Abstract

Pitfall trapping was carried out in winter wheat at the Gödöllo University of Agricultural Sciences experimental farm, from the end of March, until harvest in mid-July, 1994. Dominant spider species of the survey was Pardosa agerstis (Westring). Out of the 1373 adult P. agrestis collected, there were 222 females. Of these 51 carried cocoons. Average number of eggs per cocoon was 72,43. Average number of larvae or pre-hatched spiderlings per cocoon (74,75) suggests that there is practically no mortality until the larval stage. Frequency distribution of the number of eggs per cocoon shows two peaks at the values of 69 and 84-85 eggs. The number of eggs per cocoon decreases from March until July. It is probable that P. agrestis produces two egg sacs from spring until harvest of winter wheat in Hungary.
