Biological aspects of tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae) in conditions of Northeastern Tunisia: possible implications for pest management
The tomato leafminer Tuta absoluta Meyrick is a key insect pest of tomato in Tunisia and in many other countries around the world. The present study was carried out to attempt to acquire better knowledge of the biology of this insect and to implement suitable prophylactic control tools for T. absoluta in Northeastern Tunisia. Under greenhouse conditions, T. absoluta females exhibited a stronger...
متن کاملBiological Activity of some Natural Plant Extracts and Bio-Pesticides against Tomato Leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) and their Residues on Tomato Fruits
Five new pesticides were evaluated for their effectiveness in the control of Tuta absoluta (Meyrick), (Lepidoptera : Gelechiidae) on tomato plant. The effect of pesticides against egg and larvae were estimated after 2, 5 and 7 days from application. The highest reduction percentage of eggs of Tuta absoluta during two successive seasons achieved by Emacit (81.25 and 74.5) % respectively after 7 ...
متن کاملRNA interference as a gene silencing tool to control Tuta absoluta in tomato (Solanum lycopersicum)
RNA interference (RNAi), a gene-silencing mechanism that involves providing double-stranded RNA molecules that match a specific target gene sequence, is now widely used in functional genetic studies. The potential application of RNAi-mediated control of agricultural insect pests has rapidly become evident. The production of transgenic plants expressing dsRNA molecules that target essential inse...
متن کاملBiological invasion and biological control select for different life histories
Biological invaders have long been hypothesized to exhibit the fast end of the life-history spectrum, with early reproduction and a short lifespan. Here, we examine the rapid evolution of life history within the harlequin ladybird Harmonia axyridis. The species, once used as a biological control agent, is now a worldwide invader. We show that biocontrol populations have evolved a classic fast l...
متن کاملNitrogen and water availability to tomato plants triggers bottom-up effects on the leafminer Tuta absoluta
This study examined the effects of various levels of nitrogen inputs (optimal, insufficient and excessive) and water inputs (optimal, low drought and high drought) to tomato plants (Solanum lycopersicum) on survival and development of an invasive tomato leafminer, Tuta absoluta (Meytick) (Lepidoptera: Gelechiidae). Plant growth i.e. plant height and the number of nodes declined under insufficie...
