摘要
2009~2010年通过田间5点取样对华北一季作区马铃薯病虫害进行普查。结果查得病害有花叶病毒病(表现为花叶症的所有病毒病)、卷叶病毒病、紫顶萎蔫病、早疫病、晚疫病、黑痣病、炭疽病、叶枯病、枯萎病、环腐病、黑胫病、疮痂病共计12种。查得害虫10种:金针虫、蛴螬、地老虎、蚜虫、二十八星瓢虫、芫菁、双斑萤叶甲、草地螟、牧草盲蝽、马铃薯跳甲。明确了上述病虫的分布和为害程度,许多病虫是该地区目前严重威胁生产的问题。
The diseases and pests in the one-crop potato region of North China were surveyed with five-point sampling method during the years of 2009-2010. The disease identified included 1) potato mosaic virus (viruses causing mosaic symptom), 2) potato leafroll virus, 3) potato purple top wilt, 4) potato early blight (Altemaria solaria), 5) potato late blight (Phytophthora infestans), 6) potato canker (Rhizoctonia solan), 7) potato anthracnose (Colletotrichum coccodes), 8) potato macrophomia blight (Macrophomia phaseoli), 9)fusarium wilt (Fusarium spp.), 10) potato dng rot (Corynebacterium sepedonicum), 11) potato black leg (Erwinia spp.), and 12) potato common scab (Streptomyces spp.). The pests were 1) wireworms (Agriotes fuscicollis et al), 2) chafer grubs (Holotrichia spp.), 3) cutworms (Agrotis spp.), 4) aphids (Myzus persicae; Lipaphis erysimi et al), 5) twenty-eight-spotted ladybird (Henosepilachna vigintioc-tomaculata), 6) blister beetle (Epicauta gorhami et al), 7) double-spotted leaf beetle (Monolepta hieroglyphica), 8) beet webworm (Loxostege sticticalis), 9) tomished plant bug (Lygus pratensis), and 10) potato flea beetle (Psylliodes affinis). The distribution and damage of those diseases and pests were demonstrated. Many of them were serious problems in the one-crop potato region of North China now.
