Inventario de hymenoptera asociados a plantaciones forestales del género Eucalyptus pertenecientes a la empresa NOVOPAN del Ecuador S.A..

Abstract

The aim of this research was to carry out an inventory of insects of the Order Hymenoptera associated with forest plantations of the genus Eucalyptus belonging to NOVOPAN DEL ECUADOR S.A. The development of this study was carried out in two farms located in the cantons of "San Miguel de Urcuquí and "Ibarra" in the province of Imbabura. In order to know the entomological diversity of this order, three samplings were carried out (at different times) using the technique of yellow plates in a solution of soapy water, where 2 plates were installed for each altitudinal gradient of the company's farms (low, medium, high), the collection of samples was performed 24 hours after the traps were installed with the help of laboratory flasks and 96% alcohol, each sampling lasted 3 days; In addition, the company's interest in knowing the abundance of the parasitoid Anaphes nitens led it to carry out two samplings through the collection of 10 leaves with oothecae (pseudo parasitized) of Gonipterus sp., taking 3 trees for each altitudinal gradient. As a result, 141 individuals distributed in 15 families were recorded at Hacienda "Pisangacho" and 346 individuals distributed in 19 families at Hacienda "La Magdalena". The distribution of Anaphes nitens was recorded in the three gradients of Hacienda "Pisangacho" and only in two gradients of Hacienda "La Magdalena". In conclusion, the two Haciendas have a high diversity, it is recommended to continue with research on Hymenoptera in Ecuador and to provide a food supplement to A. nitens.
