| ethological studies in the ant tetramorium caespitum mayr. ii. interspecific relationships. | the structure of relationships between the neighboring species of ants is characterized by great variability. what happens when particular individuals meet - depends upon considerable differences between individual behaviors of ants and a number of variable factors determining the actual emotional state of the workers. from these factors, it is the general structure of forces between the nests that changes slowest, and may be responsible for reaching temporary stabilization of the interspecific ... | 1975 | 1163309 |
| ethological studies in the ant tetramorium caespitum mayr. i. foraging and building behavior. | carrying heavy objects is a common element in the foraging and building behavior of ants. the initial stages of this behavior, i.e., lifting and moving in t. caespitum displayed as stereotyped patterns of movement. these patterns do not improve as the ants become older and more experienced, which suggest their congenital nature. growing experience of ants is manifested in the later stages of the transportation of heavy objects, and especially in entering the correct opening of the nest with the ... | 1975 | 1163308 |
| the imported fire ant: dimensions of the urban problem. | although the imported fire ant is a known rural problem, the problem it may pose to urban dwellers has not been documented. a telephone survey of 240 households selected by a probability sample of an upper middle class suburb of new orleans was carried out to ascertain the experiences of residents with fire ants from june to august 1973. overall, ant stings were reported for 29% of the study population, with sting rates of 55% among children under 10 years old. among those stung, at least minima ... | 1975 | 1162427 |

| polyzonimine: a novel terpenoid insect repellent produced by a milliped. | a nitrogen-containing terpene 6,6-dimethyl-2-azaspiro[4.4]non-1-ene (polyzonimine) was isolated from the defensive secretion of the milliped polyzonium rosalbum. polyzonimine, which is repellent to such natural enemies of the milliped as ants, acts as a topical irritant to insects (10-4 m induces scratching in cockroaches). its structure was confirmed by a five-step synthesis starting from 2,2-dimethyl-7-oxabicyclo[4.1.0]heptane. | 1975 | 1124395 |
| cyclopentyl ketones: identification and function in azteca ants. | the anal gland secretions of dolichoderine ants in the genus azteca are fortified with cyclopentyl ketones. since these compounds, 2-methylcyclopentanone, cis-1-acetyl-2-methylcyclopentane, and 2-acetyl-3-methylcyclopentene, release sustained alarm behavior in ant workers, they constitute a new chemical class of insect pheromones. the ketones probably also function as defensive compounds and thus are part of the ants' alarm-defense system. | 1975 | 1111099 |
| haploidploidy and the evolution of the social insect. | halminton (1) was apparently the first to appreciate that the synthesis of mendelian genetics with darwin's theory of natural selection had profound implications for social theory. in particular, insofar as almost all social behavior is either selfish or altruistic (or has such effects), genetical reasoning suggests that an individual's social behavior should be adjusted to his or her degree of relatedness, r, to all individuals affected by the behavior. we call this theory kinship theory. the s ... | 1976 | 1108197 |

| [evaluation of mirex for the control of pharaoh's ants]. | the paper analyses the mode of action of the organic chlorine compound mirex in laboratory colonies of the pharaoh's ant monomorium pharaonis under the special view of practical use in control measures in comparison with the related insecticide chlordecone (kepone). similar to chlordecone the queens are very susceptible towards the action of mirex. according to the regression lines of the mortality the best concentrations for practical control measures are in the range of 0.1 to 1%, respectively ... | 1976 | 1008292 |
| the foraging behavior of the ant myrmica laevinodis nyl. | the foraging territory is not divided among particular foragers, at least in the young, small families of m. laevinodis. the same individuals may be observed repeatedly only at the aphides over a period of several days, which may be explained by a transient memorizing of the source of attractive food. along with the faculty of these ants to inform their nestmates of the food source, a certain continuity in care of the aphides is ensured. various forms of behavior among particular foragers coming ... | 1976 | 1007976 |

| regional distribution of three ultrastructural retinula types in the retina of cataglyphis bicolor fabr. (formicidae, hymenoptera). | the retina of cataglyphis bicolor was investigated by electron microscopy. three types of structurally distinct retinulae were found and mapped throughout the compound eye: type i is composed of four unpigmented thin cells, four larger pigmented cells as well as a basal ninth cell. its rhabdom possesses a round cross section and four microvilli directions. this type occupies most of the dorsal two-thirds of the retina. type ii consists of two thin cells, two intermediate cells and four large cel ... | 1976 | 954049 |
| imported fire ant hypersensitivity. studies of human reactions to fire ant venom. | it is now apparent that venom and venom components of the hymenoptera superfamilies of apida (honeybee) and vespida (wasps, yellow jackets, and hornets) are becoming increasingly important in the diagnosis and treatment of hypersensitivity reactions. stings from fire ants (superfamily formicidae, family myrmicinae) have also been recognized as causes of systemic reactions in man. fire ant venom is unique in its composition, consisting mainly of alkaloids in aqueous suspension with only trace amo ... | 1976 | 947974 |

