Requisitos

Conexión Logros para la Investidura: Esta especialidad está relacionada con los requisitos de Logros para la Investidura para ORIENTADOR DE NUEVAS FRONTERAS Estudio de la naturaleza que requiere que requiere (como una de dos opciones) una colección de insectos similar al requisito #1 de esta especialidad. Esta especialidad es una elección popular para la especialidad de la categoría de Estudio de la naturaleza de nivel de destreza 2 o 3 requerido para los ORIENTADORES DE NUEVAS FRONTERAS pero la especialidad de nivel básico es de nivel de destreza 1 entonces no cumple con el requisito.

Realizar una de las siguientes actividades:

1a

Montar una colección de 20 especies de insectos que representen al menos seis diferentes órdenes excluyendo las polillas o mariposas (especímenes montados con descuido no serán aceptables).

i

Colocar bajo cada ejemplar una etiqueta que muestre la localidad donde fue capturado, la fecha cuando fue capturado y el nombre del coleccionista. Las etiquetas no deben ser mayor que 1/4 x 3/4 pulgadas (6 mm x 20 mm).

ii

Identificar los insectos con nombres comunes y género o el nivel de especie en las etiquetas segundas a ser montadas por debajo de la primera.

iii

Organizar todos los especímenes perfectamente en una caja de insectos de acuerdo a las órdenes y familias. Las etiquetas deben ser puestas en la caja y no adjuntadas a los pines de insectos.

1b

Hacer dibujos a color o pinturas de 20 especies de insectos, en la cual se representen por lo menos 6 diferentes órdenes. Dibujos o pinturas deben ser del tamaño real o más grande, para mostrar los detalles de los pequeños insectos y en los colores naturales. Etiquetar los dibujos con nombres comunes y cada género o nombres de la especie en niveles.

1c

Tomar fotos a color de 20 especies de insectos que representen por lo menos seis diferentes órdenes. Todas las imágenes deben estar enfocadas, en primer plano y debidamente etiquetadas, indicando dónde fue fotografiado, fecha de la fotografía, nombres comunes y cada género o nombre del nivel de la especie.

Photographing insects can be challenging, but with a few tips, success is within reach. Perhaps the most important feature of your camera for insect photography is the "macro mode." This feature allows the camera to focus on subjects less than 50cm away. It is often marked on the camera body with a small flower icon (since flower photography is also mostly close-up). If you cannot find how to enable this feature on your camera, consult the user's manual. If you cannot find that, search for one on the Internet.

Once you find an insect, you may discover that it moves far too quickly for you to be able to take a decent picture. One trick you can use in this case is to capture the insect and pop it in a refrigerator for about an hour. This will not harm the insect, but it will certainly slow it down. After taking a few pictures, release the insect into the wild again.

You can also try placing the insect in a drinking glass, and covering the top with the camera lens and body. Use a transparent glass for this so that light can illuminate the insect. Once it settles down, take the picture.

This requirement can really be divided into two phases: field work, and lab work. The field work comes first, and it consists of going out into the wild and finding as many insects as you can. Do not worry about identifying them. Photograph as many as you can. If they are too difficult to photograph, capture them and bring them back to the "lab" where you can refrigerate them as described previously. The "lab work" is when you sit down and attempt to identify the insects you have captured, either photographically, or physically.

We present a crude identification guide below, but if you want to identify the insects you find, you will very likely need a good field guide. You can try various on-line identification aids as well, including Bug Guide.

¿Cuáles son las características distintivas de un insecto?

Insects possess segmented bodies supported by an exoskeleton, a hard outer covering made mostly of chitin. The body is divided into a head, a thorax, and an abdomen. The head supports a pair of sensory antennae, a pair of compound eyes, and mouth parts. The thorax has six legs (one pair per segment) and wings (if present in the species). The abdomen (made up of eleven segments some of which may be reduced or fused) has respiratory, excretory and reproductive structures.

Nombrar cinco especies de insectos perjudiciales y dar detalles sobre cómo controlarlas.

Many insects are considered pests by humans. Insects commonly regarded as pests include those that are parasitic (mosquitoes, lice, bedbugs), transmit diseases (mosquitos, flies), damage structures (termites), or destroy agricultural goods (locusts, weevils). Many entomologists are involved in various forms of pest control, often using insecticides, but more and more relying on methods of biocontrol.

Nombrar cinco especies de insectos beneficiosos.

Although pest insects attract the most attention, many insects are beneficial to the environment and to humans. Some pollinate flowering plants (for example wasps, bees, butterflies, ants). The silkworm has greatly affected human history, as silk-driven trade established relationships between China and the rest of the world. Fly larvae (maggots) were formerly used to treat wounds to prevent or stop gangrene, as they would only consume dead flesh. This treatment is finding modern usage in some hospitals. Adult insects such as crickets, and insect larvae of various kinds are also commonly used as fishing bait.
