概括

这项研究确定了Euxesta果的关键视觉和嗅觉吸引力,Euxesta果是玉米种植的关键害虫. 结果将有助于开发有效的监测陷,用于综合性害虫防治战略.

科学领域:

农业昆虫学农业昆虫学
虫害管理虫害管理虫害管理
昆虫的行为昆虫的行为

背景情况:

玉米种植面临来自Euxesta属 (Diptera:Ulidiidae) 的新害虫挑战,特别是阿根廷的Euxesta eluta和Euxesta mazorca.
以前对Euxesta物种的控制方法是不够的,目前还没有生物合理的策略.
这些害虫的出现与Bt玉米和较柔软的角玉米品种有关,增加了它们的影响.

研究的目的:

为了研究吸引Euxesta物种的视觉和嗅觉刺激.
为开发有效的Euxesta sp.监测陷提供基础数据.
探索在玉米中对Euxesta害虫的潜在生物控制策略.

主要方法:

进行了实验室和实地实验,以评估对视觉线索 (颜色,形状,尺寸,对比度) 的反应.
嗅觉响应被评估使用完整的相比类虫受损的玉米耳朵在嗅觉仪.
实地试验比较了各种诱的疗效,包括托鲁拉酵母和化蛋白与.

主要成果:

成熟的Euxesta被蓝色,矩形和大型陷显著吸引,对比度没有显著的影响.
与完整的耳朵相比,受Lepidopteran损害的玉米耳朵吸引了更多的Euxesta后代.
用氧和托鲁拉酵母水解蛋白质产生了最高的陷捕获量,捕获的雌性比例更高.

结论:

颜色和形状等视觉线索,以及受损玉米的嗅觉刺激,对Euxesta sp.至关重要. 吸引力. 吸引力.
开发的见解对于创建有效的Euxesta害虫监测工具至关重要.
将这些发现应用于基于陷的管理,可以为可持续的玉米生产做出贡献.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Taste Buds and Receptors

Taste Buds and Receptors

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
