    Notes: Abstract The major component (〉90% of volatiles) of the male rectal glandular extract of the nonpest speciesBactrocera visenda (Hardy) is 3-methyl2-butenyl acetate, with minor components being the isomeric 3-methyl-3-butenyl acetate, the homologous esters, 3-methyl-2-butenyl propanoate and 3-methyl-2-butenyl formate, along with 3-methyl-2-buten-1-ol, 3-methyl-2-butenal, and 3-methylbutyl acetate. None of these compounds has been identified previously from aBactrocera species, supporting the view thatBactrocera visenda is taxonomically distant from otherBactrocera species identified from the Australian mainland. This collection of compounds adds to the known types utilized by dipteran species and emphasizes their extensive biosynthetic capability.

    Identification, synthesis, and bioactivity of a male-produced aggregation pheromone in assassin bug,Pristhesancus Plagipennis (Hemiptera: Reduviidae) (1994)

    Notes: Abstract Pristhesancus plagipennis, a large Australian assassin bug, possesses three pairs of dorsal abdominal glands (DAGs). In the male, the anterior and posterior glands are hypertrophied and secrete an attractant pheromone. Gas chromatography-mass spectrometry (GC-MS) analyses of male DAG extracts and airborne volatiles emitted from calling males showed the pheromone signature to be dominated by a novel component. Subsequent chemical manipulations, GC-MS, and chiral-column analyses established its identity as (Z)-3-hexenyl (R)-2-hydroxy-3-methylbutyrate. Minor components included 3-methylbutanol, 2-phenylethanol, (Z)-3-hexenol, decanal, (E)-2-hexenoic acid, and three minor hexenyl esters. Bioactivity studies using laboratory olfactometers and outdoor flight cages demonstrated attraction by femaleP. plagipennis to calling males, heptane extracts of male posterior DAGs and a synthetic formulation of the (Z)R enantiomer of the major ester, alone or in combination with other components of male anterior and posterior DAGs. Males were also attracted to the major ester. The racemate andS enantiomer of the ester were not attractive. Contamination of the (Z)R enantiomer with 30–60% of theE isomer also made the compound nonattractive. This is the first report of an aggregation pheromone in the Reduviidae. The prospects for pheromonal manipulation ofP. plagipennis populations to enhance the value of this predator in horticultural ecosystems, are discussed.

    Chemistry of fruit flies: Nature of glandular secretion and volatile emission ofBactrocera (bactrocera) cacuminatus (Héring) (1991)
    Springer
    Journal of chemical ecology 17 (1991), S. 485-495 
    Details
    ISSN: 1573-1561
    Keywords: Bactrocera cacuminatus ; Bactrocera oleae ; Diptera ; Tephritidae ; olive fly ; spiroacetal ; ketoalcohol ; chirality

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The major component of the rectal glandular extract and volatile emission of maleBactrocera cacuminatus is racemic 1,7-dioxaspiro[5.5]undecane. l-Hydroxy-5-nonanone as its open chain form, together with 6-n-butyl-3,4-dihydro-2H-pyran are minor components. 1,7-Dioxaspiro[5.5]undecan-4-ol is present at a low level and is shown to be exclusively the diastereomer with an equatorial hydroxy group by comparison with synthesized samples of both epimers. Examination of the trifiuoroacetate by chiral gas chromatography has established the (4S,6S) stereochemistry (ca. 80% ee). The presence of 1,7-dioxaspiro[5.5]undecan-3-ol, or its isomerization product, 1,6-dioxaspiro[4.5]decan-2-ylmethanol, could not be confirmed. Trapping of the volatiles released by sexually mature male flies at dusk revealed that a number of the glandular components described above are released at mating time. Reexamination of the glandular secretion of sexually mature female olive flies (B. oleae) has failed to confirm the presence of any 1,7-dioxaspiro[5.5]undecanols, with the only volatile component (other than fatty acids) being 1,7-dioxaspiro[5.5]undecane.

    Mass-trapping ofCarpophilus spp. (Coleoptera: Nitidulidae) in stone fruit orchards using synthetic aggregation pheromones and a coattractant: Development of a strategy for population suppression (1996)

    Notes: Abstract Experiments were conducted in southern New South Wales to evaluate the potential of mass-trapping using synthetic aggregation pheromones and a coattractant as a control option forCarpophilus spp. in stone fruit orchards. A cordon of 54 pipe and 54 funnel traps (one trap of each type per perimeter tree) baited with pheromones ofC. mutilatus andC. davidsoni and coattractant (fermenting bread dough) was maintained around an apricot orchard for three weeks prior to harvest. The incidence ofCarpophilus spp. in ripe fruit in the center of the orchard was significantly reduced compared to a nearby orchard or the perimeter trees containing traps. A cordon of 16 water-filled Magnet funnel traps baited with pheromones ofC. mutilatus andC. davidsoni and coattractant was placed around a 9 × 9 block of trees in a peach orchard (single traps on alternate perimeter trees). This trapping regime significantly reduced infestation of fruit baits byCarpophilus spp. in the center tree over a period of six weeks compared to fruit baits in trap trees and distant (100 m) control trees. However, cordons of eight pheromone traps within 1 m of single trees or a single trap adjacent to a tree increasedCarpophilus spp. infestation of fruit baits by up to 7.5 × compared to trees without pheromone traps. Mass-trapping based on perimeter positioning of pheromone traps (at a yet to be determined distance from protected trees) appears to show potential as a control strategy forCarpophilus spp. in stone fruit orchards during fruit ripening and harvest but traps too close to trees must be avoided. Development of a strategy for population suppression is discussed with respect to trap type, efficacy, positioning, and density; pheromone and coattractant delivery systems; and orchard sanitation.
