| Popis: | Rearing pests or parasites of very small size in the absence of their living host is a challenge for behavioural, physiological and pathological studies. For feeding Varroa destructor, an ectoparasitic mite of Apis mellifera, a confinement space with a membrane separating the nutritive solution and the space was designed. The mite measures less than 2 mm and bears a perforating apparatus with a length of 15 μm. The membrane, an essential element of the chamber, has a thickness of 0.1 μm, and is made of chitosan. It closes one face of the individual confinement chamber and allows piercing and the ingestion of the nutritive solution. Factors inducing feeding can be applied on the inner walls or on the membrane. In the particular case of Varroa, the highest percentages of feeding mites are obtained by addition of host haemolymph to the nutritive solution, suggesting the kairomonal role of haemolymph in addition to its nutritional one. The membrane concept can be easily applied to several mites or other micro-pests. |
