The complete mitochondrial genome of the bag-shelter moth Ochrogaster lunifer (Lepidoptera, Notodontidae)
BMC Genomics, 2008Co-Authors: Paola Salvato, Mauro Simonato, Andrea Battisti, Enrico NegrisoloAbstract:Background Knowledge of animal mitochondrial genomes is very important to understand their molecular evolution as well as for phylogenetic and population genetic studies. The Lepidoptera encompasses more than 160,000 described species and is one of the largest insect orders. To date only nine Lepidopteran mitochondrial DNAs have been fully and two others partly sequenced. Furthermore the taxon sampling is very scant. Thus advance of Lepidopteran mitogenomics deeply requires new genomes derived from a broad taxon sampling. In present work we describe the mitochondrial genome of the moth Ochrogaster lunifer . Results The mitochondrial genome of O. lunifer is a circular molecule 15593 bp long. It includes the entire set of 37 genes usually present in animal mitochondrial genomes. It contains also 7 intergenic spacers. The gene order of the newly sequenced genome is that typical for Lepidoptera and differs from the insect ancestral type for the placement of trnM . The 77.84% A+T content of its α strand is the lowest among known Lepidopteran genomes. The mitochondrial genome of O. lunifer exhibits one of the most marked C-skew among available insect Pterygota genomes. The protein-coding genes have typical mitochondrial start codons except for cox1 that present an unusual CGA. The O. lunifer genome exhibits the less biased synonymous codon usage among Lepidopterans. Comparative genomics analysis study identified atp6 , cox1 , cox2 as cox3 , cob , nad1 , nad2, nad4 , and nad5 as potential markers for population genetics/phylogenetics studies. A peculiar feature of O. lunifer mitochondrial genome it that the intergenic spacers are mostly made by repetitive sequences. Conclusion The mitochondrial genome of O. lunifer is the first representative of superfamily Noctuoidea that account for about 40% of all described Lepidoptera. New genome shares many features with other known Lepidopteran genomes. It differs however for its low A+T content and marked C-skew. Compared to other Lepidopteran genomes it is less biased in synonymous codon usage. Comparative evolutionary analysis of Lepidopteran mitochondrial genomes allowed the identification of previously neglected coding genes as potential phylogenetic markers. Presence of repetitive elements in intergenic spacers of O. lunifer genome supports the role of DNA slippage as possible mechanism to produce spacers during replication.

Advances and Challenges of Using the Sterile Insect Technique for the Management of Pest Lepidoptera.
Insects, 2019Co-Authors: Frantisek Marec, Marc J. B. VreysenAbstract:Over the past 30 years, the sterile insect technique (SIT) has become a regular component of area-wide integrated pest management (AW-IPM) programs against several major agricultural pests and vectors of severe diseases. The SIT-based programs have been especially successful against dipteran pests. However, the SIT applicability for controlling Lepidopteran pests has been challenging, mainly due to their high resistance to the ionizing radiation that is used to induce sterility. Nevertheless, the results of extensive research and currently operating SIT programs show that most problems with the implementation of SIT against pest Lepidoptera have been successfully resolved. Here, we summarize the cytogenetic peculiarities of Lepidoptera that should be considered in the development and application of SIT for a particular pest species. We also discuss the high resistance of Lepidoptera to ionizing radiation, and present the principle of derived technology based on inherited sterility (IS). Furthermore, we present successful SIT/IS applications against five major Lepidopteran pests, and summarize the results of research on the quality control of reared and released insects, which is of great importance for their field performance. In the light of new research findings, we also discuss options for the development of genetic sexing strains, which is a challenge to further improve the applicability of SIT/IS against selected Lepidopteran pests.

Inherited Sterility in Insects
Sterile Insect Technique, 2005Co-Authors: James E Carpenter, Stephanie Bloem, Frantisek MarecAbstract:The unique genetic phenomena responsible for inherited sterility (IS) in Lepidoptera and some other arthropods, as compared with full sterility, provide advantages for pest control. Lepidopteran females are usually more sensitive to radiation than males of the same species. This allows the radiation dose to be adjusted to suit programme requirements. When partially sterile males mate with wild females, the radiation-induced deleterious effects are inherited by the F1 generation. As a result, egg hatch is reduced and the resulting offspring are both highly sterile and predominately male. Compared with the high radiation required to achieve full sterility in Lepidoptera, the lower dose of radiation used to induce F1 sterility increases the quality and competitiveness of the released insects as measured by improved dispersal after release, increased mating ability, and superior sperm competition. F1 sterile progeny produced in the field enhance the efficacy of released partially sterile males, and improve compatibility with other pest control strategies. In addition, F1 sterile progeny can be used to increase the production of natural enemies, and to study the potential host and geographical ranges of exotic Lepidopteran pests.

Sex Chromosome Differentiation in Some Species of Lepidoptera (Insecta)
Chromosome Research, 1997Co-Authors: Walther Traut, Frantisek MarecAbstract:Sex chromosome morphology of eight Lepidoptera species was studied, exploiting predominantly the pachytene stage when chromosomes display a remarkable chromomere pattern. Six species had a WZ/ZZ sex chromosome system, one species a W_1W_2Z/ZZ system and one species was of the Z/ZZ type. Much like XY chromosomes in groups with male heterogamety, the Lepidopteran sex chromosomes showed various degrees of structural differentiation. Differences between Z and W chromomere patterns ranged from undetectable to obviously non-homologous. A common property of the W chromosomes (the W_1 in the W_1W_2Z/ZZ system) was the possession of a block of heterochromatin. The heterochromatin block comprised a small or a large segment of the W or even the entire W, depending on the species. Segments with apparent structural homology are evolutionarily young parts of the sex chromosomes — recently fused autosomes that have not had sufficient time for differentiation. The ‘primitive’ Lepidopteran species Micropterix calthella had a Z/ZZ sex chromosome system. This supports the hypothesis that the Lepidopteran W chromosome came into being at the base of the ‘advanced’ Lepidoptera; it was presumably an autosome whose homologue fused to the original Z chromosome.
