Diapause status of females affects attraction of male pear psylla, Cacopsylla pyricola, to volatiles from female-infested pear shoots
A companion study showed that male pear psylla, Cacopsylla pyricola (Förster) (Homoptera: Psyllidae) were attracted to volatiles from pear shoots infested with post-diapause females. The present study compared the behavioral response of males to diapause and post-diapause females. Assays were done using a Y-tube olfactometer. We collected male and female winterform psylla from pear orchards at ...

15 صفحه اولEffect of Salicylic Acid on Pear Leaf Induced Resistance to Pear Ring Rot
To reveal the mechanism of resistance of pear against ring rot induced by SA, the influence of SA treatment on disease severity and plant defense enzymes were studied with Pyrus bretschneideri cv. Yali and Physalospora piricola Nose as the materials. It is interesting to note that the resistance of pear to P. piricola could be greatly increased by the treatment of 0.2 mM SA. In the present stud...
متن کاملHeadspace Volatiles of Selected Melon, Pear and Carrot Cultivars
Herein, we report on the results of solventand sorbent-free HS-GC-MS (headspace – gas chromatography – mass spectrometry) analysis of the headspace volatiles (HSVs) of fruits of cultivated melon (Cucumis melo L. cultivar “ananas dinja” [pineapple melon]) and pear (Pyrus communis L. cultivar “Julska lepotica” [the beauty of July]), as well as of underground parts of carrot (Daucus carota L. cult...
متن کاملFeeding-induced rearrangement of green leaf volatiles reduces moth oviposition
The ability to decrypt volatile plant signals is essential if herbivorous insects are to optimize their choice of host plants for their offspring. Green leaf volatiles (GLVs) constitute a widespread group of defensive plant volatiles that convey a herbivory-specific message via their isomeric composition: feeding of the tobacco hornworm Manduca sexta converts (Z)-3- to (E)-2-GLVs thereby attrac...
