| function of secretion of mandibular gland of male in territorial behavior ofxylocopa sulcatipes (hymenoptera: anthophoridae). | males of the carpenter bee,xylocopa sulcatipes, establish and defend territories which they mark with the secretions of their mandibular glands. chemical analysis of the glandular blend revealed that it is composed of guaiacol,p-cresol, and vanillin. territorial males recognize other intruding males either by sight or by the odor emitted from their mandibular glands. they chase the intruder out of the territory immediately, but will not do so if the visitor is a female. if a female, however, is ... | 1983 | 24407763 |
| modification of potassium movement through the retina of the drone (apis mellifera male) by glial uptake. | intracellular recordings were made in photoreceptors and glial cells (outer pigment cells) of the superfused cut head of the honey-bee drone (apis mellifera male). when the [k+] in the superfusate was abruptly increased from 3.2 mm to 17.9 mm both photoreceptors and glial cells depolarized. the time course of the depolarization of the photoreceptors was slower with increasing depth from the surface. half time of depolarization was plotted against depth: this graph was compatible with the arrival ... | 1983 | 6887045 |

| synthesis of δ-lactonic pheromones ofxylocopa hirsutissima andvespa orientalis and an allomone of some ants of genuscamponotus. | simple preparations ofcis-3,6-dimethyltetrahydro-2-pyrone, vii,6-n-undecyltetrahydro-2-pyrone, xviib, and 6-n-pentyl-5,6-dihydro-2-pyrone, xvia, have been achieved. products vii and xviib, respectively, are the major constituent of the pheromonal blend of a carpenter bee (xylocopa hirsutissima) and the pheromone of the queens of the oriental hornet (vespa orientalis). the lactone xvia is a suspected defensive allomone in two species of formicine ants of the genuscamponotus. all three compounds h ... | 1983 | 24407618 |
| spider leg autotomy induced by prey venom injection: an adaptive response to "pain"? | field observations showed orb-weaving spiders (argiope spp.) to undergo leg autotomy if they are stung in a leg by venomous insect prey (phymata fasciata). the response occurs within seconds, before the venom can take lethal action by spread to the body of the spiders. autotomy is induced also by honeybee venom and wasp venom, as well as by several venom components (serotonin, histamine, phospholipase a(2), melittin) known to be responsible for the pain characteristically elicited by venom injec ... | 1983 | 16593325 |

| transfilter studies on the mechanism of epitheliomesenchymal interaction leading to chondrogenic differentiation of neural crest cells. | interaction with an epithelium is a prerequisite for avian cranial neural crest (nc) cells to differentiate into cartilage and bone (bee & thorogood, 1980). in order to investigate the causal mechanism we have selected one such interaction - that between mesencephalic nc and retinal pigmented epithelium (rpe) for further study. premigratory nc cells were grown transfilter to rpe explants of different developmental ages and on nuclepore filters of different pore size which either allowed or preve ... | 1983 | 6886609 |
| the effect of counterions on melittin aggregation. | melittin, a surface-active polypeptide from bee venom, has an overall hydrophobic n-terminus, with basic residues clustered at the c-terminus. in aqueous solution melittin exists as a mixture of monomer and tetramer, the monomer adopting a predominantly random-coil configuration, whereas the tetramer is rich in alpha-helix. the tendency of melittin to aggregate is dependent on the counter-anions present in solution, the effect being most marked with phosphate, decreasing in the order hpo4(2-) gr ... | 1983 | 6882364 |
| classical conditioning of proboscis extension in honeybees (apis mellifera). | extension of the proboscis was conditioned in restrained honeybees with odor as the conditioned stimulus (cs) and sucrose solution--delivered to the antenna (to elicit extension of the proboscis) and then to the proboscis itself--as the unconditioned stimulus (us). in a first series of experiments, acquisition was found to be very rapid, both in massed and in spaced trials; its associative basis was established by differential conditioning and by an explicitly unpaired control procedure (which p ... | 1983 | 6872507 |
| hyperreactivity to bee stings: reevaluation. | (a) a survey of beekeepers in israel did not show that they differed allergy-wise from the general population. (b) twenty-eight non-beekeeper systemic reactors to bee stings were not necessarily more allergic or more exposed to stings than the others. these systemic reactors had a spontaneous kinin system hyperreactivity and in some of them changes in the immune system and a complement defect were detected. we think that predisposition may enhance the likelihood of a systemic reaction to bee sti ... | 1983 | 6552888 |
| calculating nectar production rates: residual nectar and optimal foraging. | bumblebees, when foraging for nectar in flowers of aconitum columbianum, do not consistently drain them of reward. the amount of residual nectar varies among sites, times and species of bee. at times, residual nectar can be a significant percentage of total 24 h production strongly suggesting that, if nectar secretion rates are to be studied, flowers must have their standing crop of nectar drained by hand; assuming that a recently visited blossom is empty can lead to erroneous nectar production ... | 1983 | 28310588 |

| flower handling efficiency of bumble bees: morphological aspects of probing time. | the time required for a bumble bee to visit a flower is affected by the length of the bee's glossa and its body weight, and by the depth of the flower and the volume of nectar it contains. probing time is comprised of two components: access time and ingestion time. access time increases linearly with flower depth, but ingestion time varies with flower depth only in flowers deeper than the length of the bee's glossa, due to a decline in the rate of ingestion of nectar. probing time therefore incr ... | 1983 | 28310186 |
| community patterns of nectivorous adult parasitoids (diptera, bombyliidae) on their resources. | highly diverse assemblages of nectivorous bee flies (diptera: bombyliidae) occur at desert sites in california presenting an opportunity to investigate the ecology of this little-known group. this study compared communities of adult bee flies visiting flowers at two sites, one in the mojave desert (darwin plateau) and one in the great basin (mono basin), during periods of higher and lower resource abundance. the range of resources used by single species varied inversely with the number of specie ... | 1983 | 28310177 |
| is erythrocyte membrane phospholipid organisation abnormal in duchenne muscular dystrophy? | many of the abnormalities reported in erythrocytes from duchenne muscular dystrophy (dmd) patients, including alterations in the physical state of the membrane as determined by electron spin resonance, could arise from changes in the lipid components. although several investigators have shown there to be no compositional differences between normal and dmd erythrocytes, there still exists the hitherto unexplored possibility that the normal asymmetric organisation of the lipids may be deranged in ... | 1983 | 6839505 |
| conformational change of mastoparan from wasp venom on binding with phospholipid membrane. | the conformational change upon binding with phospholipid membrane has been studied of mastoparan from wasp venom, a tetradecapeptide causing the degranulation of mast cells. the 270-mhz 1h-nmr spectra and cd spectra indicate that the mastoparan molecule takes the alpha-helical conformation in methanol solution, but a much less ordered form in aqueous solution. on binding with phospholipid membrane, the alpha-helical conformation is formed even in aqueous medium. such a conformational change is p ... | 1983 | 6825849 |
| oxygen uptake occurs faster than sodium pumping in bee retina after a light flash. | when neurones are active there is an entry of na+, which must subsequently be pumped out, and an increase in their oxygen consumption rate (qo2). the na+ pump derives its energy from atp, splitting it into adp and pi, and it has reasonably been proposed that the changes in concentrations of atp, adp and pi lead to a stimulation of the o2 consumption by the mitochondria and hence to a restoration of the stock of atp. here we present evidence suggesting that qo2 must be controlled differently in t ... | 2013 | 6828139 |
