Greenhouse studies were conducted to quantify the effects of feeding activity of selected densities of third instars, combined fourth and fifth instars, and adults of Euschtstus servus (Say) and E. variolarius (Palisot de Beauvois) on VE, V2, and V4 corn (Zea mays L.) Exposures of VE and V2 corn to all densities of third, fourth and fifth instars, or adults for 96 h resulted in termination of growth, reduced growth, or mortality of plants. There was no mortality of V4 plants. Third instars through adults caused tillering of VE and V2 corn, but only fourth and fifth instars and adults caused tillering of V4. Third instars through adults caused significantly shorter mean extended leaf heights of all growth stages. They also caused significantly lower dry root and aboveground weights of VE and V2 corn. Only adults caused significantly lower dry root weights of V4 plants. Corn growth stages and stink bug densities apparently affect the intensity of damage and may be important factors in assessing damage and determining control strategies.
