(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2015)
A new species of soft scale insect from Colombia and Venezuela, Toumeyella coffeae Kondo sp. nov., is described and illustrated based on the adult female. A taxonomic key to the genera of scale insects of the Toumeyella-group and a list of 49 soft scale insect (Coccidae) species recorded from Coffea spp. worldwide are provided.
Evaluation of three hydrolyzed proteins for capturing adults of the yellow pitaya flowerbud fly, Dasiops saltans Townsend (Diptera: Lonchaeidae)Evaluación de tres proteínas hidrolizadas para la captura de adultos de la mosca del botón floral de la pitaya amarilla, Dasiops saltans Townsend (Diptera: Lonchaeidae)

Three baits for trapping the pitaya flower-bud fly, Dasiops saltans Townsend (Diptera: Lonchaeidae) in yellow pitaya, Selenicereus megalanthus (Cactaceae) orchards were evaluated. The tested baits were hydrolyzed soy protein (without monosodium glutamate), hydrolyzed soy protein with monosodium glutamate (commercial soy sauce), and hydrolyzed corn protein (without monosodium glutamate), which were put into McPhail traps ...
Applications of entomopathogenic bacteria Bacillus thuringiensis to control phytopathogensAplicaciones de la bacteria entomopatógena Bacillus thuringiensis en el control de fitopatógenos
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2011)
The overuse of chemical pesticides causes esistance in phytopathogens and negative influences on the environment and human health; therefore, the implementation of control strategies of beneficial microorganisms such as Trichoderma spp., Bacillus spp., Pseudomonas spp., and other promising agents is compelling. Bacillus thuringiensis is the most widely used biological insecticide in the world; it controls various insects ...

Symbiotic asociation of arbuscular mycorrhizal fungi and the root system of cocoa (Theobroma cacao L.) seedlings: effect of formononetin and phosphorus availability at soil levelAsociación simbiótica entre hongos micorrízicos arbusculares y el sistema radicular de plántulas de cacao (Theobroma cacao L.): efecto de la formononetina y la disponibilidad de fósforo en el suelo.
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2010)
The symbiosis established between cacao plants and arbuscular mycorrhizal fungi (AMF) adds nutritional and competitive benefits for the plant, especially in conditions with a low availability of nutrients. We evaluated three levels of phosphorus (5, 20 and 40 ppm) and the presence or absence of isoflavone formononetin. A Phosphorus level of 14 ppm, without isoflavone or inoculation was the control. All treatments were ...
