| [changes of phenols and lignin contents in alfalfa leaf damaged by odontothrips loti]. | in order to investigate the changes of secondary metabolites content of alfalfa induced by thrips odontothrips loti damaging, two alfalfa strains, one resistant to thrips (r-1) and the other susceptible to thrips (i-1) , were chosen to measure the phenols and lignin contents of alfalfa leaves under infestation with thrips at different densities (0, 1, 3, 5, 7 thrips x branch(-1), and 0 thrip x branch(-1) as control). after infestation 7 days, the polyphenols, tannin and condensed tannin contents ... | 2014 | 25223025 |
| [predation of orius minutus on odontothrips loti]. | in this paper, a laboratory study was made on the predation of orius minutus on the 3rd to approximately 4th instar nymphs of odontothrips loti, and the intraspecific interference within o. minutus. the results showed that the functional responses of adult o. minutus to o. loti nymphs fitted holling ii type equation, i. e., na = 1.0113n/(1 + 0.04149n) in test tubes, na = 0. 6777n/(1 + 0.03395n) in petri dishes, and na = 0.6417n/(1 + 0.03934n) in enveloped pots. the predation of o. minutus had st ... | 2006 | 17044503 |
