摘要: Two types of cuticular strain detectors, the campaniform sensilla on haltere blowfly,Calliphora vicina, and slit tibia spider,Cupiennius salei, were investigated. In a transepithelial voltage (43.6±10.7 mV), which depends an intact metabolism, occurs. spider no exists. The occurrence lack is paralleled with differences in ionic composition receptor lymph two arthropod sensilla. We used double-barrelled ion-selective microelectrodes to measure potassium calcium content respect hemolymph. concentration (121±15 mM) five times larger than that wing hemolymph (25±7 nine (13±3 mM). These are statistically significant. (0.8±0.5 does not differ significantly from (1.2±0.7 significant difference occurs between (9.5 mM±5.5 (8±3 (1.6±0.9mM) 3 higher (0.6±0.3 This
