We have recently devised a method to quantify interactions between a membrane protein ("bait") and a fluorophore-labeled protein ("prey") directly in the live-cell plasma membrane (Schwarzenbacher et al. Nature Methods 5:1053-1060 2008). The idea is to seed cells on surfaces containing micro-patterned antibodies against the exoplasmic domain of the bait, and monitor the co-patterning of the flu...

Bait sprays containing the toxicant spinosad (GF-120) were applied to citrus groves in the Rio Grande Valley of Texas where Mexican fruit flies were detected in surveillance traps. The sprays were applied as a supplement to a continuous sterile insect release program. Sterile fly captures were 47-63% lower in the treated groves compared with control groves. Eight of 10 secondary pest population...

BACKGROUND It is known that cockroach allergen exposure is both frequent in inner-city homes and associated with asthma severity in children living in those homes. However, there have been few studies of interventions to reduce exposures in this setting. OBJECTIVE To evaluate the effect of short-term professional cockroach control and intensive cleaning on allergen concentrations. METHODS F...

Wildlife vaccination is increasingly being considered as an option for tuberculosis control. We combined data from laboratory trials and an ongoing field trial to assess the risk of an oral Mycobacterium bovis BCG vaccine and a prototype heat-inactivated Mycobacterium bovis preparation for Eurasian wild boar (Sus scrofa). We studied adverse reactions, BCG survival, BCG excretion, and bait uptak...

The efficacy of a 0.025% warfarin formulation against the lesser bandicoot rat (Bandicota bengalensis) was evaluated in groundnut and wheat crops in district Chakwal of the Pothwar Plateau, Pakistan. The baiting was started at early flowering stages of the respective crops using a broken rice formula (with additives) by placing bait stations near active burrow systems over a three weeks period ...

The control of rabies in raccoons (Procyon lotor) and striped skunks (Mephitis mephitis) in North America has been conducted mainly through aerial distribution of oral vaccine-baits. The effectiveness of the vaccine-bait used is therefore of prime importance for disease eradication. In a previous field comparison between the ONRAB(®) bait in the province of New Brunswick, Canada, and RABORAL V-...

The Asian needle ant (Pachycondyla chinensis Emery) is invading natural and disturbed habitats across the eastern United States. While recent studies document the impact of P. chinensis on native ecosystems and human health, effective control measures remain unknown. Thus, we evaluated the field performance of a hydramethylnon granular bait, Maxforce Complete Granular Insect Bait, dispersed in ...

Since 1984 pest control operatives in some inner-city areas in the U.K. have found that house mice have become increasingly difficult to control. Mice in these very localised areas have stopped taking rodenticide bait from bait containers, a phenomenon referred to here as behavioural resistance. We report here preliminary experiments designed to characterise the phenomenon more precisely by com...

The Argentine ant, Linepithema h1l1nile (Mayr), has proven to be a threat to native arthropod species in Haleakala National Park, Maui, HI, and is also a potential threat to the park's native flora. As it continues to expand its range, an effort has been undertaken to eradicate it, or at the least, control its spread. The 1st part of this effort focused on finding a bait carrier for subsequent ...

The invasive Argentine ant, Linepithema humile (Mayr), has become a worldwide problem capable of inflicting significant ecological and economic injury on urban, agricultural, and natural environments. The mobility of this pest ant has long been noted, rapidly moving nests to new food resources and then away as resources are depleted. This ant, like many pest ant species, has a special affinity ...
