TL;DR: Some species of forest-inhabiting Lepidoptera possess a set of life-history traits including flightless females, larval dispersal by ballooning, polyphagy, univoltinism and overwintering larvae or eggs which contribute to the ability of these species to reach high population density during years favorable to larval growth and survival.
Abstract: -Some species of forest-inhabiting Lepidoptera possess a set of life-history traits including flightless females, larval dispersal by ballooning, polyphagy, univoltinism and overwintering larvae or eggs. Convergence in these life-history traits occurs in species from the Geometridae, Lymantriidae and Psychidae. Ecological factors in the forest habitat which probably contribute to this convergence include habitat stability, resource persistence, convergence in tree chemical defense and phenological variability in bud-break. These lifehistory traits contribute to the ability of these species to reach high population density during years favorable to larval growth and survival resulting in the economic importance of these species. Increased fecundity may be associated with flightlessness, although nutritional studies comparing number of eggs produced in relation to female pupal weight for species with flighted and flightless females must be performed to evaluate this assertion.

TL;DR: Scientists at many institutions are investigating the effects of atomic radiation and chemosterilants on reproduction in Lepidoptera to utilize sterilized insects to control populations as is now being done with the screw-worm fly, Cochliomyia hominivorax, and certain tephridid fruit flies.
Abstract: Scientists at many institutions are investigating the effects of atomic radiation and chemosterilants on reproduction in Lepidoptera. These insects include some of the most destructive pests of agriculture. The ultimate purpose is to utilize sterilized insects to control populations as is now being done with the screw-worm fly, Cochliomyia hominivorax, and certain tephridid fruit flies. Early attempts to sterilize Lepidoptera and other orders of insects emphasized methods that would assure 100% sterility in the insects intended for release.

TL;DR: A comparative genomic analysis shows the deep conservation of the Z chromosome in Lepidoptera and supports a non-canonical origin of the W chromosome and confirms the extreme stability of well-differentiated sex chromosomes.
Abstract: Moths and butterflies (Lepidoptera) usually have a pair of differentiated WZ sex chromosomes. However, in most lineages outside of the division Ditrysia, as well as in the sister order Trichoptera, females lack a W chromosome. The W is therefore thought to have been acquired secondarily. Here we compare the genomes of three Lepidoptera species (one Dytrisia and two non-Dytrisia) to test three models accounting for the origin of the W: (1) a Z-autosome fusion; (2) a sex chromosome turnover; and (3) a non-canonical mechanism (e.g., through the recruitment of a B chromosome). We show that the gene content of the Z is highly conserved across Lepidoptera (rejecting a sex chromosome turnover) and that very few genes moved onto the Z in the common ancestor of the Ditrysia (arguing against a Z-autosome fusion). Our comparative genomics analysis therefore supports the secondary acquisition of the Lepidoptera W by a non-canonical mechanism, and it confirms the extreme stability of well-differentiated sex chromosomes.
