| 1 | 温度对稻虱缨小蜂生态适应性的持续影响显示文摘本文研究了不同温度(22、25、28、31和34℃)对稻飞虱卵期优势寄生蜂稻虱缨小蜂Anagrus nilaparvatae的生态适应性的持续影响。结果表明,28℃和31℃对稻虱缨小蜂的幼期发育、羽化率、成虫寿命和性比的持续影响不明显。22、25和34℃下幼期发育历期随世代增加而延长,羽化率随世代增加而降低。成虫寿命在22℃下随世代增加而延长,34℃下随世代增加而缩短。22℃和25℃下稻虱缨小蜂幼期发育历期有显著的累积效应,34℃下对羽化率的影响有显著的累积效应。 | 刘淑平 郑许松 杨亚军 徐红星 吕仲贤 | 2012 | 中国生物防治学报2012，28，1： | 8 |
| 2 | 田间转Bt基因水稻上稻飞虱卵量、孵化率及天敌作用显示文摘为了评估转基因水稻释放后对非靶标害虫及其天敌的影响,本研究在浙江大学实验农场和中国水稻研究所实验农场2008和2009年连续两年监测了转Bt基因水稻对田间稻飞虱着卵量、卵孵化率、卵被捕食率、卵被寄生率和卵死亡率的影响。结果表明:两年2个调查地点3个水稻品系(克螟稻1、克螟稻2和秀水11)上的稻飞虱平均每分蘖着卵量、卵孵化率、卵被捕食率和卵被寄生率的趋势基本一致,而且田间3个水稻品系上稻飞虱卵量的高峰期均持续2周左右;但是两年2个调查地点3个水稻品系上稻飞虱卵死亡率则没有一致的趋势。此外,总体上3个水稻品系上稻飞虱平均每分蘖着卵量、卵孵化率、卵被捕食率、卵被寄生率和卵死亡率差异均不显著(P>0.05)。因此,稻田中转Bt基因水稻对稻飞虱卵没有显著的影响。 | 高明清 侯守鹏 蒲德强 时敏 叶恭银 彭于发 陈学新 | 2011 | 昆虫学报2011，54，4： | 7 |
| 3 | 稻虱缨小蜂耐热品系的生物和生态学特征显示文摘稻虱缨小蜂Anagrus nilaparvatae Pang et Wang是控制稻飞虱种群暴发的主要寄生性天敌之一,高温是制约其种群动态的重要因子。为了解35℃高温驯化获得的稻虱缨小蜂耐热品系(NR品系)的生防潜力,对不同温度下该品系的发育历期、有效积温、寄主卵选择、产卵量以及极端高温胁迫参数进行了测定。结果发现,与未经高温驯化的稻虱缨小蜂品系(HZ品系)相比,20℃时,NR品系雄蜂的发育速率显著高于HZ品系,这一差异主要表现在卵-幼虫中期和蛹期的发育时间明显缩短。NR品系在高温下能维持正常的产卵能力,35℃下NR品系产卵量仍能达到18.80粒/雌。NR品系有更强的耐极端温度的能力,50℃下NR品系雄蜂的热击倒时间为15.19 min,比HZ品系雄蜂长3.03 min。补充不同营养对NR品系的产卵量存在影响,35℃条件下补充10%蔗糖既能延长其寿命,也能提高产卵量。以上研究结果表明高温驯化得到的稻虱缨小蜂品系在35℃高温环境中能维持正常的生长发育和寄生能力,具备适应稻田夏季高温环境的潜力。 | 王冰洋 黄庭发 马莹 汤冰洁 周强 张古忍 | 2021 | 中国生物防治学报2021，37，4： | 2 |
| 4 | Influence of Temperature on Symbiotic Bacterium Composition in Successive Generations of Egg Parasitoid, Anagrus nilaparvatae显示文摘Anagrus nilaparvatae is the dominant egg parasitoid of rice planthoppers and plays an important role in biological control. Symbiotic bacteria can significantly influence the development, survival, reproduction and population differentiation of their hosts. To study the influence of temperature on symbiotic bacterial composition in the successive generations of A. nilaparvatae, A. nilaparvatae were raised under different constant temperatures of 22 °C, 25 °C, 28 °C, 31 °C and 34 °C. Polymerase chain reaction-denaturing gradient gel electrophoresis was used to investigate the diversity of symbiotic bacteria. Our results revealed that the endophytic bacteria of A. nilaparvatae were Pantoea sp., Pseudomonas sp. and some uncultured bacteria. The bacterial community composition in A. nilaparvatae significantly varied among different temperatures and generations, which might be partially caused by temperature, feeding behavior and the physical changes of hosts. However, the analysis of wsp gene showed that the Wolbachia in A. nilaparvatae belonged to group A, sub-group Mors and sub-group Dro. Sub-group Mors was absolutely dominant, and this Wolbachia composition remained stable in different temperatures and generations, except for the 3rd generation under 34 °C during which sub-group Dro became the dominant Wolbachia. The above results suggest that the continuous high temperature of 34 °C can influence the Wolbachia community composition in A. nilaparvatae. | WANG Xin XU Hong-xing LIU Shu-ping TANG Jiang-wu ZHENG Xu-song LV Zhong-xian | 2016 | Rice science2016，23，4： | 1 |
