Injecting opiate drugs is now common in the United Kingdom, particularly deprived urban areas.1 The judicious use of oral methadone may enable many dependent drug injectors to reduce or cease injecting, with consequent improvements health and social stability.2 Key elements effective treatment include ensuring ingestion an appropriate daily dose addressing patients' other problems.3 Successive reports government have emphasised key role general practitioners treating injectors.4 5 6...
Attraction of emerald ash borer, Agrilus planipennis Fairmaire, to a volatile pheromone was demonstrated in three field experiments using baited green sticky traps. A dose-response curve generated for male A. increasing release rates (3Z)-dodecen-12-olide ((3Z)-lactone) combination with the leaf volatile, (3Z)-hexenol. Only lowest rate (<2.50 μg/d) (3Z)-lactone significantly increased captures planipennis, as compared traps (3Z)-hexenol alone. Effect trap height, (3Z)-lactone, and their...
In north-central Georgia, 13 species of woodboring beetles (Coleoptera: Cerambycidae: Cerambycinae) were attracted to multiple-funnel traps baited with ethanol and one the following pheromones: (1) racemic 3-hydroxyhexan-2-one; (2) 3-hydroxyoctan-2-one; (3) syn -2,3-hexanediol. The 3-hydroxyhexan-2-one: Anelaphus pumilus (Newman), Eburia quadrigeminata (Say), Euderces pini (Olivier), Knulliana cincta (Drury), Neoclytus mucronatus (F.), scutellaris Xylotrechus colonus (F.). Clytus...
Abstract Monochamol (2-undecyloxy-1-ethanol) is a male-produced aggregation pheromone for several Monochamus Dejean (Coleoptera: Cerambycidae) species. We conducted trapping experiments in Canada, Poland, and China to test whether monochamol was attractive additional species if attraction synergised by plant volatiles bark beetle Curculionidae) pheromones. provide the first evidence of M. urussovii (Fischer) saltuarius (Gebler) or monochamol+kairomones. The highest numbers were captured...
The efficacy of various combinations pheromones and plant volatile lures for detection longhorn beetles (Coleoptera: Cerambycidae) in traps was tested field bioassays a mixed coniferous-deciduous forest near vladivostok the russian Far east 2009 2010.Traps detected 30 species (490 specimens) 23 (182 2010.Overall, 38 beetle were detected, with 15 common to both years.Species composition differed among lure treatments, but number any single did not vary significantly (12-16 per 2009; 3-10...
Male Tetropium fuscum (F.) and T. cinnamopterum Kirby mated with live dead (freeze-killed) conspecific females upon antennal contact, but did not respond to after cuticular waxes were removed by hexane rinsing. Significantly fewer males of each species attempted copulate or heterospecific than conspecifics, indicating that mate recognition was mediated species-specific contact sex pheromones in the female's hydrocarbons. GC/MS analysis elytra identified n-alkanes mono-methyl branched alkanes...
The effectiveness of a four-component "super lure" consisting ethanol (E) and the cerambycid pheromones syn-2,3-hexanediol (D6), racemic 3-hydroxyhexan-2-one (K6), 3-hydroxyoctan-2-one (K8) on trap catches Cerambycidae (Coleoptera) was determined in southeast United States with seven trapping experiments 2011-2013. We captured 74 species longhorn beetles our three-year study. Ethanol significantly increased mean number detected. Traps were effective for 8 13 previously shown to be attracted...
Abstract The invasive emerald ash borer, A grilus planipennis F airmaire ( C oleoptera: B uprestidae), is a major pest of trees, raxinus spp., in its introduced range N orth merica. Field studies were conducted to quantify the efficacy traps baited with kairomone and pheromone lures for early detection . infestation. trapping experiment demonstrated that green (3 Z )‐hexenol detected at least one adult 55.3% plots ‘nil low’‐density infestations 100% ‘moderate high’‐density infestations. Mean...

Abstract The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) is a very serious invasive pest in North America, causing extremely high levels of mortality to trees ( Fraxinus Linnaeus, Oleaceae) the United States America and Canada. Knowledge buprestid chemical ecology sparse, but appearance EAB its devastating ecological economic impacts, particularly urban environment, have provided an opportunity study semiochemistry, natural history, this detail.

The emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is a serious invasive pest of North American (Fraxinus spp.) that has caused devastating mortality since it was first identified in America 2002. In 2012, we conducted field trapping assays tested the efficacy purple prism and fluon-coated green multifunnel (Lindgren funnel) traps. Traps were baited with combinations several lures previously shown to be attractive A. planipennis: manuka oil--a sesquiterpene-rich...
Traps baited with plant volatiles and/or bark beetle pheromones have been used to survey for exotic and potentially invasive wood-boring beetles in North America since the mid-1990s.Recent discoveries of sex aggregation Cerambycidae offer means improving detection rates longhorn beetles, but little is known their effects on ambrosia subfamily Scolytinae.Our objectives were determine effi cacy host volatile trap lures Scolytinae species whether that was affected by addition pheromones.More...
Abstract Management responses to invasive forest insects are facilitated by the use of detection traps ideally baited with species-specific semiochemicals. Emerald ash borer, Agrilus planipennis Fairmaire, is currently invading North American forests, and since its in 2002, development monitoring tools has been a primary research objective. We compared six trapping schemes for A. over 2 yr at sites four U.S. states one Canadian province that represented range background densities, canopy...
