Larvicidal activity and effects on post embrionary development of laboratory reared Musca domestica (Linnaeus, 1758) (Diptera: Muscidae), treated with Brevibacillus laterosporus (Laubach) spore suspensions

• Larvae of Musca domestica were killed by Brevibacillus laterosporus (strain Bon707) in a dose dependent manner.
• Strain Bon707 did not cause pupal mass variation, as such it did not inhibit feeding.
• It did not cause variation in the duration of the developmental stages of M. domestica.
• Histopathologic examination of the gut lumen revealed cellular vacuolization and cytoplasmic disorganization.

The application of a spore suspension of Brevibacillus laterosporus (Laubach) (strain Bon707), at a concentration of 1.94 × 109 CFU/mL in the diet, induced a level of 70% mortality in larvae of Musca domestica. No sublethal effects, upon feeding activity or development were recorded. However, electron microscopic examination of the digestive tract of larvae fed with B. laterosporus, revealed cellular vacuolization and cytoplasmic disorganization.
