Gossypium is a genus of flowering plants in the tribe Gossypieae of the mallow family, Malvaceae, from which cotton is harvested. It is native to tropical and subtropical regions of the Old and New Worlds. There are about 50 Gossypium species, making it the largest genus in the tribe Gossypieae, and new species continue to be discovered. The name of the genus is derived from the Arabic word goz, which refers to a soft substance.
Helicoverpa zea, commonly known as the corn earworm, is a species in the family Noctuidae. The larva of the moth Helicoverpa zea is a major agricultural pest. Since it is polyphagous 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 Gelechiidae are a family of moths commonly referred to as twirler moths or gelechiid moths. They are the namesake family of the huge and little-studied superfamily Gelechioidea, and the family's taxonomy has been subject to considerable dispute. These are generally very small moths with narrow, fringed wings. The larvae of most species feed internally on various parts of their host plants, sometimes causing galls. Douglas-fir (Pseudotsuga) is a host plant common to many species of the family, particularly of the genus Chionodes, which as a result is more diverse in North America than usual for Gelechioidea.
Bollworm is the common term for a moth larva that attacks the fruiting bodies of certain crops, especially cotton. The most common moths known as bollworms are:
The pink bollworm is an insect known for being a pest in cotton farming. The adult is a small, thin, gray moth with fringed wings. The larva is a dull white caterpillar with eight pairs of legs with conspicuous pink banding along its dorsum. The larva reaches one half inch in length.
Bt cotton is a genetically modified organism (GMO) or genetically modified pest resistant plant cotton variety, which produces an insecticide to combat bollworm.
The cotton bollworm, corn earworm, or Old World (African) bollworm is a moth, the larvae of which feed on a wide range of plants, including many important cultivated crops. It is a major pest in cotton and one of the most polyphagous and cosmopolitan pest species. It should not be confused with the similarly named, related species Helicoverpa zea.
Maurice James Lukefahr, a pioneer researcher in the fields of host plant resistance and environmental control of cotton insect pests, died in Elsa, Texas in 2002.
Pectinophora is a genus of moths in the family Gelechiidae. Perhaps the best known species is the pink bollworm, Pectinophora gossypiella (Saunders). P. gossypiella is one of the world's most destructive insect pests that causes terrible damage to cotton bolls. The larvae (caterpillars) bore into the bolls, causing them to fall or the blossoms to fail to open. The larvae tunnel through the immature lint and into the seeds eating them. As a result the lint may be unpickable or so stunted as to greatly lower the yield and grade. The yield of oil from the seeds is greatly reduced. Double seeds are found when the cotton is gained, two partly eaten seeds being fastened together.
Anomis flava, the cotton looper, tropical anomis or white-pupiled scallop moth, is a moth of the family Erebidae. The species was first described by Johan Christian Fabricius in 1775. It is found in large parts of the world, including China, Hawaii, São Tomé and Príncipe, the Society Islands, Thailand, New Zealand, and Australia. Subspecies Anomis flava fimbriago is found in North America.
A pheromone trap is a type of insect trap that uses pheromones to lure insects. Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure, as the red rubber septa in the picture, is encased in a conventional trap such as a bottle trap, Delta trap, water-pan trap, or funnel trap. Pheromone traps are used both to count insect populations by sampling, and to trap pests such as clothes moths to destroy them.
Earias insulana, the Egyptian stemborer, Egyptian bollworm, spiny bollworm or cotton spotted bollworm, is a moth of the family Nolidae. The species was first described by Jean Baptiste Boisduval in 1833. It is found in most of Africa, southern Europe, the Near East and Middle East, Japan, Taiwan, the Philippines, Australia and Hawaii. It is a rare in immigrant in Great Britain.
Herpetogramma licarsisalis, the grass webworm or pale sod-webworm, is a moth of the family Crambidae. It is native to most of the old world tropics, including New Zealand, Hong Kong and Queensland. It is an introduced species in many other parts of the world, including Hawaii and the Canary Islands, as well as India and Sri Lanka
Decatopseustis cataphanes is a moth of the family Gelechiidae. It was described by Ian Francis Bell Common in 1958. It is found in Australia, where it has been recorded from the Australian Capital Territory.
Pectinophora endema is a moth of the family Gelechiidae. It was described by Ian Francis Bell Common in 1958. It is found in Australia, where it has been recorded from Queensland and New South Wales.
Hartford Hammond Keifer was a world authority on eriophyid mites. Based in California, he initially studied the local microlepidoptera before turning to mites in 1937.
Diparopsis castanea is the type species of the genus Diparopsis: moths in the family Noctuidae; no subspecies are listed in the Catalogue of Life. This is known as the red bollworm, which is a significant pest of cotton crops in Eastern and Central-Southern Africa.
Earias fabia, called the cotton spotted bollworm as a larva, is a moth of the family Nolidae. The species was first described by Caspar Stoll in 1781. It is sometimes included in the species Earias vittella.
Acanthaspis quinquespinosa is a species of assassin bug found in India, Sri Lanka, Myanmar, Nepal and Tibet. It is a predator, and both nymphs and adults feed on termites, beetles, caterpillars and other insect prey.
