Transovum 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 s...
