Description
Summary:Volatiles collected on Poropak Q from fusiform rust galls (Cronartium quercuum F. sp. fusiforme ) of loblolly pine for 3 hr were better oviposition stimulants for Dioryctria amatella (Hulst) females than extracts of 8-hr collections. Comparison of volatiles from second-year loblolly pine cones with those from fusiform galls showed that both contained dl- alpha -pinene, (-)- beta -pinene, myrcene, and (+)-limonene. Camphene was found in galls only, and relatively large quantities of beta -phellandrene were identified only from cones. The five major monoterpenes found in the two host substrates were tested in an oviposition bioassay. The combination of alpha -pinene, myrcene, and limonene was as attractive to D. amatella females as all other terpene combination, including turpentine.
