썩덩나무노린재는 두과작물에서 과실에 이르기까지 다양한 작물을 가해하는 대표적인 다식성 노린재의 일종이다. 과실이 썩덩나무노린재의 발육에 필요한 영양원인지 불필요한 영양원인지 아직도 분명하지 않다. 그리하여 사과와 오렌지의 단독먹이 및 콩-땅콩과의 먹이조합에 따른 썩덩 나무노린재의 발육, 사망률 및 증식률을 평가하였다. 썩덩나무노린재 약충은 사과단독먹이에서만 높은 사망률로 성충으로 발육하지 못하였다. 물 만 제공한 것은 3령으로 발육하지 못하였고, 사과단독먹이에서 4령으로 발육하지 못하였다. 하지만 오렌지단독먹이에서 14%가 성충으로 우화하 였으나, 약충의 발육기간이 약 74일로 가장 길었다. 콩-땅콩과 조합한 먹이에서 노린재의 사망률은 38~44%를 나타내었다. 총 산란수는 169~190 개 였으며, 부화률은 81~83%이었다. 따라서 사과는 썩덩나무노린재의 발육에 불완전한 먹이 이었으나, 오렌지는 발육이 지연되기는 하였으나 이루지는 것으로 평가되었다.

In a previous study, aggregation pheromone trap added with refrigerated eggs of Riptortus pedestris (Fabricius) (Hemiptera: Alydidae) in a netted pouch was found to enhance parasitism by its egg parasitoid Ooencyrtus nezarae Ishii (Hymenoptera: Encyrtidae) in soybean fields. However, the eggs released in the netted pouch would not be well exploited by the egg parasitoid due to reduced encounter of the eggs and elevated inter- or intraspecific competition among the parasitoids in clumped condition of released eggs inside the pouch. To solve this problem, new trap was developed with twelve separate cells for egg placement. Efficiency of this new trap was evaluated in a soybean field in Songcheon, Andong. Newly developed trap and formerly designed trap each with 180 refrigerated eggs were placed at a distance of 15-20m in the field. The released eggs were collected every week, and the experiment was replicated for three weeks. In addition, comparison was carried out by placing eggs in different density in the cell (120 in total per trap) for three weeks. Parasitism in newly developed trap (32-35%) was higher than that in the former trap (16-20%). Parasitism in the trap where eggs were released in six cells was the highest, followed by three cells, one cell, and eggs released in the pouch. From these findings, newly developed traps is better than previous design in enhancing the parasitism in soybean fields.
