| 中文摘要: |
| 储蓄植物系统作为一种开放式的天敌饲养系统，越来越多地应用到温室及田间的害虫防治。南方小花蝽 Orius similis Zheng 可捕食蓟马、蚜虫等多种害虫，是农业上一类极具应用价值的捕食性天敌。为提高南方小花蝽的控害效果，建立南方小花蝽储蓄植物系统是一种极为有效的方法。为了筛选适用于南方小花蝽保育和增殖的储 蓄植物，进而构建南方小花蝽储蓄植物系统，本研究选择了月季 Rosa chinensis、长寿花 Narcissus jonquilla、辣椒 Capsicum annuum、黄瓜 Cucumis sativus 和蚕豆 Vicia faba 作为候选的储蓄植物，通过六臂嗅觉仪分析了南方小花蝽对 5 种植物花朵的气味选择性，同时分析了南方小花蝽在 5 种植物上的繁殖系数、发育历期、存活率等生物学参 数。结果表明 43.33% 的南方小花蝽雌虫偏好辣椒花朵气味，其次为蚕豆 ( 26.67% ) ; 南方小花蝽卵的孵化率在辣椒上最高达到 95.59%，其次为蚕豆为 80.74% ; 同时，南方小花蝽卵在蚕豆上的发育历期显著低于另外 4 种植物，仅有 4.92 d。综上所述，本研究初步认为辣椒和蚕豆比较适合用来构建南方小花蝽储蓄植物系统。 |

| As a natural enemy open-rearing system，banker plant system is increasingly applied to pest control in greenhouses and fields. Southern flower bug ( Orius similis Zheng) can prey on pests such as thrips and aphids etc.，is a predatory natural enemy with great application value in agriculture. Establish a southern flower bug banker plant system is an effective method to improve the control efficacy of the predator. In order to screen the suitable banker plant for the conservation and propagation of the southern flower bug，and construct a southern flower bug banker plant system. We choose Rosa chinensis，Narcissus jonquilla，Capsicum annuum，Cucumis sativus and Vicia faba as candidate banker plants，then analyzed odor preference of the southern flower bug by six-arm olfactometer. Besides，we also analyzed the biological parameters such as propagation coefficient，developmental duration and survival rate. The results showed that 43. 33% of the southern flower bug females preferred the odor of C. annuum flowers，followed by that of V. faba ( 26.67% ) . The eggs of southern flower bug had the highest hatching rate of 95. 59% on C. annuum，followed by 80.74% on V. faba. Meanwhile，the egg development duration of southern flower bug on V. faba was only 4. 92 days，which was significantly lower than that of the rest candidate banker plants. In total，we preliminarily considered that C. annuum and V. faba are more suitable for the establishment of southern flower bug banker plant system. |
