Abstract
Semiochemicals extracted from virgin females of the green leaf bug,Lygus lucorum Meyer-dur,were analyzed by GC-MS.The volatiles extracted comprised ten compounds identified as esters,alcohols and acids.Among the compounds identified,(E)-2-hexenyl butyrate(E)-2-henenol,butyric acid,hexyl butyrate,and(Z)-3-henenol were the major components.Three compounds,hexyl butyrate,(E)-2-hexenyl butyrate and(E)-2-henenol significantly decreased with increased female calling activity.The fact the amount of(E)-2-hexenyl butyrate decreased from 7200 ng per insect to 250 ng indicated that a large amount of(E)-2-hexenyl butyrate was emitted into the ambient air by females.Comparing the content of(E)-2-hexenyl butyrate in extracts from different parts of females,89.75% was found in the thorax together with(E)-2-henenol.We suggest that(E)-2-hexenyl butyrate is a component of the sex pheromone of female L.lucorum that is secreted by a gland,or glands,in the thorax.
