Recent research has shown that entrance guards of the stingless bee Tetragonisca angustula make less errors in distinguishing nestmates from non-nestmates than all other bee species studied to date, but how they achieve this is unknown. We performed four experiments to investigate nestmate recognition by entrance guards in T. angustula. We first investigated the effect of colony odours on acceptance. Nestmates that acquired odour from non-nestmate workers were 63% more likely to be rejected while the acceptance rate of non-nestmates treated with nestmate odour increased by only 7%. We further hypothesised that guards standing on the wax entrance tube might use the tube as an odour referent. However, our findings showed that there was no difference in the acceptance of non-nestmates by guards standing on their own colony?s entrance tube versus the non-nestmate?s entrance tube. Moreover, treatment of bees with nestmate and non-nestmate resin or wax had a negative effect on acceptance rates of up to 65%, regardless of the origin of the wax or resin. The role of resin as a source of recognition cues was further investigated by unidirectionally transferring resin stores between colonies. Acceptance rates of nestmates declined by 37% for hives that donated resin, contrasting with resin donor hives where acceptance of non-nestmates increased by 21%. Overall, our results confirm the accuracy of nestmate recognition in T. angustula and reject the hypothesis that this high level of accuracy is due to the use of the wax entrance tubes as a referent for colony odour. Our findings also suggest that odours directly acquired from resin serve no primary function as nestmate recognition cues. The lack of consistency among colonies plus the complex results of the third and fourth experiments highlight the need for further research on the role of nest materials and cuticular profiles in understanding nestmate recognition in T. angustula.

The objective of the current work is to evaluate the influence of phosphorus (P) on the accumulation of dry matter as well as the nitrogen (N) and P uptake by the umbu. The experiment was conducted under greenhouse conditions and seeds were placed in a 3-liter pot containing Yellow Latosol soil. The experimental design was entirely randomized, employing different P levels (0; 8; 16; 32 and 64 mg kg-1 of soil). The experiment was concluded 108 days post planting, and the characteristics of growth as well as the N and P uptake were evaluated. The P was found to be significant as it promoted an increase in stem diameter, which could improve grafting and establishment of the plants in the field. The least value of Total Dry Mass (TDM) was obtained when the plants were cultivated in the absence of P. Up to the dose of 32 mg of P the increase in the accumulation of Dry Mass by Absorbing Root (DMAR) was slow and gradual; however, between the doses of 32 and 64 mg of P, a substantial accumulation of dry mass in this plant region was observed. The deficiency of P significantly reduced the uptake of P and N, although it did not change the N: P ratio. Phosphorus fertilization allowed greater growth of the xylopodium, local where water and nutrients storage ocurrs; therefore, P fertilization may contribute to increased drought tolerance of this specie. The concept of P-fertilization is highly significant for the growth of the umbu. |
