썩덩나무노린재(Hemiptera: Pentatomidae)의 발육을 15, 20, 23, 25, 30℃에서 조사하였다. 종령기까지 발육을 완성한 온도는 20℃와 23℃이었다. 20℃와 23℃에서 약충기간은 각각 46.9일과 35.5일이었으며, 1령 기간이 가장 짧고 5령기간이 가장 길었다. 실험에 사용한 최저 온도인 15℃에서는 2령까지, 30℃에서는 4령까지 발육하는 동안에 모든 개체가 사망하였다. 암수 성충의 수명은 20℃에서는 각각 53.6일과 45.3일이었고, 23℃에서는 각각 50.1일과 68.1일이었다. 암컷 당 총 산란수는 20℃에서는 135.8개, 23℃에서 242.9개이었다. 알에서부터 성충우화까지 필요한 평균 적산온도(발육영점온도 13.94℃ 적용)는 20℃와 23℃에서 각각 314.5 일도와 367.8 일도이었다. 그 외에 약충의 각 령기별 발육기간과 사망율, 산란전기간과 산란후기간, 산란횟수별 산란수, 알에서 산란전기간까지의 적산온도 등이 조사되었다.
Temperature-dependent development and oviposition of Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) were examined under five temperature regimes, 15, 20, 23, 25, and 30℃. Temperatures at which the bugs emerged successfully to final nymphal stage were 20 and 23℃. Nymphal period was 46.9 and 35.5 days at 20 and 23℃, respectively. The developmental period of the 1st instar nymphs was shortest, and that of the 5th instar nymphs was longest. Under the lowest(15℃) and the highest (30℃) temperatures, all the nymphs died during the development until the 2nd and 4th instar, respectively. Adult longevity of females and males were 53.6 and 45.3 days at 20℃, and 50.1 and 68.1 days at 23℃. A female layed 135.8 and 242.9 eggs at 20 and 23℃, espectively, during her life span. The total effective temperature, based on the developmental zero point of 13.94℃, was 314.5 and 367.8 degree days under 20℃ and 23℃, respectively. In addition to those parameters, developmental period and mortality of each instar, pre- and post-oviposition periods, number of eggs per oviposition, and degree day from egg to pre-oviposition period was examined.
