| dc.description | The following work carried out represents a contribution to disclose relevant information from research and work carried out on diatoms and their use as insecticides. The climate and the parental material are the main factors that have defined the great diversity of soils in our country Ecuador. Diatoms are fossilized microscopic algae (composed of a transparent silica cell wall and an inner layer of pectin); unicellular composition, shape and varied sizes, coming from fresh or marine waters and with approximately 5,000 known species when the algae die, all the organic content is destroyed, with the exception of its silica skeleton, which will generally be deposited at the bottom of the waters. Diatomaceous earth is a material formed by fossilized algae typical of both marine and fresh waters. Also used as a pH regulator in acidic soils. Diatomaceous earth is a biogenic mineral resource, it has increasing economic importance, it has acquired the complexity of the mineral and its wide spectrum opens up interesting possibilities for the control of pathogens. Soil microorganisms are the most important components of the soil. They constitute its living part and are responsible for the dynamics of transformation and development. Properly milled, the skeletons of diatoms become microscopic, silicon needles that are sharp and harmful to insects. These are harmless to humans and other animals. Animals are free of this effect because their skeleton is located internally, surrounded and enveloped by muscles that support it, and protected by hair or feathers while insects have their armor on the outside and vital fluids are supported and protected by a cover. Waxy, if an object is tiny and sharp, damages its waxy, killing the insect by dehydration, in other families of insects the particles will penetrate internally attacking the respiratory, digestive and reproductive system. | es_ES |

| dc.description.abstract | El siguiente trabajo que se realizó representa una contribución para dar a conocer información relevante de investigaciones y trabajos realizados sobre las diatomeas y su uso como insecticidas. El clima y el material parental son los principales factores que han definido la gran diversidad de suelos en nuestro país Ecuador. Las diatomeas son algas microscópicas fosilizadas (compuestas por una pared celular transparente de sílice y una capa interna de pectina); composición unicelular, forma y tamaños variados, provenientes de aguas dulces o marinas y con aproximadamente 5.000 especies conocidas cuando las algas mueren, todo el contenido orgánico se destruye, con excepción de su esqueleto de sílice, el cual generalmente van a depositarse al fondo de las aguas. La tierra de diatomeas es un material formado por algas fosilizadas propias de aguas tanto marinas como dulces. También usado como regulador de pH en los suelos ácidos La tierra de diatomea es un recurso mineral biogénico, tiene creciente importancia económica, ha adquirido la complejidad del mineral y su amplio espectro abre interesantes posibilidades para el control de patógenos. Los microorganismos del suelo son los componentes más importantes de este. Constituyen su parte viva y son los responsables de la dinámica de transformación y desarrollo. Adecuadamente molidos los esqueletos de las diatomeas se convierten en microscópicas agujas de silicio filosas y dañinas para los insectos, estas son inofensivas para los humanos y otros animales. Los animales están libres de este efecto pues su esqueleto está localizado internamente, rodeado y envuelto por músculos que lo soportan, y protegido por pelos o plumas mientras que los insectos tienen su armadura en el exterior y los fluidos vitales están sostenidos y protegidos por una cubierta cerosa, si un objeto es diminuto y filoso, daña su cerosa, matando al insecto por deshidratación, en otras familias de insectos las partículas penetrarán internamente atacando el sistema respiratorio, digestivo y reproductivo. | es_ES |
