摘要

在美国,木本植物、果仁和果园,包括山核桃,都有重要的经济害虫。其中,颗粒ambrosia甲虫,Xylosandrus crassiusculus (Motschulsky)是佐治亚州山核桃果园中最常见的物种。各种诱捕器,包括乙醇介导的Lindgren多漏斗诱捕器、面板诱捕器、瓶诱捕器、粘卡和注入乙醇的木螺栓,用于凤仙花甲虫监测项目。陷阱的颜色和放置高度是提高陷阱效果的重要因素。为了提高捕集器的捕集效果,在野外条件下,利用黑色、蓝色、绿色、红色、透明和黄色6种不同颜色的粘卡,将粘卡放置在距离地面15、60和120 cm的3个不同高度,进行了颜色和高度偏好实验。结果表明,与所有其他测试颜色的粘性卡相比,红色和透明粘性卡始终捕获更多的ambrosia甲虫,而黄色粘性卡始终捕获较少的ambrosia甲虫。在田间和实验室环境中,对粗骨棘球绦虫也观察到类似的趋势。在评价的捕集器高度中,放置在离地面60 cm高度的粘卡中,始终捕获到更多的仙甲虫,其中包括长穗天牛。此外,我们在佐治亚州的商业山核桃果园监测了ambrosia甲虫的自然侵扰,发现与上部相比,靠近地面(45厘米)的山核桃树受到的损害更大。此外,我们还记录到3种ambrosia甲虫:X. crassiusculus,黑茎螟,X. germanus (Blandford)和东南亚ambrosia甲虫Xylosandrus amputatus (Blandford)。其中,山核桃园中最丰富的物种是X. crassiusculus(90.50%)。因此,放置在45 ~ 60 cm高度的红色透明粘卡可以提高诱捕效果,可用于山核桃果园的夜蛾监测。

Effects of Trap Color and Placement Height on the Capture of Ambrosia Beetles in Pecan Orchards.

Ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) in the tribe Xyleborini are economically important pests of woody ornamentals, tree nuts, and fruit orchards, including pecans in the United States. Among them, the granulate ambrosia beetle, Xylosandrus crassiusculus (Motschulsky), is the most common species in pecan orchards in Georgia. Various traps, including ethanol-mediated Lindgren multi-funnel traps, panel traps, bottle traps, sticky cards, and ethanol-infused wooden bolts, are used in ambrosia beetle monitoring programs. Trap color and placement height are important factors that increase trap effectiveness. To improve trap effectiveness for ambrosia beetles, we conducted a color and height preference experiment under field conditions using six different colored sticky cards, including black, blue, green, red, transparent, and yellow, placing them at three different heights (15, 60, and 120 cm from ground level). The results show that red and transparent sticky cards consistently captured a higher number of ambrosia beetles, whereas yellow-colored sticky cards consistently captured a lower number of ambrosia beetles compared to all other tested colors of sticky cards. A similar trend was observed with X. crassiusculus in field and laboratory settings. Among the evaluated trap heights, more ambrosia beetles, including X. crassiusculus, were consistently captured in the sticky cards placed at a height of 60 cm from the ground surface. Additionally, we monitored natural infestations of ambrosia beetles in commercial pecan orchards in Georgia and found more damage to pecan trees near the ground surface (45 cm) compared to the upper parts. We also recorded three ambrosia beetle species, X. crassiusculus, the black stem borer, X. germanus (Blandford), and the Southeast Asian ambrosia beetle, Xylosandrus amputatus (Blandford). Among them, X. crassiusculus (90.50%) was the most abundant species in the pecan orchards. Therefore, red and transparent sticky cards placed at a height of 45 to 60 cm could improve the trap efficacy and can be used for monitoring ambrosia beetles in pecan orchards.

期刊介绍: Insects (ISSN 2075-4450) is an international, peer-reviewed open access journal of entomology published by MDPI online quarterly. It publishes reviews, research papers and communications related to the biology, physiology and the behavior of insects and arthropods. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
