The subfamily Rogadinae is a cosmopolitan and species-rich (Zaldívar-Riverón et al., 2008). The genus Aleiodes is the largest genus in the Rogadinae, with 632 species recorded worldwide, comprising more than half of the number of species in this subfamily (Yu et al., 2016;Sulca et al., 2016).
Aleiodes spp. are found in association with caterpillars that feed in large shrubs and role in regulating the density of forest pests. Therefore It is a species with potential as a biological control agent at forest (Shaw, 2006;Beyarslan, 2015). They are koinobiont-endoparasitic wasps characterised by the mummification of the host caterpillar, attack a variety (Zaldívar- Riverón et al., 2008). Most rogadine adults are primarily nocturnal and are among the braconids attracted by light (Wharton et al., 1997). Various morphological studies have been attempted to clarify the specific taxonomy of Rogadinae (Butcher et al., 2012;Jasso-Martínez et al., 2021). Despite phylogenetic the previous studies (Wharton et al., 1997;Sulca et al., 2016), the composition and relationships of Rogadinae are still not fully resolved (Jasso-Martínez et al., 2021).
In this study, we report genus of four Aleiodes species in South Korean. Here, redescription, diagnosis, distribution, illustrations and also DNA barcode sequences are provided for identification these species
Materials and Methods
The specimens collected by light trap and sweeping, South Korea. The samples were preserved in 75% ethyl alcohol. The species studied are deposited in Kunsan National University (KSNU). The terminology used for morphological characters follows van Achterberg (1988). For observation and photography, LEICA DMC2900 digital camera and LEICA M205 C microscope (Leica Geosystems AG) were used. Images were stacked by using Helicon software (Helicon Soft). Abbreviations are as follows: A; analis, CU; cubitous vein, SC; subcostal vein, M; Media, R; radial vein, SR; subradial vein, T; tergite.
Each specimen was used for the DNA extraction using a LaboPass Tissue Mini DNA isolation Kit (COSMO Genetech, Daejeon, Korea); there is the modification from ‘non-destructive method’ (Favret, 2005) that the first to third steps from the original protocol were modified, as called ‘freezing method’ (Yaakop et al., 2009). The sample which was not destroying is soaked with 200㎕ of a tissue lysis buffer with proteinase K solution 20㎕. The sample with solution incubated at 55°C for 10 minutes and then kept in a freezer at -22°C (least 3 hours to overnight). The primers LCO-1490 (5’-GGTCAACAAATCA TAAAGATATTGG-3’) and HCO-2198 (5’-TAAACTTCAG GGTGACCAAAAAATCA-3’) were used for amplification. The polymerase chain reaction (PCR) amplification which was amplified by using AccuPowerH PCR PreMix (BIONEER, Corp., Daejeon, Korea) in 20 ㎕ reaction mixtures containing 0.4μM of each primer, 20 μM of the dNTPs, 20 μM of the MgCl2, and 0.05 ㎍ of the genomic DNA template was performed using a GS1 thermo-cycler (Gene Technologies, Ltd., Essex, UK). We followed the procedure: initial denaturation at 95°C for 5 min, followed by 34 cycles at 94°C for 35 sec; an annealing temperature of 48°C for 25 sec; an extension at 72°C for 45 sec, and a final extension at 72°C for 5 min. The PCR products were visualized as a single band by electrophoresis on a 1.5% agarose gel. After electrophoresis, an amplified product was purified using a QIAquick PCR purification kit (QIAGEN, Inc., Milan, Italy), and then sequenced using an automated sequencer at Macrogen Inc. (Seoul, South Korea).
