“…Larval development (four instars) and pupation are completed entirely within a single host seed. Adults emerge from the seeds through a "pupal window" leaving behind a typical hole and are able to mate and oviposit within a question of few hours (Dick and Credland, 1984). This species is easy to breed and handle, and laboratory colonies can be maintained in conditions similar to their anthropic Comparative Biochemistry and Physiology, Part B 168 (2014) [45][46][47][48][49][50][51][52] niche.…”

“…The variability in C. subinnotatus fecundity compared to data in the literature is also probably due to climatic conditions [19] and photoperiod that influence female oviposition and larval development with optimum spawning and development observed at 30 °C. It is also linked to the strain used as observed in C. maculatus [17,20]. The influence of climatic conditions on the fecundity of weevils was also reported in the sympatric species C. maculatus [19,21].…”

“…This strain was made from the offspring of adults collected in nature. The rearing was done by the method of Dick and Credland [17] in Plexiglas boxes in the laboratory at 30 ± 2 °C; 72 ± 2% RH and 12 h: 12 h LD. The temperature and relative humidity were recorded using a handheld thermohygrometer "Pen-Type".…”

Callosobruchus subinnotatus Pic. (Coleoptera: Bruchinae) is the most important depredator of Bambara groundnut seeds (Vigna subterranea Verd.) in West Africa. In view of an efficient control of its populations, some of the biological parameters of C. subinnotatus were determined under laboratory conditions (30 ± 2 °C; 72 ± 2% HR; 12h: 12h LD). The results have shown that the mean lifespan of females (11.36 ± 1.85 days) is shorter than that of males (15.14 ± 2.4 days). The female lays 80.83% eggs within the first 6 days after her emergence with a mean fecundity of 121.34 ± 27.62 eggs. The means egg fertility, survival and adult emergence rates are respectively 96.19 ± 1.45%, 97.72 ± 1.08% and 94.01 ± 2.14%. The sex ratio is in favor of males with a mean of 0.845 ± 0.08. The monitoring of adult emergence in connection with their reproductive status showed that the offspring of C. subinnotatus consists of two physiotypes, a reproductive type that appears during the first 8 days of emergence with a short development time (28.35 ± 3.36 days) and a non reproductive type that appears from the 9th day of emergence with a longer development time (37.92 ± 3.92 days).

“…Differences in biological traits among populations collected from different countries and/or continents have already been reported by numerous authors. For instance, [23] reported a significant variation in parameters associated with development and survival among three strains of C. maculatus from Brazil, the Yemen Arab Republic and Nigeria, infesting cowpeas. [24] observed a significant genetic differences in the preference of cowpeas and other legumes among strains of C. maculatus originated from different countries, and also indicated an inter-strains differences in fecundity in this species [24].…”

In this study, the biological parameters of two B. atrolineatus strains originated from two different agro-ecological areas of Niger are examined. The analysis of the adult lifetime showed that B. atrolineatus strain of the Sahelo-Sudanese area lived longer (7.58 ± 2.19 days) than that of the Sahelian area (7.44 ± 1.39 days). Furthermore, males lived longer than females regardless of the strain origin. The egg laying activity showed that the eggs laid number was not statistically different according to the two areas. But it appeared that more than 94% of the eggs were laid in the first four days of cowpea seed infestation. The larvae survival rate and the rate of emergence also varied according to the geographical strain origin. There were few data recorded in Sahelian area where nearly 30% of the larvae did not reach adult stage. In the Sahelo-Sudanese area, less than 4% of the hatched larvae reached the adult stage. The sex-ratio also varied according to the geographic strain origins. It was in favor of males in the Sahelian area and was in favor of females in the Sahelo-Sudanese area.
