Integrating biological and chemical controls in decision making: European corn borer (Lepidoptera: Crambidae) control in sweet corn as an example.
As growers switch to transgenic crops and selective insecticides that are less toxic to natural enemies, natural enemies can become more important in agricultural pest management. Current decision-making guides are generally based on pest abundance and do not address pest and natural enemy toxicity differences among insecticides or the impact of natural enemies on pest survival. A refined appro...
متن کاملProcessing of Sweet Corn
Sweet corn cobs constituting raw material for processing must be characterized by the highest quality of kernels. Kernel quality is defined not just by the chemical and sensory properties, but also by the mechanical parameters of kernels. This appears to fully justify joint consideration of all those properties. Sweet corn is probably a mutant of fodder corn (Orłowski, 2000). Significant differ...
متن کاملImprovement of Sweet Corn
L HE only genetic difference between the composition of a sweet corn kernel and that of field corn is due to a single recessive gene out of the hundreds or thousands of genes in corn. This gene makes the sugary condition of the kernel persist in sweet corn; or, in other words, prevents the conversion of some of the sugar into starch. The first recorded observation of sweet corn by w^hite men ap...

متن کاملMulti-state trials of Bt sweet corn varieties for control of the corn earworm (Lepidoptera: Noctuidae).
Field tests in 2010-2011 were performed in New York, Minnesota, Maryland, Ohio, and Georgia to compare Bt sweet corn lines expressing Cry1A.105 + Cry2Ab2 and Cry1Ab with their non-Bt isolines, with and without the use of foliar insecticides. The primary insect pest in all locations during the trial years was Heliocoverpa zea (Boddie), which is becoming the most serious insect pest of sweet corn...
