| fire ant envenomation in children. | fire ants (solenopsis richteri and solenopsis invicta) have received scant attention from individuals other than agriculturists, entomologists, and victims of the bite and sting. since their original importation into mobile, alabama, these small, seemingly benign, creatures have slowly migrated throughout most of the southern united states. not unexpectedly, physicians working in the southern portions of the united states have been confronted with increasingly large numbers of patients, particul ... | 1984 | 6201811 |
| diagnosis of polistes wasp hypersensitivity. | patients referred from the houston, texas, metropolitan area were evaluated for allergic reactions to insect stings. forty-eight persons reported at least one systemic reaction caused by a polistes paper-nest wasp sting. honey bees, imported fire ants, and other types of hymenoptera were identified in that order by 19 other subjects with systemic allergic reactions. life-threatening airway obstruction and/or hypotension were noted by most of our patients. wasp venom skin testing was positive in ... | 1983 | 6194197 |
| mechanism of action of fire ant (solenopsis) venoms. i. lytic release of histamine from mast cells. | the mechanism of histamine release from rat mast cells by whole venom from solenopsis geminata and s. invicta or by 2-methyl-6-undecylpiperidine hcl (c11) was investigated. histamine release stimulated by one or more of these agents (1) occurred in normal and metabolically inactivated cells, (2) had a biphasic time course in normal and inactivated cells, (3) was temperature dependent and did not occur at 0 degrees c, (4) was accompanied by concomitant cytoplasmic enzyme release, (5) was accompli ... | 1982 | 6184853 |
| bites and stings of uncommon arthropods. 2. reduviids, fire ants, puss caterpillars, and scorpions. | arthropod bites and stings may cause intense pain, sometimes out of proportion to the size of the lesion. severe reactions may arise from prior exposure and buildup of antibodies. diagnosis often can be made from the clinical presentation if the physician is familiar with the effects of the uncommon bites and stings. some uncommon bites, such as those of reduviids, can be treated symptomatically, but others, such as those of poisonous scorpions, call for antivenin therapy. | 1981 | 6114485 |

| defensive use of a "fecal shield" by a beetle larva. | the larva of cassida rubiginosa carries a tight packet of cast skins and feces on a fork held over its back. the packet is a maneuverable shield used by the larva to protect itself against attack. it is highly effective in blocking the bite of ants. | 1967 | 6058687 |
| alkaline phosphatase and leucine aminopeptidase association in plasma of the chicken. | two electrophoretic vari ants of leucine aminopeptidase show direct association with two genetically controlled forms of alkaline phosphatase. treatment of plasma with neuraminidase converted the faster-migrating form of both enzymes to slower-moving forms, but plasmas with slowermigrating forms were unaffected by this treatment. the two forms of the enzymes may be due to the presence or absence of a single gene controlling the attachment of sialic acid to the enzyme molecules. | 1967 | 6024189 |

| homing in the ant cataglyphis bicolor. | cataglyphis bicolor, an ant widely distributed in north africa and the near east, orient to the sun as well as to visual patterns of the environment. these two mechanisms can be separated. foraging ants (hunters) orient to terrestrial cues as long as possible, and only after these have become ineffective do they switch over to the menotactical sun orientation. in the digging individuals, however, the visual knowledge of locality is significantly inferior to that of the hunters. diggers vary cons ... | 1969 | 5774195 |

| 2,5-dichlorophenol (from ingested herbicide?) in defensive secretion of grasshopper. | the defensive froth emitted by the grasshopper romalea microptera contains several odorous compounds (phenols, terpenes, benzoquinone), including a chlorinated aromatic compound, 2,5-dichlorophenol. this compound, which is repellent to ants and therefore defensively useful to the grasshopper, probably stems from herbicide or herbicide derivative ingested by the insect with its diet. although there is precedent for the defensive employ by one species of chemical agents produced by another, no ins ... | 1971 | 5548709 |
| chemical communication and "propaganda" in slave-maker ants. | slave-maker ants of the formica sanguinea group direct their raids by means of odor trails. artificial trails made from whole-body extracts and extracts of dufour's glands and hindguts can be used to guide columns of workers to selected target colonies and to initiate raids. in workers of f. pergandei and f. subintegra, members of the f. sanguinea group, the dufour's glands are hypertrophied and contain large quantities of three acetates (decyl, dodecyl, and tetradecyl), which are discharged at ... | 1971 | 5548706 |

| the biochemical basis of the fungus-attine ant symbiosis. | the natural history of the fungus-growing ants provides a spectacular example of a symbiotic association of two very different types of organisms. an anthropomorphic description is difficult to resist. the ants are efficient and industrious farmers. their single crop is a fungus, grown on a substrate of leaves in carefully fertilized, welltended gardens. virtually every facet of the ants' behavior and life cycle has been shaped by their association with the fungus they culture. a characteristic ... | 1970 | 5447529 |
| chemical defense of brood by a social wasp. | ants are a constant threat to the nests of tropical social wasps. adults of the neotropical social wasp mischocyttarus drewseni apply a secretion to the nest stem which is repellent to ants foraging for food by scouting and recruiting, and effectively keeps them from gaining access to the nest and discovering the brood. | 1970 | 5445937 |

| ethological studies on polycalic colonies of the ants formica exsecta nyl. | the members of a polycalic colony of formica exsecta freely walk over its various nests, while performing social functions. it seems that the external service in the species ceases to belong strictly to one nest and forms a supra-nest attachment. the probability of this relation is more credible in the light of the results of this research which disclosed a tendency to local migrations. for, both these ethological peculiarities require an inhibition of the attachment to the restricted habitat, w ... | 1973 | 4747691 |
