The hormonal control of the development of hairs and bristles in the milkweed bug, Oncopeltus fasciatus, Dall.
The insect cuticle has long been appreciated as excellent material for the study of cellular responses to hormones. Not only is the insect epidermis a single layer of cells, but also ' the tiny fragment of cuticle laid down by a single cell may possess morphological characters controlled by the activities of that cell alone' (Wigglesworth, 1940 a) and cell differences will thus be rendered visi...
متن کاملDynamics of growth zone patterning in the milkweed bug Oncopeltus fasciatus
We describe the dynamic process of abdominal segment generation in the milkweed bug Oncopeltus fasciatus We present detailed morphological measurements of the growing germband throughout segmentation. Our data are complemented by cell division profiles and expression patterns of key genes, including invected and even-skipped as markers for different stages of segment formation. We describe morp...
متن کاملTransovum Transmission of Trypanosomatid Cysts in the Milkweed Bug, Oncopeltus fasciatus
Leptomonas wallacei is a trypanosomatid that develops promastigotes and cystic forms in the gut of the hemipteran insect Oncopeltus fasciatus. Insect trypanosomatids are thought to be solely transmitted from one host to another through the ingestion of parasite-contaminated feces. However, here we show that L. wallacei cysts present on the eggshells of eggs laid by O. fasciatus can also act as ...
متن کاملDevelopment and determination of hairs and bristles in the milkweed bug, Oncopeltus fasciatus (Lygaeidae, Hemiptera).
The term' organule' is proposed as an English equivalent for the German word' Kleinorgan'. The different organules on the third sternite of Oncopeltus are described: larvae possess innervated bristles and special sensilla termed 'chemosensilla', whereas the adult develops, in addition, a dense population of non-innervated hairs. The hairs, bristles and 'chemosensilla' each develop from mother c...
متن کامل04-P012 Germ line specification in the milkweed bug, Oncopeltus fasciatus (Hemiptera)
The body axes of many animals are initially patterned by the asymmetric distribution of maternal mRNAs and proteins in the oocyte. In Drosophila, these maternal factors are synthesized by the 15 nurse cells that connect to each oocyte within the ovary. However, insect ovaries fall into three anatomical categories, of which Drosophila represents only one. The telotrophic meroistic ovaries of the...
