Avaliação do impacto ambiental da criação do parasitoide Habrobracon Hebetor (SAY, 1857) (Hymenoptera: Braconidae) e a reutilização de resíduos da criação.

Abstract

The flour moth Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae) is considered one of the main pests of stored products, highlighting that the eggs and larvae of E. kuehniella are widely used in biofactories as hosts for the multiplication of parasitoids used in biological control programs. The usual diet for breeding this insect is made up of wheat flour (97%) and brewer's yeast (3%) and at the end of breeding. residues are generated from the diet that was not completely consumed. The reuse and bioconvection of waste generated in biofactories, as well as the assessment of environmental impacts associate to their production processes are aligned with the concepts of bioeconomy. Therefore, this study aimed to verify the reuse of E. kuehniella larval diet within a new production cycle, evaluate the degradation of these residues by Hermetia illucens (Diptera: Stratiomyidae), perform a bibliometric analysis with keywords ‘frass’ and ‘Hermetia illucens” and carry out a study to evaluate the life cycle of biofactory of the parasitoid Habrobracon hebetor (Say, 1836) (Hymenoptera: Braconidae). Different mixing proportions of the standard diet with residue were prepared and the quality indicators of E. kuehniella breeding were verified, the bioconversion of residues by H. illucens was tested, the use of the VOSviewer Software made it possible to map studies of H. illucens frass, and using the SimaPro Software, an assessment of the life cycle of a biofactory was carried out. The results of reusing the diet of E. kuehniella larvae indicated the possibility of using up to 75% of dietary residues. H. illucens was responsible for reducing biofactory residue by up to 80.9%. The bibliometric evaluation on the topic “frass and H. illucens” indicated a 66.6% growth in publications between 2020 and 2023. The assessment of the life cycle of the biological agent H. hebetor demonstrated environmental advantages in relation to the use of phosphine in 15 of the 16 damage categories studied. The results indicate that applied entomology has great potential in solving environmental problems.
