“…On potato, T. absoluta only attacks aerial parts, thereby not directly impeding tuber development. Nevertheless, leaf feeding may indirectly lower potato yield and under appropriate climatic conditions, T. absoluta could become a pest for the potato crop (Derbalah et al, 2012 andMaiche, 2009).…”

The experiments were conducted in the laboratory Plant Protection Research Institute Dokki-Giza, to study the effect of Anethum groveolenus Dill, Ambrosia maritime Damaseia extract, Cumminum cyminum Cumin; Syzyguim aromaticum Clove and Allium maritime Garlic on activity of some enzymes in(Tuta absoluta Meyrick) on tomato plants were investigated. After the tested compounds application, the results revealed that these compounds had various effects on the activity alkaline phosphatases, α and β esterases and carbohydrates hydrolyzing enzymes (trehalase, invertase and amylase). The enzyme activity reduced or increased significantly. Activity of alkaline phosphatases, α and β esterases were higher in Damasiea on T. absoluta, in comparison to control. The percentage of increase of alkaline enzymes activity were +22.28 and +17.38 and +13.34 % in T. absoluta respectively. Also, in cumin and garlic extracts treatments. Generally, in case of T. absoluta treatments, the results of damasiea extract indicated high increase (+40.1% in comparison to control) in activity of beta-esterases and invertase enzymes but high decrease (+45.9%), in alpha-esterases activity only. The results indicated that the damasiea extract had direct effects on the metabolism in the body Tuta absoluta.

“…In Egypt, T. absoluta is newly reported and until now there are few registered and recommended insecticides (B.t., IGIs , emamectin benzoate, spinotram, thiomethoxam and chloranitraniliprol) for controlling this insect (EMALR, 2015). However, in Egypt there are going on research work for the evaluation of some insecticides under registration and there were few studies describing the efficiency of some insecticides for the control of T. absoluta (Derbalah el al., 2012;Shalaby et al, 2012;Hanafy and El-Sayed, 2013;Soliman et al, 2014;Ramadan, 2014;Saad et al,2014). Insecticides and their mixtures achieved a considerable reduction of T. absoluta (Soliman et al, 2014;Shiberu and Getu, 2017).…”

Field trials were carried at El-Ashartalaf feddan region, Behaira government, Egypt during two successive seasons of 2016 and 20117 to evaluate four insecticides and three of their mixtures against the tomato leafminer Tuta absoluta under field conditions. The seven evaluated insecticidal treatments were applied in three consequent sprays within an interval of 10 days between each in addition to the treatment of untreated check. The lonely or individually evaluated insecticides included chlorantraniliprole, thiamethoxam, lufenuron and chlorpyriphos which have been sprayed according to the recommendations of the Egyptian Ministry of Agriculture. Meanwhile, their evaluated mixtures: chlorantraniliprole + thiamethoxam, chlorantraniliprole+ lufenuron and thiamethoxam + lufenuronwere were applied at the rate of half recommended dose of each insecticide within the tested mixture. The obtained results showed a more or less toxic efficiency of the individually and/or admixed insecticides against the insect throughout both the seasons of 2016 and 2017. In the first season of 2016, the mixture of chlorantraniliprole + lufenuron was comparatively high effective during the elapsed period after the 1 st and 2 nd spray; furthermore it was proved to be the utmost superior efficient post the 3 rd spray achieving complete infestation reduction (100%) of larvae. During the second season of 2017, chlorpyriphos was the most effective tested individual insecticide. The mixture of chlorantraniliprole + lufenuron was proved again to be superior achieving reduction level of 100% after the 3 rd spray. Therefore, this mixture would be recommended for achieving efficient control of T. absoluta in the growing tomato plants under field conditions. It is also better to use chlorpyriphos alone in IPM program to reduce the costs and slow down the development of resistance of this insect-pest to other involved compounds in the mixtures.Keywords: Tomato plants, the tomato leafminer Tuta absoluta, insecticidal treatments, mixture of insecticides and infestation reduction percentage.

“…Chemical pesticides have long been used as the major strategy for controlling the tomato leaf miner. Over the past decade, a variety of non-chemical methods, such as monitoring, mass trapping, biological control, control of cultural factors, and the use of resistant cultivars, has been developed to control T. absoluta (Desneux et al 2010;Calvo et al 2012;Derbalah et al 2012;Salehi et al 2016;Sohrabi et al 2016a), although efforts to develop more efficient and environmentally safe pesticides and manage the rate of development of pesticide resistance by the pest are underway. In addition, wide application of chemical pesticides is expected to threaten the survival and normal activity of non-target organisms, particularly natural enemies and pollinators, more than the target pest itself, thus negatively affecting production by reducing the efficiency of pollinators and biological control agents (Desneux et al 2007;Martinou et al 2014; Barbosa et al 2015).…”

“…Almost, all aerial parts of tomato plants are attacked by the pest larvae and damage may reach to 100% of yield if no control strategy is taken. The pest status of the tomato leaf miner is largely associated with the high rate of reproduction, whereby each female can lay between 250 and 300 eggs during her life time, as well as the high number of generations, with between 10 and 12 generations produced per year under appropriate climatic conditions (Derbalah et al 2012). Chemical pesticides have long been used as the major strategy for controlling the tomato leaf miner.…”

The damage caused by the tomato leaf miner Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) to 12 tomato cultivars was investigated under greenhouse conditions. The 2 cultivars Korral and CH Falat experienced lower damage in terms of all parameters investigated, whereas the cultivars Valouro and Cal JN3 were categorized as the most susceptible host plants. The larvae feeding on CH Falat and Korral cultivars reached the lowest final weight (1.82 and 1.93 mg, respectively), whereas those reared on the Valouro and Cal JN3 cultivars reached the highest body weight (3.42 and 3.33 mg, respectively). The highest proteolytic and amylolytic activity was detected in larvae feeding on the Korral cultivar, whereas larvae reared on the Valouro cultivar had the lowest enzyme activity for both third and fourth instar larvae. Altogether, the Korral and CH Falat cultivars were classified as relatively resistant cultivars, whereas the 2 cultivars Valouro and Cal JN3 were categorized as highly susceptible to infection by T. absoluta. Therefore, the resistant cultivars can be considered as candidates for use in integrated management programs of the tomato leaf miner in Iran.
