beetles. |

is a available for the following crawling stored-product insects.
Pheromone lures are on sale.
Red flour
beetle (Tribolium castaneum)
Confused flour beetle (Tribolium confusum)
Lesser grain borer (Rhyzopertha dominica)
Saw-toothed
grain beetle (Oryzaephilus surinamensis)
Pheromone lures are under development.
Maize
weevil (Sitophilus zaemais) |
These lures contain an aggregation pheromone that attracts adults
male and female. The only saw-toothed grain beetle's lure is used
aggregation pheromone and food attractant.
""

the walls in the working area, warehouse or storage area. Place
traps 5 to 10 m apart, but away from manufacturing lines so as to
avoid attracting adults that may contaminate products. |
| Shelf
life and useful life |
| Stickers and pheromone lures can be
stored for one year after being manufactured. The useful life is
one month after the trap is set up. Keep the trap kits in a dark
place at a temperature of 10 to 40 °C. Storing the lures in
a refrigerator or a freezer will cause them to deteriorate. |
