This paper describes the morphology and behavior of the immature stages of Oleria baizana (Haensch) (Lepidoptera: Nymphalidae) from northeastern Ecuador. Brugmansia aurea Lagerh. (Solanales: Solanaceae) is the larval food plant. Eggs are laid singly, off of the host plant in the leaf litter. During the night, larvae climb a food plant seedling and sever a leaf petiole, parachuting with the leaf...

In zooxanthellate corals, the photosynthetic fixation of carbon dioxide and the precipitation of CaCO3 are intimately linked both spatially and temporally making it difficult to study carbon transport mechanisms involved in each pathway. When studying Tubastrea aurea, a coral devoid of zooxanthellae, we can focus on carbon transport mechanisms involved only in the calcification process. We perf...

The chemical composition of Matricaria chamomilla L. and Nepeta cataria L. essential oils was determined by GC-MS on an apolar stationary phase by comparison of the characteristic fragmentation patterns with those of the Wiley 275L database. The GC-MS chromatograms were compared with those obtained by fast GC equipped with a direct resistively heated column (Ultra Fast Module 5% phenyl, 5 mx 0....

Weed infestations and associated yield losses require effective weed control measures in soybean and sugar beet. Besides chemical weed control, mechanical weeding plays an important role in integrated weed management systems. Field experiments were conducted at three locations for soybean in 2013 and 2014 and at four locations for sugar beet in 2014 to investigate if automatic steering technolo...

The Oriental species of Apsilocera Bouček, 1956 (Hymenoptera: Pteromalidae) are revised and the limits of the genus are reevaluated. Bulolosa Bouček, 1990 and Kratinka Bouček, 1988 are treated as synonyms of Apsilocera, syn. n. Bulolosa bidens Bouček and Kratinka brevis Bouček are transferred to Apsilocera as A. bidens (Bouček) and A. brevis (Bouček) comb. n., respectively. Twelve new species (...

BACKGROUND This study investigated the extent of traditional knowledge and use of homemade herbal remedies for livestock by farmers in 3 Swiss cantons (Aargau, Zurich, Schaffhausen). The study focused on organic farms. METHODS At 21 farms, 24 farmers aged 36-83 years were interviewed with a semi-structured, detailed questionnaire. For each homemade herbal remedy, the plant species, mode of pr...
