Pollinators community structure and multivariant analysis of tomato’s quality fruit Lycopersicon esculentum Mill (Solanaceae) in a crop located in Caldas – Colombia.

Abstract

We determined the community pollinators and analyzed tomato’s quality fruit Lycopersicon esculentum Mill cultivated in Viterbo-Caldas Colombia’s municipality. We sampled in a flowering semi greenhouse doing randomly for highest foraging areas around. Were recorded plant-flower visitors each inspected plant and its control, obtaining abundance and genera values from those by counting per hour ranges. We used a Principal Component Analysis to analyze ecological and economical variables of fruit quality. We used a T, diversity. And genera accumulation curve was graphed. To analyze the sample representativeness we obtained the Chao1, ACE, ICE, Singletons y Doubletons estimators. Pollination percentage in crop 57.7%. We taxonomically identified four genera of pollinating bees: Apis , Melipona, Agapostemon, and Euglossa. Highest foraging activity ranging from 8 to10 am was found. Weight vs polar diameter was close to Agapostemon (R=1, p=0.0026, CP1=78.3% y CP2=21.7%). T-test showed significantly differences (p=0.0035) between cross and self pollination. Diversity indices (E = 0.90460) suggested a low pollinators’ richness, dominance and diversity (DMg=1.13677; Dsp=0.25275; H’=1.25404). The sampling was representativeness as Chao 1 100% and ACE 90% estimated. Among 50% of the crop is not exploited productively. cross pollination makes by Agapostemon becomes fruits’ weight and polar diameter improve.
