The data had been obtained during a period of peak migration of corn earworms
from fruiting corn fields.
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.
The type of resistance to corn earworm
is believed to be antibiosis.
The presence of high-quality plant parts (lima bean pods) reduced the number of prey (pea aphids and corn earworm
eggs) consumed by big-eyed bugs.
Plutellidae), obtained from the CPMRU colony; painted apple moth (Teia anartoides Walker, Lymantriidae), examined by authors DMS and SLW in New Zealand because of quarantine restrictions on transport of this Australian species to the US; corn earworm
(Helicouerpa zea (Boddie), Noctuidae), obtained from the CPMRU colony, and fall armyworm (Spodoptera frugiperda J.
We studied a relatively simple, agricultural system consisting of an omnivorous "predator," the big-eyed bug (Geocoris punctipes), two of its common prey species, pea aphids (Acyrthosiphum pisum) and eggs of the corn earworm
(Helicoverpa zea), and a shared host plant, lima beans (Phaseolus lunatus).
If corn earworms
have attacked yoursweet corn in the past, spray popcorn with Bacillus thuringiensis or carbaryl when silks first appear.
Diet: Asparagus beetles, caterpillars, Colorado potato beetles, corn earworms
, cutworms, slugs, squash vine borers and tobacco budworms.
Another potential benefit is staving off the ability of pests like corn earworms
to build tolerance to existing sources of resistance--such as that endowed by insecticidal proteins from the soil bacterium Bacillus thuringiensis, which is used in about 63 percent of U.
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
Other parasitic wasps include Aphytis melinus, which attacks red scale; Metaphycus helvolus, which attacks black scale; and several species of Trichogramma which parasitize the eggs of pest worms such as corn earworms
and cabbage worms.
