The Effect of Western Corn Rootworm (Coleoptera: Chrysomelidae) and Water Deficit on Maize Performance Under Controlled Conditions

摘要: The western corn rootworm, Diabrotica virgifera LeConte, is the most important insect of maize, Zea mays L., but knowledge its interaction with water deficit on maize production lacking. A series greenhouse experiments using three infestation levels D. virgifera, under well-watered, moderately dry, and very dry soil moisture were conducted to quantify rootworm B73×Mo17 growth physiology. Three separate conducted. Soil regimes initiated 30 d postplanting for neonate second-instar larvae 30 d postinfestation in experiment eggs. In experiments, there no significant differences among their effects leaf potential, shoot weight, root weight. significantly impacted larval recovery experiment, other interactions documented between levels. Overall, results indicate that conditions these effect was much greater plants than minimally affected measured parameters plant performance.
