[0582] .sup.1H-NMR, respectively .sup.13C-NMR: The signals are characterized by chemical shift δ (ppm) vs. tetramethylsilane, respectively CDCl.sub.3 for .sup.13C-NMR, by their multiplicity and by their integral (relative number of hydrogen atoms given). The following abbreviations are used to characterize the multiplicity of the signals: m=multiplett, q=quartett, t=triplett, d=doublet and s=singulett. The coupling constant (J) is expressed in Hertz (Hz).

Orchid Thrips (Dichromothrips Corbetti)

[0595] Dichromothrips corbetti adults used for bioassay were obtained from a colony maintained continuously under laboratory conditions. For testing purposes, the test compound is diluted in a 1:1 mixture of acetone:water (vol:vol), plus 0.01% vol/vol Alkannuls® EL 620 surfactant.

[0596] Thrips potency of each compound was evaluated by using a floral-immersion technique. Plastic petri dishes were used as test arenas. All petals of individual, intact orchid flowers were dipped into treatment solution and allowed to dry. Treated flowers were placed into individual petri dishes along with about 20 adult thrips. The petri dishes were then covered with lids. All test arenas were held under continuous light and a temperature of about 28° C. for duration of the assay. After 3 days, the numbers of live thrips were counted on each flower, and along inner walls of each petri dish. The percent mortality was recorded 72 hours after treatment.

Rice Green Leafhopper (Nephotettix virescens)

[0598] Rice seedlings were cleaned and washed 24 hours before spraying. The active compounds were formulated in 50:50 acetone:water (vol:vol), and 0.1% vol/vol surfactant (EL 620) was added. Potted rice seedlings were sprayed with 5 ml test solution, air dried, placed in cages and inoculated with 10 adults. Treated rice plants were kept at about 28-29° C. and relative humidity of about 50-60%. Percent mortality was recorded after 72 hours.
