Allow natural regeneration of ground cover beneath perennial crops
A site comparison study in two pear Pyrus spp. orchards in Daxing District, China (Beizhou et al. 2011) found that total numbers of natural enemies were similar between plots of naturally regenerated ground cover (averaging 337 individuals/year) and bare, tilled plots (306 individuals/year) during March to September, 2006-2008. Pest numbers were lower in regenerated (averaging 2113 individuals/year) than bare, tilled plots (3214 individuals/year). The seven-spot ladybird Coccinella septempunctata, predatory mite Phytoseiulus persimilis and green lacewing Chrysoperla sinica were the dominant natural enemies on ground cover plants and were more abundant in regenerated than tilled plots from around early June to mid-July. Three plots of 50 x 67 m in one orchard were allowed to grow natural grasses (Poaceae) and were compared with three plots of tilled bare ground in a separate orchard. Invertebrates were counted using visual surveys, canopy traps and sweeps of ground cover vegetation.
