This study identifies the volatile organic compounds (VOCs) emitted by citrus when infested with California red scale (Aonidiella aurantii) and determines which of these elicit behavior responses in the predator Rhyzobius lophanthae. Headspace solid-phase micro extractions (HS-SPME) technique combined with gas chromatog.-mass spectrometry (GC-MS) was used to identify compounds and Y-tube olfactometer to determine R. lophanthae behavior responses. According to the results, 22 VOCs were detected in infested citrus plants and some of them were increased in lemon, orange and tangerine by A. aurantii infestation. R. lophanthae individuals were attracted to infested citrus saplings. According to bioassays with the olfactometer, they were attracted to Me salicylate and D-limonene at dosages of 1 and 10μL/mL by using a Y-tube olfactometer. These results explain how citrus volatiles can affect the response of the predator R. lophanthae. In the experiment, the researchers used many compounds, for example, (E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3Computed Properties of C12H20O2).
(E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Computed Properties of C12H20O2
