Insect-proofing

As a residue-free physical treatment, irradiation does not provide any protection from insects that might reinfest the product after postirradiation storage. Therefore it is of paramount importance that proper care is needed to store, transport, and market irradiated products in insect-proof containers or packages [34]. 

Use Leather dressing, polishes, cements, varnishes, candles, electric insulating composition, sealing wax, waterproofing and insect-proofing containers, paint removers, dentistry, paper sizes, stiffener for soft waxes. 

Use Condenser impregnation, moisture-, flame-, acid-, insect-proofing of wood, fabric, and other... 

With most use patterns the photoinstability of PBO described in the previous pages is a distinct advantage in reducing the residues remaining in the environment. However, certain uses, such as the insect proofing of timber, require both the insecticide and the synergist to be as persistent as possible in light. 

Walls, floors, and ceilings of the facility are constructed to form a sealed internal shell which facilitates decontamination and is animal and insect proof. The internal surfaces of this shell are resistant to liquids and chemicals, thus facilitating cleaning and decontaminationofthe area. Allpenetraions in these structures and surfaces are sealed. Internal facdity appurtenances, such as light fixtures, air ducts, and utility pipes, are arranged to minimize horizontal surface areas on which dust can settle.

Candelilla wax n. Natural wax obtained from the stems of a plant, which grows in Mexico and Texas. It varies in color from pale yellow-to-yellow or greenish-brown. It is one of the harder waxes, although not so hard as carnauba wax. Used in varnishes, electric insulation compositions, waterproofing and insect proofing, and paint removers. 

We have found that a ratio of field time to classroom time of 1 2 was best for learning identification. We found it useful to leave as early as possible in the morning and look at plants in situ, and then collect specimens in field presses and in plastic bags for examination back at the classroom. We left all the literature behind when going into the field. We used field stations with concrete floors, insect-proof buildings and electric lights the educational experience is far greater in comfortable conditions.
