Wolbachia infection shared among planthoppers (Homoptera: Delphacidae) and their endoparasite (Strepsiptera: Elenchidae): a probable case of interspecies transmission

, 2001
Wolbachia , a group of parasitic bacteria of arthropods, are believed to be horizontally transmitted among arthropod taxa. We present a new probable example of interspecies horizontal transmission of Wolbachia by way of an endoparasite based on the ...

Biology of the planthopper Sogatella vibix (Haupt) in Giza, Egypt (Hom., Delphacidae)

Deutsche Entomologische Zeitschrift, 1977
Biology of the planthopper Sogatella vibix was studied on wheat seedlings in the glasshouse in Giza, Egypt. At 16–21 °C egg incubation period averaged 16.8 ± 0.09 days. At various temperatures incubation period range from 7–47 days. Total nymphal duration averaged 14.2–15 days at 22–30 °C, and 41.8–43 days at 11–20 °C, with no significant difference ...
