"Impact of fou rinsecticides on Japanese Beetle (Coleoptera: Scarabaeidae) Egg Predators and White Grubs in Turfgrass - Field experiments were conducted to measure the effects of four commonly used turfgrass insecticides (isofenphos, diazinon, imidacloprid, halofenozide) on white grubs (Coleoptera: Scarabaeidae) and ant predators of white grub eggs. Ant populations were measured over time with canned tuna, whereas predation by the ants was measured with artificially placed Japanese beetle, Popillia japonica Newman, eggs. The effectiveness of each insecticide at controlling Japanese beetle grubs, when applied at different times during the growing season, was also measured. Isofenphos and diazinon significantly reduced both ant numbers and white grub egg predation, whereas imidacloprid and one halofenozide treatment did not significantly impact either measurement. A second halofenozide treatment significantly reduced white grub egg predation. Isofenphos and diazinon were ineffective at controlling Japanese beetle grubs when applied in June but were highly efficacious when applied in August. Evidence of enhanced biodegradation was found in plots that received both June and August applications of diazinon. Both June and August applications of imidacloprid and halofenozide provided good control of white grubs." https://academic.oup.com/jee/article-abstract/94/1/145/2217394

"Red Imported Fire Ant Influences on White Grub Populations and Soil Foraging Characteristics in Managed Turfgrass - White grubs (Coleoptera: Scarabaeidae) are a significant pest of managed turfgrass throughout the United States and are difficult to monitor because of their subterranean habitat. Recent reports have stated that white grubs are becoming an increasing problem in southern turfgrass. Selective removal of common turfgrass ants using labeled insecticides can cause localized outbreaks of turfgrass pest. However, white grubs and other hypogeal insects are reported to escape predation of Solenopsis invicta (Buren) and seemingly co-exist in close proximity. After two years of field experiments examining interactions between S. invicta and white grubs, as well as examining this ant’s soil foraging characteristics, it was found that the control of S. invicta has no influence on white grub populations in turfgrass. Further investigation showed S. invicta does not forage within the soil for prey as previous research on other common turfgrass ants suggests. Experimental design flaws identified and addressed during this research highlights factors affecting previous studies on ant predation of subterranean pests that likely resulted in biased data." http://etd.auburn.edu/handle/10415/2569

"Contrary to other studies, results presented here suggest that fire ants and fire ant control products applied to turfgrass have a minimal impact on white grub populations." https://pubmed.ncbi.nlm.nih.gov/22299364/
