sugarbeet root aphid (pemphigus betae doane), beneficial epigeal arthropods, and selected crop yield parameters in sugarbeet (beta vulgaris l. var. vulgaris). ground beetles and centipedes were the most commonly collected taxa during 2012 and 2013, respectively. centipede, spider, and rove beetle activity densities were not affected by ... | 2017 | 28025226 |
