Abstract
The reproductive activity of Calliptamus barbarus and Calliptamus wattenwylianus was investigated to understand population dynamics and reproductive potential in a subhumid bioclimatic zone. Specimens were collected from July to October and dissected to assess ovarian development and egg-laying activity. The number of ovarioles, determined at birth, ranged from 62 to 67 for C. wattenwylianus and 48 to 58 for C. barbarus. Higher fertility was observed in C. wattenwylianus, with egg production increasing during the first oviposition for both species. The average reproductive yield was notable for C. barbarus (85.99%) and C. wattenwylianus (86.56%). Oocyte resorption occurred mainly during drought (August-September) and cold periods (October-November). C. wattenwylianus females reached maturity earlier, beginning in August, compared to C. barbarus. Egg production began in July for C. wattenwylianus and in September for C. barbarus. Oocyte retention rates were 5% for C. barbarus and 9% for C. wattenwylianus. These findings provide insights into reproductive patterns in North African Orthoptera, with implications for pest control in subhumid regions.
