A mosquitocidal soil isolate of Bacillus thuringiensis serovar fukuokaensis (H3ade) produced spherical parasporal inclusions measuring 0.6–0.7 µm in diameter. Inclusion matrix was homogeneous substance surrounded by a thick, highly electron‐dense envelope 30–50 nm in thickness. The envelopes were associated with both intracellular and extracellular inclusions. Densely woven network was the inner structure of the envelope. Often, inclusions had round‐shaped, enveloped small protrusions on the surface. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
