To investigate the potential for mortality or sublethal effects in the tree weta (Hemideina crassidens) as the result of exposure to baits used for rodent control, and the potential secondary hazard to non-target species, captive weta were offered Ditrac® wax block bait containing the anticoagulant diphacinone. Bait consumption was recorded daily for the first week and then weekly. Weta were sa...

The efficacy of bistrifluron termite bait was evaluated using in-ground bait stations placed around Coptotermes lacteus mounds in south-eastern Australia during late summer and autumn (late February to late May 2012). Four in-ground bait stations containing timber billets were placed around each of twenty mounds. Once sufficient numbers of in-ground stations were infested by termites, mounds we...

Bait stations represent an environmentally friendly attract-and-kill approach to fruit fly population suppression. Recently a novel, visually attractive, rain-fast bait station was developed in Hawaii for potential use against multiple species of pestiferous fruit flies. Here, we compared the efficacy of GF-120 NF Naturalyte Fruit Fly Bait applied either as foliar sprays or onto bait stations i...

Current efforts to develop oral rabies vaccine baits for domestic dogs are reviewed and new materials (bait matrices, additives, vaccine containers, vaccine modification) for improving bait acceptance and vaccine delivery are suggested. Methods that have been used to evaluate the food or bait preferences of confined and free-ranging animals are summarized, as are the guidelines for bait distrib...

The efficacy of liquid deltamethrin was evaluated for controlling fleas on golden-mantled ground squirrels, Spermophilus lateralis, and chipmunks, Tamias amoenus and T. senex. A host-targeted bait tube was modified to deliver insecticide to visiting rodents during a seven-week trial conducted in the Southern Cascade Mountains of northern California. A single deltamethrin treatment with one repl...

Effective delivery of vaccines and other pharmaceuticals to wildlife populations is needed when zoonotic diseases pose a risk to public health and natural resources or have considerable economic consequences. The objective of our study was to develop a bait-distribution strategy for potential delivery of oral bovine tuberculosis (bTB) vaccine to white-tailed deer (Odocoileus virginianus) where ...

Three species of fruit flies cause serious damage to cucurbit crops on Reunion Island: Bactrocera cucurbitae (Diptera: Tephritidae) (Coquillett 1899), Dacus ciliatus (Loew 1901), and Dacus demmerezi (Bezzi 1917). To control them, a program of agroecological management of cucurbit flies has been implemented based on the application of Synéis-appât, especially spot sprays on corn borders. However...

The sterile insect technique (SIT) is used to control wild Mediterranean fruit fly introductions in California and Florida in the U.S. In the past, bait sprays containing malathion proved invaluable in treating new outbreaks or large populations before the use of SIT. Recently, a spinosad protein bait spray, GF-120, has been developed as a possible alternative to malathion, the standard insecti...

Control of ants using baits of low toxicity cannot be effective without knowledge of bait distribution patterns and bait station densities, which are determined by ants' foraging activities. Furthermore, the success of toxic baits also depends upon attractiveness of bait carriers. Here, we assessed ground and vine foraging activity and food preferences for the three ant species ( Linepithema hu...

Key to the effectiveness of fruit fly (Diptera: Tephritidae) suppression efforts using insecticidal bait sprays is the determination of how long the bait remains attractive to adult flies after application. Using a comparative approach, field studies were conducted in commercial papaya (Carica papaya L.; Brassicales: Caricaceae) orchards in Hawaii with the goal of quantifying the response of Ba...
