Abstract: Aganaspis pelleranoi (Brèthes, 1924) (Hymenoptera: Figitidae) is a koinobiont endoparasitoid of larvae of species of the genus Anastrepha and of Ceratitis capitata. It is a candidate for use as a biological control agent, as under Þeld conditions, it may reach a parasitism rate of 62%. The objective of this study was to determine the effect of different constant temperatures on biological parameters of A. pelleranoi when parasitizing the larva of Anastrepha fraterculus (Wiedemann, 1830) (Diptera: Tephritidae), as well as to determine its thermal requirements. The study was conducted in environmental chambers at 18, 20, 22, 25, 28, and 30 +- 1.C; 70 +- 10% relative humidity; and a 12-h photophase. Females maintained at 18 and 20.C produced more progeny than females at other temperatures tested. The longevity of males and females was inversely proportional to temperature, ranging from 49.1 to 3.73 d for females and from 32.1 to 3.8 d for males at temperatures of 18-30.C, respectively. The duration of the biological cycle (egg-to-adult) was inßuenced by temperature, and ranged from 69.1 d at 18.C to 30 d at 25.C. No preimaginal development of A. pelleranoi occurred at 28 and 30.C. The relationship between temperature and the demographic parameters of A. pelleranoi showed a linear effect over the temperature range of 18-25.C. The lower temperature threshold and thermal constant were 11.69.C and 391.70 degree days, respectively. |

The presence of inhibitors is still an economic bottleneck that needs to be resolved in order to make the biorefineries feasible, requiring the development of technologies capable of improving their competitiveness in the biofuel marketplace. Soluble and insoluble lignin can impair the enzymatic hydrolysis process by inhibition, deactivation, and unproductive adsorption of enzymes. Washing the pretreated biomass or using lignin-blocking additives during saccharification could mitigate these negative effects in future biorefineries. Here, an investigation was performed of the combined mitigation processes, in terms of their technical and economic feasibility in an integrated first and second generation (1G2G) sugarcane biorefinery. Evaluation was made of the impacts of biomass washing and soybean protein addition, separately or in combination, on glucose yields for enzymatic hydrolysis in the presence of high (liquor) and low (buffer) concentrations of soluble inhibitors/deactivators. Combining washing and soybean protein addition provided the highest glucose yields, with an increase of up to 50%. The effect of the mitigation processes could be explained by a combination of catalytic mechanisms acting on both soluble and insoluble lignin. In an industrial context, biomass washing (90 C, 15% (w/w) solids, 3 steps) followed by soybean protein addition (12% (w/v) solids) provided a cost-competitive methodology for bioethanol production, with an estimated net present value of US$ 9.16 107 , optimizing hydrolysis process in the 1G2G sugarcane biorefinery.
