The Origin and Distribution of Clonal Diversity in Alsophila Pometaria (lepidoptera: Geometridae).

Survivorship and Growth of Sexually and Asexually Derived Larvae of Alsophila pometaria (Lepidoptera: Geometridae)

Variation in Population Sex Ratio and Mating Success of Asexual Lineages of Alsophila pometaria (Lepidoptera:Geometridae)

Populations of Alsophila pometaria (Harris) are largely gynogenetic and composed of asexual females that must mate with a conspecific male to reproduce. Within this asexual contingent, there are a variety of electrophoretically defined multilocus genotypes. In this study we found that populations differ in sex ratio. We also found that there is an indication of differential mating success among...

Phylogeographic Diversity of the Winter Moths Operophtera brumata and O. bruceata (Lepidoptera: Geometridae) in Europe and North America

The European winter moth,Operophtera brumata (L.), an invasive forest defoliator, is undergoing a rapid range expansion in northeastern North America. The source of this invasion, and phylogeographic diversity throughout its native range, has not been explored. To do this, we used samples from a pheromone-baited trap survey of O. brumata collected across its native range in Europe, and invasive...

The geometrid moths of Ethiopia I: tribes Pseudoterpnini and Comibaenini (Lepidoptera: Geometridae, Geometrinae).

In this paper we present a checklist for Ethiopian Geometridae, subfamily Geometrinae, tribes Pseudoterpnini and Comibaenini. Six species were found to belong to the tribe Pseudoterpnini, two species to the tribe Comibaenini. One species is described as new, Comibaena theodori sp. nov. Adults of all species are illustrated, genitalia are figured for the new species.

Evaluation of pheromone-baited traps for winter moth and Bruce spanworm (Lepidoptera: Geometridae).

We tested different pheromone-baited traps for surveying winter moth, Operophtera brumata (L.) (Lepidoptera: Geometridae), populations in eastern North America. We compared male catch at Pherocon 1C sticky traps with various large capacity traps and showed that Universal Moth traps with white bottoms caught more winter moths than any other trap type. We ran the experiment on Cape Cod, MA, where...
