| Abstract | ||||
| Theridion melanostictum O. P. Cambridge, 1876 (Araneae: Theridiidae) was collected from apple trees, El- Sadat city, El-Menofia governorate. Reared under laboratory conditions of 24-26°C and 60-70% R.H., males reached maturity after 4 spiderlings (instars); while females after 5 (instars). Spiders were fed every two days on the two preys, Tetranychus urticae Koch and larvae of Spodoptera littoralis (Boisd.). Total spiderlings averaged (105±2 and 136.6±3), (51.1±1.6 and 57.5z2.7) days for male and female when fed on T. urticae and S. littoralis, respectively. Life cycle, feeding behavior, food consumption and mating behavior were observed. | ||||