| ants and bees: whole body extracts vs venom. | ants, bees, and other stinging hymenoptera can induce serious anaphylactic reactions in susceptible individuals. certainly, hymenoptera venom contains potent antigens that have been useful in testing and treating hymenoptera-sensitive patients who fail to acquire protection from whole body extract therapy. however, before whole body extracts are forever abandoned, their antigen content and stability should be re-examined by means of modern immunologic methods. | 1977 | 872621 |
| weaver ants: social establishment and maintenance of territory. | workers of the african weaver ant oecophylla longinoda recruit nestmates to previously unoccupied space by means of odor trails laid from the rectal gland, a hitherto unrecognized musculated organ located at the rear of the rectal sac. when enemy ants and other intruders are encountered on the territory, the oecophylla assemble nestmates into small resting clusters by dispensing an attractant-arrestant pheromone from the sternal gland, a second newly discovered organ located on the last abdomina ... | 1977 | 841318 |
| sexual calling behavior in primitive ants. | the wingless virgin females of the ponerine ant rhytidoponera metallica attract males by the release of a pheromone from the tergal gland, a hitherto unrecognized exocrine gland located between the last two abdominal segments. this is the first evidence for sexual chemical communication in the large and primitive subfamily ponerinae. | 1977 | 836590 |
| [role of stimuli coming from the brood on the behavioral carrying of nymphs by workers of tapinoma erraticum (formicidae dolichoderinae)]. | in a stress situation workers of the ant tapinoma erraticum carry the brood from one nesting place to another. this carrying activity is exhibited as soon as the animal is born. it gets more precise and steadier through stimulations that originate in the brood (odour or manipulation). | 1976 | 821632 |
| insect and mammalian pheromones. | novel organic chemicals, as well as many simple molecules, are used by insects as defensive materials. social insects (e.g., ants and bees) utilize alarm pheromones consisting of terpenes and other smaller organic compounds. moths and butterflies, as well as a few beetles, have been studied extensively for their sex attractants. since the initial structure proofs of civetone and muscone by ruzicka in 1926, little mammalian pheromone research has been published. recently, deer, antelope, hyena, s ... | 1976 | 818456 |

| evaluation of functional degeneration of the amazon-ant polyergus rufescens latr. under an influence of socially parasitic way of life. | in certain, infrequently occurring, favorable circumstances the ants p. rufescens can display patterns of behavior which seem to be disappearing as a result of their parasitic way of life: the ability to food themselves, independently though ineffectively, elements of the offspring-protection behavior, transporting of nestmates, escape reaction. similar events reinforce the infrequently used, latent reflexes, preventing their complete extinction. it is supposed that the characteristic in convent ... | 1978 | 749552 |
| problem of behavioral plasticity in slave-making amazon-ant polyergus rufescens latr. and in its slave-ants formica fusca l. and formica cinerea mayr. | changes in the natural behavior, expressing adaptation to cohabitation in a community, were observed in the slave-making ants p. rufescens and the slave-species f. fusca and f. cinerea. after a few raids, the initially undirected arousal evoked in the slaves by the amazons' raids, begins to acquire attributes appropriate to the situation, but completely different in both studied slave-species. f. cinerea picks up the pupae abandoned on the nest by the slave-making ants and eventually begins to w ... | 1978 | 749551 |
| [ovine dicrocoeliasis: incidence of climatic factors and share in the setting of a forecasting method (author's transl)]. | study of annual activity cycle of ants parasited with dicrocoelium lanceolatum. effect of some climatic factors (temperature, rainfall) on seasonal variations of the number of clinching parasited ants. a close analysis of the data displays a double correlation: the increase of the number of clinching ants indirectly brought about by precipitations and this with some delay; a strong decrease by high temperatures in the height of summer. setting of a calendar including the different stages of the ... | 1978 | 727642 |
| biosynthesis of formic acid by the poison glands of formicine ants. | the biosynthesis of formic acid in the poison glands of formicine ants is closely related to the c-1 metabolism of the glandular cells. experiments utilizing radiolabeled amino acids revealed that serine is a major precursor, contributing both its alpha and beta carbons to formic acids. 5,10[14c]methylene h4folate and 5,10[14c]methenyl h4folate also serve as precursors of formic acid in the poison gland, suggesting that they are intermediates in the pathway. furthermore, these h4folate derivates ... | 1978 | 718985 |

| light propagation in twisted anisotropic media: application to photoreceptors. | the propagation of light through a slowly twisting anisotropic medium is described by a coupled-mode theory; expressions are derived for the electric field for the case of a birefringent dichroic medium with a constant rate of twist. the method provides a simple and intuitive means for determing the effect of twisting on the linear birefringence and dichroic absorption of the medium, particularly when the light is initially linearly polarized. the theory is well suited to the analysis of light a ... | 1978 | 660317 |

