The newly sequenced complete mitochondrial genome of the brown marmorated stink bug, Halyomorpha halys($St{\aa}l$) (Hemiptera: Pentatomidae), is a circular molecule of 16,518 bp with a total A+T content of 76.4% and two extensive repeat regions in A+T rich region. Nucleotide composition and codon usage of H. halys are about average when compared with values observed in 19 other published hemipteran mitochondrial genomes. Phylogenetic analyses using these 20 hemipteran mitochondrial genomes support the currently accepted hypothesis that suborders Heteroptera and Auchenorrhyncha form a monophyletic group. The mitochondrial gene arrangements of the 20 genomes are also consistent with our results.

Toxicity of several insecticides was tested against the brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae), and adult Gymnosoma rotundatum (Diptera: Tachinidae) in a sweet persimmon orchard. H. halys was captured using black light traps and G. rotundatum adults were collected using sticky traps lured with an aggregation pheromone, methyl-(E,E,Z)-2,4,6-decatrienoate of Plautia stali. Five insecticides, namely, bifenthrin 2 WP, buprofenzine+dinotefuran (20+15) WP, clothianidin 8 SC, dinotefuran 10 WP, and thiamethoxam 10 WP, were moderately toxic to G. rotundatum, resulting in 55.3% to 74.3% mortality. Bifenthrin 2 WP caused 93.1% mortality at 72 h within cages as a residual toxicity, and others caused varied mortalities.

This study was conducted to examine the feeding effect of Halyomorpha halys ($St{\aa}l$) (Hemiptera: Pentatomidae) on the fruit drop and decay rate of Mandarin citrus fruits (Citrus unshiu). The feeding of H. halys before fruit coloring caused a severe fruit drop, while the feeding after fruit coloring induced a low level of fruit drop. However, the feeding of H. halys before or after fruit coloring did not induce significant fruit decay during cold storage. The results are expected to be useful in managing H. hlays of late season mandarine, because citrus farmers follow calendar spray to prevent fruit drop and fruit decay.

Stink bugs do damage on various crops including upland crops and tree fruits. Especially, yellow-brown stink bug (Halyomorpha halys ($St{\aa}l$)) and brown-winged green (Plautia stali) are severely damaged on apple orchard. Using seven insecticides - dinotefuran WP, etofenprox WP, chlorpyrifos WP, cabaryl WP, chlothianidin SC, flonicamid WG, and bifenthrin WG - registered on apple, contact and residual toxicities were tested on both male and female of P. stali and H. halys that preferred apple fruit. Contact toxicity of dinotefuran WP was excellent on male P. stali 48 hours after treatment (HAT) with 96.7% and significant on male Halyomorpha halys 48 HAT with 74.5% but the others had low effect. Contact toxicity on these stink bugs were higher in male than female. All insecticides except flonicamid, residual effects were all effective on both male and female of P. stali, while chlorpyrifos and bifenthrin were showed higher residual toxicity on both male and female of H. halys in laboratory condition. Two insecticides, chlorpyrifos and bifenthrin, were selected for the field test. Bifenthrin have a high residual effect on P. stali until 5 days after treatment, but have a low residual toxicity on H. halys in the field test. Chlorpyrifos showed higher residual toxicity in the laboratory, however, showed low residual efficacy on two species stink bug onto the field.

This study was conducted to investigate the fruit damage according to the number of released stink bugs and date of adult introduced on non-astringent persimmon. The fruit damage differed significantly by the number, date, and the source of feed for Riptortus clavatus. Damages on the fruits appeared when five bugs were released to mother branches bearing fruits. Damages to the fruits was heavy in the case that bugs were introduced in September and October, compared with in June, July and August. Persimmon fruit damage was influenced significantly by the available sources to R. clavatus, persimmon fruit alone or additional supply of kidney bean (Phaseolus vulgaris) and water. Characteristic damage symptoms by R. clavatus showed only scars on the fruit skin, without fruit dropping. Halyomorpha halys (=mista) showed significantly higher fruit damage when they were released in July, August, and September compared with other periods. Number of H. halys to the fruit also showed significant differences in fruit damages. Five H. halys in July showed 100% damaged fruits. The fruit damage by Plautia stali was not significantly different according to dates of introduction but the number of insects gave significant differences in the fruit damage ratio at the level of 1, 3, 5 bugs introduced to the mother branche bearing friuts. The damage symptoms by P. stali was fruit dropping in July and August but from September damaged fruits were found in the branches.

The Samurai wasp, Trissolcus japonicus (Ashmead) (Hymenoptera: Platygasteridae) is recognized as a solitary parasitoid on eggs of the stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), an economic pest causing severe damage to fruits, in South Korea. The wasp appears to be a potential biological agent of the pest. In addition, T. itoi Ryu and T. nigripedius (Nakagawa) were found to parasitize eggs of Eurydema gebleri Kolenati and Dolycoris baccarum Linnaeus, respectively. Diagnostic characters and photographs are provided for identification, and host records of Korean Trissolcus species are also given.

The ovicidal effect of plant extract mixture (5%cinnamon extract + 10% citronella oil + 30% citrus oil + 10% derris extract + 20% neem extract + 25% penetrating surfactant) against several major insect pests was tested using the spraying method. In the case of stink bugs, eggs tended to die during hatching. When treated with a plant extract mixture (500-times solution), mortality for Halyomorpha halys, Riptortus clavatus, Eurydema dominulus, Trialeurodes vaprarorium, Bemisia tabaci, Spodoptera exigua, and Agrotis ipsilon reached as high as 100%. Therefore, it is believed that industrialization will be feasible in the future.

Halyomorpha halys (St${\aa}$l) (Hemiptera: Pentatomidae) is a typical polyphagous stink bug causing losses in several host plants including leguminous crops and fruits. Nutritional status of fruits such as apple and orange for the development of H. halys is not yet clear. We evaluated fruits of apple and orange with or without soybean-peanuts as food sources to investigate development, mortality and fecundity of the stink bug in a controlled condition. Those only fed on water could not develop into third instars. H. halys could not develop into fourth instar on apple only food. However, on an orange only food, 14% of H. halys emerged as adults. Those fed on orange only food had the longest development period (74.2 d). Total mortality of those fed on foods consisting of soybean-peanut ranged from 38 to 44%. In an average a female laid 169~190 eggs in a lifetime and those eggs had 81~83% hatchability. Results indicated that the apple fruit as a solo food source is an incomplete food for H. halys development while orange could support development of only few of the bugs.

Stink bugs (Hemiptera: Pentatomidae) are economically important pests of fruit trees in Korea. The aim of the present study was to survey the relative abundance of stink bugs on four stone fruits, maesil (Prunus mume Sieb. et Zucc), cherry (Prunus avium L.), plum (Prunus salicina Lindl), and peach (Prunus persica (L.) Batsch), from 2017 to 2019 in the field. Four stink bug species were observed, including Carbula putoni (Jakovlev), Dolycoris baccarum (L.), Halyomorpha halys (Stål), Plautia stali Scott. H. halys was the most abundant (65%), followed by P. stali (26%), C. putoni (7%), and D. baccarum (2%). H. halys was the dominant species in maesil, cherry, and peach fruits, whereas P. stali was the dominant species in plum fruits. Most (81%) of the stink bugs observed were adults, with nymphs accounting for only 19% of the observed specimens. More stink bugs were observed during the late season than during the early season. These finding suggest that control strategies should be developed for the management of H. halys and P. stali at harvest in stone fruit tree orchards in Korea.
