Interbasin Transfer of Invasive Crayfish via Bait-Bucket Dumping
… rusty crayfish were discovered in Missouri bait shops, but at present no established populations in Missouri lakes have been reported. The purpose of the current study was to assess the risk of colonization by rusty crayfish and other non-native crayfish into a lake with high fishing …

Environmental Influences on Subterranean Termite Foraging Behavior and Bait Acceptance
… more likely to discover subterranean baits connected by physical guidelines than freestanding baits under both laboratory and field conditions. In the laboratory, subterranean termites built significantly longer tunnels adjacent to cellulosic guidelines than plastic guidelines. In the …

Exploitation and biology of the bait organism Callianassa kraussi Stebbing (Crustacea: Decapoda: Thalassinidae) in Langebaan Lagoon
… spp.) in Langebaan Lagoon, primarily for bait collecting, were assessed using field experiments and observations. Langebaan Lagoon has been a proclaimed National Park for 20 years and a proclaimed Marine Protected Area since 2000. The area is zoned for different human uses, about one third …

Estimating Black Bear Population Size, Growth Rate, and Minimum Viable Population Using Bait Station Surveys and Mark-Recapture Methods
We initiated bait station surveys for black bears in southwestern Virginia in 1999. Bait station surveys are intended to be used as an index to follow bear population trend over time. We compared the bait station visitation (black bear visitation) to black bear harvest and mast surveys 1999 = 2002. …

Using benthic microalgae as an indicator of recreational disturbance associated with bait collection and trampling in Langebaan Lagoon, South Africa
… from recreational activities, including bait harvesting and associated trampling. Many studies have quantified the impact of these activities on the benthic environment, with few dedicated to understanding microalgal responses. However, this study utilized a rapid, optical tool …

Experimental work with bait traps for the control of the codling moth, Carpocapsa pomonella, and the oriental fruit moth, Grapholitha molesta
Best results were obtained with syrup baits when diluted 1 part syrup to 20 parts of water. Tin traps were most satisfactory when painted inside and out with aluminum paint. A syrup bait was effective for an average of 5 weeks without change when water was added after the first two weeks. The cost …

The ecological effects of collecting Callianassa kraussi Stebbing and Upogebia africana (Ortmann) for bait : impacts on the biota of an intertidal sandflat
… kraussi and the mudprawn Upogebia africana for bait were assessed at Langebaan Lagoon, South Africa, through surveys, observations and long-term experimental analyses. While only a small proportion of the prawns is removed from the lagoon annually, amounting to no more than 0.01 for the total …

Assessing the effects of trampling and bait-collecting on population, morphological and reproductive metrics of a key ecosystem engineer in Langebaan Lagoon
… human-related disturbances such as intense bait collection and trampling, that compromise ecosystem resilience and functionality. Research on how human disturbance impacts keystone species, such as the endobenthic sandprawn Kraussilichirus kraussi, an important ecosystem engineer, has proven …

Effects of harvesting aquatic bait species from a small West Virginia stream (part I); and, Crayfish marking with fluorescent pigment (part II)
Fluorescent granular pigment sprayed with 738 g/cm² (105 p.s.i .) for 5, 10, 20 second intervals was used to mark crayfish in a laboratory study. The pigment was retained by 100% of the unmolted crayfish 35 days after treatment and by 65% of the crayfish 56 days after treatment. Crayfish which were …

Assessing the Live Bait Industry and the Ecological Status of Invasive Cyprinodontiformes (Sheepshead minnow: Cyprinodon variegatus and Gulf killifish: Fundulus grandis) in Texas Streams
… been introduced into inland Texas waters via bait-bucket releases and have caused native populations of their inland congeners to decline. While I did not find evidence that either species were being sold in inland shops, bait industry experts did reveal other potentially harmful species, …

The response of German cockroaches to commercial toxic baits and their potential to develop resistance
… germanica, were exposed to four different toxic baits. The baits used were Roach Ender, Whitmire gel bait (not commercially available), Stapleton’s Magnetic Roach Food and Baygon. For each bait, strains varied in respect to bait consumption, percent bait eaten and mortality. Selection experiments …

Seasonal abundance and host preference of Culicoides in Virginia: with emphasis on the ecology of Culicoides variipennis (Diptera: Ceratopogonidae)
… species were collected in the BLTs and 17 in the bait traps. Culicoides biguattatus, C. obsoletus, C. stellifer, C. varipennis, and C. venustus were the most abundant species collected in both traps. Eight new host records were reported in this study. The drop trap collected more midges than did …
