Abstract

BACKGROUND

Several traps are recommended for monitoring corn earworm, Helicoverpa zea (Boddie), an important pest of field, vegetable and fruit crops in the U.S. These traps, which are meant to capture H. zea in many cases end up capturing other insects. Helicoverpa zea has recently been found feeding on different seeds and dual-type (seed and fiber) hemp, Cannabis sativa L. (Rosales: Cannabaceae) causing serious damage. Limited work has been done on developing integrated pest management (IPM) for H. zea industrial hemp in Missouri.

METHODS

We evaluated the attractiveness of different traps with the aim of developing a monitoring system for the adult male H. zea in industrial hemp fields in two Missouri locations. In addition, we recorded other non-target insects in the traps to determine trap selectivity. Commercially available green, clear, tricolor bucket traps Heliothis Scentry and Scentry Delta 1X traps baited with H. zea sex pheromones were evaluated in 2021 and 2022.

RESULTS

Tricolor traps captured significantly more adult male H. zea than the other traps in both years. Non-target insects, mainly Xylocopa virginica (L.) (Hymenoptera: Apidae), Bombus spp. (Hymenoptera: Apidae), and Apis mellifera L. (Hymenoptera: Apidae) were also captured. The tricolor trap captured the most bees.

CONCLUSIONS

The presence of non-target species highlights the risk of using tricolor traps as a monitoring tool. This data provides information for planning the monitoring of corn earworm in industrial hemp farms in Missouri.

摘要

背景

在美国，有几种诱捕器被推荐用于监测玉米穗虫，即棉铃虫（Helicoverpa zea (Boddie)），它是田间、蔬菜和水果作物的重要害虫。这些诱捕器旨在捕获棉铃虫，但在很多情况下最终捕获的却是其他昆虫。最近发现棉铃虫以不同的种子以及双用途（种子和纤维）大麻，即大麻（Cannabis sativa L.，蔷薇目：大麻科）为食，造成了严重损害。在密苏里州，针对工业大麻中棉铃虫的综合虫害管理（IPM）开展的工作有限。

方法

我们评估了不同诱捕器的吸引力，目的是为密苏里州两个地点的工业大麻田中的成年雄性棉铃虫开发一种监测系统。此外，我们记录了诱捕器中的其他非目标昆虫，以确定诱捕器的选择性。2021年和2022年对用棉铃虫性信息素诱饵的市售绿色、透明、三色桶式诱捕器Heliothis Scentry和Scentry Delta 1X诱捕器进行了评估。

结果

在这两年中，三色诱捕器捕获的成年雄性棉铃虫明显多于其他诱捕器。还捕获了非目标昆虫，主要是木匠蜂（Xylocopa virginica (L.)，膜翅目：蜜蜂科）、熊蜂属（Bombus spp.，膜翅目：蜜蜂科）和意大利蜜蜂（Apis mellifera L.，膜翅目：蜜蜂科）。三色诱捕器捕获的蜜蜂最多。
