Effect of modified meridic diet on the development and growth of tomato fruitworm
Helicoverpa armigera (Lepidoptera: Noctuidae).
Bacillus thuringiensis for control of tomato fruitworm. Proc.
Treatment decisions based on eggs scouting for tomato fruitworm, Helicoverpa zea (Boddie), reduce insecticide use in tomato.
Evaluation of Resistance to Beet Armyworm and Tomato Fruitworm
Ten-plant plots were divided into five parts consisting of the first border plant, two plants inoculated with beet armyworm eggs, four uninoculated plants, two plants inoculated with tomato fruitworm eggs, and the second border plant.
The best characterized of these newly discovered polydnaviruses is one associated with Campoletis sonorensis, a less than half-inch long wasp that attacks two larvae -- the tobacco budworm and another that's variously known as the cotton bollworm, tomato fruitworm
or corn earworm.
Morgan at the ARS Biocontrol of Insects Research Laboratory in Columbia, Missouri, focus on the corn earworm, which is also known as the cotton bollworm and tomato fruitworm
. The corn earworm Helicoverpa zea, formerly Heliothis zea, and the related tobacco budworm, Heliothis virescens, are blamed for nearly $2 billion in damages annually to important agricultural crops.
zea - variously known as the corn earworm, tomato fruitworm
, and cotton bollworm - costs growers about $1.5 billion in damage and control measures each year.
Armyworms, cabbageworms, corn earworms, diamondback moths, grape leaf rollers, melon worms, tomato fruitworms
, tomato hornworms, and various webworms and budworms are candidates for Bt treatment.
Midwesterners call the insects corn earworms, but farmers elsewhere grumble about cotton bollworms and tomato fruitworms
Elliger have found that varieties of Physalis (a genus including the tomatillo and cape gooseberry) and of petunia contain chemicals that can dramatically stunt Heliothis zea -- also known, depending on the host, as tomato fruitworms
, corn earworms or bollworms.
