Berlese Funnel Lab Report Essay Example Berlese Funnel Lab Report Paper Berlese Funnel Lab Report Paper Antonio Berryless was an Italian entomologist. He worked on pest insects (arthropods), usually those of fruit trees. Arthropods are the most successful animals on the planet. They make up over three. Fourths of all currently known living and fossil organisms. But, many still remained undocumented. Berryless funnels are used for extracting arthropods from soil and litter samples such as our leaf litter. They are supposed to prove that insects that normally live in soil or litter will respond negatively to light. That is why we place the cognomens lamp above the funnels. There are many different ways to make a Berryless funnel and you can also purchase them according to how big you would like them. An alternative to the Berryless funnel is a Hinkler Sack. It is usually made of fabric and can be folded to take up even less space when not in use. They do not require a powered light source because without it the arthropods will still move downwards through the samples and eventually fall into a container of ethanol.
