e0“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)”

Other claims from this paper (10)
- Observation Ground beetles and centipedes were the most commonly collected taxa in the sugarbeet plots during 2012 and 2013.
- Intervention effect Seed-applied insecticide did not affect centipede, spider and rove beetle activity densities.
- Intervention effect Plant density had a marginal effect on centipede activity density in 2012.
- Intervention effect Seed treatments did not affect ground beetle species richness, diversity or evenness.
- Intervention effect In 2013, ground beetle activity density was significantly higher in plots planted with untreated sugarbeet seeds.
- Intervention effect Sugarbeet root aphid populations were significantly higher in untreated plots in both years.
- Intervention effect Seed treatment decreased root aphid populations, but the reduction was not sufficient for adequate control.
- Intervention effect Sugar content was higher in the seed-applied insecticide plots in 2013.
- Intervention effect Seed-applied neonicotinoids and plant density had little impact on beneficial epigeal arthropod activity density.
- Mechanism Limited aphid control likely contributed to inconsistent effects of the treatments on yield parameters.
