“…Their toxicity on the larvae inside the mines was so minimal that it can be neglected. Mahmoud et al (2014) stated that lambda-cyhalothrin caused considerable mortality against early larval stages of T. absoluta.…”

Solanaceous plants have a great economic impact in Egypt. These groups of plants include potatoes, tomatoes and eggplants. The new invasive pest of tomatoes, Tuta absoluta (Meyrick) causes the greatest crop losses which can range from 60 to 100%.After its detection in Egypt during the last half of 2009, it spread quickly to all provinces in the country. We aiming to propose a sustainable control program for this devastating pest. In this research we tested three groups of control agents. The first was microbial and natural, the second -plant extracts and the third -chemical insecticides. Our results showed that the impact of T. absoluta can be greatly reduced by the use of sustainable control measures represented by different insecticide groups. Bioassay experiments showed that this devastating pest can be controlled with some compounds that give high mortality rates. Of these compounds, spinosad and Beauveria bassiana, microbial control agents, followed by azadirachtin, gave the best results in controlling T. absoluta. Of the chemical insecticides, lambda-cyhalotrin was the most effective, followed by lufenuron and profenofos. In conclusion we encourage farmers to use microbial and natural control measures in combating the tomato leafminer, T. absoluta, in Integrated Pest Mangement (IPM) programs.

“…Much research has been done on using chemical insecticides for controlling T. absoluta (Colomo et al 2002;Molla et al 2011;Shalaby et al 2012;Mahmoud et al 2014;Deleva and Harizanova 2014). Of the tested chemical insecticides lambda-cyhalothrin was the most effective in controlling T. absoluta.…”

“…Ayalew, (2015) reported that the population of the pest was lower when Diamide® (flubendiamide) and Spinosyns (spinosad) were used than when other pesticides were used to control T. absoluta. Mahmoud et al (2014) reported that Chlorantraniliprole is the most effective chemical in the control of T. absoluta. This result is also in agreement with who conducted research on the efficacy of various chemicals against T. absoluta and found that Chlorantraniliprole is the most effective pesticide.…”

The tomato borer, Tuta absoluta, (Meyrick) has invaded the Mediterranean basin recently from South America and it is becoming a major global pest of tomato. Tomato plants can be infested from seedlings to mature plants. In Loitokitok, the pest has devastated tomato grain in the district with yield loss being reported of up to 100%. This has resulted in loss of income for the tomato growers. Chemical control of the pest has been difficult because the pests live inside the leaves, fruits and stems. Excessive use of pesticide is dangerous can develop resistance due to its high reproduction capacity and short generation. This field study was conducted within Loitokitok in Kajiado County to find out the management practices that tomato farmers are currently using to control Tuta absoluta. The aim was to develop the efficacy of a range of insecticides applied against Tuta absoluta and to assess damage levels caused on tomato. A baseline survey was conducted by use questionnaires to collect data from farmers on the damage level, management measures and their efficacy. The results showed that in Loitokitok, tomato growing can be done up to 3 times/year due to good climatic conditions, which provide the pest with abundant all year round and favours its spread. The insecticides that are commonly used are Coragen* (chlorantraniliprole) Belt* (Flubendiamide), Profecron* (profenofos), Radiant* (spinetorum), Escort* (Emamectin Benzoate), and Pentagon*(Lambda-cyhalothrin). Most farmers were using Coragen due to its specific mode of action on several pests on Lepidoptera group. It has good efficacy against T. absoluta larvae. About 46.37% of the respondents agreed that chlorantraniliprole insecticide used by farmers were effective on the control of pests and farmers were using different insecticides depending on their accessibility and cost. Most farmers recorded the losses of up to 100% tomato yield due to pest attack.

“…According to DuPont TM (2008), use of Chlorantraniliprole causes T. absoluta females to oviposit significantly fewer eggs. Mahmoud et al (2014) reported a reduction in infestation of T. absoluta a day after treatment of plants with Chlorantraniliprole, the infestation would then increase systematically within 2 weeks of treatment. Mahmoud et al (2014) also reported a reduction (95%) on the number of eggs laid by T. absoluta one day after spraying plants, which would then increase three weeks later.…”

The pest has high reproductive potential to the extent that they can have 10 to 12 generations per year under favorable conditions (Illakwahhi et al, 2017).…”

The main purpose of the study was to assess the population growth of the invasive pest Tuta absoluta within Loitokitok district, Kajiado County in Kenya. The study used primary data that was collected from the experiment. The experiment was conducted to assess the population growth of Tuta absoluta. The study showed a variation on the number of Tuta absoluta collected from the protected and unprotected plants when Chlorantraniliprole was used to protect the plants from infestation. The results showed that the total mean number of larvae collected weekly during the period ranged from 1.3±0.6 to 20.8±3.4 in the protected plants and from 4.3±0.6 to 51.7±2.1 in the unprotected plants.
