Evaluación del método de perturbación mínima en la replicación de colonias de abejas nativas (Tetragonisca angustula).

Abstract

Native bees, especially those of the genus Tetragonisca, such as Tetragonisca angustula, also known as "angelite bees" or "stingless bees", play a fundamental role in biodiversity and agriculture. The objective was to evaluate the minimum disturbance method in the replication of native bee colonies (Tetragonisca angustula) on the hive's productivity. The project was developed in the Cucutilla municipality, Cucutillita village, El Escondido farm. The colonies were multiplied using the minimal disturbance method, subtracting the nest from the mother hives (6 hives). The multiplication was carried out by 3 types of INPA model boxes, fed with honey of the same species. The treatments evaluated were: T1 control): INPA model box with dimensions 22 cm2 externally, 12 cm2 internally, 6 cm wide, 4 cm at the base and 9 cm high on each floor or top; T2): INPA model box with dimensions 21 cm2 externally, 11 cm2 internally, 5 cm wide, 3 cm at the base and 8 cm high on each floor or top and the T3): INPA model box with a dimension 23 cm2 externally, 13 cm2 internally, 7 cm wide, 5 cm at the base and 10 cm high on each floor or rise; Each treatment had 2 repetitions, where the production and pollen production variables were evaluated. The experimental data were analyzed and compared by analysis of variance (ANOVA), using the statistical program S.A.S (Statistics Analysis System). 9.4. Honey and pollen production did not present a significant effect. The INPA model box measurements did not affect honey and pollen production by native bees (Tetragonisca angustula), but the minimal disturbance method was successful.
