Intracellular Bacteroids in the Cockroach (Periplaneta americana Linn.).
Problems involving the so-called "intracellular symbionts"2 have long troubled some cytologists and bacteriologically inclined zoologists. The solution of many of those problems, however, yet evade even the most careful investigators. Several workers in this field (Buchner, Glaser, Mlercier, Schwartz) hold to the view that the physiology and systematic position of the intracellular bacteroids c...
متن کاملodor-tracking performance in the American cockroach Periplaneta americana
Determining the location of a particular stimulus is often crucial to an animal’s survival. One way to determine the local distribution of an odor is to make simultaneous comparisons acrossmultiple sensors. If the sensors detect differences in the distribution of an odor in space, the animal can then steer toward the source. American cockroaches, Periplaneta americana, have 4 cm long antennae a...
متن کاملEvidence of poly(ADP-ribosylation) in the cockroach Periplaneta americana.
Poly(ADP-ribosylation) is a post-translational modification of nuclear proteins typical of most eukaryotic cells. This process participates in DNA replication and repair and is mainly regulated by two enzymes, poly(ADP-ribose) polymerase, which is responsible for the synthesis of polymers of ADP-ribose, and poly(ADP-ribose) glycohydrolase, which performs polymer degradation. The aim of this wor...
متن کاملSpatial learning in the restrained American cockroach Periplaneta americana.
Spatial learning abilities were tested in restrained cockroaches by observing antennal projection responses towards the positions of a learned visual cue perceived monocularly by one eye in the context of a second stimulus provided to the contralateral eye. Memory of the position of the conditioning stimulus relative to the contralateral reference stimulus was tested by altering the relative po...
متن کاملStudies of cardio-regulation in the cockroach, Periplaneta americana.
The circulation of haemolymph in insects is maintained by a system of muscular pumps and fibromuscular septa. The most important muscular pump is the dorsal vessel which collects blood from the abdominal cavity and discharges it into the head. In cockroaches the dorsal vessel is a straight tube comprising the 'heart' in the abdominal and thoracic segments and narrowing to form the aorta in the ...
