“…The activity and intensity of adults trapped depends on temperature (Lacordaire, Feuvrier 2010). The damage was severe at the end of the tomato cycle (Leite et al 2001). These authors always advised farmers to remove the previous crop debris in order to prevent re-infestation of the subsequent crops.…”

The aim of this study was to monitor Tuta absoluta population development in greenhouse conditions on different tomato cultivars. All pest stages were present on all the cultivars. The development of T. absoluta was variable and depended both on temperature and tomato cultivar. Losses due to development of T. absoluta larvae on the fruit were estimated at 43.3% on cv. 'Sahara' , 3% on cv. 'Dawson' , and 17% on cv. 'Toufan' . Percentage of fruit losses was positively correlated with increase in number of larvae. The attacks were more severe during the spring period with rising temperatures. Strong applications of pesticides used to control various tomato pests resulted in absence of antagonists in the greenhouse. Cultivars 'Toufan' and 'Dawson' were less suitable for cultivation in conditions of heavy leaf miner infestation; this characteristic may be associated with other control methods to reduce plant damage.

“…PI 134417) have higher larval mortality, longer larval periods, smaller mines and more females of T. absoluta than on susceptible tomatoes. Leite et al (2001) suggest that this is due to increasing levels of tridecan-2-one as leaves age. Evidence for poor nutritive value of resistant foliage is also suggested from observations of longer pupal development times (suggesting carry-over effects of poor nutrition to the non-feeding pupal stage), whereas observations of lower pupal survival and higher proportions of deformed pupae (i.e., Ecole et al 2001;Leite et al 2001) suggest that some resistant foliage may also contain compounds that are toxic to developing larvae.…”

Similarly, adult P. operculella reared on its preferred host (potato) had lower female egg loading values and lower lipid content, and had a resulting lower tendency to fly when compared to P. operculella reared on a non-preferred host (tomato) (Coll and Yuval 2004), suggesting that adults will more readily disperse away from poor quality hosts.…”

It is likely that whichever cues are involved in stimulating oviposition will also indicate the physiological state (herbivore or disease-stressed) and phenological stage of the host plant allowing females to determine the most suitable hosts for developing larvae.…”

“…Among these, Tecia solanivora (Povolny) feeds exclusively on potato tubers (Dangles et al 2009), whereas Symmetrischema tangolias Gyen and Phthorimaea operculella Zeller feed on both the foliage and tubers of potatoes and related plants (Palacios et al 1999;Horgan et al 2007b). A further species, Tuta absoluta (Povolny), occasionally feeds on foliage of crop potatoes but not on tubers (Campos 1976), and is primarily a problem in greenhouse tomatoes (Ecole et al 2001;Leite et al 2001;Pereyra and Sanchez 2006). Tuber moths will lay eggs directly on exposed tubers in the field (Sileshi and Teriessa 2001) or in rustic potato stores (Das et al 1993a(Das et al , 1993b; however, it is not well understood how populations of S. tangolias and P. operculella on foliage in the field affect subsequent damage to tubers.…”

Insect Pests of Potato

View full text Add to dashboard Cite

Potato, Solanum tuberosum, is the fourth major crop and is grown around the world. It is subject to a large number of insect pests, but the Colorado potato beetle, the potato tuber moths and aphids are the most damaging. Crop resistance to these insects can alleviate problems caused by the use of synthetic insecticides. The diversity of wild tuber-bearing Solanum species offers a source of resistance to insects and pathogens; however, it has so far been under-utilized. This article reviews progress made in the development of insect resistant potato cultivars, as well as the biological and methodological challenges of developing insect resistant potato varieties. We conclude that the prospects of using wild species in future potato breeding programs are good, but, screening and experimental protocols need to be more holistic given the complexity of insect-potato interactions.

BACKGROUND: Host plant resistance plays an important role in integrated pest management programs. Crop resistance assessments commonly focus on only a single dependent variable, such as larval survival/plant damage, which limits the ability to appreciate the impact of host plants on pest populations in the full sense. Therefore, we performed life-table analyses for tomato leaf miner Tuta absoluta, on 19 Solanum lycopersicum genotypes and a wild Solanum habrochaites accession. These analyses assess the ability of the pest to attain a high population density on different tomato genotypes. Based on the resulting ranking of tomato resistance at the vegetative stage (45-day-old plants), we tested the resistance of six selected genotypes at the reproductive stage (4-month-old plants). RESULTS: T. absoluta performance was significantly inferior on vegetative-stage S. habrochaites plants (LA 1777); time taken for the first instars to mine the leaves (5 ± 0.14 days), development time of early-and late-stage larvae (8.8 ± 0.2 and 4.2 ± 0.2 days, respectively), pupal period (11.2 ± 0.58 days), and total developmental time (29.4 ± 0.83 days) were significantly longer, fecundity was significantly lower (18.66 ± 7.24 days), and the highest total mortality (63.33%) also recorded compared with other genotypes, resulting in the lowest net reproductive rate (R 0 ) (11.20 ± 2.51). For the six selected genotypes, the ranking of plant resistance did not change between plants at the vegetative and reproductive stages.CONCLUSION: This study suggested that of 20 screened tomato genotypes, LA 1777 and EC-620343 are the least suitable hosts for T. absoluta to establish fast-growing populations, and thus can be employed in integrated T. absoluta management.
