Ryoichi Takahashi

Ryoichi Takahashi is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ryoichi Takahashi rather than just read about it. In short: Ryoichi Takahashi (高橋良一, Takahashi Ryōichi) (April 6, 1898—July 17, 1963) was a Japanese entomologist. His research focused on hemiptera, including aphids, whiteflies, and scale insects.

Key takeaways

Ryoichi Takahashi belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ryoichi Takahashi to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ryoichi Takahashi from memory before moving on to harder problems.

Reference excerpt

Ryoichi Takahashi (高橋良一, Takahashi Ryōichi) (April 6, 1898—July 17, 1963) was a Japanese entomologist. His research focused on hemiptera, including aphids, whiteflies, and scale insects. He published more than 420 articles. Taxa named after him include:

Takahashilecanium Kondo, 2005 Xenolecanium takahashii Kondo, 2005 Rhachisphora takahashii Martin & Lau, 2011 Melanaphis takahashii Skvarla et al., 2020 Aclerda takahashii Kuwana, 1932 Dicranomyia takahashii Alexander, 1920 Rhyacobates takahashii Esaki, 1923 Ormosia takahashii Alexander, 1919 Aleurotuberculatus takahashii David & Subramaniam, 1976 Aleyrodes takahashii Ossiannilsson, 1966 Rhinopsylla takashii Boselli, 1930 Setaleytodes takahashia Singh, 1933 Isotomurus takahashii (Yosii, 1940) Asterobemisia takahashii Danzig, 1966 Dialeurolonga takahashi David & Jesudasan, 1989 Togepsylla takahashii Kuwayama, 1931

Worked examples

Example 1 — a first encounter with Ryoichi Takahashi

Start with the simplest possible case. Write down what Ryoichi Takahashi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ryoichi Takahashi before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ryoichi Takahashi ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ryoichi Takahashi

In research: Ryoichi Takahashi appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ryoichi Takahashi in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ryoichi Takahashi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1898 births, 1963 deaths, 20th-century Japanese zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Ryoichi Takahashi outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
