| meiotic behavior of 18 species from eight families of terrestrial heteroptera. | insects of the suborder heteroptera are known for their odor, for being pests, or for being disease carriers. to gain better insight into the cytogenetic characteristics of heteropterans, 18 species of terrestrial heteroptera belonging to eight families were studied. the presence of heteropycnotic corpuscles during prophase i, terminal or interstitial chiasmas, telomeric associations between chromosomes, ring disposals of autosomes during metaphase, and late migrations of the sex chromosomes dur ... | 2014 | 25347839 |
| [parasitism of passion fruit bugs in brazil by hexacladia smithii ashmead (hymenoptera: encyrtidae)]. | we describe the new association of hexacladia smithii (ashmead) parasitizing two passion fruit bugs, holhymenia histrio (fabricius) and anisoscelis foliacea marginella (dallas) (hemiptera: coreidae), in brazil. | 2010 | 20498972 |
| feeding preference of holymenia clavigera and anisoscelis foliacea marginella (hemiptera: coreidae: anisoscelini) in relation to intra- and interspecific features of host plants (passifloraceae). | the interactions of holymenia clavigera (herbst) and anisoscelis foliacea marginella (dallas) with their hosts (passifloraceae) in southern brazil are poorly understood. previous studies have indicated that both species use several host species and plant parts and have superior performance on wild hosts. this study evaluated feeding preferences and host plant use under both laboratory and field conditions. choice tests were performed to determine preference for passiflora suberosa parts, prefere ... | 2008 | 19036213 |
| performance consequences of food mixing in two passion vine leaf-footed bugs, holymenia clavigera (herbst, 1784) and anisoscelis foliacea marginella (dallas, 1852) (hemiptera; coreidae). | holymenia clavigera (herbst) and anisoscelis foliacea marginella (dallas) (hemiptera: coreidae: anisoscelini) are distributed in southern brazil and use various passion vine species (passifloraceae) as host-plants. preliminary observations indicate a high coexistence of these species in terms of host-plant use; in addition, there is a strong similarity regarding egg and nymph morphology. in this study, the most suitable feeding sites for nymph performance on wild (passiflora suberosa linnaeus an ... | 2007 | 17505754 |
