This study developed a bioinsecticide formulation based on Bacillus th
uringiensis serovariety aizawai (GM-10 strain) and extracts of ''guish
e'' (a subproduct of the Agave lecheguilla processing) for the control
of Spodoptera frugiperda Smith. We analyzed crude, pregelatinized and
nixtamalinized corn flour as encapsulating material. The latter was b
est because it polymerized in the cold and formed an adequate matrix n
et. Of the protective agents tried against solar radiation, Malachite
Green, Congo Red and charcoal, the first was the best in laboratory tr
ials. The particulated formulation exhibited good characteristics for
use.
