The process of pinning insect specimens is a dry method to preserve and display collections and requires special entomological equipment to accomplish effectively. [1] It is used primarily for hard-bodied, medium to large specimens and is beneficial for easier study and color preservation.
It is not exactly known how long dry plant specimens last in storage, but with proper conservation, they have been able to last many centuries. Specimens collected by Linnaeus in the eighteenth century and by Banks and Solander on the Endeavour voyage in 1788 are still excellently preserved. [4] The specimens may be whole plants or plant parts.
Bird and mammal specimens are conserved as dry study skins, a form of taxidermy. [1] The skin is removed from the animal's carcass, treated with absorbents, and filled with cotton or polyester batting (In the past plant fibres or sawdust were used). Bird specimens have a long, thin, wooden dowel wrapped in batting at their center.
A Berlese funnel or Berlese trap is a device used to extract desiccation-intolerant invertebrates from samples of soil or leaf litter. It works by creating a desiccation gradient over the sample such that mobile organisms will move away from the dry environment and fall into a collecting vessel, where they are preserved for examination.
Plant collecting is the acquisition of plant specimens for the purposes of research, cultivation, or as a hobby. Plant specimens may be kept alive, but are more commonly dried and pressed to preserve the quality of the specimen. Plant collecting is an ancient practice with records of a Chinese botanist collecting roses over 5000 years ago. [1]
The specimens represent approximately 60% of the known insect families, with especially strong collections of butterflies and moths, flies, mosquitoes, beetles, and wasps. The majority of the collection is pinned or point-mounted and stored dry in drawers, but there are also many specimens housed in alcohol, on slides, and in envelopes.
Beetle collection at the Melbourne Museum, Australia. Insect collecting refers to the collection of insects and other arthropods for scientific study or as a hobby. [1] Most insects are small and the majority cannot be identified without the examination of minute morphological characters, so entomologists often make and maintain insect collections.
Hydrogen peroxide can be mixed with water and used to kill fungus gnat larvae in infected soil with a mixture of one part 3% hydrogen peroxide mixed with four parts water, then applied to the soil. [ 5 ] [ 6 ] Adults can be trapped with sticky traps made of yellow card stock or heavy paper coated in an adhesive since the adults are attracted to ...
