콩에 큰 피해를 주는 가로줄노린재의 형태적 특징 및 온도별 발육특성을 조사하였다. 알은 2줄씩 콩잎이나 꼬투리에 산란하고 원형에 가까우며, 암컷 성충의 체장은 9.8 mm, 수컷 성충은 8.7mm로 암컷이 수컷에 비하여 크다. 부화율은 20, 25, 30 및 에서 로 온도가 증가함에 따라 높아졌으며, 알의 평균발육기간은 20, 25, 30 및 에서 각각 10.7, 5.0, 4.0 및 3.0일이다. 에서 1령, 2령, 3령, 4령 및 5령 약충의 평균발육기간은 각각 3.2, 3.4, 3.4, 3.3 및 5.9일로 온도가 증가 할수록 발육기간이 짧아졌다. 각 태별 발육영점은도와 유효적산온도는 알은 와 65.5일도, 약충은 와 322.8일도, 알에서 약충까지는 와 386.4일도였다. 에서 산란전기간은 10.0일, 성충수명은 암컷이 52.5일, 수컷이 38.2일로 암컷이 수컷에 비하여 수명이 길었으며, 이때 성충 한 마리의 총 산란수는 496개였고, 난괴수는 21.5개였다.
This study was conducted to investigate morphological characteristics and effects of temperature on the development of Piezodorus hybneri on soybean. The unibanded stink bug, Piezodorus hybneri, is a serious insect pest in soybean fields giving damage to seeds in pod and leaves of soybean lowering both quality and yield. Eggs were spherical and laid in two raws on the leaves and pods of soybean plants. Body lengths of females and males were 9.8 mm and 8.7 mm, respectively. Egg hatch rates were better in higher temperature within the range of examined temperatures, which ranged in . The development periods of eggs at the temperatures of 20, 25, 30 and were 10.7, 5.0, 4.0, and 3.0 days, respectively. Mean developmental periods of 1st, 2nd, 3rd, 4th and 5th nymphs at were 3.2, 3.4, 3.4, 3.3 and 5.9 days, respectively. Development threshold and effective accumulative temperature were and 65.5 DD (day degree) for egg stage, and 322.8 DD for nymph stage, and 386.4 DD from egg to adult, respectively. Oviposition began from 10 days after emergence at , and the longevity of female and male were 52.5 and 38.2 days, respectively. Total number of eggs and egg masses laid by a female at were 496 and 21.3, respectively, The longevity of adult female was shortened with increasing temperature, whereas the total numbers of eggs laid by a female were decreased.
