Chemical identification of ODPs from extracts of larval frass,egg masses and midgutThe major ODPs of the extracts from larval frass,egg masses and midguts of O.furnacalis and O. nubilalis fed on an artificial diet were identified by GC and GC-MS.

玉米螟幼虫粪便、卵块及中肠提取液中产卵忌避信息素成分鉴定采用GC和GC-MS方法测定了两种玉米螟取食人工饲料后幼虫粪便、卵块，以及人工饲料和幼虫中肠提取液中的主要化学成分。

The difference between the test groups and the control group was statistically significant. It could be deduced that all the insecticides tested in this experiment damaged the spiders′ intestinal mucosa, compromising its function as a barrier and letting large molecules such as FTIC-D more easily penetrate. Among the insecticides, pyrethrin and Bt preparation are bio-insecticides, and the FITC-D concentrations of the spiders exposed to these two bio-insecticides were more than those of the spiders exposed to the chemical insecticides imidacloprid and dipterex. The difference between the bio-insecticide groups and the imidacloprid group was significant, but there was no significant difference between the bio-insecticide groups and the dipterex group.

结果表明：4种杀虫剂处理后拟环纹豹蛛血液中的荧光素浓度远高于对照组，各个处理组拟环纹豹蛛血液样本中的荧光素浓度均与对照组存在极显著差异，可见4种杀虫剂均将对拟环纹豹蛛肠黏膜的屏障功能造成损伤，导致大分子物质易于通过；其中1.5%除虫菊素水乳剂三保奇花和Bt制剂强杀处理后拟环纹豹蛛中肠黏膜的通透性高于仿烟碱类化学杀虫剂吡虫啉处理组，差异达到显著水平，但与有机磷杀虫剂敌百虫处理组差异不显著。

Las multiplied again in the hemocoel and then invaded other host tissues, including hemocytes, nervous tissue, fat body, trachea, and muscle. Eventually, Las invaded the salivary gland and the Las-infected psyllids were enabled to transmit Las to other host plants. Symptoms of serious pathogenesis occurred in the muscle tissue.

黄龙病菌必需先穿过中肠上皮细胞并於中肠细胞内进行增殖，接著进入血腔继续进行增殖，并逐渐移行至其他组织包括血球、神经、脂肪体、气管上皮细胞及肌肉等，最后抵达唾腺，届时柑橘木虱即具有传播黄龙病的能力。

Monodon severely infected by MBV was different from those of healthy ones. The contents of fatty acids in mid-gut glands of P. japonicus suffering from BMNV diseases also displayed similar changes.

MBV重度感染斑节对虾中肠腺各种脂肪酸的含量均有异于健康虾，患病日本对虾中肠腺各种脂肪酸的含量也出现明显的变化。

The stomach was expanded and Y-shaped and many goblet cells were observed in the epitheliums of cardiac stomach and pyloric stomach.

幽门盲囊发达，肠短但分3部分：前肠、中肠和后肠，肠道系数为0.43，肠道由前向后杯状细胞和粘膜皱褶不断减少。

Result The optimum reaction temperature in stomach, pyloric caecas, foregut, mid-intestine, hindgut and liver were 40-45, 40, 35-40, 40, 40 and 40℃ resp. for protease, 40, 30, 30, 30, 40 and 30℃ for amylase, 40, 40, 35-40, 40, 40 and 25℃ for lipase.

结果］胃、幽门垂、前肠、中肠、后肠、肝胰脏内，蛋白酶最适反应温度分别为40~45、40、35~40、40、40、40℃；淀粉酶的最适反应温度分别为40、30、30、30、40、30℃；脂肪酶最适反应温度分别为40、40、35~40、40、40、25℃。

The results showed that the digestibility and enzymolysis rate were in the order of foregut, midgut, hepatopancreas, hindgut and stomach.

结果显示：离体状态下兰州鲇消化道各部位的消化能力和酶解能力依次为前肠、中肠、肝胰脏、后肠和胃。

The activities of amylase from high to low were pancreas, the midgut, the hindgut, the foregut, the stomach and the esophagus, respectively.

脂肪酶活力大小顺序依次为胰脏＞后肠＞中肠＞前肠＞胃＞食道，胃、肠和胰脏脂肪酶的最适pH值分别为2.2、7.4和8.0，最适温度均为50℃。

Furthermore, allatostatins inhibit contraction of muscles in heart, dorsal vessel and oviducts.

AS能抑制前肠、中肠、后肠肌肉的收缩，导致昆虫厌食、生长延迟、死亡率上升等现象，此外，还能抑制心脏、背血管和输卵管等器官中肌肉的收缩。

This difference was that this kind of pigment in the female could not penetrate through the midgut effectively, compared to the male, but accumulated in the midgut.

而这种差别是由于与雄性相比雌性中肠不能有效地透过该种色素，而是富集于中肠中。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
