Oviposition Preferences for Infusion-Baited Traps and Seasonal Abundance of Culex Mosquitoes in Southwestern Virginia
… Theobald and Culex pipiens Linnaeus using ovitraps and gravid traps. Both species have been implicated as enzootic and epizootic vectors of West Nile virus (WNV) and these studies provide information on the relative abundance of gravid mosquitoes. Ovitraps were used in the summers of 2002 and …

Biological Control of Red Imported Fire Ant (Solenopsis invicta) Using Pseudacteon (Diptera: Phoridae) in Central Arkansas
… fly sampling methods, hand aspirating and sticky traps, were studied. A vacuum aspirator was compared with two sticky trap configurations. Sticky traps used one of three bait types: live fire ants, dead fire ants, and foraging fire ants. Both P. curvatus and P. tricuspis were captured, but many …

Vertical activity, host preference, and population studies of adult Culicoides (Diptera: Ceratopogonidae)
Automatic-collecting, animal-baited traps were used to investigate the vertical activities and host preferences of Culicoides species in a forest in Giles County, Virginia. Using ropes and pulleys, rabbit and turkey-baited traps were positioned at ground level, 25, and 50 feet elevation in a forest …

The Role of Attractants and Feeding Stimulants in The Selection of Cucurbita Flowers by Diabroticite Beetles, (Coleoptera: Chrysomelidae)
… bioassay. Field testing of indole using sticky traps showed it to be a potent attractant of the western corn rootworm, Diabrotica virgifera virgifera Le Conte and the striped cucumber beetle, Acalymma vittatum (Fabr.). The southern corn rootworm, Diabrotica undecimpunctata howardi Barber, …

Forest edges enhance mate-finding in the European gypsy moth, Lymantria dispar
… A male release-recapture experiment using female-baited traps in fields, at forest edges, and in the forest interior showed that mate-finding was highest at forest edges, reduced in fields, and lowest within the forest interior. This suggests that forest edges and moderate habitat fragmentation …

1-(1H-pyrrol-2-yl)-1,2-propandione is a crucial pheromone component of the rare North American cerambycid beetle Dryobius sexnotatus
… study attests to the effectiveness of pheromone-baited traps in detecting rarely encountered species of cerambycids. It also provides further evidence that the pyrrole represents another conserved pheromone motif within the Cerambycinae.

Seasonal and diel periodicity of Cerambycid beetles in east-central Illinois: the potential for cross attraction
… periodicity was characterized with pheromone-baited traps equipped with a mechanism that rotated collection jars at programmable time intervals. Traps captured 1,134 beetles of eight species in three tribes of the Cerambycinae. The study strongly supported the hypothesis: 1) Species that …

Interbasin Transfer of Invasive Crayfish via Bait-Bucket Dumping
… of the northern half of Truman Reservoir using baited traps. I found crayfish at four of the 44 sites sampled: the northern crayfish (Orconectes virilis) and the White River crayfish (Procambarus acutus), a species not native to this reservoir. I used interviews of 162 local anglers to quantify …

Blending synthetic pheromones of cerambycid beetles to develop trap lures that simultaneously attract multiple species
… multiple species simultaneously. Pheromone-baited traps captured 1,358 cerambycid beetles, of which 1,101 (81.1%) belonged to three species in the subfamily Cerambycinae: Neoclytus acuminatus (F.), Neoclytus mucronatus (F.), and Xylotrechus colonus (F.). Beetles of these species were …

Behavioral Ecology and Associated Virology of Mosquito-Host Interactions in Southern California
… first demonstrated that mosquito captures at CO2-baited traps decreased most markedly with height above ground, and also decreased with distance from water at a riparian area but not at an open water source lacking a vegetated border. Birds might therefore prefer elevated nests or roosts to avoid …

Temporal variation in fruit-feeding forest butterfly communities in Sabah, Borneo.
… butterfly communities in Sabah, Borneo. Fruit-baited traps were used to sample butterflies in primary forest and forest that had been selectively logged 11-12 years previously in 1988 and 1989. Traps were hung 1-2m from the ground along four transects in primary and logged forest (8 km in …

Monitoring Abundance of Ips Bark Beetles and Determining Related Tree Mortality in Arkansas and Texas
… (Germar), was monitored with pheromone-baited traps in 2012 and 2013 in Arkansas and eastern Texas. Additionally, vehicle-based and comprehensive ground-based surveys were used to estimate and confirm the amount of dead and fading trees in each trapping site. Pine engraver beetles have …

Responses of fruit-feeding butterflies to selective logging in Sabah, Borneo
… rainforest of Sabah, Malaysia (Borneo). Fruit-baited traps were used to survey butterflies in unlogged forest and forest that had been selectively logged 10 - 12 years previously in 1988 and 1989. The study focused on butterflies in the sub-families Satyrinae, Nymphalinae, Morphinae and …

Spotted Wing Drosophila (Drosophila suzukii) in Arkansas: Winter Morphs, Wild Hosts, and Fungal Control
… that were darker and larger than flies caught in traps from June-August (2015-2017). SWD baited traps were set out from October 2017-May 2018 to see if and how late SWD appeared in Arkansas. Adults were caught until January 2018. Alternative fruit resources they used into the fall and winter …

The olfactory basis for attraction of the Bollworm helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) to host-plant flowers
… significant difference in H. armigera catches in traps with a standard 4-component T. erecta lure compared with unbaited traps over the whole season. Mean H. armigera catch per trap per night (both sexes) over the whole season in unbaited traps, floral odour traps, pheromone traps and light traps …

Impacts of selective logging on tropical butterflies in Sabah, Malaysia
… there was a relationship with sunshine. Fruit-baited traps were used to investigate vertical stratification of butterflies in unlogged forest from ground to canopy levels. A total of 542 individuals from 40 species were captured in traps. Low-level (2m) traps caught species with more restricted …

Evaluating the population control of invasive crayfish using removals and male sterilisation.
… using a combination of intensive trapping (baited traps and artificial refuge traps: ARTs) and the mechanical sterilisation and release of large males (Sterile Male Release Technique: SMRT) using both field studies (on the River Barle, Devon, Southern England) and laboratory-based …

The community ecology of a riverine turtle assemblage in the Tennessee River Gorge
… Tennessee River Gorge. Trapping methods included baited traps (hoop nets and fyke nets) and unbaited traps (fyke nets, basking traps, hand capture, and trammel nets). The relative abundance of generalist turtle species was consistently greater than that of more sensitive species during each study …

Bionomics of Culicoides (Diptera:Ceratopogonidae) in Virginia
… 1 or more of 14 different hosts used in animal-baited traps. Animals were restrained and exposed on a small platform. After 15 min the animals were covered with a collecting cage. Flies were aspirated from the traps and killed in 70% ethanol. Even though some preferences possibly were shown by …
