AbstractThe tomato leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae), is a widespread devastating pest reported to develop on economically important solanaceous crops. The characterisation of its host range could help to understand and prevent the dispersion behaviour of the insect in the environment. In this study, the ability of T. absoluta to develop on 12 cultivated or non-cultivated plants including Solanaceae, Amaranthaceae, Convolvulaceae, Fabaceae, and Malvaceae species under laboratory conditions was assessed. For each plant species, we monitored the development times of immature stages, survival, sex ratios, and adult fecundity rates. All the six tested non-solanaceous plants, including Chenopodium Linnaeus (Amaranthaceae), Convolvulus Linnaeus (Convolvulaceae), and Malva Linnaeus (Malvaceae) species, were not able to sustain (i.e., allow growth and development) T. absoluta larvae. Solanum Linnaeus (Solanaceae) species were the most suitable host plants for the pest, but others could be opportunistically colonised with fewer incidences. Tuta absoluta appears to be strongly related to solanaceous plants that would predominantly support self-sustaining field populations. Preventing crop infestation by removing potential host plants in the immediate field vicinity and culture rotations with non-solanaceous crops is of primary importance.

Cassava Mosaic Virus

Abstract Cassava is vegetatively propagated therefore ACMV and other CMGs are primarily transmitted via movement of contaminated cuttings. Consequently, introductions of specific CMGs into new localities mirror patterns of cassava cuttings exchange among farmers. Once infected cuttings are planted, the virus establishes easily and can be transmitted within and between fields through the feeding behaviour of the whitefly vector, Bemisia tabaci. ACMV is particularly invasive in that it is the most widespread of all known CMGs, occurring across all cassava-producing countries of Africa in cassava and several alternative host plants (Thottappilly et al., 2003; Alabi et al. 2015). ACMV has also been reported infecting non-cultivated exotic cotton species in Pakistan (Nawaz-Ul-Rehman et al., 2012) further underscoring its invasive nature. Yield loss due to CMD can range from 12 to 82%, depending on the cassava variety and infection type (Owor et al., 2004). ACMV is not on the IUCN or ISSG alert list.

Abstract Twelve selected cultivated or wild solanaceae (Solanum dulcamara, Solanum nigrum, Solanum villosum, Solanum lycopersicum, Solanum muricatum, Solanum melongena, Datura innoxia, Datura metel, Physalis spp., Capsicum annuum, Nicotiana alata, and Petunia spp.) (all species Solanales: Solanaceae) were tested as potential alternative host plants against Solanum tuberosum for a local population of the Colorado potato beetle Leptinotarsa decemlineata Say (CPB) in Estonia. Some CPB populations in America and southern Europe accept most of these plants. However, geographically isolated populations of beetles can differ in their acceptance of new host plants. Migrants from the southern Europe supplement Estonian beetle population regularly, so individuals may differ in their host plant preferences. S. melongena and S. dulcamara were well accepted by the beetles, Lycopersicum spp. (Solanales: Solanaceae) and N. alata were intermediate, and S. villosum and S. nigrum were least accepted. The beetles rejected S. muricatum, Physalis spp., C. annuum, Petunia spp., and D. metel. First-instar larvae completed a full life cycle only on S. dulcamara, N. alata, S. lycopesicum, S. melongena, although their development rate was slower, mortality was higher and emerging adults were underweight relative to those that fed on S. tuberosum. The fourth-instar larvae were less sensitive in relation to food. We found that S. dulcamara as a native plant could provide resources for CPB during early and late season. At the same time, the cultivated S. melongena would be suitable plant species for further testing as dead-end crop for integrated pest management.
