After the olfactory receptor is activated, the semiochemical signal must be destroyed to prevent continued stimulation. Esterase, dehydrogenase, aldehyde oxidase, epoxidase, and glutathione-S-transferase activities have all been detected in the sensillum and could degrade the signal. A further example is found in the pale-brown chafer. Phyllopertha diversa. which uses 1,3-dimethyl-2,4-( liT,3//)-quinazolinedione 10 as its sex pheromone. 

Protein extracts from antennae and legs of the Japanese beetle, the Osaka beetle, Anomala osakana, and the other scarab beetle species (Phyllopertha diversa, Holotrichia parallela, and Exomala orientalis) were incubated either... 

Some ants use ( )-2-hexenal as an alarm pheromone, while the Japanese scarab beetle, Phyllopertha diversa, has olfactory receptor neurons that are specihc for green-leaf volatiles, namely, EyZ-hexenal, (Z)-3-hexenyl acetate and (Z)-3-hexenol.
