(Helicoverpa zea) herbivory on corn is costly in terms of the lack of crop yield and the high amount of economical damage.
Evaluation of transgenic sweet corn hybrids expressing CryIA(b) toxin for resistance to corn earworm
and fall armyworm (Lepidoptera: Noctuidae).
In the corn earworm
(Helicoverpa zea) and other crop pests, the hormone has been shown to break diapause, essentially waking up the bugs from their pupal state after they have bean protectively burrowed underground during cold weather.
This technology offers the same refuge management benefits as Genuity SmartStax RIB Complete but provides protection against above ground pests, including corn earworm
Each trap was baited with Hercon Zealure Luretape (Hercon Environmental, Emigsville, Pennsylvania), a high-quality synthetic pheromone lure designed to attract male corn earworm
moths (Gauthier et al.
1984) and corn earworm
, Helicoverpa zea (Boddie) (Drapek et al.
SMOTHER CORN EARWORM
To prevent damage, use a medicine dropper to slip two drops of mineral oil inside the tip of each ear, three to seven days after silks appear.
Furthermore, control of certain insect pests by corn producing the Bt toxin Cry1Ab may have conferred a competitive advantage to the western corn earworm
(Striacosta albicosta), a pest that is not affected by this Bt toxin (Dorhout and Rice 2010).
Incidentally, geranium budworm is quite similar to corn earworm
, a pest that has been known to gobble up ears of corn in certain Valley gardens.
Identification of molecular markers linked to quantitative trait loci for soybean resistance to corn earworm
(Heliothis zea (Boddie)) normally a late season pest, did not develop during 2004.
Evidences for a far infrared (FIR) electromagnetic theory of communication and sensing in moths and its relationship to the limiting biosphere of the corn earworm
, Heliothis zea.
