Abstract
The density of the phytophagous curculionid weevil complex belonging to one family and four subfamilies was determined in three different ecotypes including date‐palm, vegetable and natural (fallow) habitats in Western Saudi Arabia. Different densities were observed in the three habitats during 1996–1997. However, the date palm habitat showed high number of curculionid weevils. This may be attributed to the availability of food source, vegetational cover and shaded environment in the available niche. Chi square test showed that there were significant differences in density numbers between the three habitats. Three peaks were observed in the date‐palm habitat during December, March and May.
