Chromosome evolution in Lepidoptera
… of chromosome structure across the insect order Lepidoptera, the butterflies and moths. I explore patterns of chromosome evolution across the whole order, and over a short timescale in Polyommatinae, a subfamily of blue butterflies. First, using over 200 chromosome-level genomes, I traced the …

Nocturnal Lepidoptera of Midland Raised Bogs
Raised bogs started to form in Ireland at least 7000 years ago when peat started to accumulate in water-filled depressions left after the last glacial period. Due to centuries of damaging human activities, only 1% of the living, growing active raised bog habitat remains and this is rapidly being …

Hox3 duplication and divergence in the Lepidoptera
… of duplications found in the Hox cluster of the Lepidoptera, called the Special Homeobox genes. An annotation of this duplicated cluster across a wide number of Lepidoptera was performed in order to assess patterns of duplication and loss across the order. The sequences recovered revealed a large …

Orientation of polyphagous lepidoptera to hostplant kairomones
Although in some oligophagous lepidopterans oviposition kairomones from hostplants can also serve as larval feeding stimulants, the relationships in chemistry of attraction of larval and adult stages to hostplants have rarely been examined in polyphagous species. Volatile constituents are known to …

Viruses of Heliothis armigera (Hübner) (Lepidoptera : Noctuidae)
Heliothis armigera (the bollworm) is a pest of agricultural importance in Southern Africa. It is often simultaneously infected with several insect viruses: nuclear polyhedrosis virus (NPV), granulosis virus (GV), and cytoplasmic polyhedrosis virus (CPV). Both NPV and GV have been previously studied …

Advances in tortricid systematics and identification (Lepidoptera: Tortricidae)
The Tortricidae is a large family in the microlepidoptera, consisting of more than 10,300 species in 1,070 genera. Many tortricids are considered to be economically important, and the family contains the highest percentage of pest species in the Lepidoptera. This dissertation provides significant …

The macroecology of Southeast-Asian hawkmoths (Lepidoptera: Sphingidae)
… geographic distribution of the hawkmoth species (Lepidoptera: Sphingidae) of Southeast-Asia and analyses the resulting patterns of biodiversity, biogeography and macroecology. Data on the distribution of species were retrieved from published and unpublished faunal lists and museum collections (in …

Saturniidae (Lepidoptera: Bombycoidea) do Cerrado central do Maranhão
O Cerrado, o segundo maior bioma brasileiro com rica diversidade de espécies endêmicas, tem cerca de 46% de sua mata nativa convertida em cultivos agrícolas e pastagem e, por isso, considerado área prioritária para conservação. O levantamento da fauna é importante para se conhecer e monitorar a …

Maíz Bt : seguimiento de la resistencia de Sesamia nonagrioides (Lepidoptera: Noctuidae) y Ostrinia nubilalis (Lepidoptera: Crambidae) y efectos en artrópodos depredadores
Desde 1999 hasta 2002 se realizó un seguimiento de la resistencia de S. nonagrioides y O. nubilalis al maíz Bt var. Compa CB (derivada del evento 176, que expresa la toxina Cry1Ab) en zonas representativas del cultivo del maíz en España. Para dichas poblaciones se calculó la concentración de Cry1Ab …

Bionomics of Epiphyas postvittana, Ctenopseustis obliquana, Planotortrix excessana (Lepidoptera: Tortricidae) and Stathmopoda "skelloni" (Lepidoptera: Stathmopodidae) on apple cv 'Dougherty' in Auckland
The genus Ctenopseustis Meyrick (Lepidoptera: Tortricidae) is reviewed and the type species C. obliquana (Walker) is redefined. The species C. servana Walker and C. fraterna Philpott are reinstated and the synonomy and characteristics of each species are described and illustrated. Populations of …

Bionomia e etologia do Mocis latipes (Guenee, 1852) (Lepidoptera-Noctuidae)
Data are given on the post-embryonic development under experimental conditions, of Mocis latipes (Guenée, 1852) ,a highly polyphagous species, with marked preference for Gramineas. Data are also given on its ethology.

The Evolutionary History and Conservation of Speyeria Idalia (Lepidoptera: Nymphalidae)
Microsatellite data were concordant with previous analyses in that they indicated the Pennsylvania population was highly differentiated. Moreover, the greater resolution provided by microsatellites indicated the effects of recent habitat fragmentation for Midwestern populations when compared to …
