Host-plant volatiles play an important role as cues for herbivores in search of resources, mates and oviposition sites in complex environments. plant volatile-based attractants can be developed for pest monitoring and control. Previously, we indicated that mated female adults of Callosobruchus chinensis showed choice preference behavior toward 2-hexenal and benzaldehyde. Our objective here was to investigate the synergistic effect of host-derived attractive volatiles in attracting C. chinensis under laboratory and field conditions in Shanxi Province, China. We hypothesized that the ratio and concentration of volatiles derived from Vigna radiata play critical roles for C. chinensis in locating this host. Therefore, we collected and identified the volatiles of mungbean by using headspace collection and GC-MS. The effectiveness of different ratios and concentrations of two compounds (2-hexenal and benzaldehyde) that elicit C. chinensis searching behavior were examined in Y-tube olfactometer assays. The combination of 300 μg μL^–1 2-hexenal and 180 μg μL^–1 benzaldehyde loadings exhibited a synergistic effect on attracting C. chinensis (82.35%). Compared to control traps, the adults were significantly attracted to traps baited with blends, and more attraction to females than males was found for blend traps in the field experiments. Our results suggest that blends of this specific concentration and ratio of benzaldehyde and 2-hexenal can be used in traps as attractants for C. chinensis monitoring and control in the field.

[Objective] The paper was to study the slow release effects of eight common kinds of slow release solvents on n-hexane, and to provide a reference for the construction of slow release system of attractants or repellents synthesized by plant volatiles. [Method] The effect of slow release solvents on volatile quantity and release rate of n-hexane was compared by weight loss method. [Result] Under indoor natural conditions [(22±2) ℃,RH 50%±10%], the slow release effect of lubricating oil on n-hexane was the best, followed by liquid paraffin. The best ratio of slow release solvent(lubricating oil and liquid paraffin) and n-hexane was 5∶1 and the best mixing time was 3 h, which improved the slow release effects of n-hexane by6.3 and 4.7 times, and prolonged the half-life of n-hexane by 1.3 and 1.0 times, respectively. Slow release solvents mainly affected the post-half-life period of n-hexane, and the release rates of n-hexane mixed with lubricating oil and liquid paraffin were decreased by 10.4 and 7.7 times, respec-tively. During the half-life period, the release rates of n-hexane were decreased by 1.3 and 1.0 times, respectively. [Conclusion] Two kinds of slow release solvents with good slow release effect on volatile n-hexane are screened out, and the proportion and mixing time of slow release solvent and volatile are determined, which will provide technical support for the construction of plant volatile slow release system.

本文利用昆虫触角电位技术记录了棉平突蚜茧峰Lysiphlebia japonica(Ashmead)(Hymenoptera:Aphidiidae)对棉花挥发性次生物质(标样和提取物)和棉蚜信息素(性信息素和报警激素)的触角电位反应,没有发现雌雄间触角电位对差异(P>0.05)。所有测试标样中,活性最强的化合物是庚醇、己醛、庚醛、苯甲醛和饱合的六碳到九碳的直链正醇;雌雄蚜茧蜂都对绿叶气味物质反应强烈,而萜烯类化合物引起的触角电位反应相对较弱,在所有测试的萜烯类物质中,只有香叶醇表现出较强的活性;棉蚜茧蜂对棉蚜信息素的反应较为强烈,而对四种植物提取物,以棉花提取物活性最强,黄瓜次之,丝瓜和南瓜之间没有明显差别而且反应最弱。浓度反应曲线表明绿叶气味物质的反应域值比萜烯类物质低。根据以上结果,我们得出如下结论:绿叶气味物质可能是寄生蜂寻找寄主的远距离化学线索,而大多数萜烯类则在近距离内发挥作用;棉蚜信息素可能是很强的引诱剂,能够吸引寄生蜂而使其更容易找到寄主;羽化前经历对成虫触角的反应敏感性有一定影响。

用触角电位法研究了大豆蚜、棉蚜和桃蚜对39种挥发性次生化合物的反应,结果如下:1)绿叶气味化合物及其异构体的去极化电压远强于萜烯类;具有6个碳原子的醇类和醛类是最有活性的化合物.2)大豆蚜和棉蚜对醛类和脂类的反应要比对相应的醇类强,这与桃蚜的实验结果刚好相反.3)蚜虫嗅觉系统所显示的活性与刺激化合物的结构有关,醇类和醛类刺激所引起的EAG饱和的要比不饱和的强.4)大豆春迁蚜对萜烯衍生物(醇、醛、脂)的触角电位反应高于棉蚜,而对萜烃化合物的反应刚好相反.5)各种化合物引起的EAG峰形不同;牛儿醇、癸醇和香茅醇刺激所引起的波形回复最慢,而在直链饱和醇中随着碳原子数的增加而回复速度减慢.

Volatilomics is essential for understanding the biological functions and fragrance contributions of plant ***,the annotation coverage achieved using current untargeted and widely targeted volatomics(WTV)methods has been limited by low sensitivity and/or low acquisition ***,we introduce WTV 2.0,which enabled the construction of a high-coverage library containing 2111 plant volatiles,and report the development of a comprehensive selective ion monitoring(cSIM)acquisition method,including the selection of characteristic qualitative ions with the minimal ion number for each compound and an optimized segmentation method,that can acquire the smallest but sufficient number of ions for most plant volatiles,as well as the automatic qualitative and semi-quantitative analysis of cSIM ***,the library and acquisition method we developed can be self-expanded by incorporating compounds not present in the library,utilizing the obtained cSIM *** showed that WTV 2.0 increases the median signal-to-noise ratio by 7.6-fold compared with the untargeted method,doubled the annotation coverage compared with the untargeted and WTV 1.0 methods in tomato fruit,and led to the discovery of menthofuran as a novel flavor compound in passion *** 2.0 is a Python library with a user-friendly interface and is applicable to profiling of volatiles and primary metabolites in any species.
