Soon Do Bae,Hyun Ju Kim,Sung Tae Park 한국응용곤충학회 2012 Journal of Asia-Pacific Entomology Vol.15 No.1

The attractiveness of live adult stink bugs used as baits in traps in soybean fields, Milyang, Korea, to conspecific stink bugs was evaluated. Both sexes of bean bug, Riptortus pedestris Fabricius (Hemiptera: Alididae), and one-banded stink bug, Piezodorus hybneri Gmelin (Hemiptera: Pentatomidae), were attracted to conspecific male adults-baited traps. Likewise, both sexes of brown-marmorated stink bug, Halyomorpha halys Stål (Hemiptera: Pentatomidae), and sole bug, Dolycoris baccarum L. (Hemiptera: Pentatomidae), were attracted to traps baited with conspecific male stink bugs. However, in Nezara antennata Scott (Hemiptera: Pentatomidae),both male and female used as baits in traps were attractive to conspecific adults. Accordingly, these results suggest that the only male adults of H. halys and D. baccarum and both sexes of N. antennata are attractive to conspecific male stink bugs.

배순도(Soon-Do Bae),김현주(Hyun-Ju Kim),윤영남(Young-Nam Yoon) 충남대학교 농업과학연구소 2012 농업과학연구 Vol.39 No.4

Preference of stink bugs to various leguminous seeds was evaluated by using VTS (Video Tracking System) in laboratory. Major soybean stink bugs such as bean bug, Riptortus pedestris (Fabricius), one-banded stink bug, Piezodorus hybneri (Gmelin), eastern green stink bug, Nezara antennata (Scott), and sole bug, Dolycoris baccarum (L.) were significantly most attracted to Cheongjakong, a soybean variety, baited fish-net trap, followed by soybean varieties Ilpumgeomjeongkong and Taekwangkong, a peanut variety Daekwangdangkong, a kidney bean variety Gangnangkong, and a adzuki bean variety Jungwonpat, respectively in a soybean field. VTS observation in laboratory showed that R. pedestris and D. baccarum had significantly higher frequency of visit on Cheongjakong, followed by Ilpumgeomjeongkong. However, P. hybneri, N. antennata and Halyomorpha halys (Stal) had significantly higher number of visits on Cheongjakong, Seonnogkong and Jinpumkong, followed by Ilpumgeomjeongkong. The sojourned time of stink bugs, however, was significantly longer on Cheongjakong regardless of species of the bugs. Accordingly, Cheongjakong was evaluated as the most preferred soybean seed by fish-net trap and VTS. Thus, VTS is found to be an effective means to evaluate the food preference of stink bugs.

This study was conducted to investigate the application effect of Lysobacter antibioticus HS124 (gelatinase and chitinase producing microorganism; GCM) for the improvement of soybean yield and control of stink bug. Our results showed that the yield of GCM-treated soybean increased by 17.0, 20.3, 19.0, and 25.6% in the experimental field sites of Muan-gun, Sunchang-gun, Gwangju 1, and Gwangju 2, respectively, compared to the yield of the soybean obtained by conventional practice treatment (CPT); however in the Gimjae-si, the yield decreased by 10.6%. Results in both pods and seeds plant<SUP>-1</SUP> were significantly increased in Gwangju 2 by the GCM cultured broth treatment (GCMT). Ratio of 3 seeds pod<SUP>-1</SUP> in Sunchang-gun was statistically significant between GCMT and CPT, however, the result in the other field showed no significance. Germination rate was only statistically improved by GCMT in Gwangju 2 field site. GCMT reduced the appearance of stink bug in all experimental field sites except in Gimjae-si. The soybean seed damage by stink bug was no significance in all of treatments. Therefore, GCMT could improve the productivity of soybean and also control the infestation of stink bug.

