ITS2 as a molecular marker for the identification of Diatraea saccharalis and D. flavipennella and possible infection with Cotesia spp.
Bombyx mori pylorus infection by Alphabaculovirus
Alphabaculovirus is an entomopathogenic virus genus that infects Bombyx mori, which is known as the Bombyx mori multiple nucleopolyedrovirus (BmMNPV). This virus is polyorganotrophic, and a series of tissues are known as targets; however, there is currently no information regarding infection in the pylorus, the segment of the hindgut that is present in the midgut transition and is responsible for food passage control. Thus, in the present study, we aimed to analyze infection of the B. mori pylorus by BmMNPV. To do so, hybrid B.
Cells of the rectum of Bombyx mori affected by experimental inoculation with Alphabaculovirus
Bombyx mori is an insect whose cocoon is used in the sericulture industry, which is an important activity in parts of southern Brazil. When parasitized by Bombyx mori nucleopolyhedrovirus (BmNPV) of the genus Alphabaculovirus (alphaBV), it develops nuclear polyhedrosis disease. In Brazil, an alphaBV was isolated from larvae of B. mori and various target tissues were identified. However, how this geographic viral isolate affects the rectum of silk moths was unknown.
Complete mitochondrial genomes of the Bright Sunbeam Curetis bulis and the Small Copper Lycaena phlaeas (Lepidoptera: Lycaenidae) and their phylogenetic implications
In this study, the complete mitochondrial genomes of Curetis bulis and Lycaena phlaeas were determined and analyzed. The circular genomes are 15,162 bp long for C. bulis and 15,280 bp long for L. phlaeas, with a total A+T content of 82.6 and 83.1%, respectively. Both mitogenomes contain 37 genes, and their gene orders are similar to those of other lepidopterans.
DNA barcode information for the sugar cane moth borer Diatraea saccharalis
We reviewed the use and relevance of barcodes for insect studies and investigated the barcode sequence of Diatraea saccharalis. This sequence has a high level of homology (99%) with the barcode sequence of the Crambidae (Lepidoptera). The sequence data can be used to construct relationships between species, allowing a multidisciplinary approach for taxonomy, which includes morphological, molecular and distribution data, all of which are essential for the understanding of biodiversity. The D.
