Parasitism of Trichogramma and predation of Chrysoperla on Compsus viridivittatus eggs, a Vitis vinifera pest, under laboratory conditions
The parasitic potential of Trichogramma exiguum and Trichogramma pretiosum and the predatory effect of Chrysoperla carnea were evaluated on Compsus viridivittatus eggs, an insect pest in grape fields in Boyaca, Colombia. The T. exiguum and T. pretiosum tests used 240 eggs groups exposed to 0, 15, 30...

| description | The parasitic potential of Trichogramma exiguum and Trichogramma pretiosum and the predatory effect of Chrysoperla carnea were evaluated on Compsus viridivittatus eggs, an insect pest in grape fields in Boyaca, Colombia. The T. exiguum and T. pretiosum tests used 240 eggs groups exposed to 0, 15, 30 and 45 parasitoids densities. In the C. carnea test, a second instar larva was placed with prey densities of 80, 160 and 240 C. viridivittatus eggs. A completely randomized design was used under laboratory conditions (18±2°C and 60±5% RH). In the trials with T. exiguum and T. pretiosum, the highest percentages of parasitism were obtained with the 45 parasitoid density (69.4% and 82.5%, respectively). It was established that T. pretiosum was more effective in the parasitism of C. viridivittatus than T. exiguum, resulting in larvae emergence under 13% and parasitism over 70%. The test with C. carnea showed that the highest consumption percentage (85.8%) was obtained with the 80 C. viridivittatus egg density. There was no emergence of parasitoids from the eggs parasitized by T. exiguum and T. pretiosum, probably because of the environmental conditions and/or C. viridivittatus host intrinsic characteristics. The tested entomophagous species showed over 50% C. viridivittatus egg mortality, suggesting that they can be used in future field tests in grape vine crops in order to observe their potential in C. viridivittatus biological control programs in Boyaca. |

Se evaluaron los potenciales parasíticos de Trichogramma exiguum y Trichogramma pretiosum y del depredador Chrysoperla carnea sobre huevos del picudo Compsus viridivittatus, plaga presente en cultivos de vid en Boyacá, Colombia. En ensayos con T. exiguum y T. pretiosum, se emplearon grupos de 240 huevos del picudo expuestos a densidades de 0, 15, 30 y 45 parasitoides. En el ensayo con C. carnea se empleó una larva de segundo instar del depredador y densidades de presa de 80, 160 y 240 huevos de C. viridivittatus. Los ensayos se establecieron en condiciones de laboratorio (18±2°C y 60±5% HR) con un diseño experimental completamente al azar. En los ensayos con T. exiguum y T. pretiosum el mayor porcentaje de parasitismo se obtuvo con una densidad de 45 parasitoides (69,4 y 82,5%, respectivamente). Se estableció que T. pretiosum fue más efectivo, parasitando huevos de C. viridivittatus que T. exiguum, originando una emergencia de larvas inferior al 13% y parasitismo superior al 70%. El ensayo con C. carnea evidenció que el mayor nivel de consumo (85,8%) se obtuvo con una cantidad de presas de 80 huevos de C. viridivittatus. No se presentó emergencia de los parasitoides tanto en los huevos expuestos a T. exiguum como T. pretiosum, atribuible a las condiciones ambientales y/o características intrínsecas del huésped C. viridivittatus. Los entomófagos evaluados originaron porcentajes de mortalidad en huevos del picudo, superiores al 50%, sugiriendo su posterior evaluación en campo para establecer un posible uso en programas de control biológico de C. viridivittatus en vid en Boyacá.
