Abstract
Standard pesticides, such as lightweight aluminum phosphide, for instance, can produce hazardous phosphine gas upon disintegration. Due to the fact that no chemicals are utilized in radio-frequency treatment, there are no dangerous contaminants that can be launched into the atmosphere or residues left on the item. Consequently, radio-frequency treatment has no unsafe side effects on customers or the environment.
Purposes
Many insects which impact saved grain are extra immune than those which generally infest fabrics, gallery collections, collections, and furniture. The effectiveness of radio-frequency treatment on these resistant grain bugs would become a guideline. If radio-frequency treatment ruins these insects, then the much less resistant pests have actually satisfied the very same destiny. This eliminates the requirement to collect insects to be sent to an entomologist for identification prior to therapy, a most of time and also expense-consuming exercise.
Recap
Tests were performed at Midwest Freeze-Dry, Ltd. to check out the capacities of using radio-frequency waves for insect pest control. Exposing bugs in a radio-frequency energy area led to one hundred percent kill of the egg, larvae as well as adult phases of kept item insects, which went through testing at the facility. Examinations were carried out on Sitophilus oryza (Rice Weevil), Plodia interpunctella (Indian Meal Moth), and Tribolium castaneum (Red Flour Beetle).
Standards: Pest Option
The three bugs picked for this experiment were chosen because of the problems they develop as well as the difficulties encountered in reliable control in the grain market. The rice weevil (Sitophilus oryza) is the most typical cause of troubles in the storage of raw grains. This weevil is just one of the most challenging to kill due to the fact that it lays its egg inside the grain itself as well as seals it with a waxy plug, making it challenging for fumigants to penetrate.
Plodia interpunctella, the Indian Meal moth causes the largest problems in stored products generally. Not only does it harm the product, however, but the silk webbing which is produced by the caterpillars can also damage machinery. The red flour beetle (Tribolium castaneum) is the second largest cause of issues in the kept item market. Contrasted to the usual bugs which generally infest museum collections, textiles, and furnishings, these insects are challenging opponents.

Products and Approaches
S. oryza, P. interpunctella, and also T. castaneum types were obtained from Pest Limited Incorporated, Indianapolis, Indiana. The eggs, larvae as well as adults (depending upon their phase of advancement) were transferred right into Pyrex Petri recipes (together with their food resource). These examples were taken into the vacuum cleaner chamber sandwiched in between four feet of other material being dealt with by Midwest Freeze-Dry, Ltd.
The vacuum cleaner pressure was pulled to the one-quarter atmosphere. The insects were then exposed to a radio frequency power area for brief pulsations totaling 90 secs of direct exposure. Upon elimination from the chamber all insects had actually been eliminated; (i.e. no indications of life were observed). For independent verification eggs and also larvae were sent to Insects Limited Incorporated to test for any type of further growth or hatching. Insects Limited validated that none happened.
