A comparison of pitfall traps with bait traps for sampling leaf litter ants was studied in oak-dominated mixed forests during 1995-1997. A total of 31,732 ants were collected from pitfall traps and 54,694 ants were collected from bait traps. They belonged to four subfamilies, 17 genera, and 32 species. Bait traps caught 29 species, whereas pitfall traps caught 31 species. Bait traps attracted o...

Laboratory and field trials were performed to evaluate the attractiveness and efficacy of commercial baits (cyantraniliprole; methomyl + (Z)-9-tricosene; dinotefuran + (Z)-9-tricosene; imidacloprid granular + (Z)-9-tricosene; and imidacloprid liquid + (Z)-9-tricosene). In choice tests; flies were most attracted to cyantraniliprole bait > dinotefuran + (Z)-9 > methomyl + (Z)-9 bait > imidaclopri...

In many areas of the world, only 30 to 50% of dogs are vaccinated against rabies. On some US Indian Reservations, vaccination rates may be as low as 5 to 20%. In 2003 and 2004, we evaluated the effectiveness of commercially available baits to deliver oral rabies vaccine to feral and free-ranging dogs on the Navajo and Hopi Nations. Dogs were offered one of the following baits containing a plast...

The enhancement of bait for the control of grass-cutting ants was investigated using two species of grass-cutting ant, Atta bisphaerica (Forel) and Atta capiguara (Gonçalves) (Hymenoptera: Formicidae). Bait was applied in loose piles to obtain a direct relationship between ant attraction and bait harvest. Enhancement with alarm pheromone compounds significantly increased the attractiveness and ...

Baits containing brodifacoum rodenticide were aerially applied to eradicate invasive black rats from Palmyra Atoll, an important biodiversity center. Bait application must be sufficient to be effective, while minimizing environmental hazards by not exceeding designated label rates, prompting our bait density assessments for two aerial drops. With few physical or human resources on this remote, ...

This study assessed the cost and effectiveness of a building-wide cockroach integrated pest management (IPM) program compared with bait alone treatment in public housing. In total, 12 buildings (66 apartments) were treated and monitored for cockroach infestations over 7 mo. The buildings were divided into two groups: bait treatment and IPM. Apartments in the bait alone group were treated with M...

Major causes of failure of aerial poisoning operations against possums identified were: sublethal toxic loading, undersize sublethal baits, nonlearned behavioural aversion to 1080, and failure to encounter bait. Dislike of bait was not a major cause of failure. Progress has been made towards solving these problems, but failure to encounter bait remains a likely major reason for possums survivin...

Using a quarterly (3-mo)monitoring andbait-replenishment interval, 122 subterranean termite colonies throughout the United States were baited with a reÞned cellulose bait matrix containing 0.5% novißumuron. All colonies were eliminated in less than 1 yr after initiation of baiting as determined by long-termmonitoring and geneticmarkers. Sixty-three percent of the colonies were eliminated during...

The insecticidal activity of a cockroach gel bait containing a chitin synthesis inhibitor, noviflumuron, was evaluated using laboratory and field strains of the German cockroach, Blattella germanica (L.). Noviflumuron gel bait (0.01-5 mg g(-1)) caused > or = 90% nymphal mortality to laboratory and field strains of B. germanica in choice tests after 11 and 19 days of continuous exposure respecti...

Hunting is the primary tool for managing white-tailed deer (Odocoileus virginianus) populations. Effectiveness of hunting in suburban areas may be reduced due to limited hunter access to small properties, firearms-discharge laws, and public safety concerns. In Connecticut, USA, hunting over bait on private land was recently legalized to increase harvest opportunities. Our objective was to asses...
