| the tribe anisoscelini (hemiptera: heteroptera, coreidae) in argentina. | eight genera and 21 species of the tribe anisoscelini (coreidae, coreinae) are recorded in argentina: anisoscelis foliaceus (fabricius); coribergia declivicollis (berg); dalmatomammurius vandoesburgi (brailovsky); holymenia hystrio (fabricius); leptoglossus chilensis (spinola); l. cinctus (herrich-schaeffer); l. concolor walker; l. crassicornis (dallas); l. dentatus berg; l. fasciatus (westwood); l. gonagra (fabricius); l. impictus (stål); l. ingens (mayr); l. neovexillatus allen; l. quadricolli ... | 2015 | 26624414 |
| the male-produced sex pheromone of the true bug, phthia picta, is an unusual hydrocarbon. | phthia picta is part of a complex of true bugs (heteroptera) in brazil that attack tomatoes, being particularly damaging because nymphs and adults feed on both leaves and fruit. gas chromatography (gc) of aeration extracts of adult males vs. females revealed the presence of a male-specific compound. gc-electroantennographic detector experiments indicated that the antennae of females are highly sensitive to this male-specific compound. gc-mass spectrometry and gc-ftir analyses suggested a methyl ... | 2012 | 22723201 |
| heterochromatin characterization in five species of heteroptera. | the amount, composition and location of heterochromatin in athaumastus haematicus (stål, 1859), leptoglossus impictus (stål, 1859), phthia picta (drury, 1770) (coreidae), largus rufipennis laporte, 1832 (largidae) and jadera sanguinolenta (fabricius, 1775) (rhopalidae) are analyzed by c-banding and dapi/ cma fluorescent banding. as the rule for heteroptera the possession of holokinetic chromosomes and a pre-reductional type of meiosis cytogenetically characterize these five species. besides, all ... | 2005 | 16134342 |
| axenic cultivation of a pathogenic phytomonas species isolated from tomato fruit, and from its phytophagic insect vector, phthia picta (hemiptera: coreidae). | axenic cultures of phytomonas sp. were obtained from naturally infected tomatoes and from phthia picta, a predator of tomato plants, by using a biphasic medium with roitman's complex medium overlaying rabbit blood-agar slants. light and electron microscopy of both isolates showed a similarity of morphological characteristics among the flagellates in fresh material or after cultivation. other properties, including their agglutinability with the haemolymph of phthia picta, suggest that these isola ... | 1993 | 8243106 |
| detection of sialoglycomolecules in five plant trypanosomatids and in an insect phytophagous isolate. | the sialoglycoprotein profiles of five plant trypanosomatids (phytomonas spp.) and of one flagellate (herpetomonas sp.) isolated from the salivary gland of a phytophagous insect (phthia picta) were analyzed by western blotting using three distinct lectins (lfa, sna and maa), which recognize specifically sialic acid residues in glycoconjugates. all six flagellates presented at least one polypeptide recognized by the lectins, with the exception of phytomonas françai, which did not show any reactiv ... | 2002 | 12204367 |
