Distortion of the spermathecae of phytoseiid mites (Acari: Phytoseiidae) in slide preparation.
The shape and dimensions of the spermathecae are taxonomically important characteristics in phytoseiid mites. In experiments with Neoseiulus californicus (McGregor) and Typhlodromus pyri Scheuten, the shape of the cervix of the spermatheca changed considerably and its diameter was increased by 42-49% when mites were flattened, compared to being mounted with 140 microm spacers underneath the coverslips. Dimensions of the dorsal shield were also affected by flattening. increasing by 3-5%.
