Phylogenomic analysis of hemimetabolan insects with emphasis on the hemipteran suborder Auchenorrhyncha and the superorder Paraneoptera
… Thysanoptera, Hemiptera, and Psocodea) and the hemipteran suborder Auchenorrhyncha, which have been hotly debated in the scientific literature due to differences in placement of large and small clades across analyses using different data types. Relationships between and within the …

The ecology, evolution and persistence of an obligate, one-on-one mutualism
… plant (Roridula) and a closely associated hemipteran to determine whether current theories fit this system. More specifically, I determine : 1) whether Roridula is obligately dependent on Pameridea. 2) Whether the exploitational nature of mutualism causes conflict in this system. 3) Whether …

Systematic Studies on the Leafhopper Subfamily Cicadellinae (Hemiptera: Cicadellidae)
… analyses using phylogenetic contrasts of hemipteran body sizes did not show a significant increase in xylem feeding lineages, but results should be viewed cautiously. Sharpshooters host two mutualistic bacterial endosymbionts to complement their poor diet. Phylogenetic analyses were …

EVOLUTIONARY AND MECHANISTIC INTERACTIONS IN VIRUS TRANSMISSION BY APHIDS
Virus transmission by aphids involves a combination of biological players that have co-evolved over years of interaction: plant hosts, aphid vectors, plant viruses and the aphid’s bacterial endosymbiont. In this interaction, plant hosts activate their immune defenses against plant viruses and …
