摘要: SUMMARY In a turnip crop natural infection with mild yellows virus was greatest in two narrow zones, one to leeward of an artificial windbreak, the other long shallow depression earth. Both zones were approximately across wind when Myzus persicae flew early summer. Later summer, similar windbreaks facing different prevailing winds increased number larvae Scaptomyza apicalis on plants immediately and windward windbreaks, probably because shelter affected adults that flying laying eggs crop.
