  • The genus Caconemobius comprises marine apterous crickets. In recent years, two species have been confirmed in Korea: Caconemobius sazanami (Furukawa, 1970) and Caconemobius takarai ($\hat{O}$shiro, 1990). A key to species, descriptions, distribution data, photographs, and figures are presented to compare the two crickets.

  • The burrowing-cricket genus Velarifictorus Randell, 1964 is reviewed in Korea, comparing with morphologically resembled genus Lepidogryllus Otte and Alexander, 1983 for the first time. First, Velarifictorus aspersus borealis Gorochov, 1985 is confirmed from only restricted area of southern regions in Gyeongsangnam-do and Jeollanam-do. Second, Velarifictorus micado (Saussure, 1877) is confirmed from nearly all around the Korean peninsula including North Korea. Third, the previously not recorded Velarifictorus ornatus (Shiraki, 1911) is newly recognized from South Korea. Relating to the genus Velarifictorus, the resembled genus Lepidogryllus Otte and Alexander, 1983 and its species Lepidogryllus siamensis (Chopard, 1961) com. & stat. nov. is studied and compared with Velarifictorus members. A key, descriptions, tables, photographs, figures, oscillograms and spectrograms of calling sounds are provided to aid identification between the four similar species.

  • The field-cricket $Turanogryllus$ $eous$ Bey-Bienko, 1956 and its genus $Turanogryllus$ Tarbinsky, 1940 were recorded for the first time from Chungcheongbuk-do province in Korea to carry out the project 'The sound guides to Korean animals.' Depending on the discovery of the cricket, its distributional ranges are more widened towards East Asia to the Korean peninsula from China mainland, the $Turanogryllus$ was 10th to known Gryllinae genera in Korea. Description, photos of habitus, figure of male genitalia, oscillogram and spectrogram for the calling sound are provided for aid identification. Voucher specimens are deposited in the collection of National Institute of Biological Resources, Incheon, Korea.

  • The Korean population of the sword-tailed cricket subfamily Trigonidiinae is reviewed for the first time. Four members of the crickets are confirmed based on the examined material, those are Metioche japonica (Ichikawa, 2001), Svistella bifasciata (Shiraki, 1911), Homoeoxipha obliterata (Caudell, 1927) and Natula matsuurai Sugimoto, 2001, each of them belonging to a different genera. Among them, the former two are reconfirmed since earlier records, and latter two are newly recognized genera and species from the far southern provinces Jeollanam-do and Jeju-do Island in Korea. The type locality of both crickets is Japan, and are also only previously referred to in Japan, but their distributional ranges include neighboring South Korea. A key to the species, descriptions, photographs, figures, and oscillograms of male's calling sounds are provided to aid their identification.

  • Many insects have gained increasing attention as an alternative protein for humans. Among those, the two-spotted cricket, Gryllus bimaculatus (Orthoptera: Gryllidae), was recently approved as a general food ingredient by the Korean Ministry of Food and Drug Safety. For industrial utilization of G. bimaculatus, mass rearing techniques and production system should be standardized first. In this study, we investigated the effects of five different feeds on the growth and development of G. bimaculatus. Feed is the one of the key factors that has considerable effects on rearing insects. With five different kinds of feed on $1^{st}$, $3^{rd}$, and $5^{th}$ instar nymphs, the change of survival rate, body weight were monitored up to eight wk after hatching. We concluded that 50% of soybean flour, 20% of corn powder, 10% of rice bran, 9% of milk serum, 10% of rice flour, 0.5% of microorganisms, and 0.5% of multivitamins and minerals (diet C) was the best mix for promoting growth and development of $3^{rd}$ instar nymphs compared to the control diet.
