The Tomato Borer Tuta Absoluta Meyrick (Lepidoptera, Gelechidae) Invading The Region of Ouargla (Desert of Algeria): Biology and Damage

Abstract Tuta absoluta (Meyrick) is an invasive pest of tomato native to South America, where it is responsible for extensive damage. The study of this bioaggressor under greenhouse tomato in the region of Ouargla by pheromone traps showed that the global dynamics of populations T. absoluta 5 shows the difference in successive generations of six months is the growth cycle of tomato. There were a maximum of 1922 individuals in the three greenhouses studied. The life cycle of T. absoluta in tomato plants (T: 34 ° C H%: 50 - 60%) lasts 23.85 days. This pest has caused losses of up to 100% in leaves and fruits of tomato in February. Observation and direct capture to identify the natural enemies of T. absoluta as Chrysoperla carnea Coccinella algerica. and the parasitoid Trichogramma sp. Damage is directly related to the reduction of plants photosynthetic capacity and of production levels in tomato crops; indirect damage can be also caused by secondary infections, with pathogens developing on the infested plant and fruit tissues.

And Control

Globally, fungal inocula are being explored as agents for the optimization of composting processes. This research primarily evaluates the effects of inoculating organic vegetable heaps with the entomopathogenic fungus Clonostachys rosea f. catenula (Hypocreales) on the biophysicochemical properties of the end-product of composting. Six heaps of fresh cabbage (Brassica oleracea var. capitata) waste were inoculated with C. rosea f. catenula conidia and another six were not exposed to the fungus. The composted materials from the fungus- and control-treated heaps were subsequently used as a medium to cultivate tomatoes (Solanum lycopersicum). The biophysicochemical characteristics of the composted materials were also assessed after composting. In addition, the protective effect of the fungal inoculum against red spider mite (Tetranychus urticae) infestations in the tomatoes was evaluated through the determination of conidial colonization of the plant tissue and the number of plants infested by the insect. Furthermore, phytotoxicity tests were carried out post experiment. There were few significant variations (p < 0.05) in heap temperature or moisture level between treatments based on the weekly data. We found no significant differences in the levels of compost macronutrient and micronutrient constituents. Remarkably, the composted materials, when incorporated into a growth medium from fungus-treated heaps, induced a 100% endophytic tissue colonization in cultivated tomato plants. While fewer red spider mite infestations were observed in tomato plants grown in composted materials from fungus-treated heaps, the difference was not significant (χ2 = 0.96 and p = 0.32). The fungal treatment yielded composted materials that significantly (p < 0.05) enhanced tomato seed germination, and based on the phytotoxicity test, the composted samples from the heaps exposed to the C. rosea f. catenula inoculum were not toxic to tomato seeds and seedlings. In conclusion, this study showed that C. rosea f. catenula improved the quality of composted materials in terms of fungal endophytism and seed germination.

Successive Generations

The role of root channels in the occupation of deep soil profiles by jarrah (Eucalyptus marginata Sm.) forest in south-western Australia was explored by coring and excavation. In profiles derived from granite, major descending roots are confined to channels that extend vertically from fissures and conduits in the shallow subsurface caprock layer deep in the clay subsoil. The channels are permanent features of the profile and are occupied by successive generations of trees. The channels have a diameter of 1-300 mm, abundance of 3 5 m-2 (all channels) or 1 m-2 (large channels), and occupy 1% of a horizontal surface at 6 m. Each forest tree has potential access to 100-200 channels. Large roots, fine roots with root hairs, and decaying root remains occur in the channels. Only fine roots (less than Imm diam.) penetrate the clay matrix and occupy the entire profile down to basement at depths of up to 40 m. In profiles derived from dolerite, occupation of the deep clay by large and fine roots is diffuse and root channels are absent. The dissimilar mode of root occupation of the two profile types may be explained by the difference in bulk density. In providing avenues for access by large roots as well as preferential wetting, the root channels may play a dominant role in the water and salt balance of jarrah forests on the granitic profile.

Objective:This study reassesses the generational disparity in immigrant offending. Patterns and predictors of offending are compared using traditional peer-based models and an alternative within-family (parent–child dyad) model.Method:The National Longitudinal Survey of Youth (1979; NLSY79) and NLSY-Child and Young Adult (NLSY_CYA) data are merged to create an intergenerational data set to compare generational disparities in immigrant offending across peers and within families. Differences in self-reported offending (prevalence and variety) by immigrant generation are assessed using a combination of descriptive analyses (χ2and analysis of variance) and regression models.Results:While NLSY_CYA children generally are at a greater risk of offending compared with the NLSY79 mothers, the difference in offending is greatest between first-generation mom and second-generation child dyads. Disparities in offending are driven in large part by exceedingly low levels of offending among first-generation immigrants.Conclusion:Although the factors driving an increase in offending between parent–child generations are not unique to immigrants, they are amplified in immigrant families. Whereas the second generation is remarkably similar to their U.S.-born counterparts in terms of their involvement in crime, suggesting a high degree of swift integration, the greater involvement in crime among the children of immigrants compared to their foreign-born mothers suggests a decline in well-being across successive generations.

Not At Risk

International crop exchange always brings the risk of introducing pests to countries where they are not yet present. The invasive pest Tuta absoluta (Meyrick 1917), after taking just a decade (2008–2017) to invade the entire Africa continent, is now continuing its expansion in Asia. From its first detection in Turkey (2009), the pest has extended its range of invasion at a very high speed of progression to the southeast part of Asia. This study adopted the cellular automata modelling method used to successfully predict the spatiotemporal invasion of T. absoluta in Africa to find out if the invasive pest is propagating with a similar pattern of spread in Asia. Using land cover vegetation, temperature, relative humidity and the natural flight ability of Tuta absoluta, we simulated the spread pattern considering Turkey as the initial point in Asia. The model revealed that it would take about 20 years for the pest to reach the southeast part of Asia, unlike real life where it took just about 10 years (2009–2018). This can be explained by international crop trade, especially in tomatoes, and movement of people, suggesting that recommendations and advice from the previous invasion in Europe and Africa were not implemented or not seriously taken into account. Moreover, some countries like Taiwan and the Philippines with suitable environmental condition for the establishment of T. absoluta are not at risk of natural invasion by flight, but quarantine measure must be put in place to avoid invasion by crop transportation or people movement. The results can assist policy makers to better understand the different mechanisms of invasion of T. absoluta in Asia, and therefore adjust or adapt control measures that fit well with the dynamic of the invasive pest observed.
