“…Plants respond in different ways to the selection pressures imposed by herbivores (Coley & Barone, ; Walling, ). Although some plant responses, such as plant resistance, are well studied and incorporated into pest management (Vallad & Goodman, ; Alyokhin, ; Pelletier et al , ), others are understudied and underutilised in agricultural systems. One such plant response is plant tolerance, where damaged plants have the same yield or fitness as undamaged plants due to compensatory responses (Strauss & Agrawal, ).…”

“…Potatoes are attacked by a suite of herbivores (Radcliffe ; Pelletier et al ; Giordanengo et al , ), with the main herbivore pest being the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Hare, ; Alyokhin, ). Uncontrolled, Colorado potato beetles can consume 10%–100% of the foliage (Ferro et al , ) and reduce potato yield by 30%–91% with respect to undamaged plants (Senanayake & Holliday, ).…”

Tolerance is a plant response to herbivory that allows plants to sustain defoliation without any fitness consequences. In agriculture, the maximum amount of defoliation that crops can experience without yield loss is defined as the damage threshold. Damage thresholds can be used to develop tolerance-based management strategies, which would offer guidelines for farmers for when pest control should be enacted to minimise pesticide use while maintaining yield. Damage thresholds for many varieties of potatoes, Solanum tuberosum, have been documented, but not consolidated into a general framework. We aggregated data from published studies and quantified the effects of variety, maturity group, life stage and defoliation mechanisms on damage thresholds to inform a tolerance-based management strategy for potato. Late maturing varieties did not have different damage thresholds than early maturing varieties. Damage thresholds were greater than 60% defoliation at emergence and post-bloom and less than 40% defoliation pre-bloom and during bloom. If the stems were damaged, emergence and post-bloom damage thresholds were reduced from 60% defoliation without stem damage to 35% and 52% defoliation with stem damage. Likewise, the damage thresholds during bloom were reduced to 20% defoliation when stems were damaged. We propose using action thresholds based on defoliation as a baseline to develop a tolerance-based management strategy for potatoes.

“…Host plant resistance (a plant's ability to reduce herbivore fitness and deter damage) is regarded as an effective method to reduce the damage caused by herbivores and diseases to crop plants [1][2][3][4][5]. Rice, Oryza sativa L., resistance to planthoppers (Delphacidae) and leafhoppers (Cicadellidae) is one of the best-studied cases of host plant resistance for crop protection [6][7][8].…”

This study examines aspects of virulence to resistant rice varieties among planthoppers and leafhoppers. Using a series of resistant varieties, brown planthopper, Nilaparvata lugens, virulence was assessed in seedlings and early-tillering plants at seven research centers in South and East Asia. Virulence of the whitebacked planthopper, Sogatella furcifera, in Taiwan and the Philippines was also assessed. Phylogenetic analysis of the varieties using single-nucleotide polymorphisms (SNPs) indicated a clade of highly resistant varieties from South Asia with two further South Asian clades of moderate resistance. Greenhouse bioassays indicated that planthoppers can develop virulence against multiple resistance genes including genes introgressed from wild rice species. Nilaparvata lugens populations from Punjab (India) and the Mekong Delta (Vietnam) were highly virulent to a range of key resistance donors irrespective of variety origin. Sogatella furcifera populations were less virulent to donors than N. lugens; however, several genes for resistance to S. furcifera are now ineffective in East Asia. A clade of International Rice Research Institute (IRRI)-bred varieties and breeding lines, without identified leafhopper-resistance genes, were highly resistant to the green leafhopper, Nephotettix virescens. Routine phenotyping during breeding programs likely maintains high levels of

“…The potato tuber moth, Phthorimaea operculella (Zeller), is one of the most damaging insect pests of crop potato ( Solanum tuberosum Grp Tuberosum) worldwide (Rondon ; Pelletier et al. ). The tuber moth causes serious losses to potato production by damaging foliage and tubers in the field and tubers in storage (Rondon ).…”

The diversification of resistant potato varieties at a landscape level could slow adaptation by Phthorimaea operculella to potato resistance and promote sustainable crop protection. In this study, we assessed wild potato species as novel sources of foliage and tuber resistance against P. operculella. Tuber resistance was quantified for 136 and foliage resistance for 54 potato accessions representing 14 and nine potato species, respectively. Several accessions were highly resistant to moth damage in tubers and/or foliage. In particular, Solanum chiquidenum and Solanum sandemanii were highly resistant to damage in tubers. Several accessions of Solanum multiinterruptum and a small number of accessions of Solanum bukasovii, Solanum berthaultii, Solanum sparsipilum and Solanum wittmackii also had highly resistant tubers. Larval survival on foliage of S. bukasovii and S. chiquidenum was generally low. New resistance sources are listed, and insect performance on the plants is described with possible resistance mechanisms. The study also examined potential trade-offs associated with resistance. Tuber resistance was negatively correlated with the number and weight of tubers produced per plant, but positively correlated with the length of dormancy across accessions, indicating that, although long dormancy is not a prerequisite for resistance, species and accessions with extended dormancy will have more resistant tubers. Tuber and foliage resistance were generally positively correlated across all accessions; however, among accessions from within a potato species, there were negative (S. berthaultii), positive (S. chiquidenum) and non-significant (S. bukasovii) relations. These results indicate that, besides identifying novel resistance sources, an improved understanding of the mechanisms and inherent trade-offs associated with tuber and foliage resistance will improve the efficiency of potato breeding programmes aimed at enhancing resistance against P. operculella.
