Abstract

Snap bean is an important crop in the United States. Insecticides are commonly used against pests on snap bean, but many pests have developed resistance to the insecticides and beneficials are threatened by the insecticides. Therefore, host plant resistance is a sustainable alternative. Population dynamics of insect pests and beneficials were assessed on 24 snap bean cultivars every week for six weeks. The lowest number of sweetpotato whitefly () eggs was observed on cultivar 'Jade', and the fewest nymphs were found on cultivars 'Gold Mine', 'Golden Rod', 'Long Tendergreen', and 'Royal Burgundy'. The numbers of potato leafhopper () and tarnished plant bug () adults were the lowest on cultivars 'Greencrop' and 'PV-857'. The highest numbers of adults were found in Week 1 (25 days following plant emergence) for and Mexican bean beetle (); Week 3 for cucumber beetle, kudzu bug (), and ; Weeks 3 and 4 for thrips; Week 4 for ; and Weeks 5 and 6 for bees. Temperature and relative humidity correlated with , , bee, and predator ladybird beetle populations. These results provide valuable information on the integrated pest management of snap beans.

摘要

菜豆是美国的一种重要作物。杀虫剂常用于防治菜豆害虫，但许多害虫已对杀虫剂产生抗性，益虫也受到杀虫剂的威胁。因此，寄主植物抗性是一种可持续的替代方法。连续六周每周对24个菜豆品种上的害虫和益虫种群动态进行评估。在‘翡翠’品种上观察到甘薯粉虱（）卵的数量最少，在‘金矿’、‘金棒’、‘长嫩绿’和‘皇家勃艮第’品种上发现的若虫数量最少。马铃薯叶蝉（）和牧草盲蝽（）成虫的数量在‘绿色作物’和‘PV - 857’品种上最少。对于和墨西哥豆瓢虫（），成虫数量在第1周（植株出苗后25天）最高；对于黄瓜甲虫、葛藤蝽（）和，成虫数量在第3周最高；对于蓟马，成虫数量在第3周和第4周最高；对于，成虫数量在第4周最高；对于蜜蜂，成虫数量在第5周和第6周最高。温度和相对湿度与、、蜜蜂和捕食性瓢虫种群相关。这些结果为菜豆的综合害虫管理提供了有价值的信息。