Green Stink Bug (Hemiptera: Pentatomidae) Recorded as a New Pest of Olive in India

Kaul, V.,Tiku, A.K.,Shankar, Uma,Monobrullah, Md. Korean Society of Applied Entomology 2007 Journal of Asia-Pacific Entomology Vol.10 No.1

During the survey of olive orchards in Jammu and Kashmir, various insect pests were recorded infesting olive which include, olive psylla, olive black scale, scarab beetle and green stink bug. Among these green stink bug, Nezara virudula (L.) [Hemiptera: Pentatomidae] has been recorded for the first time in India.

Developmental Rate of Halymorpha halys (Hemiptera:Pentatomidae) Fed on Different Food Sources

Bishwo P Mainali,Soon-Do Bae,Hyun-Ju Kim,Young-Nam Yoon,In-Seok Oh 한국응용곤충학회 2013 한국응용곤충학회 학술대회논문집 Vol.2013 No.04

The brown marmorated stink bug Halyomorpha halys Stål (Hemiptera: Pentatomidae), is native to Korea, Japan, and China. H. halys is one of the major polyphagous pentatomids with a wide host range encompassing ornamental shrubs, trees, and cultivated crops such as millet, sesame, soybean, apple, yuzu, pear, cherry, and peach and inflicting losses of several crops in Korea. However, study on dietary importance of these hosts on the development rate of H. halys is sparse. We evaluated fruits of apple and orange with or without soybean plus peanuts as food sources to investigate development rate, mortality and fecundity of the stink bug. Not apple but orange only diet could support development up to adult stage but with higher mortality. First instars were found to molt into second instars without feeding. The longest time H. halys took to develop was in its fifth instar. Overall shortest developmental period (39.82) days was recorded on those fed on orange+soybean and peanut whereas those fed on orange only diet had longest development period (78.92 days). Generational mortality of those fed on diets consisting of soybean and peanuts ranged from 43 to 53%. Those only fed on water could not develop into third instars. H. halys could not develop into fourth instar in apple only diet. However, on orange only diet 20% H. halys could emerge as adults. Fecundity was measured for the first day of oviposition per female. Fecundity was recorded highest (28 eggs) on orange+soybean and peanut diets. The results suggest that H. halys require leguminous seeds in order to develop fully and lay fertile eggs.

Sin Ae Jang,박정규 한국응용곤충학회 2010 Journal of Asia-Pacific Entomology Vol.13 No.1

The brown-winged green stink bug, Plautia stali Scott (Hemiptera: Pentatomidae), is an important fruitpiercing bug. A monitoring study on the seasonal density change of P. stali using traps baited with methyl (E,E,Z)-2,4,6-decatrienoate, the aggregation pheromone of the P. stali, resulted in the first capture of adult tachinid flies, Gymnosoma rotundatum (Diptera: Tachinidae), in Korea. The parasitoid fly may worth studying as a biological control agent in the management of P. stali.

Use of aggregation pheromone traps increases Riptortus pedestris (Hemiptera: Alydidae) populations in soybean fields during the fall season

M. Mahbubur Rahman,Un Taek Lim 한국응용곤충학회 2015 한국응용곤충학회 학술대회논문집 Vol.2015 No.04

Riptortus pedestris (F.) (Hemiptera: Alydidae) is an important pest of soybeans in Korea and Japan. A synthetic aggregation pheromone trap has been commercialized and used in soybean fields in Korea for both monitoring and mass-capture of this bug. As the trap’s efficacy in reducing the pest population or crop damage is unknown, in this study we evaluated the aggregation pheromone trap in experimental soybean fields located in Andong National University. Two treatments, one with traps deployed for the entire cultivation period and one with no traps, were tested in six small experimental fields. The total numbers of R. pedestris (in all life stages) in soybean field were not significantly different between the treatments until August. But, in presence of pheromone, the pest’s abundance increased significantly in September and October. Relative to the size of the bug population in the field, trap catch rate was low during the fall (when bug density was highest) and high in early summer when the field population was very low. Placement of aggregation traps in plots caused pod and seed damage from R. pedestris to increase 2.7 and 2.2 times compared to the control. In conclusion, R. pedestris populations increased significantly during the fall in the presence of the aggregation pheromone trap, which should therefore be used with great caution whether as a control measure or as a monitoring tool.
