Diba et al (2013) demonstrated that EMWs can be used as a nondestructive method for termite control, which is very useful because EMWs are odourless and application is easy, noise-free, and environmentally friendly. In this study, and the R. ferrugineus in this study died immediately.…”

Rhynchophorus ferrugineus (Oliver) (Coleoptera: Curculionidae) is the primary pest of palms. Although several methods are used for its control, there is concern that insecticidal treatments can cause substantial environmental pollution. Therefore, the use of electromagnetic waves (EMWs) or microwaves (MWs) to control R. ferrugineus is an attractive alternative option. Microwave heating is increasingly used to manage a wide variety of agricultural and forest pests because it induces thermal death in insects that have a thermal tolerance lower than that of the host matrix. In this study, EMWs (360 Hz, 100 W) applied for 60 min caused 100% mortality of adult RPWs but had no effects on larvae. Microwave heating (2.45 GHz, 500 W) caused 100% mortality of adults in 4 min, whereas larvae required MW heating for only 40 s to achieve 100% mortality. The brain of adult R. ferrugineus was the most damaged region following EMW exposure, with severe damage to the neural cells after 60 min. The neural bundles were broken, and the granular cells were scattered. Microwave exposure affected the cuticle and muscles in adult R. ferrugineus after 4 min and the midgut, cuticle, and muscles in larvae after 40 s. The gut epithelium separated from the basement membrane and became highly vacuolated, almost disintegrating. The cuticle was reduced with separated layers, and muscle fibers were also affected. This work confirms that EMWs and MW heating are promising, ecocompatible methods to fight the spread of R. ferrugineus.

“…The design was based on some references [8][9][10]. The proposed concept mainly adopted the previous concept of the authors [11] by developing frequency range, compatibility and electromagnetic field range. In our previous research [11], the optimal frequency to repel the termites was about 300 kHz with a limitation on the electromagnetic field radius (5 -10 cm), limit of voltage in the higher frequency (about 2 Volt in frequency about 300 kHz) and its incompatibility (frequency and voltage setting had to use the oscilloscope).…”

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.

“…Specimens were photographed with a macro digital camera, and the original samples were using a microscope with a magnification of ×400. Termite samples were classified according to species identity, using information provided by Diba et al (2013), Subekti and Syahadan (2021), and relevant references. Termites were also identified by matching their characteristics with the key of determination in the book Biology of Termites by Kumar Khrisna and Frances M. Weesner Volume II 1969.…”

Abstract. Subekti N, Milanio RR. 2023. Termite diversity and abundance based on altitude in Mount Ungaran, Central Java, Indonesia. Biodiversitas 24: 3332-3337. Termites are social insects whose main diet is the cellulose and lignocellulose found in rotting wood and in some fungi. As the Mount Ungaran area in Central Java, Indonesia, has been converted to agriculture and other purposes, termite habitat has become increasingly narrow, with a reduction in the insects’ food sources. The purpose of this study was to analyze the species of termites found on Mount Ungaran and the factors that influence their lives. In addition, the differences in species according to slope (north, south, east, and west) and altitude were assessed. This research was conducted in three stages: termite collection, termite identification, and data analysis. The main species found in this study were Coptotermes curvignathus Holmgren, 1913, Odontotermes javanicus Holmgren, 1912, Macrotermes gilvus Hagen, 1858, Nasutitermes matangensis Haviland, 1898, and Bulbitermes constrictiformis Holmgren, 1914. Based on a Shannon-Wiener analysis, the west slope had the highest diversity index, which was primarily influenced by four environmental factors (soil pH, soil temperature, soil moisture, and rainfall). In the canonical relationship correspondence analysis, soil pH, light intensity, and canopy cover were the environmental factors that most affected the diversity and abundance of termites on Mount Ungaran. The conclusions that can be drawn from this study are that termite richness varied between slopes and the environmental factors that were the most associated with the variation were soil pH, light intensity, and canopy cover.
