Book Description
This fully revised and updated second edition of Insect Pests of Potato now includes an opening section with a basic overview of agronomic and economic issues as they relate to potato production. It also features a new section that reviews potato production, as well as problems caused by insect pests and solutions to these problems, in all major potato-growing regions of the world. Further, a new section discusses theoretical foundations of potato pest management and includes chapters on ecological theory, evolutionary theory, and a case study on their applications to elucidate differences between Eastern and Western populations of Colorado potato beetle in North America. There is also a new chapter on the foundations of integrated pest management and their applications in controlling insect pests. The sections on the biology of main pests and on control methods now feature the latest information, including emphasis on recent advances in molecular biology and genomics. Information on the use of dsRNA technology for pest control is also included, as are new chapters on potato ladybirds and on hemipterous pests other than aphids and psyllids. This second edition provides improved integration and logical connections among chapters and expanded geographic scope of coverage making it the ideal reference on the topic. - Fully revised and updated with new sections on potato-growing regions and theoretical foundations of potato pest management using ecological theory, evolutionary theory and relevant case study insights - Contains improved integration and logical connections among chapters, expanded geographic scope of coverage, and scientific advances - Emphasizes recent advances in molecular biology and genomics, including the use of dsRNA technology for pest control
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

Book Description
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.
