Insecticides outweigh rye cover crop in triggering secondary pest outbreaks

Pest Management Science, EarlyView.
Insecticides outweigh rye cover crop in triggering secondary pest outbreaks. Zeus Mateos‐Fierro*, Ashley Leach, Ian Kaplan. Spider mite and melon aphid outbreaks are enhanced with broad‐spectrum insecticides, while natural enemies are reduced. However, rye cover crop has little effect on either pest or natural enemy populations.

Rescue of early heart-shaped embryos and plant regeneration of Phaseolus polyanthus Greenm. and Phaseolus vulgaris [PDF]

Biotechnologie, Agronomie, Société et Environnement, 1999
In order to improve plant recovery from early heart-shaped Phaseolus embryos, several refinements were made to the embryo rescue technique developed previously in our laboratory. Using Phaseolus polyanthus Greenm. and Phaseolus vulgaris L.

Control of two sucking insect pests, a whitefly (Bemisia tabaci) and a thrips (Frankliniella occidentalis), infesting hot peppers by spraying LDH‐formulated dsRNA

Pest Management Science, EarlyView.
A vacuolar type ATPase subunit B (vATPase‐B) gene is identified and expressed in the midgut of Bemisia tabaci and Frankliniella occidentalis. The double‐stranded RNA (dsRNA) specific to vATPase‐B was expressed in hot peppers by virus‐induced gene silencing (VIGS) and killed both whitefly and thrips.

Removal of antinutritional factors from bean (Phaseolus vulgaris L.) seeds [PDF]

Biotechnologie, Agronomie, Société et Environnement, 1999
Phytohemagglutinin and the lectin-related proteins present in bean seeds are toxic to monogastric animals and lower the nutritional value of beans. Since these antimetabolites are present in substantial amounts, a breeding program aimed to the removal ...

Review: The Potential of the Common Bean (Phaseolus vulgaris) as a Vehicle for Iron Biofortification

Nutrients, 2015
Common beans are a staple food and the major source of iron for populations in Eastern Africa and Latin America. Bean iron concentration is high and can be further increased by biofortification.

Modeling of suitable geographic areas for Striacosta albicosta in corn and dry bean crops under climate change scenarios

Pest Management Science, EarlyView.
In recent years, the occurrence of the pest Striacosta albicosta has expanded from western to eastern North America. This study identified areas with suitable climatic conditions for the establishment of this pest. Our findings may guide government agencies to prevent the spread of this pest to new areas.

Study of the early abortion in reciprocal crosses between Phaseolus vulgaris L. and Phaseolus polyanthus Greenm [PDF]

Biotechnologie, Agronomie, Société et Environnement, 2002
The causes of early embryo abortion in the reciprocal crosses between Phaseolus vulgaris L. and Phaseolus polyanthus Greenm. were studied. Methacrylate resin sections, 2 micron meter thick, of 2 to 6 day-old hybrid seeds were used to examine the stage of
