In Western Australia, researchers discovered a wild tobacco species that kills insects, reports Mongabay.

The tobacco plant is covered with sticky hairs on which flies, mosquitoes and aphids met an untimely death. After taking the seeds to the greenhouses at Kew Gardens in London to cultivate them, scientists found that the second generation continued its murderous ways on foreign soil, making it the first wild tobacco species reported to kill insects.
The tobacco, previously unknown to science, has been named Nicotiana insecticida. Its description was published in the journal Curtis’s Botanical Magazine.
“Nicotiana insecticida demonstrates well the adage that ‘tobacco kills’,” Mark Chase, a scientist at the Royal Botanic Gardens, Kew, said in a press release, “although in this case it is insects that become ensnared on its sundew-like glandular hairs and die”.
The new tobacco does not appear to be carnivorous, but rather uses its sticky hairs to trap insects and protect itself from being eaten. The sticky tobacco is one of seven species of Nicotiana (wild tobacco) newly named by scientists from the Royal Botanical Gardens, Kew, Australia’s Curtin University, and the University of Vienna, the report said. “The arid parts of Australia, which is most of the continent, have been thought of as almost barren with limited plant diversity, but in recent years these poorly studied areas have yielded many new and unusual species,” Chase said in a press release.
Along the salt lakes between the Western Australian wheat belt and the dry central region, scientists found Nicotiana salina (salty tobacco), and in the Northern Territory, Nicotiana walpa, named from the local Aboriginal word for wind (in Pitjantjatjara, the language of the Anangu people).
“The fact that we have only now found [these species],” Chase told Mongabay, “means that there are probably a lot more similarly interesting species out there to be found.”
