Erratum to: Acaricidal effect and histological damage induced by Bacillus thuringiensis protein extracts on the mite Psoroptes cuniculi.

The original version of this article [1] unfortunately contained mistakes. Panel headings in Figs. 3, 4 and 5 (Figs. 1, 2 and 3 here) were included incorrectly.

Fig. 1

Photomicrograph of longitudinal sections in control (a, b), treated mites with the strain GP532 of B. thuringiensis (c, d) or with ivermectin (e, f). LU: lumen of the intestine, MP: peritrophic matrix, EC: ectoperitrophic space, MB: basement membrane, CI: intestinal content, Va: vacuole, VEM: medium ventricle, Ov: ovary. Arrows indicate alteration on the intestinal basement membrane or vacuole shaped fat deposits in ventricle, H&E- X40

Fig. 2

Representative image of the structure of the columnar cells in the mite P. cuniculi without treatment (a) or after treatment with the strain GP532 of B. thuringiensis (b) or ivermectin c, and their respective images through the relief filter (a1, b1, c1). Arrows indicate presence of dilated intercellular spaces of the columnar epithelium regarding the peritrophic matrix. Bar = 20 μm

Fig. 3

Photomicrograph of longitudinal sections in nervous system of control mites (a) or treated with the strain GP532 of B. thuringiensis (b) or ivermectin (c). Syn: Synganglion

The first column in Fig. 3 (Fig. 1) should have been labelled ‘Control’ the third column ‘Ivermectin’. The first row should be labelled ‘Intestine’ the second ‘Ventricle’.

The first row in Fig. 4 (Fig. 2) should have been labelled ‘Control’ the second row should be "GP-132 BT", and the third row ‘Ivermectin’. Panel ‘b2’ should have been labelled ‘b1’.

The first column in Fig. 5 (Fig. 3) should have been labelled ‘Control’, the third column ‘Ivermectin’.

The figures are included correctly below and have been updated in the original publication.
