I have never seen a cockroach glow under black light however other pests in more tropical or desert regions, the scorpions, do glow fluorescently. Scorpions are well known for this behavior. Their generally soft cuticle has fluorescent compounds. There is a famous picture on the cover of Science of a fluorescent scorpion. I once took a walk in the evening desert outside Albuquerque NM with a portable black light.

The following colours are UV active (ie. will glow under UV light):- White,Pink,Yellow and Orange. This applies to all product; Beginner, Ultimate performance and the Beaming Poi.

Unfortunately nothing that you would be able to pick up at a local hardware store would work with the T5. The T5 fits in to it's own fixture.

Chemical glow light products are all very similar. Each product is composed of a flexible outer casing typically made of plastic. Inside the casing are a chemical fluid and a fluorescent dye. Also inside the casing, floating in this fluid is a thin walled glass ampoule. The glass ampoule typically contains a hydrogen peroxide solution.

Glesne, Cockroaches are fast enough. They have giant fibers in their ventral nerve cord that transmit the sensory info from their cerci, which sense air currents, directly to their thoracic ganglia which control their leg muscles. This is a reflex circuit which does not need any decision by the cockroach brain. It is fast enough to detect the air wave in front of a predator and allows the cockroach to scuttle away, avoiding capture.

Cockroaches are omnivores, like us. For the most part they will eat anything organic. Mostly they eat dead or immobile things. As indicated elesewhere in the FAQ, they rarely bite a human but might nibble on a sore in the middle of the night when an animal is sleeping. They will eat the glue off the back of postage stamps and the glue bindings off the backs of books, traditional glue being derived from animal protein.

UV (ultra violet) is a portion of the electromagnetic spectrum. UV can not be seen by the human eye, but when it falls on certain materials it may cause them to become fluorescent (ie. glow) and reflect visible light back to our eyes. The following colours are sensitive to UV Light: White, Pink, Yellow and Orange will glow under UV Lighting. Red, Purple, Green, Blue and Black will not glow under UV light.

In our opinion, the brightest glow colors are green and blue followed by yellow, orange, pink and red.

First, remove the glow light stick from its foil packaging. Next, gently bend the glow light stick until the inner glass capsule breaks or "snaps" and the glowing reaction begins. Finally, shake the light stick a few times to mix the chemicals and produce an even glow. For necklaces and bracelets, remove them from their packaging, and then gently bend along their entire length until the chemicals mix and start glowing.

There are four components to most light sticks. The first is the plastic outer casing which holds everything inside. The second is the fluid that you can see moving around in the light stick. The third is the glass tube which floats freely in the fluid. The fourth is the fluid contained inside the glass tube. To make a glow stick 'glow', you only need to bend the outer plastic casing to make the inner glass tube broken.

A: The flourescent bulb must be full spectrum in order to stimulate the chameleon's vitamin D3 requirements. ZooMed's Reptisun 5.0 bulb is well adapted for these purposes.

Yes, take a look at our new fLEDescent product. It requires removing the tubes and ripping out the ballast and uses the zipLED LightSticks on an aluminum plate to provide the light.

No, lets rephrase this. The point color (the muzzle, eye rings, belly) is totally separate from the body color. Black body color is recessive whether or not the points are light are dark. Are dark points recessive or dominant? They are recessive to the white points. the white points are dominant, which is why you see them more often. The donkeys with the dark points (termed no light point) have two recessive genes for the dark points.

Yes. All our chemical glow light sticks and products come in a sealed plastic case. Even if the outer casing of the glow stick is somehow punctured or broken open, the chemical contents are non-toxic and non-flammable. But please never contact the liquid with eyes or ingesting the fluid because irritation will result. There is also the possibility of an allergic reaction. Please keep in mind that under normal use you will never come into contact with the fluid inside the glow light stick.

No, once you have activated a glow light products it will glow until the chemical reaction is finished. You can however prolong the life of your glow light stick or glow light products after it has been activated. Stick it into the freezer. Freezing an activated glow light product will slow the chemical reaction. Once you take it back out of the freezer, the glow light stick or glow light product will start to glow again once it warms up.

Teacher's Guides are available for i-Science textbooks. The Teacher's Guide has a section for each chapter that is a reproduction of the textbook. Teaching material follows the textbook section. Teaching material includes a scheme of work, background information and teaching instructions. If you are buying the Teacher's Guide, it may not be necessary to buy the Textbook. We do not carry the posters or the CD-ROMs referred to in the Teachers' Guides.

Liz, The feet of insects including cockroaches are made up of a brush like pile which reacts with a surface like myriad weak suction cups. The weak forces involve adding together thousands of such individual adhering pillus ends and result in a strong enough force to suspend the body of a fly, a roach or even larger non-insectal critters such as lizards. To step the cockroach must remove the pilli individually in a wave, like ripping off some cellophane or an adhesive bandage.

Cockroaches (and most other insects) have two light receptors, one sensitive in the ultraviolet range and one in the green range. Many insects also have a third light receptor peaking in the blue. Most pest cockroaches are not attracted to light. They are active at night and if anything they might avoid light. However, if you have a patio that is lit you might be asking what type of light should you have in your patio lighting scheme.

Laurie, There is a pest cockroach, Periplaneta australasiae, which is common outdoors in the southern USA. It is commonly called the Australian cockroach. It is found worldwide as a pest and also called the greenhouse cockroach because of its predilection for establishing itself as a pest in the warmth of greenhouses at all latitudes. It is also found in western Australia. I am not sure of the etymology of the common name, 'Australian cockroach'.

http://www.bio.umass.edu/biology/kunkel/rolleston/plate_viii.html ... This is an illustration by GEORGE ROLLESTON published in 1870. Cockroaches shred food with their mouthparts and then swallow it using their salivary glands (e) and salivary reservoir (f) to moisten their food before it enters their crop (d).
