Data analysis with ordinal and interval dependent variables: examples from a study of real estate salespeople [PDF]

This paper re-examines the problems of estimating the parameters of an underlying linear model using survey response data in which the dependent variables are in discrete categories of ascending order (ordinal, as distinct from numerical) or, where they ...

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

Pest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Genotype‐by‐environment interaction informs selection for seed physiological quality and stink bug tolerance in soybean under pest management contrasts

Pest Management Science, EarlyView.
Genotype‐by‐environment interaction shaped soybean seed stability under contrasting insecticide regimes. Seed longevity emerged as a stable, management‐relevant trait under pest pressure. High‐pressure, no‐insecticide conditions improved discrimination of tolerant genotypes for integrated pest management deployment.

Legal Status and U.S. Farm Wages

Using National Agricultural Workers Survey data, we estimate U.S. farm worker wage differentials by legal status. In order to adequately correct sample selection bias, we develop a Heckman-type two-stage method with an ordered probit model in the first ...

Perceptions, challenges and determinants of management strategy choices for combating fall armyworm (Spodoptera frugiperda) infestation in Ghana

Pest Management Science, EarlyView.
Despite high awareness of fall armyworm, a significant gap remains in the use of sustainable and effective control measures. Farmers predominantly perceive synthetic pesticides as ideal despite studies highlighting botanical and traditional methods as more sustainable.

Synergistic transition from type‐I‐like to type‐II‐like symptomology in a pyrethroid mixture and its impact on knockdown–mortality relationships in Musca domestica L

Pest Management Science, EarlyView.
In the present study, relationship between knockdown and mortality of insecticides was examined against the adult female housefly, Musca domestica. Type‐I pyrethroid insecticides showed a weak linkage, as early knocked down flies did not always result in mortality, while type‐II pyrethroids and organophosphates exhibited strong correlation between the ...

Assessing the potential for insecticide cross‐resistance to a novel insecticide in the Colorado potato beetle (Leptinotarsa decemlineata) using phenotypic and transcript expression analysis

Pest Management Science, EarlyView.
Phenotypic and transcriptional responses to imidacloprid and isocycloseram were examined across U.S. populations of the Colorado potato beetle, showing evidence of phenotypic cross‐resistance alongside population‐level variation in detoxification gene expression.
