“…The successful integration of the biopesticides in T. absoluta IPM programmes will have a positive impact by reducing the heavy reliance on chemical pesticides to manage the pest, thereby reducing the human and environmental risks posed by their use. Furthermore, by emphasizing the use of biopesticides, T. absoluta resistance can also be minimized (Siegwart et al, ; Tangtrakulwanich, & Reddy, ). Although this study has focused on Kuwait, the results are relevant in other countries in the Middle East, as well as in Asia, Africa, and other parts of the world where greater and widespread use of synthetic pesticides to manage T. absoluta is a dominant trend, and the need to develop environmentally friendly pest control strategies cannot be overemphasized.…”

The tomato leafminer, Tuta absoluta, is one of the most destructive pests of tomato worldwide. Management of the pest is mainly based on chemical insecticides. Reliance on insecticides is difficult to sustain because of unintended long‐term adverse effects on the environment and human health. Consequently, there is a need to develop pest management strategies that ensure the production of high‐quality products, while at the same time ensuring environmental sustainability and maximum consumer protection. We evaluated the efficacy the biopesticides: Azadirachtin, Bacillus thuringiensis, Steinernema feltiae and Beauveria bassiana individually and in combination against T. absoluta under laboratory and greenhouse conditions. When second instar larvae were exposed to tomato leaf discs treated with Azadirachtin (3 g/L), B. thuringiensis (0.5 g/L) or B. bassiana (1.5 g/L), 70%–86%, 55%–65%, and 45.5%–58.5% mortality was observed, respectively. Steinernema feltiae (1,000 IJs/ml) was the least effective biopesticide, with 26%–42% mortality. In the greenhouse trials on tomato, pest infestation (mines/10 leaves/plant) and fruits damaged were significantly lower on plants treated with Azadirachtin + B. thuringiensis or Azadirachtin + B. bassiana compared to plants treated with Azadirachtin, B. thuringiensi, B. bassiana or S. feltiae alone. Azadirachtin + B. thuringiensis and Azadirachtin + B. bassiana resulted in 90% and 81% reduction in fruits damaged in the summer experiments, respectively, and 96% and 91% in winter. The most severe pest infestation was observed on plants treated with S. feltia. The results indicate that the biopesticides, except S. feltia, can contribute to T. absoluta control in greenhouse tomato crops. In particular, the combined use of Azadirachtin with B. thuringiensis or B. bassiana provided the highest level of control of the pest. The potential for including these biopesticides in an overall sustainable integrated pest management programme for T. absoluta is discussed.

“…The strategies vary; these compounds can lower the attractiveness of a plant to insects, make a plant unpalatable [ 18 ], or attract insects to poison them, i.e. , a lure-and-kill strategy [ 19 ], etc. However, the primary result is a reduction in the attractiveness of plants to insects.…”

Only a small percentage of insect species are pests. However, pest species cause significant losses in agricultural and forest crops, and many are vectors of diseases. Currently, many scientists are focused on developing new tools to control insect populations, including secondary plant metabolites, e.g., alkaloids, glycoalkaloids, terpenoids, organic acids and alcohols, which show promise for use in plant protection. These compounds can affect insects at all levels of biological organization, but their action generally disturbs cellular and physiological processes, e.g., by altering redox balance, hormonal regulation, neuronal signalization or reproduction in exposed individuals. Secondary plant metabolites cause toxic effects that can be observed at both lethal and sublethal levels, but the most important effect is repellence. Plants from the Solanaceae family, which contains numerous economically and ecologically important species, produce various substances that affect insects belonging to most orders, particularly herbivorous insects and other pests. Many compounds possess insecticidal properties, but they are also classified as molluscides, acaricides, nematocides, fungicides and bactericides. In this paper, we present data on the sublethal and lethal toxicity caused by pure metabolites and crude extracts obtained from Solanaceae plants. Pure substances as well as water and/or alcohol extracts cause lethal and sublethal effects in insects, which is important from the economical point of view. We discuss the results of our study and their relevance to plant protection and management.

“…These materials contain mixtures of active compounds and have broad or multiple modes of action (Regnault-Roger et al, 2012). Plant essential oils have multiple modes of action and several active components and pests' resistance to them is very lower than conventional pesticides (Tangtrakulwanich & Reddy, 2014). Essential oils from major plant families including Apiaceae, Asteraceae, Lamiaceae, Lauraceae and Myrtaceae have toxicity, repellent, antifeedant, reproduction and growth inhibitory effects against a variety of insect pests (Ebadollahi & Jalali-Sendi, 2015;Isman & Grieneisen, 2014).…”

Tribolium castaneum considered as an economically worldwide insect pest for agricultural and medicinal aspects. Synthetic chemicals have been used in the management of T. castaneum but their residual problems have been renovated the interest in ecofriendly safe materials such as plant essential oils. In the present study, toxicity and antifeedant effects of an essential oil from Melissa officinalis as well-known medicinal plant investigated against T. castaneum. Chemical analysis indicated g-terpinene, carvacrol and a-terpinene were the main components of essential oil. The essential oil showed strong toxicity on T. castaneum adults at several concentrations and treatment times. The LC 50 values were assessed as 19.418, 18.418 and 16.159 ml/l air after 24, 48 and 72 h exposure time, respectively. Sub-lethal concentrations of essential oil caused significant dose-dependent antifeedant activity. Results indicate M. officinalis essential oil can be suggested as a potential alternative to harmful synthetic chemicals.
