RESULTS It's significant level of the differences of Stilpnotia candida, geometrid, leaves' number between no-light area and light-district area. Jiaduo multi-frequency vibration-killing lamps has a obvious effect to control pests in the tea garden, especially for Stilpnotia candida, geometrid and leaf which has a more prominent role in the booby traps, the difference between lights district with no-lights district is up to a very significant level, But it's limitation to control leafhopper.

The results show that: 27 compounds were identified at 600℃, and most of them were alkenes, alkanes, acids, alcohols and phenolic substances; geraniol was identified, and its relative content was 3.6, which shows that geranyl 8-methoxycoumarin-3-carboxylic acid ester can release a certain amount of geraniol at smoke temperature; geranyl 8-methoxycoumarin-3-carboxylic acid ester can improve and modify the flavor, enhance the notes of sweet aroma and bean aroma, and reduce the biting taste of cigarette smoke.
结果表明,600℃时,8-甲氧基-香豆素-3-甲酸香叶酯的热解产物中共鉴定出27种成分,主要为烯类、烷类、酸类、醇类、酚类;鉴定出香叶醇,且相对峰面积3.6,说明8-甲氧基-香豆素-3-甲酸香叶酯能在卷烟燃吸温度下释放出一定量的香叶醇;8-甲氧基-香豆素-3-甲酸香叶酯具有改善和修饰卷烟香气,增加甜韵和豆香香韵,减轻刺激性的作用。

Mushroom bodies and antennal lobes in Oxycetonia jucunda were conspicuous. Calyces and lobes of the mushroom bodies.were much developed. In contrast, calyces of Ambrostoma quadriimpressum and Henosepilachna vigintioctomaculata were extremely undeveloped. However, the postretinal fibres and circumpharyngeal nerves of Ambrostoma quadriimpressum were highly developed. In the three beetles, 5-HT immunoreactivity was present in all neuropils of the brain and the suboesophageal ganglion. The pattern of 5-HT immunoreactivity and the localization of immunoreactive somata which often clustered into groups were similar among these beetles, while the immunoreactivity intensity was distinct, especially in the lamina.
结果显示,分类地位相近的三种甲虫脑结构大小相差悬殊:小青花金龟脑结构相对发达,蕈形体结构显著,具有发达的冠和叶,嗅叶发达;马铃薯瓢虫和榆紫叶甲的冠极度退化,嗅叶相对不发达;但榆紫叶甲具有十分发达的网膜后纤维和围咽神经。5-HT阳性纤维在三种甲虫的所有神经纤维网中几乎都有分布,且反应模式相似,但各神经纤维网特别是神经节层染色强度差异显著。5-HT阳性胞体有成群分布现象,且在三种甲虫脑中的空间分布位置基本一致。
