In addition, when ant were teted for orientation indoor after dilacement from their outdoor foraging trail, thoe exoed to overcat condition maintained the correct trail heading but other exoed to clear kie did not. THE GEOAGNETIC FIELD AS A BACKUP CUE FOR ANTS Exeriment with naturally foraging weaver ant, Oecohylla maragdina, revealed that their ene of direction i tronger and more accurate under clear kie than under overcat kie. However, termite worker and oldier, which have oor viion at bet, rely more on nonviual cue. Indeed, an inect cometence in magnetic field orientation may be hidden if more alient cue uch a light are reent. For mot navigating inect, the rimacy of viual cue mut be taken into account in exeriment deigned to invetigate magnetic field orientation.

uch i known about how ant and bee ue viual cue uch a the un, olarized light, the moon, and landmark for atial orientation. Home Range Orientation in Social Inect The magnetic ene of inect and it adative imortance have been mot thoroughly invetigated in ocial inect uch a ant, bee, and termite that require highly develoed orientation kill to find and then communicate to their netmate the location of reource within their home range. In contrat, a geomagnetic inclination coma, a ued by ome migrating bird, ha not been demontrated for any inect. The inect alway reonded to change in the magnetic field declination, which imlie ening of magnetic olarity. AGNETIC COPASS ORIENTATION ultile directional orientation or coma orientation to artificially induced magnetic field ha been hown in everal ecie. On the other hand, it i difficult to imagine how an inect could make adative ue of ening the abolute trength of the local geomagnetic field. Both honey bee building comb in darkne and blind termite building oriented mound aear to ue magnetorecetion for aligning their tructure. agnetic coma orientation can be ueful for inect in the context of home range (toograhic) orientation and during long-ditance migration, eecially in the abence of viual coma cue.

The enory ytem that mediate magnetorecetion in inect ha not been identified definitively, though one favored hyothei i baed on the detection of magnetic field uing article of magnetite. Which of thee alternative ertain to inect ha been invetigated in only one ecie, the yellow mealworm ( Tenebrio molitor ) (Coleotera), which make ue of the olarity coma. Like a number of bird, animal either make ue of the direction in which the di angle oint ( inclination coma ) regardle of the field olarity or ene the local declination and olarity ( olarity coma ). Two alternative roertie of the local geomagnetic vector could erve thi uroe. There i evidence that a few inect ecie obtain directional information from geomagnetic field for coma orientation. 1 592 agnetic Sene c agnetic Sene John Klotz Univerity of California, Riveride Rudolf Jander Univerity of Kana, Lawrence Exerimental evidence for magnetic field enitivity ha been reorted in inect belonging to variou order, including Iotera (termite), Ditera (flie), Coleotera (beetle), Hymenotera (ant and bee), and Leidotera (moth and butterflie).
