Non-target-site resistance to ALS inhibitors in waterhemp
… amino acid biosynthesis, and is the target site of five families of herbicides referred to as ALS inhibitors. Waterhemp (Amaranthus tuberculatus) is considered one of the most problematic weeds in the Midwest cropping region. The evolution of herbicide resistance and multiple …

Assessing the effects of anticoagulant rodenticides on non-target fish species
… USA have used first generation AR, diphacinone (DPN), for pest and rodent control. Rodent populations, found on the Hawaiian Islands, have not only caused the extinction small shorebird and plant populations but have also been in direct competition for resources. ARs, in the form of a bait …

Evaluation of Novel Carbamate Insecticides for Neurotoxicity to Non-Target Species
… selected for further neurotoxicity testing in non-target organisms. For commercial carbamate insecticides, the IC50 varied from 9.1 nM to 2,094 nM. For the novel carbamate insecticides, it varied from 58 nM to 388,800 nM. Based on IC50 data from previous work on A. gambiae, the selectivity …

UNDERSTANDING NON-TARGET INSECTICIDE IMPACTS AND OPPORTUNITIES FOR BIOLOGICAL CONTROL IN FIELD CORN
… and a slug predatory carabid species may exert non-consumptive effects on a pest slug. Finally, I determined that a predatory lady beetle species is likely less susceptible to RNAi oral exposure in the adult stage. However, RNAi may still pose risks to predators via trophic exposure. My work …

Impact of mustards (Brassicaceae) grown as cover crops on non-target arthropod communities
… of mustard varieties grown as cover crops on non-target arthropod communities and diversity were investigated in 2008. The abundance of carabid beetles, collembolans, and mites were monitored before, during, and after the seeding, growth, and incorporation of two mustard varieties (‘Tilney’ …

Combining Chemometrics and non-target GC-IMS gas phase analysis for improved bioprocess monitoring
… VOC measurements in conjunction with chemometric non-target screening techniques as a soft sensor for bioprocess monitoring. In consequence of the lack of suitable software, a Python package for the multivariate analysis of GC IMS data was developed and subsequently published as open-source …

Efficiency of Two Black-tailed Prairie Dog Rodenticides and Their Impacts on Non-target Bird Species
<p>In 1983 zinc phosphide, strychnine with prebait, and strychnine without prebait were applied to black-tailed prairie dog (Cynomys ludovicianus) colonies in west-central South Dakota. Short-term (4 days later) and long-term (1 year later) poison efficiency and impact (short-term and long-term) on …

Non-Target Emotional Stimuli Must Be Highly Conspicuous in Order to Break through the Attentional Blink
In the attentional blink (AB), the second of two targets (T2) separated by a short lag in a rapid serial visual presentation (RSVP) stream is difficult to report. The AB is typically thought of as a top-down effect because it is triggered when the first target (T1) matches a search template. …

Do Mosquito Pesticides Harm Their Natural Enemies? Ecological Impacts and Non-Target Effects of Larvicides on Mosquito Predators
<p>Larvicides are chemicals used to kill juvenile mosquitoes. When applied to an area, other aquatic organisms are exposed to these chemicals. The removal or impairment of top insect predators could be beneficial to mosquito populations once harmful pesticide levels dissipate. Two common larvicides …

Population ecology of the red admiral butterfly (Bassaris gonerilla) and the effects of non-target parasitism by Pteromalus puparum
… generalise on what determines the magnitude of non-target effects by arthropod biocontrol agents, this being only the second study to quantify effects at a population level. However, in this case retrospective analysis has shown that the impact of non-target parasitism by P. puparum on B. …

Molecular docking and geographical information systems as tools to assess the potential impact of veterinary medicines on non-target organisms and the environment
… lethal effects when they come into contact with non-target organisms. VMs enter the environment in mixtures, potentially having additive effects. Traditional ecotoxicology tests are used to determine the lethal and sometimes reproductive effects on freshwater and terrestrial organisms. However, …

The Influence of Age and Sterol-Inhibiting Fungicides on the Sterol and Steryl Ester Composition of SIF Sensitive and Tolerant Non-Target Chlorella Species
… under changing environmental conditions. Non-target algae species possess sterol synthesis pathways that are affected by a range of SIFs. One of the main objectives of the current study was to determine the reason for the observed sensitivity of C. fusca and the tolerance of C. kessleri to …

Parasitism of Scarabaeidae by Parasitoid Flies in British Columbia and Western USA: Informing Biological Control Programs Against Popillia japonica with Crowd-sourced Records of Non-target Scarab Beetles
Following the 2023 Port Coquitlam introduction of the parasitoid fly Istocheta aldrichi to suppress a population of the invasive scarab beetle Popillia japonica, I used crowd-sourced online data (44,200 observations in BC and Western USA) to determine: scarab species occurrence; which species may …

Reassessing the Power of One Reinforcer with an Evaluation of Learning Histories
… a single conditioned reinforcer delivered for a non-target behavior during shaping following a period of time without reinforcement (Hunter & Rosales-Ruiz, 2019). Findings suggested that the non-target behavior consequated with the conditioned reinforcer persisted into a 1-min extinction phase at …

FATE, TRANSPORT, AND MIXTURE TOXICITY OF TRANSGENIC BACILLUS THURINGIENSIS CORN (ZEA MAYS) AND ASSOCIATED INSECTICIDES
… concentrations could be causing effects to non-target species. The Cry1Ab proteins persisted only during the corn growing season in soil, runoff water and sediment with the highest concentrations measured during pollination. Clothianidin was detected in all matrices and remained persistent …

Teaching tactual discrimination of braille characters to beginning braille readers
… characters into training sets in which the target and non-target stimuli in the comparison arrays were initially maximally different in terms of the number of dots comprising each character. As participants mastered these discriminations, we then increased the similarity between target and …

Habit Preferences and Fidelity in the Cotesia Flavipes Complex (Hymenoptera: Braconidae): Current Preferences and the Potential for Change Through Learning and Selection
… to increasing the probability of controlling a target pest, and to decreasing the possibility of injuring non-target hosts. Here I suggest that testing habitat preference can help predict host ranges of insect parasitoids, and I present the results from tests of three congeneric braconid …

Development of a 16S rRNA gene sequence as a biomarker specific to the gastrointestinal tract and feces of swine based on suppressive subtractive hybridization
… for swine fecal contamination. Swine (n=8) and non-target fecal samples (n=23) were collected in Morgantown, WV and the surrounding area. Additional soil (n=2) and lagoon (n=3) samples impacted with swine manure and soil (n=3) samples from areas not expected to be impacted by swine manure were …
