The objective of this study was to identify the aggregation pheromone of the melon thrips Thrips palmi, a major pest of vegetable and ornamental plants around the world. The species causes damage both through feeding activities and as a vector of tospoviruses, and is a threat to world trade and European horticulture. Improved methods of detecting and controlling this species are needed and the ...

Sirex noctilio F. (Hymenoptera: Siricidae) is an invasive woodwasp, currently established in northeastern North America. In other regions of the world, stressed trap trees are used to monitor populations of S. noctilio and to provide inoculation points for the biological control nematode Deladenus siricidicola Bedding. However, the operational use of trap trees for S. noctilio in North America ...

Sex Pheromone Components, Autographa gamma, Z -7-Dodecenyl Acetate, Z-7-Dodecenyl Alcohol Z-7-Dodecenyl acetate and Z-7-dodecenyl alcohol have been identified as sex pheromone components o f female Autographa gamma. This is the first time that Z-7-dodecenyl alcohol has been found in the natural pheromone o f Plusiinae. When incorporated in pheromone traps of some Plusiinae species the alcohol i...

McPhail traps loaded with various attractant solutions (ammonium sulphate, Entomela 75%, Entomela 50%, Dacus bait 100, sexual pheromone of olive fruit fly Bactrocera oleae) combined also with registered plant protection products (lambda-cyhalothrin, alpha-cypermethrin as well as dimethoate) were tested for their attractiveness which was indicated as captures of flies in McPhail traps during thr...

W. Barros-Parada, A.L. Knight, E. Basoalto, and E. Fuentes-Contreras. 2013. An evaluation of orange and clear traps with pear ester to monitor codling moth (Lepidoptera: Tortricidae) in apple orchards. Cien. Inv. Agr. 40(2):307-315. Studies were conducted to evaluate the use of several trap-lure combinations to improve the monitoring of codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricid...

The efficacy of methyl bromide fumigations in mills (6 mills) was compared to heat treatments (3 mills), sulfuryl fluoride (ProFume®) (4 mills) and phosphine (ECO2FUME®), heat and carbon dioxide combination treatment (2 mills). The efficacy of treatments was estimated in three ways: Tribolium castaneum adults and eggs in vials during treatment, pheromone traps and rebolt sifter tailings counts....

Eradication programs for the boll weevil (Anthonomus grandis grandis Boheman) rely on pheromone-baited traps to trigger insecticide treatments and monitor program progress. A key objective of monitoring in these programs is the timely detection of incipient weevil populations to limit or prevent re-infestation. Therefore, improvements in the effectiveness of trapping would enhance efforts to ac...

1 To improve the monitoring of the invasive European woodwasp, both sexes of Sirex noctiliowere studied in a walk-in wind tunnel. We evaluated three trap types: unbaited traps, traps baited with a three-component pheromone lure and traps baited with a commercial Sirex kairomone lure and ultraviolet light. 2 When no lure was present, the black intercept trap caught more females than the clear ja...

Parent (re-emerged) spruce bark beetles (Ips rypographus L., Col.; Scolytidae) beginning a second host-seeking flight were collected in pheromone-baited traps. These beetles were marked with fluorescent powder of different colors and released from a point source (9-16 June 1989) within a spruce, Picea abies L., forest (Jurbarkas forest district, Lithuania). Some of the marked beetles were recap...

Previous work documented seasonal field response dynamics of Euschistus conspersus Uhler (Heteroptera: Pentatomidae) to Euschistus spp. pheromone [methyl (2 E ,4 Z )-decadienoate]-baited traps in California processing tomatoes, Lycopersicon esculentum (Miller) (Solanaceae). A laboratory phenology model has been reported for E. conspersus egg incubation to adult emergence. In the present work, r...
