Abstract Wireworms have become a significant menace to cereals in the Northern Great Plains. Therefore, research toward developing effective control methods such as biological with entomopathogenic nematodes (EPNs) is warranted. Two strains, each of two EPN species, Steinernema carpocapsae (Weiser) and riobrave Cabanillas, Poinar, Raulston form infected Galleria mellonella (L.) cadavers were ev...

Sucrose synthase (EC 2.4.1.13) of sugarbeet (Beta vulgaris L.) fibrous roots has a distinctly different order of preference for nucleoside diphosphate substrates than that of the taproot enzyme (Silvius, Snyder 1979 Plant Physiol 64: 1070-1073). Separation and quantitation of UDP, ADP, and GDP in root extracts by high-pressure liquid chromatography revealed that UDP levels in taproot tissue wer...

This paper presents a first analysis of MERIS-Full Resolution (FR) data to observe seasonal variations of the reflectances of agricultural fields in two regions with different climatic conditions: Toulouse (France) and Barrax (Castilla-La Mancha, Spain). The objective is to assess the capabilities of MERIS for crop monitoring. After applying an atmospheric correction method to the images we hav...

Corn (Zea mays, L.), bean (Phaseolus vulgaris L.), barley (Hordeum vulgare L.), spinach (Spinacia oleracea L.), and sugarbeet (Beta vulgaris L.) grown under iron deficiency, and Potamogeton pectinatus L, and Potamogeton nodosus Poir. grown under oxygen deficiency, contained less chlorophyll than the controls, but accumulated Mg-protoporphyrin IX and/or Mg-protoporphyrin IX monomethyl ester. No ...
