The cotton bollworm is very variable in both size and colour.

The female cotton bollworm can lay several hundred eggs, distributed on various parts of the plant.

The cotton bollworm is a highly polyphagous species.

When the larva consumes cotton, it is known as the cotton bollworm.

In the US and India, pheromone traps are being used to study the movement of the cotton bollworm.

The cotton bollworm causes enormous losses.

The product has been used to destroy the eggs and larvae of the tobacco budworm and the cotton bollworm.

Cotton bollworm may refer to:

Elcar, a virus product by Sandoz Ltd. that was marketed to attack the cotton bollworm in the 1970's, never became a big seller.

'Helicoverpa armigera', a close relative of 'H. zea', is a major cotton bollworm in Asia.

The larvae are pests for cotton or tobacco growers as the cotton bollworm or tobacco budworm.

Helicoverpa zea (Cotton Bollworm)

For example, the cotton bollworm, a common cotton pest, feeds on Bt cotton it will ingest the toxin and die.

Elsewhere there is renewed enthusiasm for rearing Trichogramma, a small wasp which parasitises the eggs of many species, such as Heliothis, the cotton bollworm.

Cotton bollworm, Helicoverpa armigera, and native budworm, Helicoverpa punctigera, are caterpillars that damage cotton crops.

All cotton may be treated with insecticides (excluding foliar Bt products) labeled for control of the tobacco budworm, cotton bollworm, or pink bollworm.

About 25 Texas farmers have joined to sue the companies for losses from cotton bollworm damage on more than 18,000 acres planted last year with genetically engineered Bollgard varieties that produce their own insecticides.

However, recently cotton bollworm has been developing resistance to Bt cotton and the Indian Agriculture Ministry linked farmers' suicides in India to the declining performance of Bt cotton for the first time.

According to an article published in Science Daily, researchers have found that members from a cotton bollworm species, Helicoverpa zea, were Bt resistant in some crop areas of Mississippi and Arkansas during 2003 and 2006.

Until now the industry has subsisted on variations of two main products: soybeans and other crops resistant to Monsanto's Roundup herbicide, and BT corn and cotton, which are resistant to the corn borer and the cotton bollworm, respectively.

This program, along with the introduction of genetically engineered Bt cotton (which contains a bacterial gene that codes for a plant-produced protein that is toxic to a number of pests such as cotton bollworm and pink bollworm), has allowed a reduction in the use of synthetic insecticides.

The cotton bollworm, corn earworm or Old World (African) bollworm, Helicoverpa armigera, (also known as the scarce bordered straw in the UK, where it is an immigrant) is a moth, the larvae of which feed on a wide range of plants, including many important cultivated crops.

The corn earworm is found in temperate and tropical regions of the world.

Helicoverpa zea, an agricultural pest also known as the "corn earworm"

When it consumes corn, it is known as the corn earworm.

Corn earworm may refer to:

Corn earworm (Helicoverpa zea)

The corn earworm is considered to be a major agricultural pest, with a large host range encompassing not only corn, but also numerous other crop plants.

Larvae feed on the Noctuid moth, other common hosts include the Tomato fruitworm, corn earworm, and cutworms.

Pesticides are one method by which corn earworm populations are controlled; however, since they have been widely used, the insects are resistant to many pesticides.

The flowers are eaten by the larvae of the corn earworm, Helicoverpa zea and the cabbage looper, Trichoplusia ni.

Orius insidiosus, the "insidious flower bug", for example, feeds on the eggs of the corn earworm (Helicoverpa zea).

The corn contains a bacterial gene that produces a toxin making the corn resistant to the corn borer and the corn earworm.

Extracts of the fruit bodies are toxic to the corn earworm, Heliothis zea and the large milkweed bug, Oncopeltus fasciatus.

The larvae of the Noctuidae genus Spodoptera (armyworms) and Helicoverpa (corn earworm) can cause extensive damage to certain crops.

The Chilean Corn Earworm (Helicoverpa atacamae) is a moth of the Noctuidae family that is endemic Chile.

Entomologists have learned to mimic mating pheromones for moths, such as the corn earworm, and beetles, such as the japaneese beetles, to aid in trapping pest insects.

Extracts using hexane of freshly harvested flowers of S. acmella were bioassayed against Aedes aegypti (yellow fever mosquito) larvae and Helicoverpa zea (the corn earworm moth) neonates.

They just look concerned (like maybe you should see a therapist) when you start talking about how coriander is supposed to repel the Colorado potato beetle, and that cosmos planted next to corn may deter the corn earworm.

Reported prey include the larvae of Mexican bean beetle, European corn borer, diamondback moth, corn earworm, beet armyworm, fall armyworm, cabbage looper, imported cabbageworm, Colorado potato beetle, velvetbean caterpillar, and flea beetles.

Pests that attack this crop include the powdery mildew fungus Erysiphe pisi, the pea aphid Acyrthosiphon pisum, the corn earworm (Heliothis zea), the fall armyworm (Spodoptera frugiperda), and spider mites of genus Tetranychus.

This bug, Podisus maculiventris, eats more than 100 kinds of destructive garden pests, including the gypsy moth caterpillar, the birch leafminer, the Colorado potato beetle, the Mexican bean beetle, the tomato fruitworm, the corn earworm, the onion maggot and the cabbage looper.

The cotton bollworm, corn earworm or Old World (African) bollworm, Helicoverpa armigera, (also known as the scarce bordered straw in the UK, where it is an immigrant) is a moth, the larvae of which feed on a wide range of plants, including many important cultivated crops.

The corn earworm moth, whose hungry larvae can decimate an otherwise healthy crop, has antennae tuned to these as well as other specific frequencies, with the result that when the female flies about on a clear moonlit night, she 'sees'- through her antennae - the whole field lit up, like an array of a myriad natural light bulbs.

This variety was designed to give the plant resistance against lepidopteran insects like the brinjal fruit and shoot borer (Leucinodes orbonalis) and fruit borer (Helicoverpa armigera).
