Pretreatment Processes<\/strong><\/h4>\n\n\n\n<ul>\n<li><strong>Physical Treatment<\/strong>: Crush to particle size &lt;3 cm to break fiber structure (enhances larval feeding efficiency).<\/li>\n\n\n\n<li><strong>Biological Treatment<\/strong>: Ferment with EM\u83cc (effective microorganisms) or <em>Bacillus subtilis<\/em> for 24\u201348 hours (pH 6.5\u20137.5).<\/li>\n\n\n\n<li><strong>Moisture Adjustment<\/strong>: Mix with rice husks or sawdust to achieve 60%\u201370% moisture (holds shape when squeezed, crumbles when released).<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>III.
