Lymantria monacha Disparlure

Boness 568) used disparlure in field trials against the nun moth, Lymantria monacha, which is closely related to the gypsy moth. After treating 5 hectares of pine forest with 5.4 g of microencapsulated disparlure, he distributed 40 small disparlure-baited traps in the central part of the plot. Catches were reduced by 99% in comparison with a control plot. 

Some lepidopteran species secret methyl-branched chemicals for their sexual communication. These have been abbreviated with Me to indicate the position of the methyl group. Disparlure (Me2,epo7-18 H) is a well-known pheromone identified from Lymantria dispar [3] and two other species in the same genus, L.fumida [95] and L. monacha [96]. L. monacha also secrets an... 

L. monacha is sympatric with five other congeners, including Lymantria fumida, which has (7 .85)-cA-7,8-epoxy-2-methyloctadecane (called (+)-disparlure ) as...
