We’ve been experimenting with using Nicotiana bethamiana instead of yellow sticky traps in our greenhouse. Works pretty well!


One of our student researchers stumbled upon a paper about N benthamiana's use as a dead-end pest trap. The nicotine the plant produces kills bugs, and it also produces volatiles that attract the pests. They've been most effective with whitefly, but I've also seen thrips get caught in our other rooms.

Less plastic, more tobacco relatives!

    Pretty cool idea, Pinguicula sp. can be used for the same purpose. Since N. bethamiana is easily transformed, genetic engineering could make it more effective. I have seen fungal gnats get caught on Solanum berthaultii leaves, but trips were unfazed.
