Comparative Mitogenomic Analysis Of Damsel Bugs Representing Three Tribes In The Family Nabidae (Insecta: Hemiptera), Hu Li, Haiyu Liu, Fan Song, Aimin Shi, Xuguo Zhou, Wanzhi Cai

Entomology Faculty Publications

BACKGROUND: Nabidae, a family of predatory heteropterans, includes two subfamilies and five tribes. We previously reported the complete mitogenome of Alloeorhynchus bakeri, a representative of the tribe Prostemmatini in the subfamily Prostemmatinae. To gain a better understanding of architecture and evolution of mitogenome in Nabidae, mitogenomes of five species representing two tribes (Gorpini and Nabini) in the subfamily Nabinae were sequenced, and a comparative mitogenomic analysis of three nabid tribes in two subfamilies was carried out.

METHODOLOGY/PRINCIPAL FINDINGS: Nabid mitogenomes share a similar nucleotide composition and base bias, except for the control region, where differences are observed at the …

The Complete Mitochondrial Genome And Novel Gene Arrangement Of The Unique-Headed Bug Stenopirates Sp. (Hemiptera: Enicocephalidae), Hu Li, Hui Liu, Aimin Shi, Pavel Stys, Xuguo Zhou, Wanzhi Cai

Many of true bugs are important insect pests to cultivated crops and some are important vectors of human diseases, but few cladistic analyses have addressed relationships among the seven infraorders of Heteroptera. The Enicocephalomorpha and Nepomorpha are consider the basal groups of Heteroptera, but the basal-most lineage remains unresolved. Here we report the mitochondrial genome of the unique-headed bug Stenopirates sp., the first mitochondrial genome sequenced from Enicocephalomorpha. The Stenopirates sp. mitochondrial genome is a typical circular DNA molecule of 15, 384 bp in length, and contains 37 genes and a large non-coding fragment. The gene order differs substantially from …

Inbreeding-Stress Interactions: Evolutionary And Conservation Consequences, David H. Reed, Charles W. Fox, Laramy S. Enders, Torsten N. Kristensen

Department of Entomology: Faculty Publications

The effect of environmental stress on the magnitude of inbreeding depression has a long history of intensive study. Inbreeding-stress interactions are of great importance to the viability of populations of conservation concern and have numerous evolutionary ramifications. However, such interactions are controversial. Several meta-analyses over the last decade, combined with omic studies, have provided considerable insight into the generality of inbreeding-stress interactions, its physiological basis, and have provided the foundation for future studies. In this review, we examine the genetic and physiological mechanisms proposed to explain why inbreeding-stress interactions occur. We specifically examine whether the increase in inbreeding depression with …
