The use of compounds of formula I (in 2,3-threoconfiguration) <IMAGE> I wherein n is an integer from 5 to 9, R' and R'' are equal or different, and are each selected from the group consisting of hydrogen, lower alkyl, or are together O (oxygen) or =CH2 (methylene), and R is lower alkyl, for the inhibition of pheromone mediated attraction between male and female of pest insects, particularly of the family Diprionidae; the use of compounds of the formula II (in 2,3-erythroconfiguration): <IMAGE> II wherein n is an integer from 5 to 9, Ra' is hydrogen, and Ra'' is lower alkyl, or Ra' and Ra'' together form methylene, and Ra is lower alkyl, as an attractant for pest insects, preferably of the family Diprionidae.
