Onion Thrips (Thrips tabaci)
Thrips species attacking onions, leeks and salads, causing silver streaks and reduced yield.
Onion thrips (Thrips tabaci) attack leeks, onions, salad crops and ornamentals. Feeding causes pale streaks, silvering and corky patches on leaves and bulbs. Damage reduces photosynthesis and can make crops unmarketable. Biological control includes predatory mites such as Amblyseius swirskii and ground-dwelling predators in the crop environment, combined with reflective mulches and weed management.
