3 Corresponding author: [email protected] ABSTRACT: We compared the native bees visiting the flowers of three species of invasive plants, saltcedar (Tamarix spp.) and white and yellow sweet clover (Melilotus albus, M. officinalis), with those visiting seven concurrently blooming native plant species in mid-summer at three sites in Capitol Reef National Park, Utah. Overall, as many total s...

Many invasive species show allelopathic effects that contribute to competitive impacts on native vegetation for which few control measures exist. We investigated the potential pyrolized organic material used as a soil amendment (“biochar”) sorb allelochemicals and mitigate seed germination early seedling development in three common plants Canada: garlic mustard (Alliaria petiolata), tree of hea...

In the conditions of a small-scale experiment on natural infectious background (Belgorod, Russia), threefold excess CFU values rhizosphere Melilotus officinalis was revealed in comparison with fallow soil, but abundance typical species and control 63% 77%, respectively. The Jacquard coefficient proved high similarity mycocomplexes M. (33%). core microcomplex sweet clover is Trichoderma lignorum...

Diaphorina citri Kuwayama (Psyllidae: Hemiptera) and Aphis gossypii Glover (Aphididae; are destructive sap-feeding pests of citrus cotton, respectively. This study assessed the toxicity potential indigenous flora Soon valley surrounding salt range (Punjab, Pakistan) against D. A. gossypii. Among acetone extracts 40 plant species, Mentha longifolia (L.) Huds., Melilotus officinalis Pall., Nerium...

Two new p-hydroxybenzoic acid glycosides, namely p-hydroxybenzoic acid-4-O-α-d-manopyranosyl-(1 → 3)-α-l-rhamnopyranoside (compound 1) and 4-O-α-l-rhamnopyran-osyl-(1 → 6)-α-d-manopyranosyl-(1 → 3)-α-l-rhamnopyranoside (compound 2), and seven known compounds, compound 3, 6, 7 (acid components), compound 8, 9 (flavonoids), compound 4 (a coumarin) and compound 5 (an alkaloid), were isolated from ...

Effects of temperatures on the host-parasite relationships were studied for three legume species and four populations of root-knot nematodes from the western United States. The nematode populations were Meloidogyne hapla from California (MHCA), Utah (MHUT), and Wyoming (MHWY), and a population of M. chitwoodi from Utah (MCUT). The legumes were milkvetch (Astragalus cicer), alfalfa (Medicago sat...

During the study, it was found that an increase in dose of sweet yellow clover extract from 0.5 to 2.5 mg/kg live weight per day contributed number of: hemoglobin by 1.83 g/l (1.79%), leukocytes 0.14 thousand 109/l (2.34%), total protein blood serum sheep 0.43 (0.7%), glucose 0.18 mmol/l (4.19%), calcium (5.32%), phosphorus only 0.08 mg/100 ml (1.6%), 220 g (2.18%). In control group, two out si...
