【Abstract】 The respiration of the diamondback moth( Plutella xylostella L.) infected by Beauveria bassiana was determined by Infra red CO 2 gas analyzer. The results showed that the pattern of respiratory rhythm of diamondback moth belonged to variable amplitude oscillated type; the CO 2 output of infected insects was significantly lower than the control. The results indicated that the metabolism of the treated larvae was interfered with and the respiratory metabolism level was decreased.更多还原
