- Abstract
[ Objective]The structure of agricultural landscape will affect the species composition and spatial distribution of insects, and the change of the spatial distribution pattern of ecological landscape can be one of the effective strategies in species protection and management. [Method] Taken Karamay development zone as tested area, using the Landsat data and the insect population density, the quantities of overwintering pupae and control efficiency of Apocheima cinerarius based on field work, and the effects of the changes in the ecological landscape pattern on the distribution characteristics of Apocheima cinerarius were analyzed. [ Result] ( i) From the perspective of the type of ecological landscape, Apocheima cillerarius was distributed in areas with concentrated woodland, mainly near the 45 degree north latitude and the 84 degree east longitude. (ii) Most of the sampling points showed a decreasing trend in the overwintering pupae within three years. However the data of overwintering pupae in the spring showed slight changes during the there years. ( iii ) From the perspective of the type level, the area of the woodland landscape increased and then decreased slightly, but the TE of the woodland landscape increased significantly, the woodland landscape was scattered and distributed with high fragmentation in 2015 ; ( iv) Fragmentation was a necessary environmental condition that could effectively interfere and destroy the survival of Apocheima cinerarius. The weaker the continuity and integrity of the plaque was, the more effectively it could curb the distribution of Apocheima cillerarius. [ Conclusion] The fragmentation and aggregation degree of the forest ecological landscape will directly drive the spatial and temporal distribution of the Apocheima cinerarius, while other types of landscapes will also indirectly to do so. However, there are many factors that affect the spatial distribution of Apocheima cinerarius, which are worthy further reasearch.
