World food shortages become more acute each year, and all too often, rodents are present to take their unwarranted share. To counter this, we must refine our rodent control methods to make them more efficient. To this end, correct bait selection is essential. Grain baits must be selected for purity and acceptability. Grain alterations must be carefully controlled, as well as any additives. Mult...

Proteomics researchers are constantly on the lookout for new and better ways to fractionate their samples since the mind-numbing complexity of virtually any proteome easily defeats the ability of even the most advanced mass spectrometers or other instruments to “see” all of the molecules in the sample. In this issue of Nature Chemical Biology, Weerapana et al. report new chemical tools for this...

Knowledge about the social behavior of sharks is a growing research field, but not many observations are available on interactions between pairs in presence passive surface bait and mainly related to aggregations. Between 2009 2018, Gansbaai, South Africa, 415 white were sighted, 525 surface-generated identified, exhibited by 169 different sharks. The mean sighting rate was 0.91 (range 0.18–1.5...

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 ...

In an enclosure-type study, I investigated the use of odor, auditory, and visual cues to enhance lithium-chloride (LiCl)induced prey aversion in coyotes (Canis latrans). Eight adult, male, wild-caught coyotes that killed 2 adult sheep during successive daily, 1 -hr trials were assigned to LiCland sodium-chloride (NaCl)-bait groups. The 4 LiCl-bait coyotes were sequentially presented with leg-of...

BACKGROUND Ecologists, fisheries scientists, and coastal managers have all called for an ecosystem approach to fisheries management, yet many species such as the American lobster (Homarus americanus) are still largely managed individually. One hypothesis that has yet to be tested suggests that human augmentation of lobster diets via the use of Atlantic herring (Clupea harengus) as bait may cont...

We successfully modified an existing method to investigate protein-protein interactions in the pathogenic bacterium Salmonella enterica serovar Typhimurium (Salmonella Typhimurium). This method includes (i) addition of a histidine-biotin-histidine tag to the bait proteins via recombinant DNA techniques, (ii) in vivo cross-linking with formaldehyde, (iii) tandem affinity purification of bait pro...

Information on toxic loading and piece-weight distribution are used to calculate an index of the number of baits which an animal must encounter and eat before the probability of death exceeds 99%. It is termed the 99% bait quality index (99BQI).The index shows that, on average, rabbits of median susceptibility to 1080 must find 4.2-5.4 unscreened carrot baits; possums of median susceptibility m...

On the southern coast of South Korea, dark-banded rockfish, sea bass, and red seabream are caught by single-line fishing. In particular, bass in Jeollanam-do region using gear with attached fishing hooks, such as long-line gear, live shrimp bait. The objective this study was to compare catch efficiency two types (naturally grown Shiba [Metapenaeus joyneri] cultured whiteleg [Litopenaeus vanname...
