... insect Oncopeltus fasciatus . We find that in Oncopeltus, even-skipped striped expression initiates in a segmental and not pair-rule pattern. Weak RNAi suppression of Oncopeltus even-skipped shows no apparent pair-rule like phenotype, while stronger RNAi suppression shows deletion of nearly the entire...

... germband insects spans both blastoderm and germband-derived segments. We have cloned the Krüppel homolog from the milkweed bug, Oncopeltus fasciatus (Hemiptera, Lygaeidae),an intermediate germband insect. We find that Oncopeltus Krüppel is expressed in a gap-like domain in the thorax during...

... of the homolog of the Drosophila gap gene hunchback in an intermediate germ insect, the milkweed bug, Oncopeltus fasciatus . We find that Oncopeltus hunchback ( Of'hb ) is expressed in two phases,first in a gap-like domain in the blastoderm and later in the posterior growth zone during germband elongation...

... it was difficult to perform any analysis of gene function outside of the genetic model insects Drosophila melanogaster and Tribolium castaneum . In this paper, we report the use of dsRNA-mediated interference (RNAi) to dissect gene function in the development of the milkweed bug Oncopeltus fasciatus , which has...

...Gerard L. Campbell; Stanley Caveney ABSTRACT A monoclonal antibody that recognizes the product of the segmental gene, engrailed (en) , of Drosophila has been used to analyse expression of the homologous gene of Oncopeltus. engrailed expression in the abdominal segment of larval Oncopeltus...
