Pests may affect bean production, before and after harvest. (1) Those that attack bean seedlings are the seed corn maggot which causes poor germination and deformed seedlings. The most common genera of cutworms include Agrotis, Feltia and Spodoptera; white grubs and crickets also attack the seedl...
Las plagas pueden afectar la produccion de frijol, antes y despues de la cosecha; las perdidas varian de una region a otra, debido a las diferencias que existen en las fechas de siembra, var, y practicas culturales.

El Lorito verde (Empoasca kraemeri Ross y Moore) y su control [conjunto audiotutorial]
An expt. to study the background soil effects associated with var. resistance in bean pest populations, virus incidence and yield was carried out at the Centro Internacional de Agricultura Tropical (CIAT), Palmira, Colombia from Jan.-March, 1978. The effect of the treatments and of the var. on Em...

The effect of maize/bean intercropping on Empoasca kraemeri population and damage, populations of other phytophagous insects, the parasitic action of Anagrus sp. on E. kraemeri, ambient temp. and RH, light intensity, and bean leaf temp. was observed. Two planting dates and 3 maize densities in 2 ...

Resistance of 360 var. of Phaseolus vulgaris to Empoasca kraemeri was evaluated in the greenhouse. Subsequent field evaluations were made of 30 promising var. when 30 days old. Seedlings in the greenhouse were infested with field-collected adults for 3 days, and resistance to 1st generation nymph...

Comparison of greenhouse and field resistance of bean varieties to Empoasca kraemeri (Homoptera Cicadellidae)
Tropical agroecosystems constitute diversified systems with crops arranged in polycultural patterns. Weeds are important components of these systems and condition insect diversity and stability. In an attempt to gather experimental evidence as a basis for tropical pest management strategies, 9 fi...
