Effect of food plants on the volume of repellent secretion obtained in adult Zonocerus variegatus (Orthoptera: Pyrgomorphidae).
The volume of secretion obtained from adult Zonocerus variegatus (Orthoptera: Pyrgomorphidae) was influenced by the type of food plants. Insects fed on leaves of cassava Manihot esculenta, bitter leaves Vernonia amygdalina, and a mixture of M. esculenta and Acalypha wilkesiana gave a good volume of secretion while Chromolaena odorata, Elaeis guinensis, Aspilia africana and Citrus sinensis did not favour secretion production. No significant difference was recorded in the volume of secretion obtained from Z. variegatus from the two seasons irrespective of the food plant. Similarly, food plants gave no significant difference on the volume of secretion between the two seasons.
