Studies were conducted to assess glacial acetic acid (GAA) with various host plant volatiles (HPVs) and the sex pheromone, (E,E)-8, 10-dodecadien-1-ol, of codling moth, Cydia pomonella (L), as lures in traps for tortricid pests that often co-occur in tree fruits in the western United States. In addition to codling moth, field trapping studies were conducted with oriental fruit moth, Grapholita ...

Pheromone traps were used to assess the distribution of two pheromone races of European corn borer, Ostrinia nubilalis (Hübner), in North Carolina, 10 and 20 yr after previous, similar assessments. In the previous studies, moths responding to a 97Z: 3E isomeric blend (Z blend) of 11-tetradecenyl acetate predominated in the far western parts of the state, whereas moths responding toa3Z: 97Eblend...

The midge Contarinia nasturtii Kieffer (Diptera: Cecidomyiidae) was Þrst conÞrmed inNorthAmerica inOntario, Canada, in 2000. The insect is nowdistributed throughoutmany counties in theprovincesofOntario andQuébec.Nearly 1,200 farms in thenortheasternUnitedStates that grow cruciferous vegetables are at risk forC. nasturtii infestation if this insect were to spread to that region. Over a period o...

Field studies were conducted in the United States, Hungary, and New Zealand to evaluate the effectiveness of septa lures loaded with ethyl (E,Z)-2,4-decadienoate (pear ester) and (E)-4,8-dimethyl-1,3,7-nonatriene (nonatriene) alone and in combination with an acetic acid co-lure for both sexes of codling moth, Cydia pomonella (L.). Additional studies were conducted to evaluate these host plant v...

O Objective: To perform the first molecular characterization of barcoding COI region S. frugiperda found in Tabasco and to test whether it can reliably identify strain detected said state. Design/Methodology/Approach: We collected specimens using four pheromone traps placed corn plots. Subsequently, we implemented DNA extraction, PCR with LCO-L/HCO-L primers, sequencing six individuals captured...

We report the identification and field bioassays of a major component of the male-produced aggregation pheromone of Anelaphus inflaticollis Chemsak, an uncommon desert cerambycine beetle. Male A. inflaticollis produced a sex-specific blend of components that included (R)-3-hydroxyhexan-2-one, (S)-2-hydroxyhexan-3-one, 2,3-hexanedione, and (2R,3R)- and (2R,3S)-2,3-hexanediols. Field trials with ...

Several integrated pest management programs rely on the use of mating disruption tactics to control insect pests. Some programs specifically target non-native species, such as the gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae). We evaluated SPLAT GM, a new sprayable formulation of the gypsy moth sex pheromone disparlure, for its ability to disrupt gypsy moth mating. The study was...

The alpha2u-globulin (alpha2u) is a pheromone carrier urinary protein believed to be relevant for sexual communication among rats and is characterized in laboratory rats. In the present study 17 kDa protein and the bound pheromones were characterized in a population of wild-type Indian common house rat (Rattus rattus). The protein was purified by two runs of Sephadex G-50 chromatography and ana...

We conducted four behavioral choice tests in stands of mature lodgepole pine in British Columbia, from 1988 to 1991, to determine the dose-dependent responses of Orthotortzicw 1atid;ns (1,eConte) and Ips pini (Say) to their respective pheromones. Dose-dependent responses were exhibited by I. pini to (5)-ipsdienol and lanierone, with trap catches directly proportional to pheromone release rates....

All aphid species studied so far share the same sex pheromone components, nepetalactol and nepetalactone. Variation by different enantiomers and blends of the two components released by different aphid species are limited and can only partially explain species-specific attraction of males to females. While some host-plant odours are known to enhance specific attraction of aphid species, herbivo...
