[Solenophagy and telmophagy: biting mechanisms among various hematophagous insects].

Blood-sucking insects do not all take blood from the host in the same way. Mechanisms are different according to capillary feeding or pool feeding and this explains the differences between clinical reactions. A better knowledge of the insect biology is helpful for an aetiological diagnosis. So, in the case of an allergic reaction, procedures of complementary investigations will be optimised.
