    Assessment of the potential of sex pheromones as strategic lures for the control of canegrubs : SRDC final report BS17S
    (BSES, 1991) Allsopp, PG; Stickley, BDA
    Sex pheromones were shown to be emitted by females of Antitrogus consanguineus, A. parvulus and L. picticollis. Attraction of males of L. picticollis to females of A. consanguineus shows that the compound or compounds involved are similar in those two species. Detection of pheromones was probably related to the morphology of the adult antennae. One compound was present in emissions of adult female L. negatoria, but this compound could not be identified.

    Assessment of aromatic compounds as strategic lures in a canegrub control program : SRDC final report BS34S
    (BSES, 1991) Allsopp, PG
    Anethole, n-butyric acid, citral, citronellal, eucalyptus oil, eugenol, geraniol, hexanoic acid, hexan-1-ol, 3-hexen-1-ol, 1-nonanol, pentanoic acid, phenol, sorbic acid and the standard Trece Japanese beetle floral lure (10:22:11, 2-phenylethylpropionate: eugenol: geraniol) were tested as attractants for Anoplognathus porosus, Antitrogus consanguineus, A. parvulus, Dermolepida albohirtum, Lepidiota crinita, L. negatoria, L. noxia, L. picticollis, and Metanastes vulgivagus. None were effective attractants. The apparent activity of sorbic acid would justify testing butyl sorbate as an attractant.

    Field Experiments to Optimise Lures for Mass-Trapping of Cane Weevil Borer
    (BSES, 1998) Robertson, LN; Giblin-Davis, RM; Oehlschlager, AC
    Cane weevil borer, Rhobdoscelus obscurus (Biosduval) (Coleoptera: Curculionidae: Rhynchophorinae), is an introduced pest of sugarcane in Queensland, Hawaii and Fiji. It was accidentally introduced from Papua New Guinea about 1900 with sugarcane planting material (Veitch 1917). Previous research showed that male cane weevil borers produce aggregation pheromones which attract both male and female cane weevil borers. Three compounds emitted by feeding males were identified by Dr R Gries ata Simon Fraser University (see Robertson et al 1997). These compounds were synthetically produced by ChemTica Internacional SA and two of these, 2-methyl-4-octanol and 6-methyl-2-hepten-4-ol (rhynchophorol), were shown to be the active compounds for attracting cane weevil borer (Robertson et al 1997). The experiments reported here were designed to determine the optimum ratio of the two active compounds to attract cane weevil borer. In addition, the relative attractiveness of they synthetic lures was compared with that produced by feeding male cane weevil borers. Finally, a chemical known to increase trap catches of other species of Rhynchophorinae, ethyl acetate (marketed as 'Weevil Magnet'), was tested for its ability to synergise the attractiveness of the aggregation pheromones.
