This study aimed at an assessment of the potential of the egg parasitoid Telenomus isis (Polaszek) as a biological control agent of cereal stem borers. Therefore, the effects of temperature, host species, host age, and time of host deprivation on the development and the reproductive potential of ...

Many factors can severely affect beans during their growth cycle. Parasitic plants, such as Cuscuta epithymum and Cassytha filiformis, can reduce yields. Various environmental conditions including frost, extreme conditions of high or low MC, sudden changes in soil and air temp., and periods of in...
Muchos factores pueden afectar severamente el frijol durante su ciclo de crecimiento. Las plantas parasitas, tales como Cuscuta epithymum y Cassytha filiformis, pueden reducir los rendimientos.

The effects of temperature on conidial germination and susceptibility of adults of the desert locust, Schistocer cagregaria, to four isolates of Meta rhizium flovoviride were determined. In addition, the eff ects of inoculation method (topical or spray), spore carrie r (oil or wat er) and ambient...

Photoperiod screening has continued at CIAT-Palmira throughout 1984 using 18 h daylengths to delay flowering. Materials evaluated included lines from various EP and the germplasm collection and the results from previous screening efforts have been compiled into a list of photoperiod responses of ...
Durante 1984 continuo la seleccion por fotoperiodo en CIAT- Palmira utilizando longitudes del dia de 18 h para retardar la floracion. Los materiales evaluados incluyeron lineas de varios EP y la coleccion de germoplasma; los resultados de esfuerzos de seleccion anteriores se han compilado en una ...
