Abstract
The research aimed to propose a non-destructive technology to control subterranean termites Coptotermes curvignathus Holmgren infestation based on electromagnetic waves. A portable apparatus for this technology has been built and its experiment is presented in this paper. Some electrical parameters were measured and analyzed along with their effects to the termites. The experiment using frequency range between 30 Hz - 600 kHz has been done. The average error of the apparatus by comparing the result with the direct measurement using oscilloscope was also measured. The highest error value appeared at 600 kHz with frequency error 6.05 kHz. The highest error of voltage (i.e. 0.186 Volt) appeared at 100 kHz. For safetiness, the highest magnetic field at 300 kHz was 0.1815 μT and at 500 kHz was 0.00725 μT which were safe for human. The average value of termites mortality was higher on irradiation time 120 minutes than 60 minutes respectively in all test frequency: 300 kHz, 400 kHz, 500 kHz and 600 kHz. This paper presents an important information of the electromagnatic-based technology for environmental friendly termites control in spite of using the insecticides.
Highlights
Nowadays, termites are known as a group of serious pests in the world
The maximum voltage set in the TCA was 20 Volt, while in the higher frequency it tended non-linearly to operate with lower frequency
This is caused by the requirement of current for some frequency groups become higher than the lower frequency groups
Summary
Termites are known as a group of serious pests in the world. They often cause serious damage to wooden furnitures and buildings. The damage caused by termites has an important economic effect. One of the important groups of urban insect pests in tropical countries is subterranean termites Coptotermes curvignathus Holmgren [2]. Termites are insects which are successfully to adapt in various condition of settlements and farms. Their ability to survive in settlements area is influenced by their life style which is colonized in big numbers [3]. The use of chemical teratments may bring a destructive effect to the environment
