| Abstract |
The activity-density of the surface soil fauna sampled in four different cultivations: tomato intercropped with squash, tomato intercropped with pumpkin, tomato left alone with wide space between rows after cutting squash (monocultured tomato) and squash planted lately with dense tomato (time of population) were compared. This study was carried out at sennourus village, Fayoum governorate. The samples were taken each week from two plots for one summer season. The following remarks summarize the results: 1)Insect survey revealed the occurrence of 11 orders, 34 families and at least 44 species of arthropods associated with four different cultivation system. 2)The intercropping of tomato with pumpkin was the most suitable cultural system for reducing the numbers of mesofauna visiting plants. 3)Retardation of squash plants 60 days after tomato planting was accompanied by an obvious increase in arthropods reaching 369 individuals which is more than twice the individuals collected from the intercroppiong system which were 146& 135 individuals for tomato planted with squash and sole tomato respectively and more than three time for tomato intercropped with pumpkin. 4)Fauna collected fall under 6 categories: herbivores, detrivores, predators, parasites, pollen grain transmittes and vector diseases. 5)Community composition was determined through the period of study using the Shannon-Wiener and Simpson indices of diversity, a slight difference in the species diversity among the four types of cultivations was observed was observed.
