  • Title: Chemosterilization of Dermacentor variabilis Say (Acari: Ixodidae). I. Effects of metepa on the cytology and fertility of males treated as unfed adults.
    Author: Osburn RL, Oliver JH.
    Journal: J Parasitol; 1978 Aug; 64(4):719-26. PubMed ID: 682072.
    Abstract:
    The effects of metepa on the cytology and fertility of male Dermacentor variabilis treated as unfed adults are determined. Evidence of cellular damage is found in testicular areas where actively dividing cells and some enlarging spermatocytes are found. The amount of cellular damage correlates positively to the concentration of the chemosterilant and results in decreases numbers of spermatids. In crosses of treated males to untreated females, resulting egg masses hatch normally; however, the percentage of females producing egg masses that hatch is reduced.
