Chloridea virescens
Tobacco Budworm Moth, Tobacco Budworm
Chloridea virescens, the tobacco budworm moth, is a noctuid moth native to the Americas and a major agricultural pest. The species was transferred from genus Heliothis to Chloridea in 2013 based on genetic and morphological evidence. Adults are brownish with green tinge and distinctive wing banding. Larvae feed on buds, blossoms, and fruit of diverse host plants, causing significant crop damage. The species has developed rapid resistance to multiple insecticide classes, making management challenging.

Boston dart, drab cutworm
Euxoa bostoniensis, commonly known as the Boston dart or drab cutworm, is a noctuid moth species found in eastern and central North America. Adults have a wingspan of 40–45 mm and are active in May and again from September to October. The larvae are cutworms that feed on Nicotiana species, though the species occurs in areas where tobacco is not cultivated.
Lasioderma
cigarette beetles, tobacco beetles
Lasioderma is a genus of small beetles in the family Ptinidae, containing over 50 species as of 1990. The genus is best known for Lasioderma serricorne, commonly called the cigarette beetle or tobacco beetle, a major cosmopolitan pest of stored products. Members of this genus are associated with dried plant materials and have become distributed globally through human commerce. The genus has been variously classified in Anobiidae or Ptinidae depending on taxonomic treatment.
Lasioderma serricorne
cigarette beetle, tobacco beetle, cigar beetle, paprika beetle, tow bug, tobacco borer, cheroot beetle
Lasioderma serricorne is a small stored-product pest beetle, 2–3 mm in length, with a cosmopolitan distribution resulting from human commerce. It is distinguished from similar anobiid beetles by its uniformly serrated antennae lacking a terminal club, flatter thorax profile, and smooth elytra without grooves. The species has a remarkably broad diet, infesting tobacco, cereals, dried fruits, spices, and herbarium specimens. It possesses a mutualistic relationship with yeast-like symbionts (Symbiotaphrina spp.) that assist in protein metabolism and enable survival on nutritionally poor substrates. Strong flight capability and attraction to UV light facilitate its spread and monitoring.
Scrobipalpa
Scrobipalpa is a genus of small moths in the family Gelechiidae, established by Janse in 1951. The genus contains over 100 described species distributed across Africa, Asia, Europe, and introduced populations in North America and Australasia. Several species are economically significant agricultural pests, particularly of sugar beet, quinoa, tobacco, and eggplant. The genus was historically split with Euscrobipalpa treated as a subgenus or separate genus, but this distinction is no longer recognized as valid.
Trichobaris
flower weevils
Trichobaris is a genus of flower weevils in the family Curculionidae, comprising 8–13 described species distributed from the southwestern United States through Mexico. These weevils are specialized herbivores associated with plants in the family Solanaceae, particularly the genus Datura, with which they likely coevolved. Several species are notable agricultural pests, including T. mucorea (tobacco stalk borer) and T. trinotata (potato stalk borer), which also feed on cultivated solanaceous crops. Research on this genus has contributed to understanding host-herbivore coevolution, chemical ecology of host selection, and the decoupling of maternal oviposition cues from larval performance.
Tricorynus
deathwatch beetles, spider beetles
Tricorynus is a genus of beetles in the family Ptinidae, commonly known as deathwatch and spider beetles. The genus contains at least 80-90 described species. Members of this genus are associated with stored products and natural habitats involving dry organic materials. Some species, such as Tricorynus confusus, have been documented as pests in tobacco storage facilities.
