The Ineffectiveness of Landscape Diversity Index in Biocontrol: An Evidence from Small Scale Farmland

Abstract:

Landscape diversity index behaves ineffective in small scale farmland. The correlation coefficients between Shannon's diversity index as well as Simpson's diversity index with the population density of ladybeetles are negative. This result is opposite with the results from large scale farmland in developed countries. Landscape pattern has significant influence on the population density of ladybeetles. Especially the cotton/wheat relay intercrops have significant influence on the population density of ladybeetles. Besides grassland are also beneficial to the population density of ladybeetles.
