The objective of this research was to determine the effect of corn removal for silage on rootworm oviposition and on the resulting populations and damage the following years. If the corn is removed before oviposition occurs, and if the beetles go elsewhere to lay their eggs, damage to the corn roots the following spring should be prevented. This would save farmers insecticide costs the following year. To determine how adult populations present in the corn field in late summer and fall affect damage to the corn the following spring, corn vegetation was removed on different dates encompassing the time oviposition was taking place. The damage to the corn from the resulting rootworm populations was correlated to the corn removal dates as affected by fall and spring plowing.
