Abstract :

The enzyme spectrum of an ectoparasitic mite of the honeybee, Varroa destructor (Anderson and Trueman) was studied using a semi-quantitative method, especially designed for complex samples which have not been purified. Exopeptidases and phosphatases are shown present. A chitinase and enzymes able to transform beta carbohydrates are also present with a large range in the intensity of the reaction. The role of the chitinase can be related to the supply of nutritional needs or/and the piercing and sucking behaviour of the adult parasite. Chitinase activity could be one factor influencing the balance between the parasite and its host.
