On the basis of structural and/or aroma analogies to known thrips (Thysanoptera: Thripidae) lures, 35 compounds (18 pyridine derivatives, 13 benzene derivatives, and 4 other compounds), consisting of both synthetic and naturally occurring compounds, were screened for their ability to bring about increased thrips capture in field experiments using water traps in Canterbury, New Zealand. Most of the thrips caught were New Zealand flower thrips (NZFT) (Thrips obscuratus) or onion thrips (OT) (Thrips tabaci). The greatest increase in capture for NZFT (158 times for ♀ cf. to water control) was for the known lure ethyl nicotinate, a 3-pyridyl ester. Ethyl isonicotinate, the 4-pyridyl regioisomer of ethyl nicotinate, not previously reported as a thrips lure, provided the greatest increases in capture for OT (31 times) of any of the compounds tested, significantly more than ethyl nicotinate. Other 4-pyridyl carbonyl compounds, including ethyl 4-pyridyl ketone, also increased OT capture significantly. The natural floral compound cis-jasmone, which increased trap capture of NZFT (♀ 42 times, ♂ 25 times) but not OT, is reported as a thrips lure for the first time.
ESR INVESTIGATION OF A NEW LYOTROPIC LAMELLAR PHASE FROM AN AMPHIPHILE WITH A CATIONIC HEAD GROUP.

A new lamellar lyotropic phase with a positively charged polar interface has been obtained by mixing water and decanol with n-decyl isonicotinate hydrochloride in appropriate concentration. The order parameters of several spin probes incorporated in this mesophase have been determined by electron spin resonance spectroscopy. A comparison is made with the results for the same probes in the lamellar phase of water, decanol, and sodium decanoate, having an anionic interface. The experimental findings are rationalized in terms of selective interactions of the probes with specific regions of the bilayers.
