Tintura roja de cochinilla (ácido carmínico): su papel en la naturaleza
Science (New York, N.Y.)
|May 30, 1980
Resumen
El ácido carmínico disuade a las hormigas, lo que lo sugiere.
Área de la Ciencia:
- Ecología Química Ecología Química.
- Entomología Entomología.
- Comportamiento del insecto Comportamiento del insecto
Sus antecedentes:
- El ácido carmínico, un colorante rojo de Dactylopius spp. (insectos cochinillos), actúa como un disuasorio de la alimentación.
- Esto sugiere que el ácido carmínico puede funcionar como una defensa química contra la depredación en las cochinillas.
Objetivo del estudio:
- Para investigar el papel defensivo del ácido carmínico en los insectos cochinilla.
- Para describir el comportamiento de un depredador no disuadido por el ácido carmínico.
Principales métodos:
- Observación de las interacciones depredador-presa entre los insectos cochinilla y sus depredadores.
- Análisis del comportamiento de una oruga carnívora específica, Laetilia coccidivora.
Principales resultados:
- El ácido carmínico disuade a las hormigas, lo que indica un papel en la defensa de la cochinilla.
- La oruga pirálida, Laetilia coccidivora, es un depredador que se alimenta de las cochinillas.
- Esta oruga no es disuadida por el ácido carmínico y lo secuestra para su propia defensa.
Conclusiones:
- El ácido carmínico sirve como una defensa química para los insectos cochinilla contra la depredación de las hormigas.
- La oruga carnívora Laetilia coccidivora supera el efecto disuasorio del ácido carmínico.
- Laetilia coccidivora utiliza el ácido carmínico ingerido para sus propios fines defensivos, lo que demuestra el secuestro y la reutilización del arma química de una presa.

01:11Aryldiazonium Salts to Azo Dyes: Diazo Coupling
The reaction of weakly electrophilic aryldiazonium (also called arenediazonium) salts with highly activated aromatic compounds leads to the formation of products with an —N=N— link, called an azo linkage. This reaction, presented in Figure 1, is known as diazo coupling and occurs without the loss of the nitrogen atoms of the aryldiazonium salt. Highly activated aromatic compounds such as phenols or arylamines favor the diazo coupling reaction. The coupling generally occurs at the para position.
01:03Fixation and Sectioning
Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

01:23Red Algae
Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
01:26Physical Properties of Amines
Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.
03:02Colors and Magnetism
Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
