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 کاملEffects of olive scale (Parlatoria oleae (Colvée)) attack on yield, quality and fatty acid profile of virgin olive oil

متن کاملReduction of olive fly, Bactrocera oleae (Rossi, 1790), damage by selecting native and exotic olive cultivars
Olive fly is the most dangerous pest in olive groves worldwide. Therefore the study of the most susceptible and resistant cultivars to olive fly can bring new information to diminish the olive flies harmful impacts. The main goal of the present study is to verify the olfactory response of olive fly to olive volatiles from five native Iranian cultivars (Fishomi, Mari, Rowghani, Shengeh, and Zard...
متن کاملComputer Design of Novel Pesticides Against the Olive Fruit Fly (Bactrocera oleae)
The olive fruit fly Bactrocera oleae targets the fruits of olive trees in the Mediterranean and has been causing increasing economic harm to Californian growers. Past efforts to combat Bactrocera oleae by limiting the spread of its population have included traps, bait sprays, barrier films, and the release of natural predators, but these methods do little against large populations and many frui...
متن کاملWater Status of Olive Trees
Leaf water potential (') and leaf conductance (gl) were measured in the field in 20-year-old olive trees subjected to two treatments of soil water content (dry-farming and drip-irrigation). Differences between treatments of up to 0.35 MPa were observed in predawn , values. At midday, these differences were of up to 0.83 MPa. However, no significant differences between treatments were observed i...
