| Abstract | ||||
| Theridion spinitarse was described as a new species for the first time from female by O. Pickard-Cambridge, 1876, then Knoflach, et al. (2009) re-described this species from female specimens. Spider specimens were collected from mango trees in Fayoum Governorate and from grapes at El-Sadat sector of Menoufia Governorate. Individuals of the spider were rearedand biological aspects were studied under laboratory conditions ( 25°C and 60-70% R.H). Individuals of this species fed every two days on second larval stage of Spodoptera littoralis (Boisduval 1833). Males and females reached maturity in the fifth spiderling stage after 67 & 72.27 days, respectively. Adult longevity, lifespan, fecundity of female and food consumption were also studied. | ||||
