Helicoverpa
''Helicoverpa'' is a genus of moths in the family Noctuidae first described by David F. Hardwick in 1965. Some species are among the worst Lepidopteran agricultural pests in the world, and three species (''H. armigera'', ''H. zea'', and ''H. punctigera'') migrate long distances both with and without human transportation, mixing resistance alleles along the way.

Helicoverpa Zea
''Helicoverpa zea, ''commonly known as the corn earworm, is a species (formerly in the genus ''Heliothis'') in the family Noctuidae. The larva of the moth ''Helicoverpa zea'' is a major agricultural pest. Since it is polyphagous (feeds on many different plants) during the larval stage, the species has been given many different common names, including the cotton bollworm and the tomato fruitworm. It also consumes a wide variety of other crops. The species is widely distributed across the Americas with the exception of northern Canada and Alaska. It has become resistant to many pesticides, but can be controlled with integrated pest management techniques including deep ploughing, trap crops, chemical control using mineral oil, and biological controls. The species migrates seasonally, at night, and can be carried downwind up to 400 km. Pupae can make use of diapause to wait out adverse environmental conditions, especially at high latitudes and in drought. Distribution ...

Helicoverpa Punctigera
''Helicoverpa punctigera'', the native budworm, Australian bollworm or ''Chloridea marmada'', is a species of moth in the family Noctuidae. This species is native to Australia. ''H. punctigera'' are capable of long distance migration from their inland Australian habitat towards coastal regions and are an occasional migrant to New Zealand. This species is a generalist, with larvae observed feeding on at least 100 plant species, and are considered a pest for tobacco, flax, peas, sunflower, cotton, maize, tomatoes and other crops. Outside of agricultural settings, primary host plants include some Australian native daisies, in particular flat billy buttons ''Leiocarpa ''Leiocarpa'' is a genus of plants in the family Asteraceae The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales.
