The purpose of this study is to observe the period of mating calls of cicadas in South Korea to identify the emergence period and geographic distribution for each cicada species. The study sites were 19 protection areas nationwide. The mating calls of cicadas were collected over the 12 months of 2019. A bioacoustics measuring device was installed to record the mating calls of cicadas in WAV, 44,100Hz format for 1 minute every hour. The temperature was recorded once or twice every hour using a micro-meteorological measuring device. Nine species of Korean cicadinae were studied. The start and end periods of mating calls were recorded for each cicada species for the subsequent analysis. The analysis results showed that nine cicada species appeared in the 19 protection areas. The chronological order of mating call periods for each species was as follows: Cryptotympana atrata (7/12 - 9/30), Meimuna opalifera (7/27 - 10/20), Hyalessa fuscata (7/25 - 10/9), Graptopsaltria nigrofuscata (7/28 - 9/5), Platypleura kaempferi (7/3 - 9/29), Suisha coreana (9/14 - 10/30), Leptosemia takanonis (6/26 - 8/2), Auritibicen intermedius (7/27 - 9/28), and Meimuna mongolica (8/8 - 9/11). The mating call period was between 35 (Meimuna mongolica) and 89 (Platypleura kaempferi) days, with the average being 62 days. The elevation above sea level for the habitats of each species was as follows: 5 - 386 m for Cryptotympana atrata, 7 - 759 m for Meimuna opalifera, 7 - 967 m for Hyalessa fuscata, 42 - 700m for Graptopsaltria nigrofuscata, 7 - 700 m for Platypleura kaempferi, 5 - 759 m for Suisha coreana, 7 - 759 m for Leptosemia takanonis, 397 - 967 m for Auritibicen intermedius, and 7 - 42 m for Meimuna mongolica. The average temperature of the habitats of each species was as follows: 23.9℃ for Cryptotympana atrata, 21.8℃ for Meimuna opalifera, 22℃ for Hyalessa fuscata, 23℃ for Graptopsaltria nigrofuscata, 22.9℃ for Platypleura kaempferi, 14.6℃ for Suisha coreana, 20.6℃ for Leptosemia takanonis, 19.3℃ for Auritibicen intermedius, and 24.4℃ for Meimuna mongolica. In terms of the habitat distribution of species, Meimuna opalifera, Hyalessa fuscata, and Platypleura kaempferi were distributed in more than 15 protection sites. Cryptotympana atrata was distributed in the lowlands in the southwest. Graptopsaltria nigrofuscata was distributed in the western area of the Korean Peninsula. Suisha coreana was distributed in areas excluding high mountain areas and parts of the southeast area. Leptosemia takanonis was distributed in areas near the mountains. Auritibicen intermedius was distributed locally in the high mountain areas. Meimuna mongolica was distributed locally in flat wetlands.

Two newly recorded species of the genus Arboridia Zachvatkin (Hemiptera: Auchenorrhyncha: Cicadellidae: Typhlocybinae) from Korea are reported, which are Arboridia lunula Song & Li, 2013 and Arboridia agrillacea (Anufriev, 1969). Photographs of dorsal habitus, illustrations of male genitalia, abdomens and forewings and distributional records are provided. In addition, a key to the Korean Arboridia species is also given.

An aphid species, Glyphina betulae( Linnaeus, 1758), which has been known only in western Paleoarctic, is recognized from Mt. Baekdu-san, North Korea. Besides the descriptions and illustration for apterous viviparous female and alate viviparous female, brief biology, host plahts and distribution are discussed. This is the first record of the genus Glyphina in Korean Peninsula.

A leafhopper, Zorka sp. was collected from a persimmon (Diospyrosi kaki, cv SangjuDungsi) orchard in Sangju, Gyeongsangbuk-do, Korea on 15 June, 2008. This leafhopper gave a serious damage to persimmon leaves, being a new pest to persimmon. This leafhopper was tentatively identified as Zorka sp., which has not been recorded in the science. White spots of <1mm-circle occurred around the vein of damaged leaves. Most part of leaf was turned to white when heavy infection occurred. The first symptom occurred from 4 days after introduction of Zorka sp. (4 adults/persimmon leaf). We investigated the occurrence of Zorka sp. in the persimmon orchards in Korea from 2008 to 2009. Total 143 orchards from 11 cities in 6 provinces were observed from July to August. The damage caused by Zorka sp. was found in 22 orchards (15.4%) of the investigated. According to locality, 40.7% of orchards were damaged in Yeongdong, Chungcheongbuk-do and 33.3% in Wanju, Jeollabuk-do. However, no damage was observed from the orchards in Gyeongsangnam-do and Jeju-do, south part of Korea. Especially, 9 of 11 orchards in Youngdong were located close to grapevine yards.
