The line was fitted by loess to the baseline days. No such correlation was detected in loess fields. A similar, but non-significant, trend was evident on loess. The lack of correlation between infestation parameters on loess may be due to high larval mortality caused by the relatively high moisture content of this soil type. Alternatively, infested tubers in loess may support more larvae than those in sand, possibly because cracks in loess soil make the tubers accessible to more larvae. Due to their locations in decalcified loess sediments no organic material has been preserved and data on subsistence activities or the season(s) of occupation are absent. In addition, larval infestation of leaves collected from the margins of a sandy field exceeded infestation of leaves from the margins of a loess field by a factor of three. Lines are based on loess. No such correlation was detected in loess. The line is a loess fit. Line is based on loess. As a result, the typical small patio hillsides and the streaked loess sunken roads typical of the region came into being.
