The first three - spideding stages of male and female consumed an avenge of 320.5 & 382.5 individuals of the first prey, respectively, while the fourth to sixth stages of male and the fourth to seventh stages of female fed on 161.0 and 263.5 individuals of the second prey C capitan, respectively. The biological aspects including : 1-mating : 2-oviposition, 3-development, 4-adult longevity 5-generation period„ 6-sex ratio, 7-moulting, and 8-predation capacity were carried out. Male and female pass through six and seven immature stages (spiderlings), respectively before reaching adult with the life cycle averaged 99.0 & 123.0 days, respectively at 25 °C. | ||||
