Where do thrips pupate?

Where do thrips pupate?

• A. In the soil.
• B. In the petals of flowers.
• C. On leaf surfaces.
• D. Inside plant stems.

Answer: (A)

Thrips have a nonfeeding pupal stage that develops in a protected environment. In ornamental and turf settings, that protection is most often the soil (or leaf litter at the plant base). After the larval stages feed, they molt into prepupae and pupae and stay hidden in moist soil where they can mature into adults. This underground pupation is why you’ll commonly find thrips emerging from the soil rather than from flowers or stems. Maintaining good soil hygiene, such as removing plant debris and reducing excessive mulching, can help reduce the pupal population. Pupation on petals, leaf surfaces, or inside stems isn’t typical because the pupal stage doesn’t feed and needs the protective environment that soil provides.
