Pharmacological properties of the repellent secretion of Zonocerus variegatus (Orthoptera: Prygomorphidae)

Pharmacological properties of the repellent secretion of Zonocerus variegatus (Orthoptera: Prygomorphidae)

The odours of the whole body and the secretion of Zonocerus variegatus were easily recognised and perceived by human volunteers. However, the secretion odour is not related to the odour of the food plant consumed by the grasshopper. The repellency of Z. variegalus becomes more pronounced in the 6th....
