Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Influence of Epicuticular Physicochemical Properties on Porcine Rotavirus Adsorption to 24 Leafy Green Vegetables and Tomatoes. [PDF]

PLoS ONE, 2015
Foodborne diseases are a persistent problem in the United States and worldwide. Fresh produce, especially those used as raw foods like salad vegetables, can be contaminated, causing illness. In this study, we determined the number of rotaviruses adsorbed

In vivo chemical and structural analysis of plant cuticular waxes using stimulated Raman scattering microscopy. [PDF]

, 2015
The cuticle is a ubiquitous, predominantly waxy layer on the aerial parts of higher plants that fulfils a number of essential physiological roles, including regulating evapotranspiration, light reflection, and heat tolerance, control of development, and ...

Evaluating the efficacy of tagging adhesives for insect tracking

Agricultural and Forest Entomology, EarlyView.
Two‐part epoxy resin delivered the strongest RFID tag adhesion on carabid beetles, exceeding polyvinyl acetate, cosmetic latex and cyanoacrylate adhesives. Adhesive performance was consistent across Harpalus, Leistus and Poecilus; species effects were non‐significant, supporting a broadly applicable protocol for carabid RFID tagging studies.

Ultrastructure of Epicuticular Wax in Canola

Zeitschrift für Naturforschung C, 1989
Ultrastructure of the epicuticular wax of four commercially grown Canadian cultivars of canola (Brassica campestris cvs. Tobin and Candle, B. napus cvs. Altex and Westar) was investigated. Freeze-drying and air-drying methods of specimen preparation for scanning electron microscopy were compared.

Ontogenic variations in n-alkanes during somatic embryogenesis of flax (Linum usitatissimum L.) [PDF]

, 2001
Hypocotyl segments of flax seedlings germinated in vitro, were used to induce indirect somatic embryogenesis on solid medium. The composition and distribution of n-alkanes in flax tissues collected at different developmental stages were studied by GC and

Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

Archaeometry, EarlyView.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.

Efficacy of Zeolite and Kaolin in the Control of Cacopsylla pyri (L.) (Hemiptera: Psyllidae) and Compatibility With Its Natural Antagonist Anthocoris nemoralis (Fabricius) (Hemiptera: Anthocoridae)

Journal of Applied Entomology, EarlyView.
ABSTRACT The pear psyllid Cacopsylla pyri is a major pest of European pear orchards, responsible for significant yield losses. Its management is increasingly challenged by restrictions on synthetic active ingredients, resistance development, and the shift towards sustainable production systems.
