POLARIZED LIGHT AND BODY TEMPERATURE LEVEL AS ORIENTATION FACTORS IN THE LIGHT REACTIONS OF SOME HYMENOPTEROUS AND LEPIDOPTEROUS LARVAE

摘要: Larvae of the diprionid sawfly, Neodiprion banksianae Roh., lasiocampid, Malacosoma disstria Hbn., and tortricid, Choristoneura fumiferana (Clem.), were used to demonstrate effects heat plane-polarized light upon photic orientation immature insects. Photic was shown be primarily a result internal temperature level. When larvae heated sufficiently, they reversed sign their orientation. three species sensitive variations in plane polarization, polarization pattern sky varying degrees orientated with reference when one available. photonegative appeared orientate position sun, but rotation axis "Polaroid" screen through 90° could change direction travel by this amount. On other hand, l...
