The volatile compounds emanating from four fermented sugar baits, palm sugar, golden cane syrup, port wine, and molasses, were isolated by headspace sampling analyzed gas chromatography−mass spectrometry. Three classes of including esters, alcohols, aromatic identified in the baits. There was a high degree qualitative similarity between contents although quantitatively they varied considerably. Ethyl acetate, 3-methylbutanol, ethyl hexanoate, 2-phenylethanol, octanoate, (E)-4-decenoate,...
The volatile compounds emitted from uninfested apple seedlings, cv. Royal Gala, and seedlings infested with generalist herbivore Epiphyas postvittana larvae were sampled using headspace collection analyzed by gas chromatography-mass spectrometry. Nine additional only detected in [including benzyl alcohol, (E)-β-ocimene, cyanide, indole, (E)-nerolidol, four unidentified compounds]. Infested produced larger amounts of (Z)-3-hexenyl acetate, linalool, 4,8-dimethyl-1,3(E),7-nonatriene, methyl...
The flowers of Canada thistle, Cirsium arvense (L.), attract a wide range insects, including pollinators and herbivorous species. This attraction is primarily mediated by floral odor, which offers potential for developing generic insect attractants based on odor. In this study, we have analyzed the chemical composition volatiles produced thistle flowers. Nineteen compounds were identified in headspace, phenylacetaldehyde (55%), methyl salicylate (14%), dimethyl (8%), pyranoid linalool oxide...
Abstract BACKGROUND: The behavioural response of both sexes codling moth, Cydia pomonella to the pear‐derived kairomone (ethyl (2E,4Z)‐2,4‐decadienoate), moth sex pheromone ( E , ‐8,10‐dodecadien‐1‐ol), and combined with pear derived loaded into red rubber septum were investigated in trapping experiments New Zealand apple orchards. A range 0.01–10.0 mg loading dispensers was tested highest catch males traps baited 1.0 mg. No dose trap seen different amounts (0.01–10.0 mg). RESULTS: number...

Abstract Cerambycid species of the Spondylidinae subfamily are distributed worldwide and known for being prolific invaders that infest conifers. In New Zealand, Arhopalus ferus (Mulsant), burnt pine longhorn beetle, is well-established requires monitoring at high-risk sites such as ports, airports, sawmills part requirements to meet log export standards set by Zealand Ministry Primary Industries (MPI). Currently, its surveillance relies on traps baited with host volatiles (i.e., ethanol...
Abstract BACKGROUND: The common wasp, Vespula vulgaris (L.), and the German germanica (F.), are significant problems in New Zealand beech forests ( Nothofagus spp.), adversely affecting native birds invertebrate biodiversity. This work was undertaken to develop synthetic attractants for these species enable more efficient monitoring management. RESULTS: Seven known wasp (acetic acid, butyl butyrate, isobutanol, heptyl octyl butyrate 2,4‐hexadienyl butyrate) were field tested, only attracted...
Abstract The sterile insect technique ( SIT ) potentially provides a socially acceptable approach for eradication of new pest incursions. light brown apple moth, E piphyas postvittana W alker) L epidoptera: T ortricidae), was discovered in Berkeley (CA, USA) 2006, leading to an incursion response that included this technology. In study, we assessed factors affecting mating success from bisex release irradiated moths: effects radiation dose on male multiple mating, flight competition, female...
Abstract Vespid wasps ( V espula vulgaris L . and germanica F ab. H ymenoptera; espidae) are highly abundant in 1 million ha of N ew Z ealand's indigenous beech forests othofagus spp.) have had detrimental effects on the ealand native fauna. This hyperabundance is due part to vast supply carbohydrate‐rich honeydew produced by scale insects U ltracoelostoma spp. ealand. Current control methods include use wet cat food as a protein source with insecticide lure‐and‐kill‐based system, but there...
The soybean looper, Thysanoplusia orichalcea (F.), is a polyphagous insect pest of vegetable crops. Indonesian in origin, it has spread to Europe, India, Africa, Australia and New Zealand. identification an attractant for female T. could enable the development alternative management strategies those provided by insecticides or sex pheromones, which are often only attractive males.Traps baited with synthetic lures derived from Canada thistle, Cirsium arvense (L.) Scop., floral volatiles...
The midge Dasineura mali (Kieffer) (Diptera: Cecidomyiidae) is a significant pest of apples (Malus spp.), and the recent identification female sex pheromone enabling new direct control tactics to be considered. Direct using male suppression will require knowledge frequency multiple mating, dispersal colonization rates, efficiency removal. Males were able mate up five times, with mean 2.7 times when presented in 10 female-to-1 group, designed simulate suppression. Male catch response loading...
Pheromones of two native leafrollers economic importance to the New Zealand horticulture industry, Planotortrix octo [(Z)-8-tetradecenyl acetate and tetradecyl acetate] Ctenopseustis obliquana [(Z)-5-tetradecenyl (Z)-8-tetradecenyl acetate], were reinvestigated combined with pheromone Epiphyas postvittana [light-brown apple moth, (E)-11-tetradecenyl actetate (E, E)-9,11-tetradecen-1-yl develop a single dispenser for mating disruption three pest species integrated management.Additional...
Abstract Parasitoid biological control agents rely heavily on olfaction to locate their hosts. Chemical cues associated with hosts and non-hosts are known influence the expression of host preferences host-specificity. A better understanding how why parasitoids attack some species not others, based volatile organic compounds potential hosts, can provide key information parasitoid’s preferences, which could be applied pre-release risk assessments for classical agents. Electrophysiological...
Abstract Mealybugs are phloem-feeding insects found on many crops worldwide. In New Zealand vineyards, they transmit the economically important Grapevine leafroll-associated virus 3 (GLRaV-3). For some mealybug species, synthetic sex pheromones have been commercialised, and used as monitoring tools. The mealybugs Pseudococcus longispinus calceolariae major pests in vineyards. We present work development of a combined P. pheromone lure. optimal dose for was to be 10 µg ( S )-(+)-enantiomer,...
Phenol the attractant pheromone of adult males native New Zealand grass grub Costelytra zealandica (White) is produced in beetles as result bacterial degradation tyrosine A lure consisting a resin impregnated with phenol has been widely used to monitor male beetle flight activity The present formulation highly attractive for first week field but then loses rapidly number phenolcontaining formulations were tested improve new gave lower catches that more stable time producing data suitable...
Abstract The Queensland fruit fly (Bactrocera tryoni) is a major polyphagous pest widespread in Australia and several Pacific Islands. Bacteria present on the host plant phyllosphere supply proteins, essential for egg development female sexual maturity. We investigated role of microbial volatile organic compounds (MVOCs) attracting virgin females. Four Enterobacteriaceae commonly found gut B. tryoni were cultured different media (artificial natural fruits), their MVOCs collected using two...
