The population dynamics of the olive moth, Prays oleae (Bern) (Lep., Plutellidae) was monitored using pheromone traps containing (Z)-7-tetradecenal, from 2000 to 2002 in abandoned and commercial olive groves of Bursa in north-western Turkey. The carpophagous generation lasted significantly longer than the phyllophagous generation. The degree-days required for the anthophagous generation were significantly shorter than that for the phyllophagous and carpophagous generations. The relationship between temperature accumulations and pheromone trap captures of male P. oleae in Bursa olive groves showed a significant sigmoid relationship for the phyllophagous and anthophagous flights. Although there was generally a linear relationship between cumulative male catch and olive tree phenology, the use of the prediction model for insecticide treatments was insufficient. Cumulative male catch-degree days together with the olive tree phenology model can be used as a forecasting method for proper timing of insecticide applications against anthophagous and carpophagous larvae in olive groves.

PurposeThe aim of this research is to determine the effects of pre‐harvest harpin (H) and modified atmosphere packaging (MAP) on the storage and fruit quality of cherry tomato (Lycopersicon esculentum Mill. cvs. “Alona” and “Cluster”).Design/methodology/approachH was used at 50 g 100 l‐1 concentration. First application was done on the seedlings in 3‐4 leaf stages and the other four applications were repeated at 20‐day intervals. Then, treated and untreated fruits were stored in plastic film materials with various O2 and CO2 permeabilities.FindingsWeight loss was significantly higher in tomatoes stored under normal atmosphere (NA) compared to MAP. Initial total soluble solids of 3‐4 percent increased to 7‐9 percent in without H (WH)+NA. Firmness was measured as 0.44 (“Alona”) and 1.20 kg (“Cluster”) in H+NA and 0.17 (“Alona”) and 0.30 kg (“Cluster”) in WH+NA at the end of storage. The acidity and ascorbic acid contents of tomatoes decreased during storage. Between H and WH treatments the levels of lycopene and β‐carotene were different significantly. At the end of the study, H gave successful results in both cultivars. This success was even higher especially when the H was combined with MAP. This combination slowed down the changes in TSS, firmness values. Therefore, H+50μ PE (polyethylene) treatment was effective with regard to delaying the maturity along the storage and fruit quality in cherry tomatoes.Originality/valueHe is a plant activator. It is the first bacterial hypersensitive response (HR)‐elicitor characterized. Effectiveness of H is evaluated on quality changes in treated cherry tomato fruits.
