Traditional pesticides, such as metal phosphide for instance, can produce dangerous phosphine gas upon decomposition. Because no chemicals are used in radio-frequency treatment there are no dangerous toxins which may be released into the environment or elements left around the merchandise. Therefore, radio-frequency treatment does not have any harmful side effects to consumers, or the environment.

Objectives

Most bugs which affect stored materials are more resilient than these which usually infest textiles, museum collections, libraries collections and furniture. The effectiveness of radio-frequency therapy on these resistant grain insects would become a principle. If radio-frequency treatment destroys these bugs, then your less resistant bugs have fulfilled the same fate. This eliminates the necessity to roll up bugs to be delivered to an entomologist for identification prior to therapy, an usually moment and expense eating exercise.

Conclusion

Assessments were conducted at Midwest Freeze-Dry, Ltd. to analyze the capabilities of using radio-frequency waves for pest pest control. Revealing insects in a radio-frequency power field led to 100 per cent kill of the egg, larvae and adult levels of stored product insects, which underwent screening at the facility. Tests were conducted on Sitophilus oryza (Rice Weevil), Plodia interpunctella (Indian Food Moth), and Tribolium castaneum (Red Flour Beetle).

Criteria: Insect Choice

The three insects are selected for this experiment were chosen as a result of the issues they create and the difficulties experienced in successful control in the feed business. The rice weevil (Sitophilus oryza) is the most frequent cause of difficulties within the storage of uncooked grains. This weevil is among probably the most challenging to eliminate because it lays its egg inside the materials itself and seals it with a wax-like plug, making it difficult for fumigants to penetrate. Plodia interpunctella, the Indian Meal moth causes the greatest issues in stored items overall. Not only does it injury the merchandise, but the silk webbing that is made by the caterpillars can damage equipment. The red flour beetle (Tribolium castaneum) is the 2nd largest cause of difficulties in the saved product business. When compared with the common insects which typically infest museum collections, fabrics and furniture, these insects are difficult adversaries.

Materials and Systems

S. oryza, R. interpunctella and T. castaneum species were obtained from Insects Limited Incorporated, Indiana, Indiana. The ova, larvae and grownups (depending on their stage of development) were transferred into Pyrex petri dishes (along with their food source). These examples were put in the hoover chamber sandwiched between four toes of other materials being handled by Midwest Freeze-Dry, Ltd. The vacuum pressure was taken to one-quarter atmosphere. The insects were then subjected to a radio frequency energy field for short pulsations totaling 90 seconds of coverage. Upon removing from the step all insects had been killed; (i.e. no signs of life were observed). For independent verification eggs and larvae were sent to Bugs Limited Integrated to check for any more development or hatching. Insects Limited verified that none occurred.
