Field experiments on the control of aphis-transmitted virus diseases of Hyosujamus Niger

open access: yes, 1937
1 Aphis infestation of the first‐year's growth of Hyoscyamus niger grown as a biennial crop, was reduced by spraying with a solution of nicotine and soft soap for the first 8 or 9 weeks. 2 The greatest effect was obtained by spraying at weekly intervals,

Evaluation of Rhodamine B as a Biomarker for Raccoons

open access: yesHuman-Wildlife Interactions, 2017
The USDA/APHIS/Wildlife Services (WS) oral rabies vaccination program uses tetracycline, a broad-spectrum antibiotic and relatively reliable biomarker, to quantify vaccinebait uptake by raccoons (Procyon lotor).

Sublethal herbicide exposure alters cotton susceptibility to aphid infestation

open access: yesPest Management Science, EarlyView.
Sublethal herbicide exposure altered cotton susceptibility to aphids. Aphid severity was highest when applications occurred at early vegetative stages and declined as the crop matured. In glasshouse, herbicide effects were dose‐dependent. Abstract BACKGROUND Herbicides remain vital tools for weed control, yet their effects can extend beyond weeds to ...

Bovine Tuberculosis in a Nebraska Herd of Farmed Elk and Fallow Deer: A Failure of the Tuberculin Skin Test and Opportunities for Serodiagnosis

open access: yesVeterinary Medicine International, 2011
In 2009, Mycobacterium bovis infection was detected in a herd of 60 elk (Cervus elaphus) and 50 fallow deer (Dama dama) in Nebraska, USA. Upon depopulation of the herd, the prevalence of bovine tuberculosis (TB) was estimated at ∼71–75%, based upon ...

Effects of timed LED regimes on tomato plant traits, performance of two‐spotted spider mites, and predatory mites (Phytoseiulus persimilis)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2300-2311, April 2025.
Light‐emitting diode (LED)‐based treatments for enhancing crop production and pest management have primarily focused on continuous treatments. This study, using Tetranychus urticae and Phytoseiulus persimilis, demonstrates that the timing of LED supplementation is crucial for designing integrated pest management strategies that improve both plant ...

Aggregation and the transformation of counts of Aphis fabae Scop, on beans

open access: yes, 1970
In several sets of counts of Aphis fabae colonies on bean stems, obtained with different sampling methods, variance was always proportional to the same power of the mean; s2=amb where b= 1.72 and a differed by different sampling methods.

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
