Abstract
True spiders have an important role in the biological control against the pests of
the corn crops. Therefore, propagation of this community is needed. The purpose of
the present study is to find a simple method for increasing the numbers of the
members of this community in the Egyptian Delta corn fields focusing on the type
of fertilizer. Both chemical and organic fertilizers were applied on an unsprayed
corn field at Kafr El-Sheikh Governorate, Egypt at the experimental farm of Sakha
Agricultural Research Station. The results revealed that spatial and temporal
distributions in the field fertilized by farmyard manure were higher (18 genera belong to 11 families) compared with those in mineral fertilized field
(10 genera belong to 7 families). Web-building spiders were more abundant than the
hunting spiders in case of the farmyard manure and the dominant families were
Linyphiidae, Philodromidae, Lycosidae, Araneidae, Theridiidae and Tetragnathidae.
This study reflects the probable indirect effect of the fertilizer's type in terms
of biological control and the role of the spiders against pests of the corn crops.
