4-Pyridyl Carbonyl and Related Compounds as Thrips Lures: Effectiveness for Onion Thrips and New Zealand Flower Thrips in Field Experiments
摘要:
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 female 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 (female 42 times, male 25 times) but not OT, is reported as a thrips lure for the first time.

The invention provides methods for controlling thrips populations using thrips-repelling and/or thrips-attracting agents. The agents are derivatives of pyridine. The invention also provides methods of preventing or minimising damage to plants by use of the same.

spectroscopic studies. Single crystals of the nickel synergist complex have been grown from a methanol/water (10/1) solution and analyzed by single crystal X-ray diffraction. The crystal structure of the nickel synergist complex shows that Ni(II) is coordinated by four water molecules and two monodentate LI ligands and there is no direct interaction of the Ni(II) with sulfonic oxygen atoms of naphthalene-2-sulfonic

low-energy charge transfer bands is demonstrated. Thus, four series of ion pairs of 1,10-disubstituted derivatives of the [closo-B10H10]2– anion and substituted pyridinium cations were prepared and their thermal and photophysical properties were investigated. All pyridinium ion pairs form a smectic A (SmA) phase with clearing temperatures above 200 °C and intermolecular charge transfer (CT) band in the
An example of single-component multimode photoswitch was demonstrated by designing a novel Pt(II) coordination complex decorated with spiropyran, which can deliver distinct apparent colors, photoluminescent colors and liquid crystal textures in response to light.
