Ethylene can reduce Prays oleae attack in olive trees
An ethrel treatment of olive trees in two sites differing in altitude caused a decline in the infestation of Prays oleae, an important pest in this crop. Since the ethylene treatment did not affect natural enemies of P. oleae, we conclude that this natural compound can be used as an alternative to the use of pesticides in olive orchards. The results of this work indicate that ethrel affects P. ...
متن کاملLong-term study on the evaluation of yield and economic losses caused by Prays oleae Bern. in the olive crop of Granada (southern Spain)
A 28-year study (1970-1997) of olive trees grown in Granada (southern Spain) has revealed the levels of attack by the olive moth (Prays oleae Bern.), as well as the beneficial action of oophagous predators (Chrysopidae). On the basis of the results, the damage caused by the moth has been divided into three categories, and the yield and economic losses have been evaluated. When the final attack ...

متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Is Ground Cover Vegetation an Effective Biological Control Enhancement Strategy against Olive Pests?
Ground cover vegetation is often added or allowed to generate to promote conservation biological control, especially in perennial crops. Nevertheless, there is inconsistent evidence of its effectiveness, with studies reporting positive, nil or negative effects on pest control. This might arise from differences between studies at the local scale (e.g. orchard management and land use history), th...
