Three strawberry (Fragaria x ananassa. Duch.) varieties commercially grown in Israel (Tamar, Yael and Malach) were studied for their volatile compositions. Two techniques were compared: headspace solid phase micro extraction (HS-SPME) and liquid-liquid extraction (organic solvent: tert-butyl methyl ether) by gas chromatography/mass spectrometry (GC/MS). The influences of techniques on the volatile compounds were tested by comparing the volatiles determined in the 3 varieties. Malach, the most aromatic variety, accumulates high levels of furanones and esters compared to the other varieties. Differences in the aroma profiles obtained by utiliszing different techniques were noted. HS-SPME was more suitable for the determination of …

The potential of the predatory mite Phytoseiulus persimilis (Acarina: Phytoseiidae) to control the carmine spider mite Tetranychus cinnabarinus (Acarina: Tetranychidae) on strawberries (cv. ´Camarosa`) grown under plastic tunnels was investigated in 2 fields during the 2001 and 2002 growing seasons in Aydın, Turkey. Three study plots, grower's practice, chemical control and biological control, were established. The population of T. cinnabarinus was controlled in the grower's practice plots by using 1 or 2 acaricide applications. However, it was suppressed with only 1 acaricide application in the chemical control plots at a population level below economic threshold levels. When the pest population …
