Natural Hybridization of Phaseolus vulgaris L. × Phaseolus coccineus L.1

Journal of the American Society for Horticultural Science, 1970
Abstract Frequency of natural hybridization of P. vulgaris and P. coccineus was observed over two seasons. Natural hybridization ranged from zero to 6.79%, and was dependent upon parental combination.

Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

Environmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

Food without fire: Environmental and nutritional impacts from a solar stove field experiment

American Journal of Agricultural Economics, EarlyView.
Abstract Over 80% of the population in rural Sub‐Saharan Africa relies on biomass cooking fuel, a substantial source of anthropogenic greenhouse gases. We use a field experiment in Zambia to investigate the impact of solar stoves on biomass fuel use and cooking habits.

Competitive Interactions Between Generalist Predators and Their Effects on Shared and Non‐Shared Pests in a Greenhouse Crop

Entomologia Experimentalis et Applicata, EarlyView.
Orius laevigatus engages in unidirectional intraguild predation on Transeius montdorensis. Despite this, both predators coexisted and suppressed the shared thrips prey. Aphids, a non‐shared prey, were effectively controlled by O. laevigatus even when its population was limited due to intraguild predation. T.

Development and Reproduction of Nesidiocoris tenuis Reuter (Heteroptera: Miridae): The Effect of Temperature, Origin and Food

Entomologia Experimentalis et Applicata, EarlyView.
Nymphal development took longer at 25°C than 30°C, and the Greek N. tenuis population developed more slowly than the commercial population. Nymphs clearly preferred E. kuehniella eggs over Artemia sp. cysts when both were offered equally. Egg production increased at 30°C, while female longevity declined.

Inducible tomato defences persist in detached leaves, despite differential plant variety and gene‐dependent expression

Ecological Entomology, EarlyView.
Short‐ and long‐term expression of PPO‐D, PI‐IIc and PR‐1a were assessed in intact plants and detached tomato leaves of two varieties infested with Tetranhycus urticae. Tomato defences were induced in both intact and detached leaves, but the induction levels varied with plant variety and gene assessed.
