The general objectives of CIAT's bean entomology program are mentioned. The 1st priority has been given to var. resistance as an ideal pest control method. At CIAT's headquarters (Palmira, Colombia), studies are conducted on Empoasca kraemeri, mites, and storage insects; var. resistance to Apion ...
Se mencionan los objetivos generales del programa de entomologia de frijol del CIAT. La mayor prioridad se ha dado a la resistencia var. como metodo ideal de control de plagas. En la sede principal del CIAT (Palmira, Colombia) se adelantan estudios con Empoasca kraemeri, acaros e insectos del fri...
Pests may affect bean production, before and after harvest. 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 seedling...
The biology, damage caused, and control (cultural, chemical, and var. resistance) of the following insect pests attacking bean plant foliage are described: chrysomelids, Empoasca kraemeri, Epilachna varivestis, Trichoplusia ni, Bemisia tabaci, aphids, Tetranychus spp. Polyphagotarsonemus latus, A...

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. (1) Entre las que atacan el frijol: mosca de la semilla (Hylemya cilicrura), la c...

Significant advances in increasing tolerance to the leafhopper Empoasca kraemeri Ross & Moore in common bean have been obtained using a new breeding scheme where yield under leafhopper attack is the principal selection criterion in the evaluation of progenies. However, to further refine this bree...

Development of an appropriate breeding scheme for tolerance to Empoasca kraemeri in common bean
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 objectives of CIATs Entomology Program are: (1) the survey and identification of insect and mite species in L.A.; (2) establishment of the economic importance of pest species in terms of yield decrease and their geographic distribution; (3) evaluation of cv. for their resistance to determined...
