概括
雌性 (Drosophila melanogaster) 激素 (Z) -4-undecenal 阻止斑点翼 (Drosophila suzukii) 产卵,并减少对酵母吸引物的吸引力,有助于害虫控制.
科学领域:
- 化学生态化学生态学
- 行为生态学 行为生态学
- 虫害管理 虫害管理 虫害管理
背景情况:
- 斑点翼 (Drosophila suzukii) 和 (D. melanogaster) 在地理上重叠,并争夺水果资源.
- D. melanogaster的存在减少了D. suzukii的产卵,可能是由于幼虫的竞争.
- 费洛蒙调解了昆虫的沟通和生殖隔离.
研究的目的:
- 为了调查D. melanogaster的激素是否影响D. suzukii的卵位行为.
- 为了确定影响D. suzukii产卵和吸引力的特定D. melanogaster激素.
主要方法:
- 双选择卵位测定使用暴露于D. melanogaster.的蓝.
- 用合成的D. melanogaster激素对进行处理: (Z) -4-undecenal (Z4-11Al) 和 (Z) -11-octadecenyl乙酸 (cVA).
- 风洞和田间捕获试验评估了D. suzukii对酵母 (Hanseniaspora uvarum) 的吸引力,有或没有Z4-11Al.
主要成果:
- D. suzukii 在暴露于D. melanogaster的蓝上产卵少得多,而雌性的效果更强.
- 雌性D. melanogaster激素Z4-11Al显著降低了D. suzukii在经过处理的果上的卵位;雄性激素cVA没有影响.
- 在风洞和现场测试中,Z4-11Al显著降低了D. suzukii对发酵酵母的吸引力.
结论:
- 异种类型的激素沟通,特别是D. melanogaster的激素Z4-11Al,有助于D. suzukii和D. melanogaster之间的生殖隔离和资源分割.
- Z4-11Al具有威作用,减少了D. suzukii的卵位和吸引力.
- 在推拉策略中使用Z4-11Al为D. suzukii的综合管理提供了一个新的工具.

The Ratio of X Chromosome to Autosomes
8.4K
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...

In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with distinct numbers of X chromosomes will...