| electron microscopic study of light muscle degeneration in queens of atta sexdens (hymenoptera: formicidae. | the reabsorption of the flight muscles of a. sexdens queens was studied just after the autotomy of the wings, and 1,10,15,25 and 45 days thereafter. the muscle cells degenerate slowly, the first alterations taking place in the mitochondria and sarcoplasm. signs of degeneration appear in the myofibrils after only 10 days and alterations increase with time. after 45 days the myofibrils have completely disintegrated. | 1979 | 533651 |
| esterase variation at three loci in meat ants. | the meat ant (iridomyrmex purpureus) occurs in a number of color forms, with uncertain taxonomic status. gel electrophresis of meat ant extracts, followed by nonspecific esterase staining, reveals several zones of activity. allelic variation at three loci is proposed to account for variation in some of these zones. two of the loci (es-1, es-2) appear to have recessive null alleles, whose frequencies have been estimated by the method of maximum likelihood. geographic variation in allele frequency ... | 1979 | 469224 |

| colony-specific territorial pheromone in the african weaver ant oecophylla longinoda (latreille). | major workers of oecophylla longinoda mark their territories with persistent pheromones that are distinguishable to the ants at the colony level. workers detecting the deposits of an alien colony respond with increased amounts of aversive and aggressive behavior, and they later recruit nestmates to the area at a higher rate. colonies entering a field impregnated with their own scent also gain an initial advantage in warfare with other colonies. the pheromones are located at least in part in drop ... | 1977 | 266729 |

| [oxygen consumption of hibernating worker ants dolichoderus quadripunctatus as a function of temperature and level of population]. | the oxygen consumption of "hibernating" ants shows a grouping effect translated by a significant decrease in the level of oxygen consumption as a function of grouping effect. the general relation between oxygen consumption and the living body mass is the same, if the living material belongs to a single animal, or a social community of ants. | 1978 | 95901 |
| kepone--hazard evaluation. | kepone is a persistent chlorinated hydrocarbon pesticide which is no longer manufactured in the u.s.a., its uses having been cancelled on april 11, 1977; previous food uses included control of the banana root borer, and non-food uses included control of tobacco wireworm, ants, and cockroaches. an adduct of kepone, kelevan, is now distributed by spiess and sohn, chemische fabrik, germany, with an as yet unknown manufacturer, for control of the colorado potato beetle in eastern europe and ireland, ... | 1978 | 74851 |
| harvester ant sensitivity: in vitro and in vivo studies using whole body extracts and venom. | harvester ant stings by pogonomyrmex maricopa (pm) or pogonomyrmex rugosus (pr) resulted in serious reactions in 8 patients, 4 with generalized reactions and 1 with large local reactions. exposure to one species in the genus pogonomyrmex (p) appeared to cross-sensitize ant-sensitive patients to other species in the same genus as evidenced by skin testing and leukocyte histamine release, but these patients were less sensitive to extracts from other stinging hymenoptera, including bee, wasp, yello ... | 1977 | 64481 |
| application of bathurin and borax in the biological control of monomorium pharaonis in housing estates. | of two apartment houses infested with ants of the species monomorium pharaonis, one was treated with a biological, the other with a chemical substance. in the first case we used bathurin in combination with borax at a concentration of 1.3% for both substances. in the first week, borax was added to the bait (minced beef), within the next three weeks, the bait was mixed with bathurin. the procedure was repeated 5 times. after this period, we achieved complete control of the ants on the infested pr ... | 1976 | 62524 |
| [anatomic and histologic studies of a triatominae subfamily (heteroptera, reduviidae). triatoma infestans' brain and its nerves]. | to give a concrete aspect of structure, topography and function of the different nervous systems of the triatominae, we begin this study with a description of the senso-motor system. as the first part we choose the study of the brain and its nerves. the external form of the brain is conditioned by the anatomy and morphology of the head. the brain is situated in the posterior part of the head beneath and behind the ocelli. it is characterized by the reduction of its longitudinal extension and, by ... | 1976 | 45709 |
| arms races between and within species. | an adaptation in one lineage (e.g. predators) may change the selection pressure on another lineage (e.g. prey), giving rise to a counter-adaptation. if this occurs reciprocally, an unstable runaway escalation or 'arms race' may result. we discuss various factors which might give one side an advantage in an arms race. for example, a lineage under strong selection may out-evolve a weakly selected one (' the life-dinner principle'). we then classify arms races in two independent ways. they may be s ... | 1979 | 42057 |
| a contribution to the biology of dicrocoelium hospes looss, 1907 (trematoda, dicrocoeliidae). | in this study, carried out in the ivory coast, dicrocoelium hospes looss, 1907 was shown for the first time to be a parasite of cattle and it was also detected in sheep by the presence of ova in the faeces. up to 50% of the sheep in some flocks were found to shed eggs. the adults, sporocysts, "slime balls" and cercariae of d. hospes are described and compared to the respective stages of d. dendriticum. this comparison shows that essential morphological structures are very similar, especially the ... | 1978 | 28656 |
