Recently, peach orchards Plautia stali, Halyomorpha halys, Apolygus spinolae, etc. several species of stink bugs continually damaged. This study using a aggregation pheromone were Riptortus clavatus forecasting investigated at cheongdo, Gyeongsan, Youngchun, etc. gyeongbuk province. As a result, emergence time and population density differences, respectively. The population density of R. pedestris the first time that occur was in mid-April in 2011 and 2012. In March 2013, under the influence of high temperatures in the first occur early April after a temporary increase in the first occur, due to low temperature occur in the early or mid May. Stink bugs leaf damage late April until mid-May increased, while the decrease rainy season increased again in the early August. fruit is severe damaged from mid-May to mid-June and early or mid August. Time period pesticide applications to examine the control effect of stink bugs from 7 a.m. to 7 p.m. separated by four kinds of insecticides treatment. when spray insecticides 7 a.m. the control effect was higher in the treatment group. These results suggest that, stink bugs of the peach fruit through the feeding area, young fruit stage Xanthomonas arboricola pv. pruni and maturation stage Monilia fruticola secondary increased a cause of disease damage.
