Caracterización morfológica de los hiperparásitos de los enemigos naturales del caterpillar del banano

Abstract:

The characteristic morphologic of the hyperparasites of the natural enemies of the caterpillar Antichloris viridis of the banana tree one carries out in the country property Celia María during the months of April to August /09 in that was studied the biological events related with the natural control of their larval state and hiperparasitismo, for three serial generations, objectives: 1.Estudiar the fluctuation of the population of the parasitoids of larva’s and pustules of the Caterpillar in three serial generations; 2. to quantify the level of the hiperparasitismo of the natural enemies; 3. to collect the hyperparasites and to characterize them in their aspects morphology. In the plantation you monitor in situ the plague observing the emergency of adults starting from pustules collected in the sector B, with 12 hectares of banana tree. Of prompt plants he/she took the 8va leaf making two superficial courts to the two sides of the petiole, and then by means of a final cut in the center their fall takes place; it placed it to him in the floor with the back up and you proceeded to see the caterpilar population, registering larva’s for sizes and the natural control. These events were carried out in the third and quarter week of the development of larva’s. The variables measures were: Population larvary for leaf. Percentage of the natural control. Percentage of hiperparasitoides emergency. The studied generations corresponded those registered among the months of April - September /09. The classification of the hiperparasitoides one carries out using descriptions taxonomical of the superfamilia Chalcidoidea. The population laver of Antichloris viridis was moderate to low, and the natural control in correspondence with the plague was much dispersed. In this context agro ecological that characterized to the study area the natural control caused by Elachertus, Meteorus, Casinaria has more than enough larva’s and of Brachymeria in pustules was also very dispersed.
