NEW SEX ATTRACTANTS AND INHIBITORS FOR 17 MOTH SPECIES FROM THE FAMILIES GRACILLARIIDAE, TORTRICIDAE, YPONOMEUTIDAE, OECOPHORIDAE, PYRALIDAE AND GELECHIIDAE

Field screening tests of 21 saturated and monounsaturated straight cha in C-12 and C-14 alcohols and their acetates as well as some binary mi xtures in dosages of 1 and 0.2 mg/dispenser were carried out in Lithua nian in 1993 and 1994. New sex attractants were determined for males o f five moth species of the family Gracillariidae (E10-12:OH for Phyllo norycter soi bi, E10-12Ac for Ph. cydoniella and Ph. oxyacanthae, Z10- 12:OAc for Ph. junoniella, and a mixture of Z10-14:OAc with E9-14:OAc in a 1:10 for Pit. sylvella), for four species of the family Tortricid ae (E10-14:OAc for Endothenia ericetana, Z10-14:OAc in a 10:1 mixture with E11-14:OAc for Eudemis pozphyrana, E11-14:OAc in a 10:1 mixture w ith E11-14:OH for Dichrorampha petiverella and Cochylis dubitana), for two species of Gelechiidae (Z9-14:OAc in a mixture with either Z10-14 :OAc in a ratio 1:1, E9-14:OAc in a ratio 1:10 or E10-14:OAc in a rati o 10:1 for Bryotropha galbanella, Z10-14:OAc and E9-14:OAc in a ratio 10:1 for B. mundella), as well as for one species of each of the famil ies Yponomeutidae (Z7-14:OAc for Paraswammerdamia lutarea) and Oecopho ridae (Z10-14:OAc and E9-14:OAc in a ratio 10:1 for Pseudatemelia jose phinae). Preliminary composition of sex attractants was established fo r three moth species of the family Gracillariidae (Z10-14:OAc in a 1.1 0 mixture with E9-14:OAc for Phyllonorycter heegerella, Ph. coryli and Ph. dubitella) and for one species of the family Gelechiidae (Z9-14:O Ac for Bryotropha terella). Inhibitors of the sex attractants were fou nd for four leafminer species of the family Gracillariidae (Z7-, Z9- a nd Z10-12:OAc for Phyllonorycter sorbi, Z10-, E10-12:OH and E10-14:OH for Ph. mespilella, E10-12:OH for Ph. cydoniella, Z10-12:OH and E10-14 :OH for Ph. oxyacanthae), for three species of Tortricidae (E9-, Z11- and E11-14:OAc for Endothenia ericetana, E11-14:OAc for Gypsonoma minu tana, E10- and E11-14:OAc for Epagoge grotiana), and for one species f rom the family Pyralidae (Z10-, E10- and E11-14:OAc for Pyrausta aurat a). Data from male behaviour tests in tube olfactometers are presented for Phyllonorycter blancardella, Ph. sorbi, Ph. dubitella and Ph. str igulatella and active compounds revealed.
