Influence of sticky card color and tree species on three parasitoid genera of Halyomorpha halys (Hemiptera: Heteroptera)

Halyomorpha halys (Hemiptera: Pentatomidae), or brown marmorated stink bug, is an invasive species in the U.S. that causes significant economic damage to a diversity of crops. Biological control by egg parasitoids is a promising measure that needs further research. Accurate sampling for parasitoid activity is critical for assessment of the impact of multiple genera of egg parasitoids shown to be associated with H. halys. To test color and tree species preference of three parasitoid genera (Anastatus, Trissolcus, Telenomus), different colored sticky cards were placed on three species of trees. We found that the three parasitoid genera appeared to have preference for yellow and green sticky cards over blue and red. Parasitoids appeared to have preferences in tree species, but their preference varied for each species. Results suggest that Anastatus may prefer green sticky cards and cherry trees, however more research should be done to support this finding.USDA National Institute of Food and Agriculture (NIFA), Shrewsbury La

Pollinator Plants for Stormwater Management

Final project for PLSC 460: Application of Knowledge in Plant Science (Spring 2021). University of Maryland, College Park.The group of students provided recommendations to M-NCPPC Parks to develop a pollinator plant selection guide for three stormwater management facilities: a parking lot island, a building foundation planting, and an open field. The selection guide included site information for three types of plantings (proper use of stormwater control measures and viewpoints) and plant use facts (environmental metrics and other characteristics) and pictures.Prince George's County Department of Parks & Recreation (PGDPR
