Successfully inserting a biocontrol agent (BCA) in the integrated management of mango fruit decay can be affected by several factors, including BCA inoculum density and the timing of its application. This study focused on improving biocontrol efficacy by adjusting doses of a BCA formulation and the timing for the substitution of synthetic fungicides sprays. Technical grade formulations containing increasing doses (104 ? 108) of the yeast strains Saccharomyces sp. ESA45, S. boulardii ESA46, Saccharomyces sp. ESA47, and Pichia kudriavzeviii CMIAT171 were applied to mango fruits, followed by the inoculation of Lasiodiplodia theobromae and Neofusicoccum parvum in artificial wounds. Non-linear regression analysis of increasing doses of the BCAs against severity data and curve slopes comparison showed a significant difference in control efficiency among yeast strains. A log-linear regression model showed that ESA45 and CMIAT171 exhibited lower doses to achieve 90% control. Two field experiments were conducted in commercial mango orchards cultivated with the cultivars ?Kent? and ?Palmer?. Starting the substitution of fungicides by BCA in fruit onset and when fruits achieved egg size resulted in lower fruit rot incidence and severity during cold storage and shelf life. The complete substitution of fungicides during fruit development did not show consistent performance. Similarly, applying BCA formulation only at the end of fruit development did not hinder the establishment of quiescent infections.

A common technique used to control phorid fly infestations on stingless bee?s nests is the use of traps with commercial vinegars, especially the red wine vinegar, which is stated to be more efficient than the white wine vinegar. However, the claims on its greater efficacy are only circumstantial, not based on experiments. Thus, the aim of this work was to test the efficacy of traps composed of red wine or white wine commercial vinegars on the attractiveness of adult Pseudohypocera kerteszi Enderlein (Diptera Phoridae) females that infested colonies of Melipona fasciculata Smith, and Melipona seminigra Friese. The comparisons were made by placing one trap of red wine vinegar and other of white wine vinegar in infested colonies of the studied species for a week to check for possible differences in their attractiveness on phorids. We also tested the possibility that traps could attract phorid flies from outside the nests, thus potentially increasing an infestation. This was tested by placing traps of red wine vinegar in empty hives in the meliponary, thus eliminating bee?s odours and food stores as factors that could attract phorid flies. There was no difference on the attractiveness of traps composed of red wine or white wine vinegars (Wilcoxon matched-pairs test), and traps did not any attract phorid flies from the outside to the interior of hives. Thus, the red wine and white wine vinegars can be equally used to capture phorid flies that invade nests of stingless bees, and they do not attract flies from outside the nests, thus not increasing infestations. The other objective of this work was to correlate the body size, particularly the maximum head width of the captured phorids and their abundance, with the monthly rainfall levels during the experimental period. We noticed an increase of abundance of phorid flies on the rainy periods, but there was no correlation with body size, which we suggest to be a consequence of the weakening of bee colonies that normally occur during the rainy season, which ease the invasion of them by phorid flies from the environment.
