Evaluation of host-plant resistance on sugarcane to the sugarcane stem borers of Diatraea spp. is normally conducted in Colombia under field conditions, where environmental variations make the study of the insect-plant relationships difficult. Additionally, several species (i.e., D. saccharalis, D. indigenella, D. tabernella, and D. busckella), whi...

Most studies on insect biology and ecology of sugarcane borers have focused on Diatraea saccharalis (Fabricius), the most widely distributed species in the Americas. Little information is available on the biology of other borer species present in Colombia, such as D. indigenella Dyar & Heinrich, D. busckella Dyar & heinrich, and D. tabernella Dyar,...

Lydella minense and Billaea claripalpis (Diptera: Tachinidae) are important parasitoids used in augmentation biological control of sugarcane stem borers, Diatraea spp. (Lepidoptera: Crambidae), the primary pests of sugarcane in Colombia. Following the recent discovery of two new Diatraea species in the Cauca River Valley (CRV), D. tabernella and D....

EIn Colombia plant breeding in sugarcane does not consider host plant resistance to insects, including the sugarcane stem borers Diatraea spp., but at the final stage of selection, known as regional trials, evaluations of sugarcane stem borers injury are made during three crop cycles and in different localities, providing information regarding resi...

The sugarcane stem borers Diatraea spp. are the most important sugarcane pests in Colombia. In the country the production of varieties does not involve selection for insect resistance, but in the final stage of selection evaluations are made on the percent of bored internodes (Infestation Intensity) and an Injury Rating is given according to the in...

Releases of the parasitoid Cotesia flavipes have been carried out since late 2014 in Colombia's Cauca River Valley to complement other biological control on sugarcane stem borers (Diatraea spp.). To confirm the identity of the species being released as well as those recovered in the field, including samples from the department of Santander in weste...

El complejo de los barrenadores plaga en caña de azúcar en el valle del río Cauca está conformado por Diatraea saccharalis, D. indigenella y recientemente por D. tabernella y D. busckella (Vargas y Gómez, 2014). Para el control de estas especies se requiere un complemento al control por moscas Tachinidae como es Cotesia flavipes. En este estudio se...

Algunas especies de hormigas son plagas, entre estas Nylanderia fulva (hormiga loca), introducida en Colombia hace aproximadamente cuarenta años, donde causa problemas ambientales y económicos en cerca de veinte cultivos y áreas asociadas. El reporte más reciente de esta especie proviene de la Vereda Holanda (Pitalito, Huila, Colombia) en cultivos...

Two genes from Streptomyces albidoflavus, one exochitinase (905-bp) and an endochitinase (1100-bp) were functionally expressed in Escherichia coli in form of a fusion protein with a maltose binding protein (MBP). The goal was to produce and test proteins that inhibit both the coffee berry borer insect Hypothenemus hampei and the coffee rust fungus...

Se comparó la riqueza y composición de especies de hormigas en la comunidad indígena Monifue-Amena (Leticia, Amazonas - Colombia) en dos unidades de vegetación: Bosque de Tierra Firme (BTF) y Várzea, durante cuatro años. Se realizaron cuatro muestreos en época seca y cuatro en lluviosa, empleando trampas Pitfall, Corner, Winkler, Zarandeo y colecta...
