Development of Pest Management Thresholds and Management Strategies for the Invasive Brown Marmorated Stink Bug, Halyomorpha halys (Stål): (Pentatomidae) In Commercial Tree Fruit in the Hudson Valley of NY.

Date: 

2015 to 2017

Summary: 

This study developed a simple and effective method for using BMSB monitoring tools as a trigger to initiate pest management. Management strategies to determine the most effective and least labor-intensive method for employing pest monitoring and management were recommended and tested in the field. Trapping assessments of populations employed multiple lure formulations in boarder traps, attract and kill strategies and passive trapping to determine presence and density. Evaluations of the efficacy of pest management tools labeled for BMSB were conducted in field trials both in small plots and in grower orchards.

Issue: 

The brown marmorated stink bug Halyomorpha halys (Stål) (BMSB), is a newly invasive pentatomid insect, native to Asia. It is an arboreal insect, predominately residing and feeding in deciduous forests. Over the past 10 years it has become well established in Mid-Atlantic States, residing in over 37 states throughout the US, now resident in 33 counties in New York State. The BMSB has a uniquely different host range from native stink bugs, feeding on a wide variety of landscape, ornamental and agricultural commodities. It has been found to feed on over 300 plant hosts, with preference toward agricultural crops such as apple and pears, grape, peaches, cherry, raspberries, sweet corn, tomato, peppers, green beans, lima beans and soybeans. In 2012 the first assessment of economic injury was reported in NY, in which BMSB caused extensive damage to tree fruit on three farms in Ulster and Orange County. Late season varieties of Red Delicious, Golden Delicious and Pink Lady were assayed for feeding injury. Damage across all three sites was in excess of 21% loss.

Response: 

1. Using BMSB trap data from statewide cooperators and those used in this study, we developed statewide mapping of BMSB populations showing field presence, applying threshold levels developed by USDA (> 10 / trap) and visual economic injury. Maps were posted for on-demand Internet accessibility displayed for producers to quickly determine the presence and activity of the insect across the state by county.
2. We monitored available host soil moisture and seasonal relative humidity to determine deciduous forest tree host viability correlated to BMSB tree fruit presence for incorporation into field recommendations.

3. Participating growers applied monitoring and threshold triggers to initiate pest management methods using efficacious insecticides to reduce damage caused by the stink bug complex.

4. CCE specialists generated BMSB regional trapping data to map the presence and density of BMSB in the region. Mapping updates were conducted by CCE and hosted by a cooperative partnership between the Hudson Valley Research Laboratory and the Early Detection & Distribution Mapping System web site developed by The University of Georgia - Center for Invasive Species and Ecosystem Health. (https://www.eddmaps.org/bmsbny/ ). Agricultural presence of BMSB will be displayed on a county wide basis, made available to growers on-demand through web based access.

5. Based on BMSB establishment in the 6 orchard sites participating in the study, BMSB pest alerts were generated and distributed to all pome fruit producers who are members of the Hudson Valley CCE. BMSB biology, developing presence, generational stages, keys to identification, pest management options and recommendations were included in the extension outreach.

6. The effectiveness of the active and passive trapping systems, determining the efficacy of application management and insecticide programs provided the necessary information producers required to select the appropriate tools needed to make essential management decisions for this insect upon the completion of the project.

Impact: 

Attract and Kill (ATK) solutions for agriculturally invasive insect pests are designed to reduce agricultural and urban pest populations whereby reducing pesticide loads in agricultural commodities and in the urban landscape. The use of ATK solutions for the invasive BMSB are developed using a pheromone, synergist and high intensity lighting for attraction of the insect in the fall during 2nd generation emergence. Adult BMSB fly onto woven polypropylene netting treated with insecticide, employed in commercial orchards and organic vegetable farms to reduce migration to crops, reduce the need for insecticide applications while lessening the impact on natural enemies.
