We aimed to develop alternative fishing gear for catching the common octopus, to decrease the use of bait and operating costs in comparison to commercial net pots. A tubular-type pot was designed, and behavioral responses of the common octopus were experimentally monitored in tank and replicated 10 times to compare fishing performances between 300 experimental and 300 commercial net pots in the...

Invasive rodents (primarily Rattus spp.) are responsible for loss of biodiversity in island ecosystems worldwide. Large-scale rodenticide applications are typically used to eradicate rats and restore ecological communities. In tropical ecosystems, environmental conditions rapidly degrade baits and competition for baits by non-target animals can result in eradication failure. Our objective was t...

We analyzed 1950s survey data with generalized estimating equations (GEEs) to quantify factors that influence the rate that bait is lost from pelagic longlines. Hook depth, bait species, local tuna abundance, and the timing of longline operations strongly influenced loss rates. Loss rates increased with tuna abundance and soak time. They declined with hook depth and were low for firm-bodied bai...

We examined the efficacy of termiticidal baits comprised of powdered acellulose and a mineral insecticide, cryolite crystals, in laboratory bioassays against pseudergates ofEastern subterranean termites [Reticulitemzesjavipes (Kollar)]. The influence of cryolite crystal size [0 (control), 0.2, and 20 pm diameter particles] on the overall mortality of termites consuming the bait was determined i...

Two insecticide formulations containing the naturalyte insecticide spinosad, GF-120 Fruit Fly Bait and SpinTor 2 SC, were compared for control of apple maggot, Rhagoletis pomonella (Walsh), and blueberry maggot, Rhagoletis mendax Curran. In 2002 and 2003, larval infestation in blueberries and apples was signiÞcantly lower in plots treatedwithGF-120 (spinosad bait) or SpinTor than in untreated c...

Diphacinone treated oat groats were effective in reducing populations of California ground squirrels (Spermophilus beecheyi) by more than 84%. Two concentrations of active ingredient (0.005% and 0.01%) were compared, as well as two application methods: spot baiting and bait stations. Squirrel activity on test plots was assessed before and after bait applications using visual counts and active b...

Toxicant coated grain-based baits are widely used to control rodent pests throughout the world, but where alternative food sources are available, bait acceptance and efficacy are often less than optimal. In an attempt to develop baiting strategies to increase bait acceptance and efficacy of zinc phosphide-coated baits, a sugar-enhanced rolled oat based zinc phosphide bait was evaluated. With pr...

Background In the Philippines, traditional mass dog vaccination campaigns have only achieved limited and transient success in dog rabies control, mainly because a large segment of the dog population is not accessible for traditional parenteral vaccination. Oral vaccination of dogs has been suggested as a supplementary method to increase the overall vaccination coverage of the dog populations in...
