Bactrocera bryoniae and Bactrocera neohumeralis are highly destructive and major biosecurity/quarantine pests of fruit and vegetable in the tropical and subtropical regions in the South Pacific and Australia. Although these pests have not established in China, precautions must be taken due to their highly destructive nature. Thus, we predicted the potential geographic distribution of B. bryoniae and B. neohumeralis across the world and in particular China by ecological niche modeling of the Maximum Entropy(Max Ent) model with the occurrence records of these two species. Bactrocera bryoniae and B. neohumeralis exhibit similar potential geographic distribution ranges across the world and in China, and each species was predicted to be able to distribute to over 20% of the globe. Globally, the potential geographic distribution ranges for these two fruit fly species included southern Asia, the central and the southeast coast of Africa, southern North America, northern and central South America, and Australia. While within China, most of the southern Yangtze River area was found suitable for these species. Notably, southern China was considered to have the highest risk of B. bryoniae and B. neohumeralis invasions. Our study identifies the regions at high risk for potential establishment of B. bryoniae and B. neohumeralis in the world and in particular China, and informs the development of inspection and biosecurity/quarantine measures to prevent and control their invasions.  相似文献

Pheromone-based communication disruption ofAdoxophyes orana on peach using the new RAK 3+4 dispensers and their effect on development of fruit rot diseases     

E. Navrozidis  T. Thomidis  T. Sipouridis  I. Xatzicharisis  I. Fotiadis  D. Servis 《Phytoparasitica》2005,33(2):149-153

The effectiveness of the pheromone-based communication disruption method was examined against the summerfruit tortrix,Adoxophyes orana F.v.R. (Lepidoptera: Tortricidae), a pest of peach trees, using the new RAK 3+4 dispenser (BASF). NoA. orana males were captured in pheromone traps inside the experimental orchards, which were saturated with the RAK 3+4 dispensers. The percent of damaged leaves was practically zero, while the level of damaged fruits was 0–6% in pheromone-treated orchards. The percentage of fruit rot caused byMonilinia laxa was lower in pheromone-based communication disruption orchards than in the control. It was concluded that the RAK 3+4 dispenser could be used againstA. orana as an economical and environmentally friendly method.  相似文献

杨友兰  王红武  王全寿  曹琳  梁定栋  张志勇 《中国生物防治》2002,18(3):124-127

对山西菜田捕食性食蚜蝇优势种及对菜蚜的控制效果进行了研究，菜田常见捕食性食蚜蝇有黑带食蚜蝇，大灰食蚜蝇，斜斑鼓额食蚜蝇，野食蚜蝇，四条小食蚜蝇，短翅细腹食蚜蝇6种，以黑带食蚜蝇种群数量最大，平均占全年发生总量的36.3%，通过对食蚜蝇产卵量，卵化率，幼虫期捕食量和羽化率测试，筛选出的黑带食蚜蝇，大灰食蚜蝇，斜斑鼓额食蚜蝇幼虫对菜蚜均有较强的捕食能力，其中黑带食蚜蝇为山西菜田菜蚜捕食性食蚜蝇优势种，用黑带食蚜蝇三龄幼虫对菜蚜进行防治试验，结果以1：180防效最佳，72h后控制效果达93.5%。  相似文献   

棉铃虫性诱剂诱捕器的改进及其应用研究     

刘定忠  王荣龙  余昌喜 《中国植保导刊》2002,22(7):8-10

利用废弃的食用油油壶制成棉铃虫诱捕器,可提高诱蛾的效果。挡板距诱捕器器口的距离以3cm的效果最佳。与常规水钵、水盆诱捕器相比较,全年诱蛾总量分别增加116.3％和减少79.8％,但诱蛾灵敏度均高出18.72％。  相似文献

试验结果表明:在17～31℃恒温范围内,稻茎毛眼水蝇的发育速率随温度上升呈逻辑斯蒂曲线趋势。幼虫、蛹存活率、成虫产卵量、种群增长指数随温度的上升呈抛物线趋势。卵孵化率在20～31℃范围内无显著差异,均在92％以上。在17℃和35℃时,孵化率下降至86.67％和76.36％。在35℃时,幼虫不能存活,成虫不产卵。  相似文献

模毒蛾Lymantria monacha是内蒙古大兴安岭林区重大森林害虫。通过对模毒蛾性信息素诱捕器应用技术的研究显示:不同类型的诱捕器诱虫效果不同,圆筒型和船型诱捕器的诱捕效果较好,方形的较差;诱捕器设置高度对诱虫效果的影响不同,设置在树冠下层和中层的诱捕器诱捕效果较好,上层的较差;不同设置距离的诱捕器的诱虫效果不同,随着设置距离的增加,诱捕器的诱捕量逐渐下降,设置于距林缘50 m的诱捕器诱虫效果最好,性信息素诱捕器的最远引诱距离可能为280 m。研究结果为利用性信息素对模毒蛾进行种群监测和防治提供了依据。  相似文献

为明确山西省太谷地区‘壶瓶枣’枣园绿盲蝽越冬卵分布及粘虫板对绿盲蝽产卵的影响,对该地区不同管理水平的枣园绿盲蝽越冬场所进行调查,并结合室内外饲养观察卵孵化规律,在枣园悬挂黄色粘虫板观察其对绿盲蝽秋季成虫落卵量的影响。结果表明:不同管理水平枣园,绿盲蝽越冬卵分布场所均以枣树断茬口为主,其次是修剪口和中年生枣股,一年生枣股、老年生枣股及翘皮缝也有少量分布;枣园内外的杂草上均发现有少量绿盲蝽越冬卵,而在土壤中几乎没有分布;枣树不同部位卵分布的集中程度不同,卵粒数由多到少顺序为:断茬口枣股修剪口翘皮缝;绿盲蝽越冬卵4月中下旬开始孵化,孵化盛期为4月底到5月初;秋末,挂黄色粘虫板可使绿盲蝽越冬卵数量降低42.88%～87.56%。研究结果对‘壶瓶枣’枣园绿盲蝽的防控具有重要指导意义。  相似文献

闫征远  范洁茹  刘伟  周益林 《植物病理学报》2017,47(2):253-261

2014和2015两年度利用Burkard定容式孢子捕捉器监测了高感小麦白粉病品种京双16种植区和中感品种众麦2号种植区田间空气中的病菌孢子浓度变化动态,同时利用小型气象站监测了田间的气象因子,通过分析京双16和众麦2号种植区空气中孢子浓度与空气温度、湿度、降雨、风速和太阳辐射率的相关性,发现空气中的孢子浓度主要与空气温度呈显著的正相关性(r0.348 3,P0.05)。在此基础上,分别分析了田间病情与调查日期前累积孢子浓度、一周前累积孢子浓度、前一周累积孢子浓度和当周累积孢子浓度的关系,结果表明,中感品种众麦2号田间病情与累积孢子浓度的关系均呈指数关系,其中田间病情与调查日期前累积孢子浓度或一周前累积孢子浓度的拟合效果最好,而感病品种京双16的田间病情与累积孢子浓度多呈对数关系,其中病情指数与一周前累积孢子浓度的拟合效果最好。  相似文献
