“小黄蛉”是我国长江下游流域的一种蟋蟀科昆虫,它因为擅长鸣叫得到虫友的喜爱,其中鸣声最优美的被称为“黄金蛉”。但是,小黄蛉的寿命只有三四个月,而且大多在秋季产卵,需到转年夏季才孵化繁殖,这对于鸣虫爱好者来讲,赏玩的季节性和局限性都比较突出。产自南方的野生小黄蛉,能在北方无季节限制地人工繁殖成活吗?带着这样的疑问,我制定了两套实验方案。一、材料的准备与实验步骤方案一模拟南方野生环境1.准备一个长40厘米、宽20厘米、高25厘米的玻璃鱼缸,顶部封闭,留直径为10厘米
Small yellow creek is a cricket family insects in the lower reaches of the Yangtze River in our country. Because it is good at tweeting, it gets the love of insects, the most beautiful of which is called “gold 蛉”. However, the longevity of small yellow cicadas only three or four months, and most of the spawning in the fall, the need to turn summer incubation hatch, which for songbird lovers, seasonal and limitations of the play are more prominent. With the quarantine of wild yellowish-yellow cantharides from the south, can artificial breeding survive in the north without seasonal restraints? With these questions, I developed two sets of experimental programs. First, the preparation of materials and experimental steps Scenario 1 to simulate the wild environment of the South 1. Prepare a 40 cm long, 20 cm wide, 25 cm high glass fish tank, closed at the top, leaving a diameter of 10 cm
