Abstract The American toad (Anaxyrus americanus) is a native insectivorous amphibian common in agricultural fields in eastern North America. Past research on this and related species suggests potential for positive or negative effects on pest populations, depending on the prevalence of intraguild predation.

Devouring the Invaders: The Racial‐Ecological Politics of the Chinese Crayfish Trade in Kenya
ABSTRACT This article examines entanglements of ecology, race, and foodways at Lake Naivasha in Kenya. Nonnative Louisiana red swamp crayfish (Procambarus clarkii), first introduced to Kenya in the 1960s, were once viewed as invasive but are now sought after as a delicacy among Kenya's Chinese community.

ABSTRACT Insect‐derived molecular cues can prime plant defences against herbivore attack. The genes that are sensitive to priming, and how their expression changes on the scale of days, have not been fully resolved. Moreover, priming may affect interactions with insects that are not the source of the priming cue.

SUMMARY Vigna unguiculata (L.) Walp. is a dryland legume crop, providing essential food and nutritional security for millions of people across the semi‐arid tropics, in Africa, Asia and Latin America. However, as a typical ‘orphan crop’, cowpea has long remained underrepresented in global genomic research to support crop improvement. Here, we conducted

ABSTRACT Cuticular waxes can form a hydrophobic barrier on aerial plant surfaces, which is essential for mediating plant‐environment interactions by providing protection against both biotic and abiotic stresses. In this study, a cuticular wax mutant (gl) was identified and characterised in Welsh onion (Allium fistulosum L.), exhibiting a functional ...

ABSTRACT Use of molecular markers has improved the analysis of genetic variation by eliminating environmental influences on genotype performance. The objective of this study was to assess the genetic diversity (GD) and population structure of 327 sweetpotato genotypes sourced from the major sweetpotato‐growing regions of Zimbabwe and from the ...

Plant pathogens as biocontrol agents of Cirsium arvense : an overestimated approach? [PDF]
Cirsium arvense is one of the worst weeds in agriculture. As herbicides are not very effective and not accepted by organic farming and special habitats, possible biocontrol agents have been investigated since many decades.

Preparation of alphacypermethrin and fipronil emulsifiable concentrates using different concentrations of the modified polytrisiloxane (QS-302) [PDF]
The present research aimed to enhance the efficacy of alphacypermethrin and fipronil insecticides formulated as an emulsifiable concentrate (EC) by adding varying concentrations of the modified polytrisiloxane (QS-302) as an adjuvant alongside the ...
