Patterns of relationships between certain leafhoppers and plants. part ii. role of sensory stimuli in orientation and feeding
1974
SAXENA, K.N. | SAXENA, R.C.
The orientational and feeding responses of E. devastans are determined by stimuli some of which are unspecific and others specific to the host (cotton) and nonhost (castor) plants. The green colour and humidity stimuli are unspecific and attract the leafhopper equally strongly to both the plants. Their odour is specific to each. The odour of the host (cotton) including that of its constituents camphene and α-pinene attracts while the nonhost (castor) odour repels the leafhopper. After its arrival, unspecific mechanical contact stimuli elicit the insect's proboscis response, followed by ingestion which is determined by certain unspecific gustatory stimuli e.g., sucrose and glucose. Ingestion is further increased by the specific odour of the host (cotton) but not of the nonhost (castor) plants, resulting in a greater food-intake from the former.
