Suppression of adult lesser mealworm (Coleoptera: Tenebrionidae) using soil incorporation of poultry manure.
The effectiveness of manure incorporation in reducing the numbers of adult lesser mealworms emerging from caged-layer poultry manure applied to agricultural fields was examined in summer 2002 and 2004. Incorporation treatments included control (no incorporation), disk (7-cm depth), harrow (15-cm depth), chisel plow (30-cm depth), and moldboard plow (33-cm depth) on silt loam soils in New York state. An estimated 55,192 and 183,500 live adult lesser mealworms were applied to the field in 2002 and 2004, respectively. Mortality due to the action of the manure spreader was 32.4% in 2002 and 6.5% in 2004. No significant differences were observed between treatments in 2002. However, moldboard plowing significantly reduced beetle emergence compared with no tillage in 2004. Peak beetle flight was observed 10 and 17 d after manure application in 2002 and 2004, respectively.
