Paraphyly of Homoptera and Auchenorrhyncha inferred from 18S rDNA nucleotide sequences
Morphological, palaeoentomological and eco‐evolutionary factors supporting the 18S rDNA‐based phylogenetic tree are discussed and four principal hemipteran clades are identified.
Description of a Species of Bemisia (Homoptera: Aleyrodidae)
The species has been demonstrated to be distinct from B. tabaci (Gennadius) by crossing experiments, studies on intraspecific and interspecific mating behavior, analysis of allozymic frequencies, PCR analysis of genomic DNA, and morphological evaluation.
Evolutionary origin of whiteflies (Hemiptera: Sternorrhyncha: Aleyrodidae) inferred from 18S rDNA sequences
Phylogenetic analysis of 18S rDNA nucleotide sequences of hemipteran exemplars shows Sternorrhyncha (psyllids, whiteflies, aphids and scales) is monophyletic and forms a sister group to all other…
A range extension of Homalodisca coagulata (Say) (Hemiptera: Clypeorrhyncha: Cicadellidae) to southern California.
First record of Glycaspis brimblecombei (Moore) (Homoptera: Psyllidae) in North America: initial observations and predator associations of a potentially serious new pest of eucalyptus in California.
California mealybugs can spread grapevine leafroll disease
This study examined the ability of mealybugs, a putative leafroll vector, to transmit this group of viruses and confirmed that four species found in California — obscure, longtailed, citrus and grape mealybug — can transmit GLRaV-3 isolates.
Non-monophyly of Auchenorrhyncha ("Homoptera"), based upon 18S rDNA phylogeny: eco-evolutionary and cladistic implications within pre-heteropterodea Hemiptera (s.l.) and a proposal for new…
Analysis of Morphological Variation in Distinct Populations of Bemisia tabaci (Homoptera: Aleyrodidae)
Observations indicate that morphological characters of pupae are not useful alone for classifying individuals from B. tabaci or B. argentifolii populations.
