Laboratory studies with the stink bug Chinavia erythrocnemis (Berg) (Hemiptera: Pentatomidae) were conducted to evaluate the effect of reproductive structures of cultivated plants, on nymph and adult performance, and adult preference. Results indicated that nymphs were able to complete the development on all plants evaluated. Nymph developmental time was significantly shorter on immature soybean pod [Glycine max (L.) Merrill], compared with immature green bean pod (Phaseolus vulgaris L.), immature siliques of canola (Brassica napus L. var. oleifera), and immature ear heads of wheat (Triticum aestivum L.). Nymph survivorship was superior on soybean (60%), decreasing on the remaining food sources (< 38%). Fresh body weight of females and males at adult emergence was higher on green bean and on soybean, compared with wheat and canola. Survivorship of adults after 40 days was highest on soybean (80%) and on green bean (65%), and lowest on canola (25%). Females of C. erythrocnemis reproduced on all food sources tested, except on canola, on which no female laid eggs. The fecundity and longevity of adults were significantly higher on green bean and on soybean compared with wheat and canola. In general, adults gained weight over time when fed on green bean (18%), followed by soybean (3.4%). On wheat and on canola, the bugs lost weight over time (− 14.9% and − 27.4%, respectively). In general, soybean pod was preferred compared with green bean, canola, and wheat; green bean was preferred over wheat and canola; and canola was preferred to wheat.

红蝽（异翅目：蝽科）对栽培植物生殖结构的表现和偏好


对臭虫Chinavia erythrocnemis (Berg)（半翅目：蝽科）进行了实验室研究，以评估栽培植物的生殖结构对若虫和成虫表现以及成虫偏好的影响。结果表明，若虫能够在所有评估的植物上完成发育。与未成熟绿豆荚 ( Phaseolus vulgaris L.)、未成熟油菜长角果 ( Brassica napus L. var. oleifera ) 和未成熟穗相比，未成熟大豆荚 [ Glycine max (L.) Merrill] 上的若虫发育时间显着缩短小麦（ Triticum aestivum L.）的头。若虫在大豆上的存活率较高（60%），在其余食物来源上的存活率则下降（< 38%）。与小麦和油菜相比，绿豆和大豆的雌性和雄性成年羽化时的鲜重较高。 40 天后，大豆（80%）和绿豆（65%）成虫的存活率最高，油菜籽（25%）最低。雌性C. erythrocnemis在所有测试的食物来源上繁殖，但双低油菜籽除外，油菜籽上没有雌性产卵。与小麦和油菜相比，绿豆和大豆上的成虫的繁殖力和寿命显着更高。一般来说，吃绿豆（18%）的成年人体重随着时间的推移而增加，其次是大豆（3.4%）。在小麦和油菜上，昆虫的体重随着时间的推移而减轻（分别为− 14.9％和− 27.4％）。总体而言，与绿豆、油菜、小麦相比，大豆荚更受青睐；绿豆优于小麦和油菜；油菜籽比小麦更受欢迎。
