For the biological control of Ernnyis ello, an application of Bacillus thuringiensis (400-500 g/ha for aerial applications or 2-3 g/l of water for land applications), together with a surfactant with adherent properties, is recommended. When a hornworm population increase is foreseen due to the in...

Little is known about the inheritance of agronomic traits in cassava (Manihot esculenta Crantz). The vegetative multiplication of cassava allows cloning of individual genotypes, and separates environmental from genetic variation in the within-family variation. Knowing the magnitude of between- an...

Epistasis in cassava adapted to midaltitude valley environments
Cassava, one of the world's major food crops is grown throughout the tropical regions of the world. Cassava originated in the neotropics; it was introduced into West Africa from Brazil by slave traders in the 1500's, and taken to Asia during the 17th century. Consequently the greatest diversity o...

Cassava (Manihot esculenta Crantz) is an important commodity for industrial processes in tropical countries as one of the few alternatives to compete with imported maize (Zea mays L.). To maintain this competitiveness, cassava breeding needs to be as efficient as possible. This study provides one...

Amblystira machalana Drake (Chinche negro de encaje) es una plaga del follaje de la yuca, que se ha venido observando desde 1985 en diferentes partes de Colombia, Ecuador y Venezuela provocando daños en este cultivo. Varios trabajos se realizaron en el CIAT con el objeto de conocer su ciclo de vi...

Host plant resistance (HPR) to whiteflies is rare in cultivated crops. A literature search revealed that HPR research with the Bemisia tabaci/Bemisia argentifolii complex has increased considerably in recent years, but large-scale screening of a wide selection of genotypes is limited. At the Inte...
