Investigating biocontrol options for the industry is always important, given the lack of registered insecticides in this country. Currently, the industry is relying heavily on two closely related chemicals – Beleaf (flonicamid) and Endeavor (pymetrozine) – for control of the foxglove aphid (Aulacorthum solani). If the battle with thrips (and Bemisia whitefly) has taught anything, it’s to be prepared for chemical failure.
Unfortunately, biological control of foxglove aphid has been challenging so far. For example, Sarah Jandricic' research showed that Aphidoletes, a “generalist” aphid predator, actually has lower preference for foxglove aphid than other species, and is less effective for this pest. However, a long-term project by Dr. Michelangelo La-Spina (VRIC) has found some results that get us closer to being able to control foxglove aphid without resorting to pesticide sprays.
One way you can help move this research forward is by filling in this quick, 10 question survey if you’re a grower (even if you’ve never had problems with foxglove aphid before).
Read on for more details on exactly what Dr. La-Spina has found.
