概括

交配会影响果的宿主标记行为和产卵. 男性的精液,尤其是无菌的精液,会改变雌性对宿主标记和费洛蒙沉积的投资,影响生殖策略.

科学领域:

昆虫学昆虫学是一门学科.
行为生态学行为生态学
化学生态化学生态学

背景情况:

交配和精液转移影响昆虫的卵位和宿主标记行为.
男性辅助腺 (MAG) 蛋白质是交配期间转移的关键组成部分.
宿主标记性激素 (HMP) 阻止同种和异种的卵置,减少幼虫的竞争.

研究的目的:

研究雌性交配状态,精液接收和雄性状况如何影响*Anastrepha ludens*中的卵位和宿主标记行为 (HMB).
从交配和未交配的雌性中确定HMP的疗效.
检查野生和无菌雄性之间MAG大小和蛋白质转移的差异.

主要方法:

对雌性交配状态 (交配/不交配) 和雄性类型 (野生/无菌) 的实验性操纵.
量化排卵率和花在宿主标记上的时间.
对野生与无菌雄性中MAG大小和蛋白质含量的分析.

主要成果:

接受精液增加了产卵和宿主标记的时间.
未交配的雌性产卵较少,但与交配的雌性一样有效地标记宿主.
雌性与无菌雄性交配的雌性花费了更少的时间来标记宿主,尽管产卵率相似.
绝育的雄性表现出更大的MAG,并比野生雄性转移更多的蛋白质.

结论:

精液成分,特别是蛋白质,可以操纵雌性宿主标记行为和生殖投资.
女性似乎评估男性的状况,相应地调整HMB.
男性的状况影响精液的组成和转移,这对女性的行为和母亲的投资有影响.

The Ratio of X Chromosome to Autosomes

The Ratio of X Chromosome to Autosomes

In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Mate Choice

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
