Reproductive potential response to continuous rearing of Hypothenemus hampei (Coleoptera: Scolytidae) developed using Cenibroca-artificial diet

The artificial diet called CENIBROCA was developed for culturing Hypothenemus hampei (Ferrari). The diet consists of casein, power yeast, industrial agar, and ground green coffee and some antimicrobial agents. It was suitable for rearing CBB throughfive generations in the laboratory. This generations were obtained without any significant differences in fecundity (alpha=0.05), but they were affected in fertility. The values of net maternity, oviposition percentage and flying activity obtained from first to fifth generation were compared with the values of CBB from the field (control), which were reared under the same laboratory condition. The fecundity was significantly affected, the highest value (35.6°SD=12.8) was obtained in CBB from the field, which was significantly different from the others (alpha minor who 0.05). The second highest value occurred in the first generation with 25.1°12.7, followed for second, third, fourth and fifth generations with 23.6°SD=14.3, 24.0°SD=11.3, 20.4°SD=15.9 and 21.2°SD=14.3, respectively (alpha=0.05). The lowest value of gross fertility was calculated for the fifth generation. The maximum value of net maternity was for CBB from the field.
