The web contents of two spider species were found to have high numbers of A. diaperinus adults in Brazil (Rossi and Godoy 2005). Rossi and Godoy (2005) suggest that natural predation by spiders in poultry houses should be quantified in further studies for use in combination with other biological control agents. Geden and Hogsette (1994) recommend that additional surveys of beetle populations both in the United States and in the original home range of the lesser mealworm should be conducted to discover novel biological control agents.
