| study of the pest community of velvetleaf (abutilon theophrasti medic.). | velvetleaf (abutilon theophrasti medicus 1787) is one of the most economically threatening weed plant in hungary. researching biological control against it, and identifying a possible and effective biocontrol agent is an important challenge, as chemical control is difficult and expensive, and there is an increasing claim to practice slight plant protection. entomological studies were made in several parts of the world, for evaluating the species, occuring in velvetleaf, but none of these kind of ... | 2011 | 22696962 |
| effects of precocenes on ovarian development of the seed bug, oxycarenus lavaterae (f.). | antigonadotropic activities of precocene 1 (p1), precocene 2 (p2) and ethoxyprecocene 2 (ep2) on the seed bug oxycarenus lavaterae (f.) (heteroptera, lygaeidae), are reported. ep2 proved to be the most active compound followed by p2 and p1, which agrees with the structure-activity relationships reported for these compounds thus far. mortality in both sexes was furthermore studied. in this context, compound p2 showed the highest degree of toxicity. males, interestingly, appeared to be more sensit ... | 1986 | 3797775 |
| karyotypes, male meiosis and comparative fish mapping of 18s ribosomal dna and telomeric (ttagg) n repeat in eight species of true bugs (hemiptera, heteroptera). | eight species belonging to five true bug families were analyzed using dapi/cma3-staining and fluorescence in situ hybridization (fish) with telomeric (ttagg)n and 18s rdna probes. standard chromosomal complements are reported for the first time for deraeocoris rutilus (herrich-schäffer, 1838) (2n=30+2m+xy) and deraeocoris ruber(linnaeus, 1758) (2n=30+2m+xy) from the family miridae. using fish, the location of a 18s rdna cluster was detected in these species and in five more species: megaloceroea ... | 2011 | 24260641 |
| description of phytomonas oxycareni n. sp. from the salivary glands of oxycarenus lavaterae. | phytomonas spp. (phytomonads) are a diverse and globally distributed group of unicellular eukaryotes that parasitize a wide range of plants and are transmitted by insect hosts. here we report the discovery and characterisation of a new species of phytomonas, named phytomonas oxycareni n. sp., which was obtained from the salivary glands of the invasive species of true bug oxycarenus lavaterae (heteroptera). the new phytomonas species exhibits a long slender promastigote morphology and can be foun ... | 2017 | 28043008 |
