Impact of hilling timing on soybean gall midge (Diptera: Cecidomyiidae) abundance, plant injury, and yield.

ABSTRACT: In 2019, the soybean gall midge (Resseliella maxima Gagné) was identified as a new pest and species in the US Midwest, causing injury to soybean (Glycine max (L.) Merr.). Infestation of R. maxima in soybean starts with females laying eggs in the fissures or cracks that develop at the base of soybean at the V2 growth stage. These fissures can be found on soybean from the soil surface to the cotyledonary node. After eggs hatch, larvae feed inside the stem, leading to wilting and death of the plants. In 2021, hilling was tested as a cultural tactic at the V2 stage, where soil was placed at the base of stems covering the fissures, resulting in a reduction in soybean gall midge infestation. To better understand this cultural control practice, hilling was performed at different timings at differ
