Cross resistance in the brown planthopper, Nilaparvata lugens Stal (Hemiptera: Delphacidae)

Japanese journal of applied entomology and zoology, 1987
The topical toxicities of eight insecticides in susceptible (S), malathion-resistant (Rm) and fenvalerate-resistant (Rmf) strains of the brown planthopper were determined. The negatively correlated cross resistance was observed between malathion and fenvalerate. The insecticidal activity of fenvalerate (racemic) wholly depends on that of fenvalerate A.

Phylogenetic position of the yeast-like symbiotes of Tagosodes orizicolus (Homoptera: Delphacidae) based on 18S ribosomal DNA partial sequences

Revista de Biología Tropical, 2004
Tagosodes orizicolus Muir (Homoptera: Delphacidae), the endemic delphacid species of tropical America carries yeast-like symbiotes (YLS) in the abdominal fat bodies and the ovarial tissues, like other rice planthoppers of Asia.

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 ...

Evolutionary aspects of acoustic communication in Ribautodelphax planthoppers (Homoptera, Delphacidae)

Delphacidae (Homoptera), commonly referred to as planthoppers, are herbivores, which usually feed on grasses and sedges. During sexual behaviour males and females communicate by exchanging low-frequency vibrational signals, which are transmitted through the substrate, normally the host plant.
