概括

此摘要是机器生成的。

幼虫,而不是身体, 吸引寄生虫像微型炎媒介. 主要的吸引物是乙烯棕酸, 这是一种消化过程中产生的化合物,

科学领域

化学生态学
昆虫的行为
微生物共生

背景情况

自然敌人使用嗅觉线索来定位宿主.
昆虫幼虫的吸引物,特别是,还不太清楚.
使用了一般性夜 Helicoverpa armigera 和 Spodoptera frugiperda.

研究的目的

鉴定虫幼虫对内寄生虫微型炎媒介的吸引物.
确定幼虫体或是否更有吸引力.
研究这些有吸引力的化合物的起源和性质.

主要方法

用M.中间体雌性进行行为测试.
电生理学测量
分析不同饮食的和幼虫体提取物.
通过抗生素操纵饮食.

主要成果

幼虫对M.介质的吸引力明显高于幼虫体.
易挥发性化合物乙基棕酸被确定为弗拉斯的主要吸引剂.
抗生素治疗降低了乙基棕酸盐的产生和的吸引力,
吸引力是独立于宿主植物物种.

结论

幼虫体比幼虫体更重要的是M.介质宿主位置.
乙烯棕酸是一种微生物依赖的消化副产品,是frass的主要吸引剂.
这一发现对理解昆虫-微生物-寄生虫相互作用和制定害虫管理策略有意义.

Osmoregulation in Insects

Osmoregulation in Insects

Malpighian tubules are specialized structures found in the digestive systems of many arthropods, including most insects, that handle excretion and osmoregulation. The tubules are typically arranged in pairs and have a convoluted structure that increases their surface area.

Malpighian tubules extend from the digestive tract, typically the area between the midgut and hindgut, into the hemolymph—a mixture of blood and interstitial fluid found in insects and other arthropods, as well as most...
