Behavior and oviposition preferences of a black-veined white, Aporia crataegi (Lepidoptera: Pieridae)

POPULATION ECOLOGY Beet Armyworm (Lepidoptera: Noctuidae) Host Plant Preferences for Oviposition

Beet armyworm, Spodoptera exigua (Hübner), oviposition preferences were determined on Þve host plants: cabbage (Brassica oleracea capitata L.), cotton (Gossypium hirsutum L.), bell pepper (Capsicum annuum L.), pigweed (Amaranthus retroflexus L.), and sunßower (Helianthus annuus L.) in no-choice, two-choice, and Þve-choice tests. Tests were conducted in the laboratory, greenhouse, and Þeld cages...

DNA barcodes identify Central Asian Colias butterflies (Lepidoptera, Pieridae)

A majority of the known Colias species (Lepidoptera: Pieridae, Coliadinae) occur in the mountainous regions of Central-Asia, vast areas that are hard to access, rendering the knowledge of many species limited due to the lack of extensive sampling. Two gene regions, the mitochondrial COI 'barcode' region and the nuclear ribosomal protein RpS2 gene region were used for exploring the utility of th...

Some Features of Water Saving in Aporia crataegi L. Caterpillars Inhabiting Areas of Dry Climate in Eastern Siberia (Yakutia, Russia)

Climate in Yakutia is characterized by low winter and hot summer temperatures that cause extreme low air humidity reaching up to 30% in varied periods. Therefore, insects in Yakutia are seasonally faced to extremely dry air that forced them to create special adaptation mechanisms during evolution. Estimation of water balance for Aporia crataegi L. caterpillars was based on measurements of rates...

Phylogenetic systematics of Colotis and associated genera (Lepidoptera: Pieridae): evolutionary and taxonomic implications

We investigated the genetic diversity and phylogenetic placement of the butterflies in the genus Colotis and eight related pierid genera using sequence information from two mitochondrial and two nuclear genes. To establish the status of species, we initially barcoded 632 specimens representative of all genera and most species and subspecies in those genera. A subset was then selected for phylog...
