瓜类实蝇是当前危害葫芦科作物最主要的害虫之一。通过对普通黄板(CK)、实蝇诱杀饵剂黄板(T1)、性信息素黄板(T2)、性信息素诱捕瓶(T3)4种应用较多的绿色防控技术措施进行比较,以期为有效控制瓜类实蝇,保障丝瓜品质和产量提供依据。结果发现,南亚实蝇占诱捕总虫量的98.96%,4种不同诱集方式诱捕到的南亚实蝇均占各自诱捕总虫量98%以上,表明南亚实蝇为当地优势种群,约20 d完成一个世代。结果表明,在4种处理中,诱虫总量T2> CK> T1> T3,表明性信息素黄板诱杀效果最稳定,总体效果最好,在生产实践中推荐应用性信息素黄板诱杀瓜类实蝇。 相似文献

为筛选出对葡萄害虫诱集效果好的粘虫板,选用黄色、蓝色、白色、紫色、绿色、红色、黑色和荧光色8种颜色的粘虫板对葡萄园内昆虫进行诱集试验。结果表明,共诱到昆虫7目18科22种,主要害虫有蓟马、蚜虫和叶蝉,其中蓟马数量占到昆虫总量的88.96%,天敌昆虫主要有寄生蜂、捕食性瓢虫、食蚜蝇和东亚小花蝽。紫板、蓝板和白板对蓟马的诱集效果强,黄板、荧光板和绿板次之,红板和黑板效果差;黄板对蚜虫诱集效果强,绿板和荧光板次之,黄板与其他色板之间差异显著;黄板、荧光板和绿板对叶蝉的诱集效果好,3种色板与蓝板之间差异不显著、与其他色板差异显著。白板、蓝板和黄板诱集到的天敌数量最多,占所有颜色粘虫板诱集天敌总量的69%左右。试验期间诱集到的昆虫益害比为0.036,各色板的益害比依次为黑色>荧光色>绿色>红色>黄色>白色>蓝色>紫色,其中紫板的益害比最低,仅为0.011。结合各色板的诱虫效果和益害比进行综合分析,建议选用紫板对蓟马进行诱杀,适时适量选择性使用黄板对蚜虫、叶蝉等进行诱杀。 相似文献

ABSTRACT The present research investigations were carried out on monitoring the population of bark beetle, Hypocryphalus mangiferae(Stebbing) on mango trees through installation of sticky color traps at different heights of mango tree. The results revealed that maximum monthly mean number of adult beetles (507.91) was recorded on green plastic traps followed by 261.75 beetles on black traps, 215.75 beetles on white traps, 109.83 beetles on red traps, 83.75 beetles on blue traps, and 77.75 beetles on yellow traps. With regards to number of bark beetles on color traps at different heights, the maximum monthly mean number of the beetles (429.83) was recorded at height of 1 above ground level followed by 416.00 beetles at 3′level, 334.08 beetles at 6′and 76.83 beetles at 9′level. The results further revealed that the bark beetle population remained higher from February 2006 to June 2006. The mean temperature for that period ranged between 23.12 to 33.46°C with 48.57 to 76.00% RH. 相似文献

对橘小实蝇在不同寄主上的虫口数量、性比以及不同温湿度条件下蛹期、蛹存活时间、羽化时间、羽化率和成虫寿命等生物学特性作初步研究,同时对橘小实蝇常用诱捕器的设置技巧及常用防治药剂进行筛选。结果表明橘小实蝇在芒果上虫口密度最大,在主要寄主上雌虫数量高于雄虫。在相对湿度控制在83%~86%的条件下,温度为15℃时,蛹期最长30.9 d。蛹在8℃条件下保存时间越短,羽化率越高。成虫羽化高峰时间为12∶00~14∶00时。橘小实蝇在温度恒定为25℃的条件下,相对湿度为83%~86%时,羽化率最高,为89.3%;在湿度恒定为83%~86%的条件下,温度为20℃时的羽化率最高,达到94.1%。在定湿的条件下,温度为25℃时,成虫寿命最长。通过诱捕器和药剂筛选试验可知诱捕器1号、3号和4号对小实蝇有较好的诱捕效果,诱捕器设置间距为20 m、树冠中部、诱剂量2 ml时,诱蝇效果最好。阿维菌素、丁硫克百威、敌百虫,杀虫单、吡虫啉和毒死蜱等有较好的杀蝇效果。 相似文献

通过对生态健康果园(香梨)中利用性信息素和糖醋液诱捕器对梨小食心虫的发生动态进行监测研究,为生态健康果园(香梨)及常规果园的有效监测和适时制定生物防治措施提供参考。研究表明:两种诱捕器对梨小食心虫全年发生消长规律监测的趋势基本一致,梨小食心虫1年发生4代,峰值明显,越冬代羽化高峰期为4月中、下旬。在生态健康果园(香梨)中由于大量、高浓度性信息素的存在,梨小食心虫成虫对糖醋液的趋性比性信息素的趋性敏感,利用糖醋液诱捕器能够很好地监测梨小食心虫的发生动态,且监测准确性明显高于性信息素诱捕器。 相似文献

Animal behavior, cost-based corridor models, and real corridors 总被引:2,自引:1,他引:1
Corridors are popular conservation tools because they are thought to allow animals to safely move between habitat fragments, thereby maintaining landscape connectivity. Nonetheless, few studies show that mammals actually use corridors as predicted. Further, the assumptions underlying corridor models are rarely validated with field data. We categorized corridor use as a behavior, to identify animal-defined corridors, using movement data from fishers (Martes pennanti) tracked near Albany, New York, USA. We then used least-cost path analysis and circuit theory to predict fisher corridors and validated the performance of all three corridor models with data from camera traps. Six of eight fishers tracked used corridors to connect the forest patches that constitute their home ranges, however the locations of these corridors were not well predicted by the two cost-based models, which together identified only 5 of the 23 used corridors. Further, camera trap data suggest the cost-based corridor models performed poorly, often detecting fewer fishers and mammals than nearby habitat cores, whereas camera traps within animal-defined corridors recorded more passes made by fishers, carnivores, and all other non-target mammal groups. Our results suggest that (1) fishers use corridors to connect disjunct habitat fragments, (2) animal movement data can be used to identify corridors at local scales, (3) camera traps are useful tools for testing corridor model predictions, and (4) that corridor models can be improved by incorporating animal behavior data. Given the conservation importance and monetary costs of corridors, improving and validating corridor model predictions is vital. 相似文献
