“…Moreover, this contrasting response of T . solanivora incidence based on rainfall, relative humidity and temperature has been reported previously by Villanueva and Saldamando [ 45 ]. Additionally, in 2016 two genotypes with higher values compared to their susceptible parents were identified, and 20 genotypes showed lower degree of severity than their resistant parent (negative transgressive segregation), indicating a possible genetic overdominance of some loci.…”

Late blight and Guatemalan potato tuber moth caused by Phytophthora infestans and Tecia solanivora, respectively, are major phytosanitary problems on potato crops in Colombia and Ecuador. Hence, the development of resistant cultivars is an alternative for their control. However, breeding initiatives for durable resistance using molecular tools are limited due to the genome complexity and high heterozygosity in autotetraploid potatoes. To contribute to a better understanding of the genetic basis underlying the resistance to P. infestans and T. solanivora in potato, the aim of this study was to identify QTLs for resistance to P. infestans and T. solanivora using a F1 tetraploid potato segregant population for both traits. Ninety-four individuals comprised this population. Parent genotypes and their progeny were genotyped using SOLCAP 12K potato array. Forty-five percent of the markers were polymorphic. A genetic linkage map was built with a length of 968.4 cM and 1,287 SNPs showing good distribution across the genome. Severity and incidence were evaluated in two crop cycles for two years. QTL analysis revealed six QTLs linked to P. infestans, four of these related to previous QTLs reported, and two novel QTLs (qrAUDPC-3 and qrAUDPC-8). Fifteen QTLs were linked to T. solanivora, being qIPC-6 and qOPA-6.1, and qIPC-10 and qIPC-10.1 stable in two different trials. This study is one of the first to identify QTLs for T. solanivora. As the population employed is a breeding population, results will contribute significantly to breeding programs to select resistant plant material, especially in countries where P. infestans and T. solanivora limit potato production.

“…The economic impact of the pest in countries of the Andean area is much more serious than in Central America, mainly because potato is an important family staple and its production is very intensive. Therefore, T. solanivora is considered the most damaging crop insect pest in such countries [15]. Nevertheless, as an insect belonging to Lepidoptera order, the study carried out on the characterization of T. solanivora mitogenome could be applied to other studies on insects considered pest for agriculture.…”

In this chapter, the complete mitochondrial genome of Guatemalan potato moth, Tecia solanivora (Povolny, 1973) (Lepidoptera: Gelechiidae) is presented as a model to understand how to characterize and study a mitogenome in insects. It was sequenced, analyzed, and compared with other lepidopteran insects. T. solanivora mitogenome is a circular double-stranded molecule, typically found in insects and containing 37 genes, all them well described over the other lepidopteran mitogenomes sequenced. Interestingly, in this mitogenome was found a gene arrangement in the tRNA-Met gene different from the ancestral arrangement, but commonly present in insect mitogenomes. Other important characteristics are the high A + T-biased and negative AT-and GC-skews contents, but also unusual canonical start codons in 12 protein-coding genes and an incomplete stop codon in the cytochrome oxidase subunit II gene consisting of just a Thymine. Another common feature shared with lepidopteran mitogenomes is the A + T-rich region. It is characterized by having 325 bb, the 'ATAGA' motif, a 17 bp poly (T) stretch and a (AT) 8 element preceded by the 'ATTTA' motif. Likewise, this mitogenome has 21 intergenic spacer regions. In addition, an update about other recent mitogenomes research done mainly over lepidopteran insects considered crop pests is presented. On the other hand, a novel development based on induced mutations by CRISPR-Cas9 in the mitogenomes seeking applicable capability for pest control is shown. The utility of this study is to improve scientific databases and support future studies of population genetic in lepidopteran.

“…), producing big losses in the field and during commercialization [1]. Although this insect has reduced mobility, it has invaded several countries in Central and South America reaching the Canary Islands in Spain (Europe) in 1999 as described by the European and Mediterranean Plant Protection Organization (EPPO) in the report RS 2001/129 [2] and by Villanueva and Saldamando [3]. In 2015, the pest reached the Spanish Peninsula (Galicia) (EPPO 2015/202; EPPO 2016/131) [4,5] and then Asturias in 2016 [6] (EPPO 2017/080) despite the existence of a European Community Order in which this organism is included in the Annex II, PART A of "harmful organisms whose introduction and propagation should be prohibited in all member states, if present in certain plants or plant products" as modified by ORDEN ARM/1671/2009 of 16th of June referred to RD 58/2005 of 21st January.…”

“…This pest, of rapid dissemination, mainly due to potato trade (seeds and tubers), can cause losses up to 70-80% [3]. It has been classified as one of the most harmful pests because it affects tubers in the field and in the warehouse in countries where potato is an important family staple and production is very intensive.…”

“…According to several authors [1,3] the Guatemalan potato moth is considered one of the most harmful insect pests of potato crops in Central America, Venezuela, Colombia, Ecuador, and Spain (EU) producing 50-70% economic losses. Lara et al [13] pointed out the foreseeable consequences in the Canary Islands from an economic perspective, the loss of traditional farming methods that are a source of income and employment in rural area, and from an environmental perspective, the loss of agro-biodiversity through the disappearance of varieties that are unique in the world, the abandonment of farmland, and a probable change in land use to other activities.…”

Development of a Quarantine Postharvest Treatment against Guatemalan Potato Moth (Tecia solanivora Povolny)

et al. 2021

View full text Add to dashboard Cite

Tecia solanivora is a quarantine organism regarded as one of the insect pests causing major economic losses during potato cultivation and storage in Central America. The potatoes trade between countries, the interest in introducing new potato varieties, the great adaptability of the insect to different agro-ecological conditions, and the globalization world are serious risks in other potato growing countries. This pest was first recorded in Europe in the Canary Islands, Spain, in 1999, later in Galicia (2015) and then in Asturias (2016). Unfortunately, there are no effective chemical treatments for field control, and their integrated management has variable efficacy. Therefore, the implementation of a postharvest treatment to eradicate the insect, at any stage, during storage and marketing of potato becomes essential to achieve a product free of the insect that prevents its dissemination while maintaining the quality during its commercialization. This article presents the development of a new postharvest treatment of potatoes to eliminate all developmental stages of the Guatemalan moth by the application of a control atmosphere enriched in carbon dioxide. Infested potatoes were exposed to different control atmospheres combination (10, 20, 30, 40, or 50% CO2, 20% O2, and rest of N2). These treatments were applied for 4, 7, and 10 days at 18 ± 2 °C. The 10 days duration treatment (30 ± 2% CO2, 20 ± 2% O2 and 50 ± 2% N2) killed the insect in the semi and commercial trials performed without affecting potatoes quality and postharvest life, giving the possibility of its consideration as a quarantine postharvest treatment against T. solanivora.
