“…Adults can move from potato fields into potato storage facilities and back to potato fields (Povolný, 2004). They make short flights close to the ground during the night, and shelter in shady places on the ground, on bushes and weeds at the edges of fields, and under leaf litter or between potatoes in potato storage facilities at daytime.…”

This pest survey card was prepared in the context of the mandate on plant pest surveillance (EFSA-Q-2017-00831), upon request by the European Commission. The purpose of this document is to assist the Member States in planning annual survey activities of quarantine organisms using a statistically sound and risk-based pest survey approach, in line with the current international standards. The data requirements for such activity include the pest distribution, its host range, its biology, risk factors as well as available detection and identification methods. This document is part of a toolkit that consists of pest-specific documents, such as the pest survey cards and generic documents relevant for all pests to be surveyed, including, the general survey guidelines and statistical software such as RiBESS+.

“…Nowadays this tuber moth is considered widely distributed in the Neotropical region, where the reported economic losses have been as high as 100% . The species started to spread overseas (by means of seed distribution) in 1999, and it is expected to reach mainland Africa and establish in Europe in the years to come . Insecticide use against this species, especially in invaded areas, led to emerging problems of insecticide resistance and increased risks of insecticide control failure .…”

“…The aim of this study was first to test if populations of the potato tuber moth T. solanivora in the Colombian territory bearing a previously known (altered target‐site) mutation for resistance to a pyrethroid insecticide were also resistant to other insecticides commonly used in potato crops. Subsequently, after identifying two key populations – one nearly susceptible to all tested pesticides (or only marginally resistant, if no susceptible was available), and one resistant to organophosphates and pyrethroids – we recorded and compared their life history traits under pesticide‐free conditions to assess if life history trade‐off and fitness cost are expressed.…”

BACKGROUND Resistance to pesticides is an evolutionary process that entails, in most cases, substantial consequences to the biology of the resistant populations. In this study we focus on the life history traits of the potato tuber moth Tecia solanivora, an invasive and voracious pest for which resistance to pyrethroid insecticides was recently reported. Marginally resistant and multiple‐resistant populations were selected from eight sampled localities in Colombia; the use of a fully susceptible population was not possible since none was recognized in the laboratory or field. The multiple‐resistant Siachoque population exhibited a 42‐fold resistance to the carbamate insecticide carbofuran, and low levels of resistance to chlorpyrifos, a trend observed in six of the eight tested populations. This population also exhibits 24‐fold resistance to permethrin. The marginally resistant population of Gualmatán showed 4‐fold resistance to chlorpyrifos. RESULTS The multiple‐resistant population exhibited a 3.8‐day shorter developmental time than the susceptible population, but with higher larval mortality. The peak of egg‐laying was delayed in the resistant population in 9 days and the population growth rate was lower than that of the susceptible population. CONCLUSION We hypothesize that the short developmental time of the multiple‐resistant population may be an adaptation to minimize exposure to insecticides, which are applied to the soil. This adaptation is likely to require the surviving adults to compensate for the smaller nutrient amounts accumulated by the larvae in investing part of its adult life in securing the necessary resources for late‐life egg production. © 2018 Society of Chemical Industry

“…The 1993 paper was little known, and subsequent authors continued to use the name T. solanivora (Povoln y). Povoln y published two more papers in 2004 (Povoln y, 2004;Povoln y and Hula, 2004) using the name S. solanivora; but later, authors still continue to use T. solanivora.…”
