“…(Thielens et al, 2018) exposed four different types of insects to continuous electromagnetic fields at various frequencies from 2 to 120 GHz. (Sanborn, 2008) and (Nakai et al, 2009) suggest that such absorption causes dielectric heating that affects insect behavior, physiology, and morphology. In the present work, the non-thermal effects of EMWs on adult R. ferrugineus produced significant histopathological alterations and mortality.…”

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.

“…Microsatellite loci were amplified using a Type-it Microsatellite PCR Kit (Qiagen, Hilden, Germany) and either a mixture of the forward and reverse primers of Rs02 , Rs03 , Rs05 , and Rs07 for R. speratus or a mixture of the forward and reverse primers of Cf4-4 , Cf4-9A , Cf8-4 , and Cf10-5 for C. formosanus according to the manufacturer’s protocol. The PCR conditions were 30 cycles of 30 s at 95 °C, 90 s at 60 °C, and 30 s at 72 °C [ 21 ]. PCR products were resolved on an ABI Prism 3100 Genetic Analyzer (Applied Biosystems, Waltham, MA, USA).…”

We assessed the efficacy of a discontinuous soil treatment using a diluent of fipronil suspension concentrate in controlling colonies of Coptotermes formosanus and Reticulitermes speratus. In-ground monitoring stations were installed at Isogi Park and Kindai University, and individual termites inhabiting the stations were collected for four or six years to determine the numbers and locations of colonies present in test areas before and after the discontinuous soil treatment. Microsatellite genotyping indicated that two C. formosanus and two R. speratus colonies in the test area at Isogi Park and five R. speratus colonies in the test area at Kindai University were active and that their territories fluctuated every year. One of the two C. formosanus colonies at Isogi Park and one of the five R. speratus colonies at Kindai University were subjected to discontinuous soil treatments with fipronil and were strongly affected by the treatment at the colony level, resulting in the suppression and possible elimination of colonies. Termite activity of the fipronil-treated colony of C. formosanus was detected within one week after the discontinuous soil treatment and was not found for more than two years (28 months), while termite activity of the fipronil-treated colony of R. speratus was detected within four days and three weeks after the discontinuous soil treatment and was not detected thereafter for three years. Fipronil residue analysis showed that workers of C. formosanus moved at least 28 m and that workers of R. speratus moved 6 m from the treated soil locations for up to three weeks.

The species status of Japanese populations of Incisitermes immigrans from Iwo and Minami Daito Islands was examined using mitochondrial 16S molecular barcode sequences. The molecular sequences of these two populations were compared to those of other Incisitermes spp. deposited in the GenBank database using a maximum likelihood phylogenetic analysis. This analysis suggested that the Minami Daito population is indeed I. schwarzi, as suspected previously, while the sequence of the Iwo Island population was identical to that of authentic I. immigrans. In addition to I. minor, which is recorded from middle and southern Japan, the presence of three Incisitermes species in Japan was confirmed.
