Nitrogen 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...
متن کاملInsecticide Effect of Zeolites on the Tomato Leafminer Tuta absoluta (Lepidoptera: Gelechiidae)
(1) Background: The tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae) is a key tomato insect pest. At present, it is considered to be a serious threat in various countries in Europe, North Africa, and Middle East. The extensive use and the developed resistance of T. absoluta to spinosad causes some concern, which leads to the need for alternative products. (2) Materials and Methods: Sev...
متن کاملInfestation Level Influences Oviposition Site Selection in the Tomato Leafminer Tuta absoluta (Lepidoptera: Gelechiidae)
The tomato leafminer, Tuta absoluta (Lepidoptera: Gelechiidae), is a devastating pest that develops principally on solanaceous plants throughout South and Central America and Europe. In this study, we tested the influence of three levels of T. absoluta infestations on the attraction and oviposition preference of adult T. absoluta. Three infestation levels (i.e., non-infested plants, plants infe...
متن کاملBiological 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 ...
