Selective factors affecting clonal variation in the fall cankerworm Alsophila pometaria (Lepidoptera: geometridae)

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

A survey of spatial and temporal variation in the frequency of electrophoretically defined genotypes in the geometrid moth Alsophila pometaria revealed a high diversity of uncommon or rare asexual genotypes and clinal distributions of two of the more common clones. There was substantial year-to-year variation in genotype frequencies in seven of eleven sites. Progeny tests have revealed that sex...

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...

Revision of the genus Pyrochlora Warren , 1895 ( Lepidoptera : Geometridae : Geometrinae )

The genus Pyrochlora Warren is revised and three new species are described: P. motilonia, sp. nov. from Costa Rica and Nicaragua, P. kuklase, sp. nov. from mountainous Ecuador, and P. vogli, sp. nov. from Northern Venezuela. Wings pattern and genitalic structures of all five species are described and illustrated.

A morphological review of tribes in Larentiinae (Lepidoptera: Geometridae)

Tribes of looper moths (Geometridae: Larentiinae) are reviewed. The tribe Dyspteridini Hulst is reinstated (previously synonymous with the Trichopterygini Warren). A new subtribe, Aplocerina, is separated from the Chesiadini Pierce, and the group Ortholithinae Pierce is dealt with as Scotopterygini Warren, the sister taxon to Xanthorhoini. Morphological traits for 22 of 23 larentiine tribes rep...
