Claims
- 1. A method for killing an insect which comprises exposing the insect to an effective amount of ##STR6## wherein x is an integer between 0 and 8 and R is selected from the group consisting of a direct bond, --CH.dbd.CH-- and --CH.dbd. furanyl.
- 2. The method of claim 1 wherein the pyrone is ##STR7##
- 3. The method of claim 1 wherein the pyrone is a ##STR8##
- 4. The method of claim 1 wherein the pyrone is a ##STR9##
- 5. The method of claim 1 wherein the pyrone is ##STR10##
- 6. The method of claim 1 wherein the nitrophenyl pyrone is selected from the group consisting of ##STR11##
- 7. The method of claim 1 wherein the insect is exposed to an amount between about 0.001 and 100 ppm by weight of the compound.
- 8. A method for killing an insect which comprises exposing the insect to an effective amount of a compound selected from the group consisting of spectinabilin, aureothin, luteoreticulin, griseulin and isomers thereof to kill the insect.
- 9. The method of claim 8 wherein the compound is spectinabilin.
- 10. The method of claim 8 wherein the insect is in a soil.
- 11. The method of claim 8 wherein the insect is mosquito larvae.
- 12. The method of claim 11 wherein the mosquito larvae is Aedes egyptii.
