Book Synopsis Courtship and Mate-finding in Insects by : Raymond J.C. Cannon
Download or read book Courtship and Mate-finding in Insects written by Raymond J.C. Cannon and published by CABI. This book was released on 2023-06-30 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores mate-finding and courtship behaviour in the insect world, in all its subtlety and diversity. Insects engage in courtship as much, or as little, as any other animal; they have songs and dances, and all manner of instruments and ornaments to attract and court the opposite sex. Insects have evolved complex chemical and acoustic communication systems, sending fragrant messages, visual signals and subtle vibrations to attract and persuade. Insects also have many different ways and means of choosing or rejecting mating partners. This beautifully illustrated book shows the incredible variety of courtship behaviours and celebrates the wonderful natural history of a wide range of insects. Varieties of courtship can occur before, during and even after copulation, and numerous examples of the different mating strategies used are presented. This landmark volume will be of interest to students of biology, entomologists, naturalists and anyone with a desire to know more about the love lives of the small creatures with which we share the planet.
Download or read book Sexual Conflict written by Göran Arnqvist and published by Princeton University Press. This book was released on 2013-11-28 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has seen a profound change in the scientific understanding of reproduction. The traditional view of reproduction as a joint venture undertaken by two individuals, aimed at replicating their common genome, is being challenged by a growing body of evidence showing that the evolutionary interests of interacting males and females diverge. This book demonstrates that, despite a shared genome, conflicts between interacting males and females are ubiquitous, and that selection in the two sexes is continuously pulling this genome in opposite directions. These conflicts drive the evolution of a great variety of those traits that distinguish the sexes and also contribute to the diversification of lineages. Göran Arnqvist and Locke Rowe present an array of evidence for sexual conflict throughout nature, and they set these conflicts into the well-established theoretical framework of sexual selection. The recognition of conflict between the sexes is transforming our theories for the evolution of mating systems and the sexes themselves. Written by two top researchers in the field, Sexual Conflict is the first book to describe this transformation. It is a must read for all scholars and students interested in the evolutionary biology of reproduction.

Book Synopsis Deciphering the Genetic Basis of Solanum Chacoense Mediated Colorado Potato Beetle (leptinotarsa Decemlineata) Resistance and Self- Fertility in a Diploid Solanum Chacoense Recombinant Inbred Line Population by : Natalie Kaiser
Download or read book Deciphering the Genetic Basis of Solanum Chacoense Mediated Colorado Potato Beetle (leptinotarsa Decemlineata) Resistance and Self- Fertility in a Diploid Solanum Chacoense Recombinant Inbred Line Population written by Natalie Kaiser and published by . This book was released on 2021 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Colorado potato beetle (Leptinotarsa decemlineata) is the most widespread and destructive insect defoliator pest of potato and its control has historically been achieved through the use of insecticide. The diploid potato species Solanum chacoense has been utilized for over four decades in an attempt to introgress glycoalkaloid-based insect resistance into cultivated tetraploid potato. Despite these efforts, insect resistant cultivars have not been achieved, due in part to the complex genetics underlying the trait. The creation of inbred diploid lines would allow more efficient examination and deployment of this economically important trait. We introduced self-compatibility into diploid insect resistant S. chacoense germplasm and developed the first potato recombinant inbred line (RIL) population to study, understand and deploy this mechanism of host-plant insect resistance in cultivated, diploid breeding lines.We first examined the genetic features underlying leptine glycoalkaloid mediated Colorado potato beetle host plant resistance in the F2 generation derived from a cross between S. chacoense lines USDA8380-1 (80-1) and M6. Using biparental linkage mapping, a major overlapping QTL region with dominant effects was identified on chromosome 2 explaining 49.3% and 34.1% of the variance in Colorado potato beetle field resistance and leptine accumulation, respectively. Bulk segregant whole genome sequencing of the same F2 population detected QTL associated with Colorado potato beetle resistance on chromosomes 2, 4, 6, 7, and 12. Candidate genes within these QTL regions were identified by weighted gene co-expression network analysis of parental lines and resistant and susceptible F2 individuals.Second, we exploited M6-mediated self-compatibility and established vigorous, F5 inbred diploid lines to further examine loci associated with Colorado potato beetle resistance and explore the practicality of inbreeding in diploid potato. F5 inbred lines carrying Colorado potato beetle resistance equivalent to the resistant donor parent were created without field selection during the inbreeding process. We report that the ratio of acetylated to non-acetylated glycoalkaloids measured under greenhouse conditions is a powerful metabolite marker to predict field performance without incurring the costs of conducting a Colorado potato beetle field trial. Leptine production was successfully introduced into diploid breeding germplasm. Single nucleotide polymorphism (SNP) genotyping coupled with stylar analysis of pollen tube growth and self-fertility phenotyping of the F4 and F5 generations revealed that multiple factors mediate the self-compatible response in this RIL population.Third, we assessed the initial transcriptional and metabolite response to Colorado potato beetle herbivory in beetle resistant and beetle susceptible S. chacoense lines over a 48-hour time course. To facilitate genome editing modification of the leptine biosynthesis pathway, we characterized the allelic variation between S. chacoense 80-1 and M6 in a candidate leptine biosynthesis gene identified by transcriptional profiling.This work highlights the challenges of establishing inbred germplasm, reinforces the complexity of selecting for self-fertility in diploid potato, and lays the foundation for optimization of potato RIL development. The availability of highly homozygous Colorado potato beetle resistant lines will enable further genomic inquiry of the loci contributing to this trait and will facilitate rapid deployment of beetle resistant diploid potato varieties.

Book Synopsis Insect Diapause by : David L. Denlinger
Download or read book Insect Diapause written by David L. Denlinger and published by Cambridge University Press. This book was released on 2022-02-03 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.

Book Synopsis Return to Resistance by : Raoul A. Robinson
Download or read book Return to Resistance written by Raoul A. Robinson and published by IDRC. This book was released on 1996 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.
Download or read book Whip Spiders written by Peter Weygoldt and published by BRILL. This book was released on 2021-10-25 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whip spiders (Amblypygi) can be large and terrifying animals with strong, raptorial pedipalps and long antenniform first legs that can produce a span of as much as 60 cm. Others are small and scarcely span 5 cm. They all lead a secretive nocturnal life and are extremely dangerous to other arthropods and small vertebrates. In contrast to spiders and scorpions, they are of no commercial, economic or medical importance and they are difficult to study in the field because of their nocturnal habits, possible reasons why they have been greatly neglected until recently, by scientists and naturalists. Whip spiders represent an old group that dates back to the Carboniferous period. Their partly primitive and partly derived morphological characters and habits make the study of these animals interesting, while observation of their behaviour greatly increases our knowledge and understanding of arachnids in general. In this book the author describes their morphology and systematics, their life history, their fascinating sensory biology, their complex mating dances and reproductive biology, and their ecology and distribution. Thus he has made a significant contibution to a better understanding of the morphology and biology of the Arachnida as a whole. Whip Spiders is an outstanding contribution to science and it will be of interest for anyone with an interest in Arachnida and for those keeping and breeding spiders.
