Abstract

In this study, the egg production of the females with cocoon of Pardosa pullata (Clerck) collected from the Agricultural Biology Field Stations belonging to the University of Newcastle upon Tyne, U.K. was studied in the period of May-October in 1990 and 1991. The work was performed on a total of 379 cocoons collected with the females from an abandoned grassland, a small meadow and an unplowed field. The relations between body size and number of eggs, egg sac size and number of eggs, egg sac dry weight and female spider dry weight was investigated. The findings are as follows: The females produce egg sac more than one during the reproduction period; the first egg sacs contain more eggs than the second egg sacs; there is a po-sitive relation between the egg sac size and the number of egg deposited in it; there is no significant relation between the body size of the female and the quantity of the eggs produced.

Özet

Bu araştırmada, ingiltere-Newcastle upon Tyne Üniversitesi, Tanmsal Biyoloji Uygulama İstasyonlarından toplanan kokonlu dişilerde yumurta üretimi incelendi. Çalışma, 1990-91 yıllarının Mayıs-Ekim dönemlerinde terkedilmiş bir otlak, küçük bir mera ve nadasa bırakılmış bir tarladan toplanan 379 adet kokonlu Pardosa pullata (Clerck) dişisi üzerinde gerçekleştirildi. Araştırmada vücut büyüklüğü ile yumurta sayısı, yumurta kokonu büyüklüğü ile kapsadığı yumurta sayısı, yumurta kuru ağırlığı ile dişi örümcek vücut ağırlığı arasındaki ilişkiler araştırıldı. Dişilerin üreme periyodunda birden fazla kokon ürettikleri, ilk kokonlann sonrakilerden daha fazla yumurta içerdiği, kokon büyüklüğü ile kapsadığı yumurta sayısı arasında pozitif bir ilişkinin olduğu, ayrıca vücut büyüklüğü ile üretilen yumurta sayısı arasında ise anlamlı bir ilişkinin olmadığı tespit edildi.
